Post by: mr mk2 on 21 January 2011, 13:52

my mk2 gti has failed its m.o.t. on its headlights, is says on the failure sheet faulty switch because when u put the side lights on the dipped beem comes on at the same time without moving the switch into its final position, ive changed the switch and the light relay but the problem is still there.  please has any1 got an idea what it could be and how to fix it as electics isnt my thing.

this is normal for dipped beam to come on dim with the sidelights on mk2s, and lots of other cars too! although, have you fitted a hid or relayed lighting loom? if so this will incorrectly bring the dipped beam on full brightness. in this case its an easy fix, look in the engine bay near the driver side headlight. down on the chassis leg is a ceramic coil thing about the size of a packet of polos with a yellow wire out of each end./ follow the wiring back from that to a 2 pin plug and disconnect it. then bin the coil :)

this is the dim dip resistor, which isn't required by law or the mot. they are prone to the wires rubbing thru onto the chassis leg and shorting out, which then sets fire to the headlight loom as its not fused!

though once removed you better check the sidelights still work before putting it back in for the mot ;)
