P060C - Internal Control Module Main Processor Performance

[McNeil]

2017 Audi A6 Competition 63k
EPL Stg 1 ECU/TCU
RS7 Airbox
Plugs recently replaced with NGK 94460 Iridium - no gap change

Last night after a hard acceleration my car when into a limp mode of sorts and triggered the EPC light. The car would not accelerate/drive after this fault code, so I pulled over and restarted the car and the issue went away.

Most of the search results on the EPC light revolve around cylinder misfiring and changing the gap on the spark plugs.

I used my VCDS this morning and found 2 fault codes: Neither were misfire errors.

1. P060C - Internal Control Module Main Processor Performance
There isn't much specific to this code on the forums.

2. P0451 - EVAP System Pressure Sensor
This issue could potentially be the charcoal canister and was only intermittent.


Does anyone have experience with P060C?

Thanks!

Did you make any other changes with any apps or VCDS?
Is the tune recently applied?

No recent changes. Tune is 3 months old at this point with zero issues prior.

I just experienced something similar, around top of 3rd gear, WOT, the car threw all kinds of lights (EPC, big message saying Max Engine Speed 1500 RPM)
I could not accelerate at at, pulled over restarted and everything was completely fine. Ran it through multiple high RPM/redline gear changes again, no issue whatsoever. Ive been on this ECU/TCU tune for 3 months with zero issues, thats why im suspect of gas being a potential variable.

Only thing I can think of is my local gas station maybe changed up their E85 content? I usually manually test it once a month for the last 6 months and its dead on E85, perhaps this batch was E51?
I'm on 93 tune, so maybe it wasn't happy with my current mixing ratio E85/91. Will do some knock logging and see whats up, I typically have zero knock with about an E25-30 blend

Knock Logs are completely clean, E85 is 85% Ethanol still.

Ran 2, 1/4 mile pulls, absolutely normal

Chalk it up to computer error I suppose?

Did you check your PCV?

Could this be failing at 37k miles?
