Important info on the 2.0 TDI 170 PD engine

The 2.0 TDI 170 engine which can be found in many of the VAG cars is very prone to DPF problems and as such is one of the most popular engines to perform DPF removal on. This particular engine carries a Siemens PPD ECU (rather than a Bosch found in many similar engines with DPFs) and has caused problems for companies (including us in the past) when trying to delete the DPF code from the ECU in order for the DPF removal to work successfully.

Part of this is down to the additional patches that VW placed inside the ECU. After the 2.0 TDI 170 engine was released into the market, many of the DPF’s were failing almost straight away and VW added additional code in order for the DPF to regenerate more often. Removing all of this code is no simple task, when compared with the other Bosch ECU’s, as the additional code is located elsewhere in the ECU.

During our research and development on these engines we too experienced problems with the DPF removal ECU software. Initially the software would seem to work but no more than 100 miles later the DPF light would return and the vehicle would try and regenerate, sometimes causing limp home mode and reduced engine power. Be warned, this can cause damage to your engine! We have now received information from Siemens themselves in order to get the software 100% right on this car and complete a successful DPF removal. This software also works on cars with dashboard lights which are illuminated because of the DPF, fault codes and faulty pressure sensors. Take a look around on the internet at all of the people now experiencing problems with their DPF removal on this vehicle.

If you have a 2.0 TDI 170 vehicle then you should think very carefully about where you take your car before having the DPF removed!

    Im having trouble with my DPF filter, I have a ford focus 1.6 TDCI(110) 55 reg. The initial problems where with the fluid levels, i got those topped up to the sum of £350! then less then 2 months later my EGR Valve went(i was told) got that replaced £350) now im being told my DPF filter has to be changed! a garage managed to do something but after 1 day, the engine management light as come on again. Is there anything i can do to get this fixed at a cheap cost? steam clean? removal of the filter.
