Mk2 TT brake lights


New member
Hi guys,
might as well post here too

The right brake light, the outside bulb keeps going out
I've checked the bulbs twice and they are still fine and i just swapped one bulb with the other. They all light up and the right hand bulb goes out.

anyone have any idea how to go about fixing this?
could be alota things
bad connection somewhere, but id assume both lights are on the same circuit off the same relay ?
Ye I've just taken it out and the main power pin had a bit of black crap on it so I've given it a bit of a clean but now when I plug it in I don't think that globe turns on at all. I suppose I'll just keep cleaning and trying

Well that's what I'm thinking but where do you begin. What I don't understand is why they all light up and then the outer brake light goes out
this is caused by the earth pin
taking too much electrical load, due to a bizarre design flaw.
either replace the entire light cluster if the damage is too severe. otherwise,
there’s a DIY write up on the ttuk forum on how to wire anadditional grounding wire or something. I just got my workshop to do it as theyhave done this fix before

Ye I found a pretty good 8min video from some guy in the UK.
looks fairly straight forward, might head down to jaycar tomorrow and pick up some pieces to make the extra grounding cable
its a prick of a thing, did you do both your brake lights junn?
Yeap, though they both died at different times. It is veryannoying, but if you have a reliable VAG workshop, they should be able to fixit in under 30 minutes
How’s your TT going? Any mods recently?

I've done one so far and all is good
the cars going good. The headlights are really starting to annoy me. They're just not bright enough. Just bought some led globes so I'm going to give them a go
other then that the only recent mods are R8 ignition colis and DV+ diverter valve
still in the market for an intake and maybe catback
how's yours going?
Easy fix is take the light cluster out , then find the earth track and put a wire to the chassis thus creating a new earth circuit.
