I own a VW Golf TDI 1.6 Mk7 (2015) Odometer: 82,000KM. I would like to know at what Odometer reading should I change the timing belt/chain.
This information is typically found in the owners manual. That said, newer VW diesel engines like your EA288 use a 'lifetime' belt. According to VW it only needs to be replaced every 100-130K miles / 160-200K kilometers.
