My 02 TD5 has developed some electrical issues, firstly, the reversing light and parking sensor sometimes come on when driving and stay on. Sometimes turning the engine off clears it, sometimes not. The wipers sometimes don't park themselves and I have to manually park them. When I'm towing, the indicators on the trailer stop when I brake and come on again when I come off the brakes.... is all this connected? I'm planning on taking it to the shop, but theres going to be a long wait for a space, wondered if this was an easy fix. Someone has suggested the ECU needs replacing... I have no idea. Cheers Sam
