Ford SID212 AdBlue & DPF Deletion

Remapping the SID212 ECU to delete AdBlue and DPF functions, or to increase power, can’t be done due to the high level of encrypted ECU security being used.

Deleting DTCs in the separate AdBlue ECU still results in the EML coming on, as does removing the DPF, because some of the codes are stored in the Engines SID 212 ECU.

Ford SID 212 AdBlue & DPF Deletion

This unique device is permanently installed to the vehicle and automatically selects and repeatedly deletes any SID 212 NOx and DPF codes, therefore keeping the EML and the Engines Limp Mode off.

Should any new unselected, or more important OBD codes occur, the OBD X BOX pauses deleting, allowing the EML to come back on so that any unrelated DTC’s can still be investigated.

SID212 ECU AdBlue and DPF Deletion

AdBlue and DPF Removal is illegal???

Removing the AdBlue system or DPF from a vehicle in the UK is said to be illegal and breaking the law, although exactly which law is very unclear.

There are no case histories we are aware of claiming owners have been prosecuted for such an offence.

The OBD X BOX has been developed for use as an emergency Ford SID 212 AdBlue and DPF get you home device. IT DOESN’T REQUIRE THE REMOVAL OF ANY PART OF THE VEHICLES ADBLUE OR DPF SYSTEM (unless completely blocked) for it to keep the vehicle legal, out of limp mode, and still driveable.

The OBD X BOX can be permanently installed, but if removed, the vehicle and its Engine Management ECU will revert back to standard.

There isn’t currently any ECU software remapping solution to delete the AdBlue system or DPF function from the Ford SID 212 ECU, or to remap it for more power.

Most of the industry’s leading remapping companies have tried but failed. Some have managed to read the SID 212 ECU, write the modified software changes, upload the file, BUT THE ENGINE WON’T START.

A separate AdBlue ECU is used on this recent SID 212 application (Since late 2019) and has now been cracked by most Remapping Companies. Although the AdBlue function can at last be deleted, it still causes the EML to come on, ultimately resulting in the vehicle going into limp mode and eventually not starting.

Installed near to the rear of the exhaust system, and after the SCR Catalyst, is an NOx sensor that monitors the content of NOx gases (Oxides of Nitrates). When the amount exceeds a permissible value, the SID 212 ECU, and not the AdBlue ECU, logs a pending DTC. This eventually turns into a registered DTC, leading to the EML coming on, shortly followed by limp mode. This coincides with an error message on the dash indicating after how many miles the engine will be prohibited from starting.

If the DPF is also removed, this results in an incorrect pressure differential DTC and P2442 is usually logged, initially as pending, but soon after as registered and eventually resulting in limp mode. A further DTC relating to poor DPF efficiency is also logged causing frequent DPF regeneration attempts due to an assumed high DPF soot fill level. Installing an OBD X BOX to the vehicle solves both these problems and avoids any large repair bills which can often be several thousands of pounds at the Main Dealers.

Ford SID 212 AdBlue & DPF repairs using the OBD X BOX

BEFORE DELETING THE ADBLUE SYSTEM OR REMOVING THE DIESEL PARTICULATE FILTER, THE FOLLOWING OPTIONS SHOULD BE CONSIDERED.

The OBD X BOX can also be used to help repair faults with the vehicles AdBlue and DPF System whilst saving you time and money on unnecessary parts replacement.

When a vehicle’s been standing unused for even a short time, faults often occur due to crystallization of the AdBlue Urea Fluid as well as solidified carbon deposits to parts of the vehicles Exhaust Emissions System and DPF.

Any present DTC’s (Diagnostic Trouble Codes) will stop the AdBlue system from working and the SID 212 ECU from regenerating the DPF. Most codes start off as pending, therefore the Engine Management Light may not illuminate so the driver won’t be aware of any faults.

Common system faults include.

Perfectly functioning NOX sensors stop working because they’re contaminated by carbon deposits, if the DPF were to complete its regeneration there’s a good chance these sensors would recover due to the very high exhaust gas temperatures reached and de-carbonizing effect.

A sticking AdBlue injector will cause Urea fluid leakage from the injector pintle resulting in low Urea pump system pressure. Repeatedly deleting any relevant DTCs using the OBD X BOX with the engine running allows the ECU to start pulsing the injector again, this sometimes rectifies this common fault and saves having to fit a new injector.

Slow and lazy AdBlue pumps can’t achieve the correct desired pressure in a specified time, resulting in the EML coming on. By repeatedly deleting any DTCs, and the ECU continually switching on the AdBlue pump whilst the engine is running sometimes kickstarts and recovers these often expensive to replace in tank pumps.

A restricted DPF or even blocked SCR causes a high differential pressure sensor reading which prevents the ECU from regenerating the DPF. Using the OBD X BOX to repeatedly and quickly delete any relevant DTCs allows the Ford SID 212 ECU to continually attempt and to eventually, if possible, regenerate the DPF.

Using the OBD X BOX to quickly and repeatedly delete any DPF trouble codes allows you to drive a restricted vehicle out of limp mode using its maximum available power. This previously unavailable method really helps when using carbon dissolving chemicals to clean restricted or blocked DPF’s before attempting to regenerate them.

Disabling The AdBlue System Isn’t Always That Easy

Unlike all other AdBlue deletions routinely carried out by Technicians using one of many software providers, the SID 212 solution is different. On this latest SID 212 ECU it’s not possible to just delete the AdBlue system, it must be in a working state first before disabling it. Whilst this is much easier on a fully functioning system it still means faults must be repaired or any failed components emulated before disabling the system. This of course means there’s a diagnostic procedure which must be carried out before attempting any re-mapping, any workshop time should be factored into your final repair costs.

The OBD X BOX Is Available Only To Diagnostic Specialists

Some Re-mappers are only interested in simple, quick, and trouble free remaps, sometimes including DTC deletions or AdBlue and DPF solutions. To be an approved installer of the OBD X BOX you must have the technical ability and Ford Specific (For Scan or the latest Snap-On Scanner or similar) diagnostic equipment, and be able to diagnose, repair and re-set AdBlue and DPF related faults and all ECU adaptions. Most vehicle owners only request a deletion when there’s already a fault with their AdBlue or an error message displaying Engine No Start in 31 or 500 miles. There can be many reasons for this, anything from a low AdBlue fluid level to a system component failure, a misreading NOX sensor or even a failed SCR in the exhaust system. The normal Main Dealer procedure is to diagnose any AdBlue fault(s) and to repair them in the usual way, this often proves very expensive.

Part of our solution is to bench read (TSM) the AdBlue ECU and send the file to one of our file providers requesting an AdBlue delete file. We’ve used custom SID 212 AdBlue delete files from several sources and up to now had a 100% success rate.

Bench Programming Using TSM Method
The delete re-map includes modifying the AdBlue flow rate and Urea level, deleting specific DTCs and other mods not disclosed by some companies. A list of all the fault codes that must be deleted in the AdBlue ECU are listed here:

P1397 – P1501 – P1726 – P2044 – P2045 – P2047 – P2048 – P2049 – P205C – P205D – P206A – P206B – P206C – P206D – P208A – P208B – P208C – P208D – P208E – P209F – P20A0 – P20A2 – P20A3 – P20A5 – P20B9 – P20BA – P20BB – P20BC – P20BD – P20BE – P20BF – P20C0 – P20E8 – P20E9 – P20EA – P20EB – P20FE – P20FF – P21CB – P21CC – P2BA8 – U0100 – U0400 

Note:  as far as we are aware, any other AdBlue related codes not included in the above list for the AdBlue remap should appear in the vehicles OBD. If some other Hard Fault Codes were to appear in Manufacturer Specific Only, (not in OBD) then as these can’t be deleted from the SID 212 ECU, these faults would still have to be diagnosed and repaired in the usual way.

Once you’ve re-mapped the AdBlue ECU with a delete file, cleared all the DTC’s and Reset the Fault Inducement Chain using For Scan, Snap-on, or something equivalent, the vehicle is ready for its Adaptive Drive Cycle.

NOTE: If there are any Engine Management trouble codes whatsoever present the SID 212 or AdBlue ECU, the AdBlue system may not reset itself on a drive cycle, any DTC’s in either OBD or vehicle specific must be cleared.

Sometimes, if you’re lucky, the orange AdBlue icon and error message indicating how many miles left before the engine won’t start may just go out. If it doesn’t, you may have to drive the vehicle for between 10 and 30 miles (or even more) until the AdBlue and SID 212 ECU are satisfied and both the AdBlue and DPF systems are working as they should. There seems to be no pattern to this, sometimes the icon goes off on its own with the engine running, other times it disappears after KOEO (Key On Engine Off)

NOTE: even on vehicles where the DPF’s inner contents have been removed, we know these systems will still re-set as long as both DPF Exhaust Gas Temp Sensors are connected and are confirmed to be working as normal in live data on your Scan tool.

If during the Adaptive Drive Cycle any Pending or Registered codes were to occur, the AdBlue adaptation would stop, and the whole process would have to be re-started. To prevent this, the OBD X BOX should be connected to the OBD port before the drive cycle for it to automatically request and continually delete any pending or registered OBD codes.

The DTC delete refresh rate must be set at once per second (1Hz) and the DTC delete frequency also at once per second (1HZ) in the OBD X BOX settings. The default delete frequency is 5Hz which is the frequency to select when leaving it on the vehicle.

If you hardwire the OBD X BOX and choose to mount it discreetly, you may wish to take advantage of 2 more advanced features we’ve included.

After this re-set procedure has been successfully carried out the OBD X BOX must be left connected to the OBD port where it automatically continues deleting any Pending or Registered OBD codes.

NOTE; When leaving it connected directly to the 16 pin OBD port instead of hard wiring it, make sure you apply some extra tension to the male connector pins. This is easily done by bending the pins slightly inwards from the Centre of the connector to ensure a good connection.

The OBD X BOX emits a 100ms long bleep when initially connected to the 12-volt power supply of the OBD port. This feature is used to check the OBD port connection, if it’s faulty, a bleep will sound every time you “wiggle” the plug, confirming a poor connection at the plug. If you wiggle it and it doesn’t bleep, the connection is good.

The OBD X BOX Can Also Be Hardwired

This is the preferred option, and although we can supply a Hardwire Kit including solderless connectors, these are difficult to connect to the SID 212 equipped OBD ports. The best way to install the OBD X BOX is still to solder directly onto the 4 wires at the back of the OBD port. This involves removing and separating the security gateway plastic housing and drilling a small hole for the wires to exit. The wiring configuration is simple to follow once you’ve chopped off the male connector from the main OBD X BOX harness and connected the wires from behind the port as a mirror image of the male 16 pin connector plug you’ve just cut off, it’s that simple!

16 pin connector
VERY IMPORTANT – YOU MUST READ THIS

To prevent the risk of the vehicle’s battery going flat overnight, or when left for longer periods, make sure the vehicle is always kept locked. Because the BCM shares the same fused power supply as the OBD port, it may stay awake at times, resulting in a flat battery.

To prevent this, you can connect the OBD X BOX red power supply wire on pin 16 of the OBD port to an ignition live source instead. Find one ideally that’s not shared with the Body Control Module, when left wired permanent live through the OBD port, and with the vehicle always staying locked, the battery can’t go flat.

The OBD X BOX retains all its original DTC delete settings when the 12 Volt power supply is restored so it doesn’t need reprogramming.

If It Doesn’t Work Now, You’ve Wired It Wrong

You really shouldn’t need technical help with this, think about it, it worked when you plugged it into the OBD Port, so it should still do now.

Discreetly connecting 4 wires to the back of the OBD port reduces the risk of the OBD X BOX being accidentally left disconnected and the EML coming back on.

The OBD X BOX can be programmed so that for up to 255 secs from ignition on (plus sleep time, 80 seconds) there isn’t any OBD connection attempt to the vehicles ECU. This feature allows for an uninterrupted OBD Scan tool connection to be made without the user being aware an OBD X BOX is installed to the vehicle.

NOTE: The OBX X BOX has an inbuilt non-volatile memory so that it can be removed from the vehicle, when re-installed it restores its previous settings.

Your AdBlue Delete Solution Is Now Complete

When is the Best Time to Delete the AdBlue System?

Without doubt the best time to delete it is whilst the system is still operating normally and without any warning lights on the dash. An AdBlue delete remap should still be installed to future proof any component or circuit failures, but the AdBlue Reset won’t be as complicated at this time.

Disabling the AdBlue System Without Remapping the ECU

This is only an option when there are no warning lights or messages on the dash and the AdBlue system is in full working order. You must make sure the AdBlue tank is at least 50% full to prevent any future low fluid level warning messages.

First you must disconnect the AdBlue injector 2 pin plug in the engine bay and secure it so it can’t interfere with any moving parts. Now connect the AdBlue injector emulators 2 wires to the 2-wire connector of the injector socket (ECU Side) using the solderless connectors supplied (the wires can be connected any way round). The Emulator simulates an AdBlue injector and prevents the SID 212 ECU from registering an open circuit injector fault.

Installing an Emulator on its own isn’t enough to disable the AdBlue system, after a short drive cycle the EML will come on for NOx related and high AdBlue pressure DTC’s, resulting in Limp Mode.

The OBD X BOX prevents Limp Mode by deleting DTC’s as pending codes and keeping the EML off, this also stops you having to reset the AdBlue system.

The ideal method is to still re-map the AdBlue ECU, so be prepared that without an AdBlue delete, any future system faults could cause a mileage non-start time out message that you may still get blamed for.

DPF Removal, EGT Emulation and DTC Deletion

When removing the DPF we strongly recommend you also remove the pre-cat above the DPF, these are prone to failure due to excessive AdBlue overdosing, saturation and crystalizing, often resulting in a loss of power. Without the SCR catalyst there’s an increase in NOx levels, ultimately leading to the SID 212 ECU switching on the EML and soon followed by limp mode, the OBD X BOX easily deals with this.

Before removing the DPF you must still check the AdBlue system is functioning correctly and there aren’t any DTC’s or any mileage timeout messages on the dash display.

Part of our DPF deletion process requires the installation of 2 Exhaust Gas Temperature emulators to the engine bays ECU wiring harness, these simulate a DPF core temperature of approximately’ 700 degrees. At this temperature the ECU believes that passive DPF regeneration is in progress and prevents further DPF regens These emulators should be installed using the solderless Tap It connectors supplied in the kit, and as they’re not polarity sensitive the wiring configuration doesn’t matter.

NOTE: With the 2 emulators installed you may notice on longer journeys a pending DTC appears for excessive high exhaust gas temperatures, this is due to us simulating a high EGT temperature. So long as you’ve selected the Auto Capture, Add and Auto Delete function in the OBD X BOX settings, this code will automatically clear without Limp Mode or the EML coming on.

After removal, you must program the vehicle’s ECU to tell it a new DPF has been fitted and re-set the DPF soot fill counters.

This 2-piece Exhaust Gas Temperature emulator (EGT) kit is available as an extra when removing Diesel Particulate Filters. You simply attach both the 2 wire EGT sensors with the 2 wire emulators using the solderless connectors in the Hardwire Kit. 

OBD X BOX Final Set Up and Road Test

It makes no difference if you’ve deleted AdBlue, the DPF or both, the OBD X BOX settings are the same before you carry out the final road test.

Leave the default settings as they are, the DTC request frequency is set at 1Hz and the delete frequency at 5Hz. The OBD connection delay is set at 0 Seconds which is suitable for most applications.

Make sure you select the Auto DTC Capture and Delete button so that you don’t have to select and add DTC’s yourself to the Auto Delete list.

If you hardwire the OBD X BOX and choose to mount it discreetly, you may wish to take advantage of 2 more advanced features we’ve included.

You can set the OBD connection delay for up to 255 seconds to allow the priority communication of another Garages scan tool. You can also disable in software the piezo sounder that bleeps when DTCs are detected and when a delete message is being sent. So long as you leave the OBD X BOX sounder in the ON POSITION you will be able to activate the sounder test to hear where you’ve discreetly placed the unit.

Finally, check to make sure the OBD X BOX does go into sleep mode so it’s not keeping other modules awake, resulting in a possible flat battery. When in sleep mode, the LED will be off for 5 seconds and blink for 0.2 seconds, sleep mode will not operate if the unit is still connected to a PC, it must first be disconnected.

When using the OBD X BOX for the very first time we recommend you watch the very informative You Tube training video by Wayne Schofield of Chipwizards here.

How Much does the OBD X BOX Kit Cost?

The only 2 components you will need to leave on a vehicle when deleting the AdBlue system are the main OBD X BOX module and the 16 pin OBD cable. These come as a boxed pair at an introductory trade price of only £300.00 Plus Vat.

For your first AdBlue or DPF deletion you will need to purchase from us a Bluetooth module that connects to a laptop or PC so you can program an OBD X BOX. You wouldn’t normally leave this on a vehicle unless you had to be very discreet and wanting to make some adjustments with the customer present. The trade price of the Bluetooth module is only £35.00 plus vat.

For your initial purchase we suggest you order a hardwire installation kit which only costs £10.00 plus vat and is handy to carry in stock should you need it.

Never mind what you think, should you or shouldn’t you remove the DPF, sooner or later you will be in that predicament, trust me it will happen. For the sake of just £35.00 plus vat you may as well just order an Exhaust Gas Temp Emulator Kit and have it in stock.

Does it Cost Extra To Remap the AdBlue ECU?

Yes, it does, if you are already an Engine Remapping Dealer you should already know what the costs are for AdBlue deletion files. If you are an independent garage you will have to contact an Engine Remapping Company to discuss the many options, they could offer you.

How Much Are Deletions To The End User?

As suppliers of the OBD X BOX we don’t set the costs to the end user, but we do recommend our installers a minimum price they should charge. The AdBlue deletion cost should be no less than £950.00 plus vat and the cost of DPF deletion no less than £1250.00 plus vat. When both deletions are carried out at the same time the minimum suggested cost could be reduced to be £2000.00 plus vat, as only one OBD X BOX is required for both solutions. Because the OBD X BOX is the only available solution, skilled installers should be able to charge a premium.

Viezu SID 212 Diesel Tuning Box

To improve fuel economy and driveability on our SID 212 OBD X BOX Ford Transit Demo Vehicle, we’ve installed a Viezu Diesel Tuning V Box as the SID212 ECU can’t be remapped for power and economy either. Customers having their AdBlue or DPF’s deleted often ask for a power remap, only because that’s what they had with their previous vehicle’s deletions.

We chose Viezu because they are a reputable company and joint second largest ECU remapping and tuning company in the UK (alongside Quantum Tuning), if not Europe. Their Plug and Play Tuning Box should still be fitted by a Diesel Specialist because diagnostic tests must first be carried out and ECU adaptions reset after. Once installed, the V Box is trouble free and requires no maintenance, the power and driveability is like that of good ECU remap.

The Viezu Tuning Box, also known as the Viezu V box, comes ready mapped and programmed for the Ford 2.0 TDCI engine fitted to the Ford Transit from about 2019 onwards. The Viezu V Box SID 212 is also compatible with the Ford Ranger, Mondeo, Focus and Kuga.

When you purchase a Viezu Diesel Tuning Box that’s custom programmed to your Ford SID212, it’s tuned on the conservative side so there’s no chance of the EML coming on. Power can be further increased by adjusting the Viezu Diesel Tuning V Box’s dip switches, but there’s a possibility the EML may come on due to Fuel Rail Pressure Sensor DTC’s. This can be due to desired and actual rail pressures varying slightly under hard acceleration.

Viezu

Installing an OBD X BOX for this symptom allows you to select and delete these codes whilst still in their pending stages, and without the EML coming on. The OBD X BOX allows you to experience the maximum power increases available throughout the RPM range from a Viezu Diesel Tuning V Box fitted to your vehicle.

So, when installing a Viezu V Box to a Ford SID212 ECU equipped Transit, Ranger, Mondeo, Focus or Kuga, you can be assured you’re fitting the best Diesel Tuning Box available.

Any OBD X BOX approved installer wishing to purchase Viezu Tuning Boxes should contact Viezu directly and negotiate their own Dealer terms.
