DCT E92 M3 Violent Jerking When Trying to Put in Drive

[SalM]

Hey guys, So I went to take my M3 out the other day, car ran and drove flawlessly. I have a 2012 E92 M3 DCT ZCP with 48k Miles.

So I got home parked the car, went to go out again about 45 min later, started the car and went to put it in reverse, and the car started jumping back and forth crazy aggressive, truthfully I was scared the trans was going to break. I quickly dropped it into neutral and it stopped. So Then I went to try putting the car into drive and same thing except this time was jerking violently forward.

Shut the car off locked it . Let it sit for 5 minutes and continued to drive flawlessly. I got the car GTS Flashed about a month and a half ago. I've owned the car for 3 months and the first month and a half the car was flawless never happened. Now after the GTS flash, its been happening here or there. I wanna say about 5 or 6 times in the past month and a half.

Anyone Have any thoughts ?

No limp mode or codes came up on the idrive or CEL light nothing. But I have a Schwaben Diagnostic tool from ECS Tuning and got these codes.

Codes:

CF28: Message Error (OBD Data Engine) from the engine control, receiver DKG/EGS, Transmitter DME-DDE/ACC

CF13: Message (Torque 1) Error. Receiver DKG, transmitter DME-DDE

CF1C: Message (Engine Data) error from engine control, receiver DKG/EGS, transmitter DME-DDE/DSC

CF15: Message (Torque 3) Error from engine control, receiver DKG/EGS transmitter DME-DDE/ACC

CF14: Message (Torque 2) error from engine control receiver DKG/EGS transmitter DME-DDE/CAS

All sorts of weird problems on various threads have been cured by this approach. Your battery may need replacing. Daytime running lights, Comfort access, Blue Tooth etc. all combine to give the OEM AGM battery a tough life. At Wide Open Throttle, the Alternator does not charge the battery.. to gain a few extra horses. If I had to guess I'd say the current draw (from a low battery) at start-up glitched a sensor or two such as the throttle position sensor and or something in the DCT ECU.. Just my two cents..

By glass mat, you mean the little clear bubble on the battery to show the battery life? Its funny you mention that because shortly after I purchased the car, I left the radio running for just a few minutes and showed low battery discharge or whatever. the car started no issues. But I will definitely look into that battery man. Thank you.

Anyone else have any other ideas ?

Mismatching software versions..

Car has stock engine tune?

Had the same issue with radio when a first bought mine. Turned out it was a bad cell in the battery. No problems since.

Flash to stock tune and see if it continues. Should not have those faults so I suspect an issue there.

I will be removing the flash and going back to stock DCT file first to see how that reacts.

What do I need to match up for both ? Is there a specific version I need to use?

RK tunes? Good luck then because that kid Jordan has caused nothing but endless problems for other M3 owners. I wouldn't bring my car back to him if I were you. Hands down worst customer service imaginable

Interesting. I've been using him for years on all my builds and couldn't be happier to be quite honest.

He doesn't have the fastest m3 for no reason; he's not an idiot. With that said I wouldn't let him touch my car if he paid me. I'm glad everything has worked out so far in your favor and I hope it continues. Another opinion can't hurt

who has the fastest m3????
jordan uses the same off the shelf files 99% of tuners out there use so it seams like you have a personal agenda here,ive had his tune on my car worked flawless used to switch back and fourth between rk and gintani when i was n/a

Last i checked he had the fastest f30/80 m3. No agenda, just the way things went with a few buddies of mine. It's possible he uses an off the shelf tune for the e9x, but he didn't for the e46/e39/335i. Maybe that's why he uses canned tunes now.

Update: Installed a new AGM battery from the dealership, and so far so good. Haven't had any issues or any hiccups so far ! Lets see if it continues

I'm not going to debate you on which car was fastest. You can Google it and see there was a thread about it and he posted the slip time. The reason I have a negative opinion of his work is because his lack to make the situation right after making a mistake. Tuners make mistakes all the time, they're humans. How they go about rectifying the situation sets them apart, in my opinion. Glad the op got it figured out. If you want to talk further pm me in a respectful way and keep the clutter off the boards. Cheers

Would a person who drives their M3 year round need a battery tender?

What is the recommended min storage duration that would require a battery tender?

Another symptom of the bad cell was the auto stop/start wouldn't work.

I bought this battery monitoring device that constantly let's me check my batt health via Bluetooth and a smartphone app. Gives me peace of mind.

Update: Been about 2 weeks. Nothing has happened, everything is going smooth as butter knock on woods. Will keep you guys posted !

[SalM]

Another update been about 3 and a half weeks and it hasnt happened once ! Hopefully the solution was a new battery !!

Unfortunately the jerking had just happened again and started jumping back and forth.
