First post here but just a quick warning to all about some LEDs I picked up off Ebay. These were guaranteed not cause CANBUS errors but created an absolute disaster. When I plugged in the new LED into the fronr park lamp socket, it upset the onboard CPU to the point where it wouldn't communicate with the transmission control module, leaving the DSG locked in P. My garage is an Audi specialist so they managed to reflash everything and get it going again. PM me if you're intending to buy some of these and I'll be happy to share the details of the vendor. Has anyone successfully installed LEDs? Who are the best vendors?
