Might be completely different thing but thought i'd mention it. The traction control light and ABS light stayed on in my golf gttdi due to a dead abs sensor.
Does your abs and traction control still work? as they bothed stopped working on the golf.
mines on and off , my codes were saying a wheel speed sensor and/or wiring loom part
changed speed sensor @£50 still doing it intermittently
abs and tcs is on mine
i had this happen to me around 6-7 months ago. it randomly turned on in the wet and stayed on.
all i did was disconnect the battery for 30mins, then reconnected it and hey presto, it disappeared.
Right i have a traction control light and engine managmant light permanantly on! plugged in a hand held diagnostics machine and it say its the maf sensor! car still seems to be running fine,dont want to buy a maf at 55 pounds which is non returnable if this isnt the problem!
what would you do?
