02' A4 (B6) (bone stock)
Very sluggish, can't get out of it's own way until 3500-4000 rpm. Boost is absent until the higher rpm's are reached.
I can hear a rattling sound in the turbo at idle it seems to go away when rpm's go up.
Took it to repair shop, they said turbo is bad, needs to be replaced. I started an online search/diagnosis of my own and think they may be wrong.
Here's what I think it could be:
1. boost leak - a leaking hose somewhere (tennis ball test?)
2. a bad wastegate actuator - I think this can be replaced, don't know where to buy.
3. a bad DV - how to check?
4. a bad N75 - how to check?
I'm trying to avoid buying a new turbo as money is tight right now, any ideas would be greatly appreciated!
