I have a 2019 Octavia with the 2.0L 150 CR diesel engine I've had for a few months. I've recently noticed a noise which seems to come from the cambelt side of the engine when the engine is relatively cold at idle (see video).  48K on the clock and well looked after.

 

Any ideas?

I'd start by removing the auxiliary belt to see if the noise goes away, after that your into the cambelt area. Does sound a bit like water pump to me.

Sounds a good idea. Thanks

This slow "worr, worr, worr" sound at right wheel is from oil-vacuum pump and it's absolutely normal.
More louder when cold, more silent when hot- but doesn't go away completely.
My '2016 TDI Octy sounds same since was new (now 160k km on clock) and my workmates' few new VW Crafters sounds the same.

There're some posts and YouTube videos about this too.
