2012 A7 Headlight and ACC Faults Help?

[markdjr]

I just got my VCDS cable and ran my first scan, I tried to use the Ross Tech wiki to track down the faults but wasn't able to find mine. Regarding the faults, the ACC has intermittently given me a fault while in use and shut off, then seemingly resets itself a few minutes later and I can resume use. The light fault comes up on the dash only sometimes, I had never seen it before flashing a stage 1 engine tune from EPL a couple days ago and since then the fault has appeared on the dash less than 50% of the time at startup, I don't know if it is coincidental or not. If someone is familiar with any of this I'd appreciate any feedback, thanks for any info.

first, I always try to reset all the error codes, and see what comes back. If they do come back then it's time to address them. Also, sometimes after flashing, you need to clear codes. if you are worried the errors are related to the EPL flash (maybe older software) you can always flash back to stock

As for the first code 03815, in 09- central electric, there's a TSB that addresses that code. Audi's answer is new software, and if it still produces the error, then replace the LED control module . https://static.nhtsa.gov/odi/tsbs/2014/MC-10122368-9999.pdf

As for the ACC stuff, sometimes another connected system doesn't work right (like the headlamps) and that messes up how the ACC works.

Sick! Thank you!

yeah, no problem, next time just google your error code with "audi error" , and usually helpful stuff pops up. good luck
