Speed Limit Programming

Many modern light commercial vehicles have the facility built into the engine electronics ECU that allows us to programme / set the speed limit.

We can programme the speed limit on many different light commercial vehicles this saves you having to purchase an expensive add on after market speed limiter.

DPF/FAP Cleaning & Regeneration

In some cases we may be able to revive your DPF / FAP filter by performing a special cleaning process and after that performing a regeneration.

DPF/FAP Replacement

We now can supply and fit replacement DPF filters new and remanufactured for a huge range of makes and models .

Also when you replace the DPF the ECU needs to be reset and sometimes also needs a software update and as we have invested in OE softwares we can also provide this services which up until now could normally be only performed by the main dealer

Our Specialist Diagnostic Centre will also check for problems which may be causing your dpf to block.

Immobiliser Decoding

All modern vehicles from about 1995 onwards have a built in immobiliser system.  Problems with your immobiliser system can be caused by many issues, from key fobs that have lost their coding, key fobs with lost transponder chips, damaged or corroded wiring, faulty ECUs, can bus errors, corrupt body ECUs, faulty BSI units, damaged receiver rings and so on.

On certain vehicles we can completely bypass the immobilizer system.  Please enquire so we can check if your vehicle is one that the immobilizer system can be bypassed(in most cases we will need ecu makes and numbers to check this for you) and if it is one that cannot be bypassed we can diagnose and repair the immobilizer system.

Please note for this service we will need written permission from the vehicle owner and proof of vehicle tax book and drivers licence.

ECU Virginising

On most vehicles that have an inbuilt factory immobilizer system the engine ECU is coded to the immobilizer system and the manufacturers say that once the ECU is married to that specific immobilizer system it is married to the system for life so this means that if the engine ECU fails on your vehicle you cannot replace it with a second hand one as the manufactures and generic diagnostic tools will not allow you to recode a used ECU.

With other programming and eeprom reading writing devices we can in a lot of cases virginise the ECU (this means that when we do this the ECUs immobiliser system is in a new unmarried state) can be reprogrammed with a diagnostic tool that has the capabilities.

In other cases we can read the immobiliser data from the faulty ECU and write it to the used ECU so then it can be fitted to the vehicle without any programming.
