I have a 99.5 manual Jetta and I think it has a boost leak somewhere.
Recently the turbo and timing belt were replaced by the dealer (no one competant I could find nearby). I did the intake cleaning within the last six monthes as well.
I took it the dealer for this problem and got an updated plastic lower pipe (the baffled one). It did not fix it and I'm not letting them throw more intake pipes at it.
I went over the car and checked all the clamp loaded connections on the pressurized side of the intake. It hisses like a badly leaking tire only when under load in gear, at idle it is not present. I've also noticed it seems to be smoking alot and I can leave a little cloud at will. I recently had it Upsoluted and EGR disabled via Vag-Com, also he set the injection timing which he said was too advanced to put the chip in. It's now set a tiny bit on the retarded side according to him. It was done mechanically not via Vag-Com. I can't find any obvious problems with any hoses and everything seems secure.
Does anyone ahve any advice on how I could troubleshoot this issue without spending lots of money on part after part? Also do you think it's possible that my intake manifold is leaking soemwhere from when I did the cleaning? It did not hiss right after I did that work but maybe after time something is loose?
I've searched boost leaks and IC piping already and have not found anything that can help me. Any advice would be greatly appreciated.
