Any ideas? Done 150k 2.2 TDI only mod is blanked off EGR for the last 50k. Everything else original. Oil & all filters replaced 5k ago only been hunting for 1k.

Hunting is only really noticeable when cold on startup until it warms. Rattles a bit at the same time almost as if it were a petrol engine with too much advance.

Still as smooth as new when warm and goes well. Fuel consumption has dropped from usual 50 to 45 but that could just be the crappy winter derv we still have here .

Cheers!
