I've searched - honest - and can't find what I'm looking for, which is:

2015 2.0 TDI Scout (CRMB engine):

A list of (SKF/INA/Dayco) cambelt full kit part numbers.

A guide on changing the cambelt.

 

I've done loads of cambelts over the years, including at least half a dozen of the old PD engines - but it's never a bad idea to take note of the wrinkles someone else has ironed out.

It has all come about because it's been little used this last two years and the first time it was started after a long period of being idle (apart from a failed battery - another story) it had developed a bit of a squeak.  Chased it down to the auxiliary belt area and just the faintest hint of metal filings round the bottom pulley.  I figured at 60K miles, 7 years and irregular usage, I might as well do the lot, especially the cambelt and water pump.

Sourcing a bottom pulley, possibly the belt tensioner, is another part of the job.

 

If anyone can fill the gaps, I'd be grateful.

Engine manual with everything you need to know, just used to strip and replace my 184 CUPA cylinder head, including cambelt and waterpump replacement;

OEM part numbers and diagrams, a quick Google will give you pattern/alternative part numbers;
