F10 Drivetrain Malfunction Multiple Misfire
Hi All,
I'm looking for some advice with my F10 M5. It starts and idles fine, and even drives fine in low revs, but if you put your foot down hard, it hesitates for a second then starts to accelerate and as it gets to 3500rpm throws a drivetrain malfunction error on the dash. I've scanned it, and it came up with multiple cylinder misfire. I've changed all plugs and coils and after clearing all errors and driving it hard again, the issue is still there. Its using more oil than i'd expect it to as well although there's no oil leak. I've removed all air intakes and theres more oil in the passenger side (UK) intake to the turbo than the other side. The car sounds more throaty if that makes any sense, almost a flat 4 ish sound like a hole in the exhast but i can't find anything. The car will still reach speed, if you don't put your foot down all the way. I've cleaned all MAF sensors too and tried replacing, no luck. Short of changing all injectors, which i really don't want to have to do unless i need to, what would you look at next? Is there anything specific on these engines they're known for breaking which would cause this? The car is running new G25-660 turbos and remapped too, but it ran fine after the remap for a long time with no issues. Thanks all |

I had this same problem just a few weeks ago.
I use Carly and I also found a "Cylinder 2 Low Voltage". I replaced the spark plug, injector, etc and the problem was fixed. |

M5 misfire
Hi, my 2013 F10 M5 has an intermittent misfire. Luckily I have an extended warranty.
Its been to Ryebrook Worcester 5 times now. Its going back on 19th. What should you expect them to do in terms of obvious work and i will ensure that they've done those things. I know they have changed a coil and the ECU. I suspect they should change all coils and all plugs for starters? Thanks Max |
