Drivetrain malfunction and 11A605 code.

[NocturnalMKV]

Hey everyone, I was wondering if anyone’s ran into this same issue before. I’ve tried searching but found limited information. I get a drivetrain malfunction sometimes during WOT on my E50 tune. Car goes into limp mode and power is reduced. I check the codes and get these codes. I’ve ran logs for my tuner and even after revisions, the issue persists. I thought it may have been due to an issue with the ethanol mix % but it’s happened anywhere between E45-55 according to my fuel-it ethanol analyzer. Car is currently FBO MHD tuned with XHP stage 3 and sport+ coded in.

First off, ditch Sport+, you have a tune, why fuck with an untested factory map that dicks with the throttle response.

Second, most of those codes aren't interesting, but you need a battery.

Do you have a log? It appears that you're running out of fuel. Who's your tuner?

I’m assuming you are seeing the fuel pressure drop in the logs?

Lol sport+ was coded before I was tuned and on jb4 only. Need to get it coded back out. And yes let me post some logs.

Fuel pressure seems fine based on my limited knowledge of reading logs. I’ll post some logs though.

Well, you're over-boosting like a mother fucker, which is pulling timing and closing the throttle. Get that cleaned up before you do anything else.

Fuel pressure is dropping a lot at the big end, worry about that after you get the overboost cleaned up. Log doesn't look great. Who's tuning this?

Like ZRK said, you are hitting 131072 which is torque/load target mismatch.

Thanks. I assume this is something the tuner should be able to fix with a revision?

Did you ever get this resolved? I'm currently having the same issue.
