So, had an interesting and unfortunate evening today with my M5 Competition. Car is a 2019 M5 Competition, January 2019 Build Date, Took Delivery in late June. Car currently has 3200 miles on it. Mods are Remus Cat-Back Exhaust, and BMC filters inside of stock airbox, and charcoal filters are removed.
Leaving the gym, got in the car, hit the start button, fired up fine, pulled out and got on the road. Merged onto the interstate in heavy traffic. At this time the car was in Sport/Sport/Sport/S3, windows down, climate control off. Temp outside was 86 degrees F. Was inching along in traffic going just fine. Got hot in the car. Closed the windows, hit Max A/C. Soon after this, the engine started "fluttering" (best i can describe it). RPMs were quickly varying between 100-600 RPM. Gas pedal was basically non responsive. Engine then puttered and stopped, while I was in the far right lane on the highway in traffic. I immediately hit the start stop button to turn the car back on, it fired on, but immediately went back to the same state. Fortunately I was just coming up to an off-ramp off the highway, so took that to at least get the car off the highway. While puttering, the transmission was shifting super rough, and almost felt like it was slipping. Car was still putterring/fluttering, gas pedal was barely having any affect. Fortunately there is a Park and Ride off this exit, and the 2 lights (2 right turns towards the park and ride lot) were green. I was able to coast/lightly apply gas pedal and limp the car into the parking lot. From here, things get interesting. As soon as I park the car and it is stationary, the engine shuts off. At this point, there are no errors or anything displaying on either the dash or nav screen. Try to fire up the engine, starter goes, engine fires, then immediately shuts off. Try this again 5-7 more times, same thing, engine turns over then immediately shuts off. At this point i'm worried that either (a) I have bad gas in the tank, (b) if i try this more then ill flood the engine, (c) i'm going to drain the battery. So at this point I stop and use BMW Assist to call Roadside Assistance. Roadside Assistance answers and says the only thing they can see is a low battery message. I tell them that all the electronics in the car are working fine, I'm seeing no error messages, Check Control says "all systems ok", no CEL, but car won't start. The Master Techs had gone home for the evening, so only thing she could do was call a tow truck. Bummer. She arranges the two (60-90 minute wait) and hangs up with me. At this point car still isn't showing any sort of error codes and check control is green. I proceed to inspect the vehicle at this point to see if anything looks bad. No liquids underneath the car. Check the radiator, intercooler, oil coolers, and the notorious oil cooler on the front lip. Nothing is punctured, leaking, or broken that i can see. Check the rear for exhaust issues. Don't see anything. At this point I get out of the car, lock it, and wait 10-15 minutes for it to fully go to sleep (spend the time packing up my valuables into my gym bag from the car). Now it gets interesting..... Get back into the car after calling my wife to ask for a ride. Hit the start button, car fires up like normal, cold starts, settles in at its normal 800 rpm. Like nothing ever happened. Except this time, there is a CEL. I leave the car running and call BMW Roadside Assistance again hoping the car has sent them information on the CEL. No dice. On their side the car looks completely fine/normal. Check Control is still green. Hang up. Decide to see how the car reacts if I start driving it. So I take about 8-10 laps around the parking lot getting up to about 40 mph, and varying the revs, engine modes, and transmission modes. Car is totally normal. Try turning on max a/c, car works fine, drives fine. CEL is still on however. Called limeypride to discuss with him. He reminded me to make sure the tow truck was a flatbed and not a 2 wheel type. Really good point. Call and confirm it's a flatbed. Considered driving it home, but tow truck driver and BMW Assist both recommended not driving it for fear the same thing would happen again. Tow truck driver arrives and we strategize about how to get it on the flatbed without (a) having to winch it up and (b) without bottoming out the front lip. Tow truck driver was an absolute pro (Alpine Towing, seriously the best customer service I've ever had from anyone in the towing/car industry) and had wood boards to load the car without bottoming out the front lip. So now we go and start the car, starts up fine, just like normal, but NO MORE CEL! At this point i'm like all at the same time. Drive the car onto the flatbed, strap it down as not to damage my brand new wheels (which had literally just been put on the car 3 hours earlier). And off she goes on the flatbed. Arrive at dealer, start it up again to drive it off flatbed, starts up fine, no CEL, no erruor/warning messages, Check Control is Green. Car is currently at the dealer. Service will take it in at 7am tomorrow and let me know whats up. I'm a little bit scared to drive it at this point for fear of getting stranded with the same issue. I'm more worried that since the CEL turned off, the techs won't be able to see what the issue was. I'll keep everyone posted. Needless to say i'm not happy. EDIT: Update as of Thursday 8/1 - Dealer confirmed there was a DME fault code stored. Words they used were "weird DME fault". They escalated and were told it needed remote troubleshooting from BMWNA in New Jersey before a fix plan could be determined. They will keep the car at least a week EDIT- UPDATE 8/5: dealer is still awaiting action plan from BMWNA. I was able to get a description of the faults, but not the fault codes. turns out my car threw 3 different faults. 1. communication between both DME's 2. EWS -- engine start block 3. o2 sensor fault bank 2 pre cat. Anyone seen these? EDIT - UPDATE 8/16: Got note from dealer that car is complete and ready for pickup. Below are the notes from the tech. Note the multiple fault codes thrown and the troubleshooting procedure. Can confirm no parts were replaced. Notes edited for readability. Are there any BMW techs on here that can shed more light on these codes/procedure? 92377 ---1--- RECEIVED VEHICLE FROM TOW ZONE, VEHICLE STARTS AND DRIVES WITH NO SES LIGHT ON AT THIS TIME. HOOKED IN BATTERY CHARGER... ---2--- PERFORMED FAULT SURVEY, VARIOUS FAULTS STORED FOR DME AND DME2. TWO OXYGEN SENSOR FAULTS STORED FOR DME2, 12B001 12B204.

This post looks like it could use an “Index” and s “Bibliography” for all of its Citations. j/k Interesting dilemma...

Wanted to make sure to cover the whole ordeal, since (hopefully) most people haven't had to call BMW Assist, deal with flatbeds on this car, or had this issue

Very interesting and accurate description of the problem, not sure what could be wrong, an engine sensor or some other sensor faulty maybe, but intermittent and these are a real problem.
Keep us up to date with what the final outcome is, I like you would be nervous to drive far for fear of a replete.

UPDATE:
Dealer confirmed it is a DME Fault. whatever the code was is something they couldn't diagnose at the dealer. They have to involve the BMWNA folks in New Jersey. Will be without car 1 week minimum.

Sounds like possibly, a bad fuel pump control module. What was the ambient temperature outside?
I have had similar issues in my 750.

Well I sure hope your problem gets solved expeditiously. I’m very interested to hear what they do to fix the issue, too. Sounds like it could happen to anyone of us so unexpectedly.

From what the techs explain, the FPCM is overheating and causes the car to go into similar issues, you are experiencing. Fuel supply issues, drivetrain malfunctions, etc. It's really annoying! I get out of the car, and lock it with the remote, it goes into sleep mode after 5-10mins, and then it starts right up with no issues. Very similar to what you explained in your previous post. I don't know for sure, that's what causing your issue, but it does sound similar.

Will keep you posted on my DME issue. BMW NA is involved in my case as well.

Looks like they hit alt control and delete and rebooted it.
Good luck. I had a drive train malfunction warning. Car ran, just slowly. They did the same nonsense. Clear faults and it has been fine for the last 2000 miles. Wish you the same ! Enjoy it. |

Just kidding I couldn’t resist the metaphor. Kidding aside, I’m really hoping this doesn’t repeat itself in the future. It sounds like a major inconvenience and just a total PITA. Last edited by bradleyjs; 08-16-2019 at 04:23 AM.. Reason: Typo |

Seems a "hard reset" with power removed from the car did the trick, good luck and see how it goes.
