2001 Audi A4 Quattro 2.8 V6

Hi! I'm new to posting in the forum though I've been reading up for a while now. I bought a used Audi about a year and a half ago (big mistake)... while I adore my little Audibot, she's nothing but a pain in the @ss.

Replaced the coil pack, wires, plugs, valve cover seals (still leaking oil slowly), cats and flex pipes.... now she's misfiring again as of say 15 minutes ago. Mind you, she had been driving just fine an hour ago.

codes present:

p0030
p0130
p0352
p0304
p0302


Please, if you can give me any insight I would greatly appreciate it. I'm going crazy here!

 

p0030 - R 02 sensor
p0130 - O2 Sensor Circ.,Bank1-Sensor1 Malfunction
p0352 - Ignition Coil (B) Cyl.2 Prim./Sec. Circ Malfunction
p0304 - Cyl.4 Misfire Detected
p0302 - Cyl.2 Misfire Detected

 

i know a faulty o2 sensor wont cause a flashing ce light/misfire... but i have a brand new coil pack, wires, and spark plugs. it could also be the egr or fuel filter thats causing the codes (according to a website i was looking it up on). is this correct?

 

O2 will cause misfires............

However I think your coil is bad also. The circuit malfunction is what leads me to believe that.

When my O2 was bad I had misfires on 3 cylinders and now I have 0 codes.

 

Just cause you bought a new coil, that may have fixed a symptom, not the actual problem and that problem caused another coilpack to blow...get your 02 sensors fixed and see where you are at.
