Hi guys, i have a problem with my 2.5 tdi v6
From 1000rpm to 2000rpm when i floor on idle or whatever its so slow. I asked my friend mechanic, he said it could be a some vacuum leak. Did anyone had any problem like this? What could be a problem.
But when turbo kicks in its okay then.
And guys, when i put in in first gear and try to go without the gas, between 800-900rpm (idk really), something in engine is knocking. But when its over 1000rpm its fine,nothing knocks.
