hey all im new to the audi world iv had my 2001 audi a4 quattro 2.8 ATQ for about a year now and iv recently had a rough idle and a flashing check engine light go off in my car and then eventuallt ended in a no start and just cranks spark and fuel are good ran the codes and it came out to a few different codes listed below

p0130 oxygen sensor circut bank 1 sensor 1
p0170 fuel trim bank1
p0173 fuel trim bank2
p0346 camchaft positioning sensor a circuit range/ performance bank 2
p0300 multiple misfire detected
p0304 cylinder 4 misfire
p0306 cylinder 6 misfire
p0305 cylinder 5 misfire


besides the o2 sensor all the other codes are new, engine shut off about 1 block after the check engine light started flashing then it wouldnt start again
any help with this matter would be appreciated thank you.

camshaft positioning sensor was replaced

 

If you've replaced the cam sensor, clear all the codes (they won't auto-clear), and see what comes back. Anything that does is still an issue. And all but the O2 code could easily be caused by a bad cam sensor.
