Hi guys, the parking sensors stopped working on my audi s3 which has front and rear sensors I had the car scanned and it said it was the parking control module had a fault. I've took the parking control module out from the boot and was looking on ebay for one to replace it. Now does the number on the module have to match the replacement one? For example the one on mine reads 8PO 919 475 D however there is a second hand one on ebay with the number 8PO 919 475 J. If I'm correct this would be no good? I can't seem to find one on ebay with the matching part number so does this mean i need to go to audi direct and get one from them? If so how much am i looking to pay? Thanks in advance.
