A couple of weeks ago I noticed a rough idle on cold startup that went away when warmed up on my e86.
It doesn't get used much and sits on the drive for a couple of weeks at a time without being used.
Took it out this morning and got a CEL whilst it sounded to be misfiring (only got about 100M down the road).
Have scanned the fault codes and got 0029cf failure detection cylinder 5 along with 002E1A temperature transmission sensor.
It had an inspection II at BMW less than 1000 miles ago albeit in May.
Any thoughts? Surely not dirty spark plug as they should have been changed during the inspection II. Injector maybe?
