Random misfires cylinder 1, 2 and 3
Posted by: dwang0725 (4468) on 2014-10-21 13:45:12	Share \| Report

I've always had very minor random misfires on cylinder 2 at idle as long as I've owned the car. Not enough to trigger the CEL unless I'm idling for more than 10 minutes, but I can see it on Vag-Com if i'm monitoring it. Now I've been getting random misfires on all 3 cylinders on the same bank. Plugs are OEM Bosch iridium (about 30k miles) and car is on original OEM coilpacks (108k miles on the clock). Does everyone think that since the misfires are occurring on the same bank, the culprit might be the POS modules? I have not swapped modules to verify, but if I do, and the cylinder misfires move to the other bank (4, 5 and 6) the POS module is bad? Why is it that I don't feel the misfires when the car is running and only at idle? WOT the car feels fine. Just wondering...

- I'd say give the modules a swap. That will give you a good idea. - Nogaro Nitwit 2014-10-21 14:17:38 (109 views)
  - Yeah. I'm contemplating on going over to 2.0t coilpacks. Let's see what answers swapping the POS - dwang0725 2014-10-22 15:11:59 (104 views)
- Run your VIN against the coil pack recall at your local dealership. - KBATTPO 2014-10-21 13:53:55 (100 views)
  - Coil packs check out. It was changed out when recalled. - dwang0725 2014-10-21 14:04:44 (90 views)
