As promised!
An update! Well today was the day.I took it to "get it sorted".
Result is...job done! Basically it needed a clean? The badge that is! Ive read online, that for sensors radar etc. to work properly, obviously a clear view is essential. My cars are never really that dirty anyway, I did though. of course, wash wipe clean the outside of the VW badge on the bonnet, behind which sits the radar sensor thingy.
It turns out? The inside of the badge needs to be cleaned too! It was news to me, (some on here may already know this).
I was sent a video of what was carried out etc, and the tolerances of the calibration etc....bit like rocket science to the dummy writing this report to be honest!
He said there are 2 calibrations? (or something like that!) one was withing tolerance, the other wasnt. He said for them to need re calibration, usually needs something to have happened to the car eg. lowering, bumps etc etc (as has been already suggested on here...many thanks all!),
End result was, the inside of the badge was cleaned. Put back through diagnostics etc. Then taken out for a test run, with laptop attached etc. to see all was well,(was shown the front assist in operation with the A.C.C all working fine)....Thankfully it was!
Oh, it also showed it needed a new battery for the key too! A few other minor historic faults, which were all cleared etc.
I was well happy, good price I thought too. I used a specialist VAG garage....was very impressed with them.
They gave me a printout of the "numbers"! etc of the front assist/ACC etc...As I say, it was all over my head! Im just well chuffed its all fine now!
Many thanks to all who gave me advice on this thread.
