Bought my first M5 two weeks ago -- 2013, stock. 70k miles. After a few miles of easy driving to familiarize myself with newfound power (coming from E92 M3), I hit M1 and floored it. Pulling hard in 3rd, I get the DT Mal and the car goes into limp mode. Something my M3 never did. I was very concerned that I had bought somebody else's problem, then I found this thread.

After a rest to compose herself, the car was running beautifully again. Put a new battery in as the original was still there and my dealer advised it was close to death.

Tried the same hard acceleration in sequential mode yesterday with the same DT Mal result. Waiting until my extended warranty kicks in before making an issue at the dealership.

But I have the sense that 10 out of 10 times I push the car the same, I'll get the DT Mal with limited power and limp mode.
