My 09 Audi A4 2.0 tdi ust recently developed a problem with the emissions .
The engine management, glow plug ,and particulate filter lights all showed up on my dash. The turbo is currently turned off ,cruise control is not working, engine is limp!
I have replace the pressure sensor on the DPF ,done a regeneration ,but still no improvement! Just wondering if there are any other sensors that would perhaps be faulty?
Would be greatful for some professional help !

can you get scan done ? or buy an autel vag505 or similar to read the codes ?

Thanks Niall for the reply ,

I've had a scan completed and it showed up p2002 and p2463 codes which I think refers to soot in the DPF . However, I've done a few forced regen without any luck . Replaced the pressure sensor ,but I was wondering if any of the other sensors could be faulty without the scan detecting it ?

Did you scan for faults before you replaced the sensor? What was the ash loading of the dpf? If you replace the sensor then it needs to be adapted bencore you carry out a regeneration.

Yeah the scan was done before I replaced the sensor . The ashload was initially 35 ,but was reduced to 20 with a regen . Still nothing improved in terms of the turbo switching off .
