Rear lights

[Jason roberts]

Hi my left rear side light is saying it’s out on the dash when starting the car up or turning lights to side lights it comes in initially for 30 seconds then goes off changed bulbs but they both done the same could it be the plug that goes into the back of the light unit thanks

Hi most likely it needs renewing as that type of unit has steel tracks running along the back they supply power and earthing to the bulb holders and are prone to corrosion, there is not a lot you can do with the unit once its gone, try the connection plug you might get lucky.

Hi not really, remove the rear trim in the boot and its possibly two 10mm nuts holding it in, undo them and it pops out, you will find a more in depth video of the process on youtube.

Possible partially fractured wire/s in flexible harness from body to tailgate?

Kind regards,

Hi Gareth, the wiring for the light units runs inside the trim to the rear control unit in the boot and is nowhere near the loom for the tailgate which controls the rear wash/wipe HRW and fog lights on some models.

Is that right then Steve, on a 2007 A3?

Yep, there is no wiring for the lights running to the boot lid except for number plate lights and reciprocal power cables for the locking mechanism, from 2003 - 2010 they are all the same, please note the power and earth tracks as described. so replacing the unit at the back of the light is the most sensible option.

Apologies, wrongly thought in-tailgate lights.

Kind regards,
