Hi all. Reading with interest your posts regarding "ACC not Available". Having suffered NO damage to the front bumper (not even the slightest scratch), my car threw up this fault 6 weeks ago. I would not reset by switching off and restarting. Took it to the dealer. They diagnosed radar out of alignment. They found no damage, so realigned it and recalibrated it. Cost £432.00! Ouch! So yesterday whilst driving home the fault appeared again, again no apparent reason. I only washed the car 3 days ago so there is no dirt or flies on the radar cover. Initially the dealer said 2 weeks for a booking but when I explained this is the second time in around 6 weeks and only 1028 miles of driving, they found an appointment for me this Friday. I will post here the result of that visit. Any advice from you guys before I visit them?
