F82 Electrical headache (please help!)
Hi everyone , I got a real problem with my 2016 M4 F82.
Please, help! It started 4 months ago. And I’m still not able to fix it. I’ve tried 7 different car services , scanned the car for 1000 times, lots of same errors everytime, BUT, initially everything is ok with the car… A few words: It all started 4 months ago, while I was driving 80mph. The check engine lamp flashed and the engine power just dropped for 2 seconds and then everything was ok again… Day after day, week after a week the same happened more and more often. Then the «drive error” added to the check engine lamp. Again for 2 seconds and then everything disappeared.. 2 weeks later I got full pack of errors , including stabilization error, transmission error, road assistant error.. the engine shuts off for 2 seconds and then again, no errors ,nothing. Just disappeared.. Firstly I thought that it happens on any speed, just on a bumpy road. Then I noticed that it doesn’t depend on the “bumpy” road or any speed.. It happens while driving 5mph or 150mph… on any road ..no matter… Sometimes the engine shuts off and the gear falls to Neutral, sometimes it doesn’t. The car just looses the power, it’s like the fuel is being cut off.. but just for a second or 2… and then, again everything is ok.. What I’ve already done,checked and replaced: OEM The Battery- new LiOn. The Speedometr dash - new. Speed sensors- new. Checked DME block - ok. Checked BDC block (fem) - ok. Checked battery wiring in the trunk- ok Checked generator wiring on the engine - ok. The error codes that I have: 48002C IMC,ACC: DSC system interface; E06C43 DC9470 D8D401 D42C67 D35B3F D01557 D01558 D0156D D01570 D01B3F D01A08 D3542F And etc… Mostly all these errors are about wrong data exchange between ICM and DME. Still I have no idea what is going on… I have no strength anymore … ))) Anyone please help me… |

Why wouldn’t you load the stock tune, take it to a BMW dealer and pay for a professional diagnosis?
