BOOST Problem: Please Help

**YardieAudiA4** · 10-12-2008 12:11 PM

Sup Zine Community,

Ive got an 01 A4 1.8tqm with neuspeed exhaust k&n filter and MTM Stage 2 Chip. As of late I have been unable to boost past 7 psi when driving. I've noticed that my vacuum lines are pretty darn freyed and worn so I changed them all and ensured that they are not leaking. When i floor it I can here a shhhh sound and again I cant get past 7 psi and typically i can get 13-15 psi. Any ideas?

Thanks in advance,
Oteni

it could be possible that the plastic endtanks on the stock side mount intercooler aren't holding up to the increase in pressure.

To ensure you are leaking pressurised air it to do a boost leak test. It is not just the lines which can cause boost leaks. That shhhhhh sound sure enough sounds as if you are describing a boost leak.

Well, Ive done a boost leak test and I'm leaking air in my oil dip stick??? When im charging the system i hear hissing in the dip stick and dip stick holder and when i lift the dip stick it goes pssh and releases the charging air. This is the only place I'm leaking air..Any ideas on whats wrong??

Thanks

limp mode, clear any CEL's (if they reappear, search and post them in this thread). check your dv? You sure you got all the hoses? are they all on properly and in the right place?
