For anyone looking at this thread in the future. I have a 2015 euro6 2.0 tdi SE L Octavia. I bought the car in April this year on 63k and planned on getting the cambelt and water pump done at 80k miles latest just to be safe. Wanted to do it after the 3 month warranty ended but had to get the alloys refurbished due to losing 3-6 psi a day and warranty doesn’t cover alloys apparently.
My coolant low level light came on a few weeks ago. I topped it up and it happened again two days later. Have a mechanic in the family so took it to his branch. The cars now on 69k and the water pump pulleys bearings had all worn away meaning the the pulley was oscillating when spinning and the cambelt was rubbing against the side of the engine and on the verge of snapping. I got told I was a very lucky boy having just bought the car. Just had them both replaced but I think people should air on the side of caution and get it looked at especially if you depend on it for work like me. Got a colleague with 69plate and he’s getting his done sooner than planned having heard about mine but he’s only on 63k.
