Well - now I'm not so sure it's my imagination. Followed an 07 320d from 50 to 70 ish today and there was virtually no difference. I was in 4th so I imagine he would have been too - I doubt he was in 3rd judging by the fact that no smoke was billowing from the exhaust (it was a down-turned pipe like mine).

I decided to check the jumpers and min has a red jumperon the bottom which is 3 pins from the left and a blue one on top which is 3 from the right (I'm looking at it face-on with the circuit board underneath the pin block). I was quite surprised to see this as others have said that theirs is on pin 4 or 5 from the right So I thought I'd move the bottom one (red) one pin to the right to see what happens.

Started the engine and let it idle for a minute (no instruction on whether this is necessary, but was erring on the side of caution). Started fine, no black smoke - seemed happy. Then I took it for a spin and it now seems quicker at the top end but with more lag at the low end. The net result is quicker but you have to drive it like a petrol!

Can anyone else confirm their jumper settings and whether you have red and blue jumpers like mine?

Will probably speak with Mike during the week to try and get to the bottom of it because it's a bit of a mystery at the moment...
