There is a black plastic cover at front of engine think clip on either side then lifts out to see belt. Did get mine done £460 including water pump and coolant flush.
Thanks Steve, belt does have Audi stamped on left of writing you can see, I was more worried about little cracks in third photo, any idea of replacement costs?
Bought 2012 A4 2.0 Tdi Tecknik se 2 months ago and at 72000 miles and was told timing belt has been replaced but no proof in service book but has been serviced every year, on 72000 mile now and Independant garage that has serviced it for years can't help as was on private plate then. Can anyone tell from photos if ok or needs doing? Pics added
