Hello Everyone
I have an 05 LIB GT Auto that is really suffering.
The main issue is it drives like a non turbo. Doesn't reach full boost until late 3k early 4k and once it hits 1 Bar it bounces back and forward from .5 Bar to 1 bar. Issue is more felt when car is under load, Driving up a hill or trying to overtake on motor way. The car jerks rather bad whilst acceleration. I have taken to a reputable "specialist" in Rhodes Sydney, Charged just over $500 in labour to diagnose and all they can tell me is because the car has 170k. Never heard so much rubbish in my life. Car is completely standard with full service history. No engine light and I have changed front O2 sensor with genuine item just in case. I have also had a good look around and not evident boost leaks.
Any ideas? Thank you in advance.
