    2013, Audi A3 - ACC: unavailable

    Hi Guys, New here but have been stalking for some years ... what a great tool ! A good enough reason not stray from VAG I would say This is not your everyday fault and so am hoping someone out there can throw some light...

    The issue here is that I have an adaptive cruise problem and showing the 'ACC: unavailable' message. I have done the common sense stuff such as cleaning the sensor lens surface and removing/reconnecting the plug with some wishful thinking switch cleaner. The cable and harness around all look in great condition. I use the function on a daily basis and know that one day it was working and the next day woke up and it was not - no knocks or possibility of accidental damage - The sensor is all secure and mounted solid.
    Getting connected - [13] Distance control module reports as below. With ignition on, engine not running the faults clear. As soon as the engine is running the faults appear.
    Now I have got a used replacement sensor with identical part number but from a 2013 Golf which I recoded - 00200301FE0309 as per the Audi one here. But realised it's a bumper off job to fit it so want to cover the bases as far as possible before getting int that. Also a component protection fault appeared as a new fault after coding the replacement. I wasn't sure what to expect with it not being installed in the correct position and not being driven a short way to clear any other faults? Any adaptation required? It would be great to get a steer with this.
    I should also point out that the 'Unknown Error Elaboration error' was not showing before I showed the car the replacement sensor -

    Dealer job to remove CP.

    What comes to original ACC module. Faulty module?

    This is not a 2012 car. It's clearly a 2013:
    WAUZZZ8VXDA0xxxxx

    I've adjusted the thread topic to reflect that.

    Looks like the old ACC sensor in the scan above has failed.

    I agree with downtime; CP removal is a dealer job (or at least someone with factory ODIS software and access to the factory servers) and then the replacement sensor needs to be calibrated, which requires special targets and measurement gear. So it's not a DYI project.

    Thanks downtime - The scan in the post is from the original module. But before seeing the replacement module there was just 1117 - Automatic Distance Control - B10E7 F0 [040] - Disconnected - The fault clears with engine not running but come on immediately after engine starts.

    Thanks Uwe, Well the date of first registration is 26/11/2012 - So clearly made before 2013 - The MY is 2013 ...It's just one of the early ones I guess. I'll remember to be clearer next time to avoid the confusion.
    I'll update about the CP removal for those interested.

    Model year is what matters when it comes to diagnostic info. I saw a mention of Component Protection and was like, "What, a 2012 A3 doesn't have that!"

    FYI my previous Audi was built in JUNE 2006, but the VIN stated it was a 2007 model - the MY changeover happens in mid year around the time of the factory summer break.

    Update on this one. All sorted. My local independent - Quattro-Tech removed 'component protection' at a very reasonable price which includes an on-line check that the part now fitted was not from a stolen vehicle. The used sensor was from a Golf 7 on the same MQB platform so no real surprise no alignment was required as I mounted it with the adjusting bracket it came with untouched. For interest I found this DIY aligning routine and wondered if anyone had given it a shot? ...https://www.audi4ever.com/blog/eintrag/25254-blog/
