Since we had this remapped we've noticed the boost isn't smooth anymore...
Now we don't do many miles in it so its not really a mega issue but I like things right...
When we had it mapped it was winter so didn't really notice if it was there before or after...
So... the engine is a AUM...
If you floor it in 1st, 2nd... it seems to pull well, into 3rd, 4th, or 5th, seems to boost hard, then off alittle, then boost hard again, then off alittle through the rev range... ( Like it over boosts, then cuts back, then over boosts etc )
Down the motorway in 5th it just does your head in!!!
I've got no faults on the dash display and am getting nowt on Vagcom...
I've replaced the N75 valve today and put another new standard dump valve on... just because I have a stock of new spares lol...
Anyone got any ideas?
I'm gonna pop Audi in the morning and check what part numbered N75 valve it should have on incase there's a difference?
If not i'm gonna try another map on it?
The car idles fine, starts fine... drives lovely bar this issue... I don't have a boost gauge plumbed in so am only guessing its over boosting...
