Hello a quick question. I was changing steering module for adding cruise control option. For this option I need to change module to 8p0 953 549 F. Cruise control works fine. ABS and ESP too. But windshield washer control stopped working. So the right paddle works fine, but without working controls for windshield washers. What do you think? Where could be the problem? Car Audi A3 8P 2006.
