Had an issue on Sunday where car started fine, I was doing some diagnostic work with ISTA/INPA and left it running while I was doing work as I haven't been driving the car much and was concerned about battery draining (could not plug in a power source). Got to a point where I needed to restart the car and when I went to start it back up, the car cranked and fired up but quickly stalled and seemed like the starter was still engaged until I hit the start/stop button.
Tried a couple more times and it would crank but not fire and same thing, sounded like starter was still engaged until I hit the button again.
I checked voltage and it was good, hooked up a jump pack just in case and same issue.
No CEL but checked codes and was getting 2AFE - DME: Voltage at Terminal 87 open circuit. I checked all fuses and made sure connector on top left of fuse box was fully seated, all seemed good. I jiggled the fuse box a little not expecting much and it started up no problem, turned it off and started it again, all good.
Went to take the car out yesterday and something similar happened though it seemed like it was trying to fire but the starter would still make that sound until I hit the button. Came back to it a little while later and it did the same thing. Connected jump pack again even though voltage was okay. Tried again and it started and didn't get the starter sound but was running a rough and eventually went into limp mode. It stalled shortly after. Checked codes and got a whole bunch:
27E7 DME: Limp-home operation, 100% el. fuel pump activation
2AFE DME: Voltage at terminal 87 Value below threshold
2B14 DME: Throttle-valve actuator initialisation
2B2A DME: Idle actuator, initialization
A125 CAS: incorrect or implausible signal from engine management
Car just had the positive battery cable recall done and when I went to pick it up the battery was dead, needed a jump at the dealership to start and the amp seems to be dead also (no audio - have another thread for that).
I'm going to try my AGM battery, have a LiPo battery in there now but I don't think its a battery issue as the voltage seemed okay and I also had the jump pack connected.
I've never had any starting issues like this and it just seems like too much of a coincidence that I had the positive cable recall done and now I'm having what seems like battery issues.
I reached out to the Service Advisor about the amp the day after I picked the car up and he was responsive at first but stopped responding, need to follow up but would like to hear opinions from the eperts on here.
Thanks for looking!
