Hi all, got a problem with an intermittent misfire and I'm hoping someone with more knowledge and experience than me can shed some light! The motor... 2005 A3 sportback 8PA 2.0 fsi (non-turbo) engine code BLR The situation... Had timing belt, water pump and full service (inc. fuel filter) done a month ago. Car ran beautifully (as it did before) for a week after, then started missing on cylinder 2 (from obd2 scan). Didn't happen often, was always between 2-3000 rpm but getting above 3000 would clear it. Replaced plug (even though was just done during service) and coil pack on cylinder 2. Didn't solve it and gradually started missing on 4 as well as 2 (again only every now and then). Took it to local garage (not vag) and they replaced the other 3 coil packs. They reckoned they had sorted it. Drove home, same issue, turned around and went back. They didn't know where to go from there (other than start fault finding with a blank cheque) and I had work comittments to return to so had no option but to do a long journey with the A3 doing as it pleased, sometimes missing like a *****, sometimes smooth driving. Was almost like it was getting stuck in it's misfire zone and then out of nowhere it would clear and be fine again. Anyway, made it and have avoided using much since, other than to fault find! Been through the vacuum lines, although I sometimes think I can hear a leak I cant find it with water / carb cleaner, so maybe it's the mind playing tricks! Went for a test the other day and she drove brilliantly for 20mins, then got stuck in misfire zone again! Codes are... P0300 random/multiple misfire P0302 misfire cylinder 2 P0304 misfire cylinder 4 Doesn't seem to matter if she's hot or cold, just does it when she wants, and doesn't when she doesn't! Sorry for the essay people, but thought the more info, the more chance one of you could help! I'm up in the mountains so vag com is a long way away! Thanks in advance all Done a lot of forum searching but not found the key or the secret yet, just hoping for sage advice before I bite the bullet and go a long way in search of vagcom!
