Now, I know there are multiple threads going around the Internet concerning this, but haven't seen any on here and am polling for others...
So, to recap:
170BHP engines with DPF (not just limited to Passats) are having issues whereby the DPF is not re-generating correctly and when taking it to a ******* they are replacing the exhaust pressure sensor and "updating" the ECU software . The effect of updating the software is reportedly reduced power, and some are even reporting that it is limiting the engine to 155BHP.
Certainly VW customer services are aware of an issue with certain batches of Passat (mine included) and they are asking the ******** to follow a precise set of instructions to correct the fault. My DPF/Engine Mgmt light has been on twice now in 6 months, and unfortunately for myself, the 2nd time it was in for repair (4 days ago), they updated the software as part of that repair process. My car now lacks any punch whatsoever in 1st and 2nd, even my wife has noticed it. Motorway cruising lacks that infamous 170 punch when florring it. The turbo seems almost non-existent, first gear has even less punch than it had before (which was poor originally!). It just seems like a flat ol' diesel now :mad:
It is back in the dealer tomorrow, and I am fearing that they will say "no faults found", although I think tempers will flair.
There have been a plethora of reports on the Golf, Seat & Audis...but have an interesting read of this http://uk-mkivs.net/forums/t/264896.aspx
So...be aware and make sure they do not update your software!
