DPF on 1.9 PDs

[horace1664]

Which 1.9 PDs (if any) have a DPF fitted?

Thank you in advance.

None that i know of, only the newer 170bhp 2.0 engines.

Indeed. No 1.9 ever had a DPF. It was only something introduced to more recent 2.0 TDIs. The early 2 litres got away without having them. I suspect it was around 05/55plate they started appearing. The 1.9s never had more than a cat which could easily be ripped out

Thank you guys.

Will a de-cat throw up any faults?

No.

Just back pressure problems if your car is like mine.

shouldn't be back pressure issues. TDIs don't want any back pressure in the exhaust because the turbos produce sufficient amounts themselves. A freeflowing exhaust "should" give the best results, but maybe some people are finding the opposite is true? I wouldn't be without my "pipe" exhaust now.

Mine spluttered and stalled on take off without a CAT, so i put it back on. Mine seems to be the only one i've heard of, but i'm happier with it back on.
