Good evening all I was wondering if anyone knows where the 109 relay location is on a 2000 a3 tdi?
We have had a nightmare with the car cutting out over the last few Months. The car has been to 3 different garages, who have diagnosed various different problems, yet the car is still cutting out despite them charging nearly £500 to fix the issue.

 

Get on the Audi forums or p.m. Ali B on here ....

 

on my mate's A8, there was water ingress under the drivers door near the sill at some of electrical juncton, cable from boot mounted battery to engine bay. Use Audi forums

 

Also worth checking main wiring near battery. Remove connections to large fuses, clean and reseat.

 

Cheers. I've joined a couple of Audi forums. Unfortunately they seem deserted.
