Scirocco Register

Just realised that the blue telltale light for the main beam no longer works in the mk2, mot is due soon so need to get this sorted pronto, already checked the obvious fuse but thats fine (and the main beams work) what is the likely cause?

Edit to add: having had another look it does actually illuminate its just very faint

I'm rubbish with electrics but it seems most problems seem to be solved by checking the earth connections to the dash and maybe the earth to the engine, the thin brown wire attached to the back of the engine on the rocker cover, seems to work for me.

I have checled the earths by the fusebox (had them play up on my mk1) and they are all fine nice and clean, guess it could be a faulty diode on the clocks or something, if i get a chance i may swap the clocks over for a spare set tomorrow to test that theory out

Swapped the clocks over for a spare set to test and using the spare set the telltail works perfectly so i shall assume the fault is somewhere on the printed circuit board of the clocks, anyone know if its possible to swap over the printed circuit boards without the need for soldering? looks to me as though it will involve soldering which i really dont want to take on but i will admit i wasnt brave enough to pull and see what happened for fear of damaging them, i dont want to use the spare clocks as the mileage on them is over twice that of the originals, could mount a seperate telltale i guess in the clock surround

Don't mess about with circuit boards. Probably just the LED itself has failed. Get another - just over a fiver from VW dealer. Or take the one out of your spare instrument panel. Installation is straightforward. Come back if you need help.

You can mount the speedo part of the old clocks into the new ones fairly easily.

Ben.

Easiest to replace the whole assembly.
