Hey everyone. I'm having some issues with my turbo set-up. First off, I cant figure out what is wrong with it. When I start the car in the morning, it holds boost, but still dosent reach the setting that is set on the AVC-R. Its set at .70 bar. Then, if i run it hard 4-5 times, it stops holding boost all together. Now i cant seem to figure out what the cause of the problem might be. Is it a leaky wastegate? or is something wrong with the avc-r valve, is it because its heating up and not functioning right? Dezod help me out man, becauase all replacement parts will be ordered through u. I want it to run right, but theres lots of reasons why it might not be holding it. But i cant figure out why it holds only up .55-57 when it does hold. can anyone tell me where i need to start looking for leaks and what not.

do you have a boost gauge? what does the gauge tell you. my guess is that the wastegate spring is bad and you should get a new one probably. .7 bar isnt that like almost 9-10 psi? seems pretty high for a stock motor[im guessing your stock] i would turn that down a little bit. i dont know much about turbos, i just got mine, just my 2 cents

If it has something to do with heat then, rubber couplers and chargepipe connections mostlikely giving troubles.
Also, the wastegate deniately needs to be checked as well.

Whats the WG spring?
1/2 a bar is about 8 lbs, which seems to be a reasonably common WG spring size. The BC may not be bleeding off any pressure.
If it stops holding boost completely, definitely look closely at the WG, its likely popping open or the heat is causing it not to seal.
