Misfire and Flashing EML
bacillus:
What make and type of plug are you presently using?
Tfsi_Mike:
I tried 1 step colder irridium and gave me a missfire ended up needing new coilpack, again :(
Be interested to hear what other plugs people are using.
Currently have a miss fire, plugs only been in 2000miles. Replacing all 4 coils next week, considering doing plugs again at the same time incase faulty coils damaging the Plug. Don't want to go round in circles with the fault

Well logged this morning and nothing though tonight it's definitely cylinder 2......
Not sure about spark plugs....though will be taking plug out this weekend on c2 so will tell you then.
xxx_mojo_xxx:
I had the same happen to my car about 4 weeks ago. Took it to the dealers and they said they could see the misfire but the fault guidance did not find an issue with any component.
So nothing has been done under warranty :sad1:...
In my opinion if it's happened once it will happen again, just a matter of time. I had my spark plugs changed back in Sept 2010. Since then I've done around 15K miles without issue... so my initial feeling is that its a coilpack on its way out.
Incidentally, the spark plugs fitted were Denso Iridium Power IK24 and the faults logged were:

Any ideas what I should try next?
I travel a fair bit and I don't really want to be stranded somewhere with an engine stuttering or running in "safe mode".
PeteM:
I've got exactly the same problem, reporting exactly the same in VCDS, multiple cylinder misfire and C2 misfire, have swapped coilpack and spark plugs which has made no difference, have the day off tomorrow so going to try to log some data to narrow it down.
