Hi all just wondering if any of you know what type of tool and size I need to open this nut ..is it a specialised one I can only get with audi them selves..I'm trying to do an oil change on my a7 but can't open these ones?
I attached a picture below maybe someone has had this same question and know the answer
Hey I have the same issue I just got my ecu fixed and now this sensor is on dash and I believe it needs the new sensor, is it safe to drive the car until I get it into mechanic to get it fixed?
