dumpvalve
Funny, the 2.0 170 diesel engine has a butterfly on the inlet, alot like a petrol car, so it would benefit greatly from a dumpvalve. Could be a waste of money in some peeps eyes, but then again i want one.
Sure you have spent a fortune on your 330 bhp oil burner. which is still a diesel tractor. Most peoples view of you would be a pleb spending all that money on a combine harvester, when everyone else would just buy a s4 an have done with it.
Just out of interest, who did the work on your car?
