Service requirements 2015 tdi400 transporter and dsg question

[Transporter]

Pulled out the water pump on my second belt change (395k......I think) and it looked as good as the new one!

There are 2 types of water pumps now and for some time. Most likely, when VW specifies longer timing belt replacement intervals, there would be HD water pump used with appropriate bearing and axial seal to go the distance.

It's in a thread around here somewhere...........but a summary is (with only rough memory klms)
The engine light came on just after the warranty period and after reading up about it, thought I'd get around to it at some stage as it didn't affect the running of the vehicle. (sometime after 200k?).
Some time later, the flywheel started rattling..........I put up with that until it was almost undriveable and got VW to do that and the clutch......290k?
When they did that, they whacked the computer on it and at was coming up as EGR electrical malfunction.......the usual fault.
(their rough quote was $2800......if that's what it was!)
So after gathering all the info and help from the aforementioned video, I grabbed one from VW and did the job.
Took two goes on the computer to initialise it but it finally tested OK.
It did seem to have a bit less power but gave a smoother operation through the power band afterward.
