Hi all, I decided to get under the car and noticed that just after the CAT there is a hole that is bunged up. Its a blueflame exhaust from the turbo.
When running the basic settings in vag com to test the rear 02 sensor (think it is 030 or something similar), the front one seems to be working showing 111 or 011, flicking between the two), but the rear is just showing 000 with a faint flick to a 1 for the first digit every now and then. This is making me think that it is not working properly. But after seeing this other hole, should it be going in there, on the cat?
Thanks in advance
