Read point 2 of my guide. THe warning light covers tail and stop lamps. THere are two tail lamps in each cluster, one is the second filament of the stop lamp, there is also a seperate 5W bulb. Check these. Also check the correct wattage is fitted as this can trigger the warning too. hello and thanks for your reply all brake lights are working fine.i read some where on here that the warning light could reset it self. and i also read a post about vagcom a lead to connect car to computer so i can reset warning light myself have you any knowledge on this lead
