Drivetrain Malfunction, Multiple Misfires, getting worse...
Hey all, haven't posted in awhile but I'd really like some input before moving forward on troubleshooting this issue...
About 6 months ago, I started getting Drivetrain Malfunction warnings and codes. Unfortunately I don't have the codes from those occurrences but I can assume they are the same as they are now. I did some general troubleshooting, ended up pulling off my JB and the problem went away. I'm pretty busy so I tossed the JB on the shelf and didn't think about it much until recently. I've again (without the JB installed) had the Drivetrain Malfunctions come up. This time I went ahead and got Rheingold set up and pulled the codes which tell me the following... - Combustion misfires, several cylinders: Fuel Injection is switched off - Combustion misfires, several cylinders: detected - Combustion misfire, cylinder 3: Fuel injection is switched off - Combustion misfire, cylinder 3: detected I've done quite a bit of reading and understand that the problem is likely one of the following... - Spark plugs - Coil packs - Injectors - Ionic control module (does the 2013 F10 M5 have this? I didn't see anything that looked like the part online looked like) To start the troubleshooting process, I swapped the coil from cyl 1 with the coil from cyl 3. I also went ahead and cleaned the air filters (K&N) and the MAF's... Since the problem is not being caused (just exacerbated) by the JB, I went ahead and reinstalled it... Took the car out again this morning and got the exact same codes and report for the same cyl 3 misfire. What confuses me is that it says misfire on several cylinders. Does that mean that only one was bad enough to pull fuel? Assuming that I got my cyl # correct, this would rule out the coil. When looking at the engine from the front of the car, I swapped the front right coil with the one just behind it on the same side. I understand the numbering starts from the front right at 1 then goes front left, back to the next one on the right and zig zags the rest of the way. Can someone confirm that? One thing that I haven't seen mentioned too much is battery. My battery is likely near its end of life and I saw one undervoltage code the last time I pulled codes (not today tho). May be completely unrelated however but thought it was worth mentioning... Does this point to anything specific for anyone? I would have checked my plugs but couldn't locate my plug socket... I'm outside of dealer warranty but have an aftermarket warranty. I love working on the car but only have so much time so will take it to the shop if need be... Thanks in advance for any help or advice! |

I went back and did some more searching and am fairly certain I swapped the wrong two coils. Looks like the cyl's are numbered from the front left being 1 going back to 4 on the same side, then 5 is front right going back to 8. I'll try swapping the real #3 and report back with findings...

That should do it. I had something very similar with out the mod. Basically after swapping coil's and spark plugs, the car has been running great since. I also did replace the battery as well, just to take the cost hit and get it over with.

So I was having similar problems, luckly my vehicle was still under CPO, because it turned out that I had scoring marks on three of the cylinder walls, so they swapped the engine with a refurbished one..... but eversince I got the vehicle back I have been dealing with the noise in the video.... have you guys experienced this ?

Drivetrain malfunction m5 f10 PLEASE HELP
I recently purchased a used M5 f10 2013 41k miles no warranty . Light acceleration triggered this and alot of smoke from tail pipes . After 5 mins parked engine off it went away . Checked code and it said cylinder 8 misfired . Changed all spark plugs and coil pack changed oil too . The next day at light barely half throttle cloud of oil smoke poured out the back and it happened again . Can anyone here help ? If its not the coil pack and spark plugs what could it be?

Perhaps chance a visit to a dealership to have them see if your problem might be one of those? I don't believe you have to be the original owner, it's for the vehicle. |

Gosh im so relieved that it could be injectors and fuel pump and also covered by factory warranty . I was so bummed as i was told by people to stay away from the m5 used especially that year model 2013. When that cloud of smoke came out i thought oh no there goes the engine ...
