Timing Belt Interval AFB/AKN Engine

Hello fellow enthusiasts,

Yes, I searched, but I didn't find anything.
Can anyone tell me at what mileage the timing belt should be replaced on an AFB/AKN engine?
what needs to be done and what the entire process would cost at VAG?

Every 120,000 km, the inspection including the timing belt replacement costs approximately 1300 euros.

Thank you for the quick response.
Perhaps you could also tell me when the AKN was first installed in the A4 model.

To be honest, I'm not entirely sure. I suspect that it was introduced with the facelift, so sometime around mid-1999, and became available for the A4.

Okay, the AFB was the first V6 variant starting in model year 98 (?), followed by the AKN in mid-1999 with Euro 3 emissions standards, and then various other engine codes were introduced.

Stefan.
