High there, I am new to the forum and have a question for anyone who knows the answer. I have moved to the canary islands and have just bought a a4 avant 1.8t 150hp. The mot failed the other day on high emissions but here they have no garages that are reliable enough to trust to fix it. I took it to a vw audi garage the other day and they charged me 2,200 euros to replace the lower suspension arm and both front wheel bearings. So to take it to them to sort the emissions will cost more than the car is worth. I have been looking up and it could be the MAF or cat possibly. There is a place where i can get cheaper parts from here so if anyone knows what the possible cause of this could be it will be greatly appreciated if you could reply to my post.
