Getting knocks even at idle! Can anyone help?

Discussion in 'A4/S4 forum(B5 Chassis)' started by imported_RastaS4, Aug 11, 2004.

  1. My car has gone through all RS4 conversions. But for some reason, there is a knock happening. I truly felt it after my last modification (Camshaft + Air Box + Y pipes + ECU) from 390 Bhp to 460 Bhp. I tried changing cams to the older ones, tried changing the air flow sensor, checked the K04 Turbos, checked my exhaust system, checked my dump valves, etc... but still having the same problem. I also put it on the scanner and there are no fault codes! Can anyone please give me some ideas as to why am I having knocks in my car? (By the way, obviously the power decreases tremendously when a car starts knocking) /ubbthreads/images/graemlins/confused.gif

  3. Is it possible that I might see (on graphs) or feel knocks because my knock sensors are going haywire???? Meaning that: could my car not actually knocking but because the knock sensors are defaulting knocks are occuring? /ubbthreads/images/graemlins/confused.gif
