Hey what's up guys idk what's wrong with my car at first I thought it was DME because i got ignition and injectors short circuit to ground and other DME codes Ill post a pic. Ended up getting it cloned and same thing it starts up fine once then struggles to turn on and gives me drivetrain malfunction or drivetrain but then goes away. I changed the alternator as well and even the fuel pump thinking it was that same thing disconnected the IBS same thing and even charged the battery same thing voltage I get is 14.6 around their when the car is on and 11.9-12.4 when only on ignition. Any ideas guys maybe something is keeping the car on only thing I haven't changed is the starter. ( Switched battery's as well forgot to mention that)

Did you check your ground cables?

There's a YouTube of a guy claiming that caused his slow start issues.

It seems more likely that it's just the starter, though, if you're using a new battery.

Yeah bro I scanned it as well with my friends scanner he has the ECS tuning one I forgot what it's called exactly I think it's the scwaben one and got the same codes as I got on bootmod3. Most of the codes go away but the DME relay ignition and injectors code always pops up also I forgot to mention I've also replaced the Intergrated supply module.

i think you tried most everything.
stop wasting time....and go to dealer with special instructions.

Book for 1 Hour Diagnostic and specially ask to speak to the Shop Foreman.
Instruct him on what you have done and the codes that you have seen.

ONLY Dealer has a Special IN-BETWEEN Harness/Computer that can connect in between ECU and Car.

They will or should be able to pin point the issue.
Stop replacing parts to no end.

These Cars with their Auto Start/Stops have a Really ROBUST Starter so chances of that are low.

This Diagnostic charge will or should be 1 hour.

I had an issue with my E90's ECU and they that is what they did to figure it out that 1 Resister in my DME Fried.
