hi iv a 00 gt tdi golf 115 bhp, the otr night my dimmed head lights and fulls, plus wipers, plus heaters, plus intercaters just stopped working... iv cheacked the fuses, all ok.. i was also told that the clocks in the dash could be the problem seen as there apart of the ecu, so i then could only get 150 bhp clock so i got the ecu done to take to any clocks, aka:115, 130, 150.... but stil no improvement...
Check relay (usually marked 100) and is fitted to the relay plate on the offside under the dash (bit of trim removal required to gain access) possible water ingress through grommet in bulkhead.
