    Question A/C Quit and Start/Stop Fault

    Guest-only advertisement. Register or Log In now!
    Hi, all! Been a bit since I've posted...life gets in the way.

    On my way to work this morning, the A/C quit working. Blower works, but no cold air...compressor never kicks on.
    Also, I have a Start/Stop system fault on the dash. This might be the cause of the A/C issue, but don't know.

    I've turned the car off and on, to no avail...no A/C, same fault on dash.
    I don't have access to the ECU, so I can't see if there are any faults.

    Gonna try and get it into the shop today, but doubt that'll happen.

    In the mean time, anything I can look for to see what may have caused it? Something simple, like a fuse or the such?

    The saddest part, I'm at 37,700 miles, so if it's something major, I'm kinda SOL.

    Thanks!!

    Sounds like the car should still be under warranty. I would let the dealer figure it out.

    You're right, I checked, 4yr/50k. I thought it was 3/36k.

    It's going in Monday.
    Will it pass the computer check after I remove the EPL tune? That's the question.

    Update, for anyone interested...

    Got home on Friday after a MISERABLE drive home in D.C. traffic and the heat. Miserable, I tell ya! Grabbed the VCDS and pulled the faults. Only one of significance, at least in my ignorant mind was this:

    18062 - Coolant Pump 2
    P261A 00 [039] - Open circuit

    I didn't clear it, wanted all the faults to be present for the dealer.
    In preparation of the dealer trip, I flashed the ECU back to stock and took the car for a quick spin to make sure everything, except the obvious, was working.

    Well, guess what, A/C and Start/Stop WERE working. No clue how or why, but they were.

    When I got back home and decided to flash the EPL tunes and confirmed that all systems still worked.
    Cleared all the faults, took it for another spin, no faults returned. The trip might not have been long enough to cause the faults to return...I'll check them again when I get home from work today.

    So, not sure what happened, but I'm not overly concerned about it for now.
