Hi all,

Bought a 2011 272ps DTI last week and it's got ACC issues... Basically neither ACC nor standard cruise will activate at all or throw any lights on the dash, just no response. I have an OBD eleven scanner which gives two faults; Adaptive cruise sensor - no signal C110B49 and Adaptive cruise sensor - misadjusted C110300. If I clear these fault with the OBDeleven app then. all get dash warning 'ACC and fwd assist unavail' but again they disappear next engine start. I also get Crtl module faulty B200000 which won't clear at all.

I suspect the control module is dead - I'd like to start by finding the control module, checking the fuses, connections etc, maybe opening up and checking for any blown components on the board. I ca't find any information anywhere as to where etc unit is even located! I've also probably got a calibration issue with one of the sensors but no idea which one. I guess I'll need to get VCDS...

Any ideas for any of the troubleshooting for this fault would be appreciated - I have spoken to a local coder and asked if he could code out the ACC function and leave me with just standard cruise but apparently this isn't something he's willing to do.

Cheers guys
