I have a oct tdi 110 bhp the problem is that below 3k revs there is no go in the car, over that revs it gos no problem. I have had the vnt looked at and changed the n75 valve.

Would any1 know anything else thats common with this?

cheers

:bump:

no takers for this problem? basic problem is big flat spot until 3k revs then loads of boost!!

I have no idea, hence the bump!

something really weird going on with the MAF maybe? any chance of getting any MAF diags from vag-com?

Or VNT still stuck, and hense only working at >3000 rpm?
