Timing belt DAYCO or OEM Audi

For my A3 8V 2.0TDI I paid 575€ to change the timing belt + water pump in Portugal.

Those cracks look worse than what mine did. I had gotten my car at 134k mileage and I changed my belt at 180k but to be very honest I think my belt had been on there for much longer before I owned that vehicle and I think I got lucky it never snapped into pieces.

Dayco, continental should be fine, as long as it’s not China Amazon stuff. Gates it usually good but as with anything these days quality control is a crap shoot.

Dayco is an OE manufacture for many manufacturers, it's a pretty solid belt. Quick answer is yes you should get it changed ASAP, I've seen a lot worse belts than this one and they drove to the dealership just fine.

I bought my timing belt/water pump off amazon. It’s a Dayco product (part number WP215K1B) and so far I’m happy with it. Obviously I won’t know if it’s some trash until a little further down the road, but I’m 20k miles into it and so far no trouble.

An old Audi belt motor goes 240k and the belt is still holding. I had a 2013 A4 2.0 that stretched the ~~belt~~ chain* at 70k and the valves kissed the pistons.

My last car was an A4 with AMB engine and the recommended timing belt change interval according to maintenance booklet was at 110K, while at the local dealer they were trying to persuade everyone to change it at 80K. I did one myself at 104K and it was just the right time as I noticed it started to stretch.

I changed my timing belt a month ago and my car had 111250Km and ten years young. First of all, I was amazed by the quality of the old timing belt, it was solid with no cracks at all.

6 years or 75,000 miles is the most I'd push any timing belt. We inspected a timing belt on a 2002 A4 with 57,000 miles in September - in-service date of 6/1/02 so it's over 6 years. Told her the belt is walking off, riding the edge of the tensioner and fraying.

After just snapping one in my Audi A4 B7, I had to rebuild that entire head. Total pain in the ass. The factory belt lasted 15 years, 175k miles before it let go.
