Re: 2004 A4 1.8T Lacking power and smoking.
I can hear some dull "rattling sound" - seems to be coming from the top right side of the car - sounds like "loose fitting" ? It happens when I am driving on "uneven roads" - anyone has similar experience?
Please advise!
Thanks!

Codes are Boost pressure not sufficient, Cat below threshold and n75 open. Ran a readiness test and the following failed; egr system, 02 sensor, ac, catelyst.. time to trade in?

Yes, the OIL light has come on, there is oil I change it regularly, I highly suspect the cat converter. Expensive part to eliminate
