I guess it's possible the water pump has a fault separately to my main faults, but even then I'd be surprised at only 20k miles
2016 T6 102, Stolen / Recovered. Charging Fault [Resolved]

So if no electronics, how would they decide the water pump needs replacing, especially considering their investigation was to do with glow plug wiring

No reason, I asked but the service desk could only tell me what was written down on the job sheet, and couldn't offer an explanation. Which is why I've told them I'll call back in the morning. Hopefully I can speak with the technician

How so?
Because they rarely have the staff capable of sorting jobs like this and never the inclination.

Not sure that makes any sense. They have access to VW technical, they are VW trained by the manufacturer, and time/money is their inclination.
VW specialists wouldn't look at it, they recommend main dealer. I couldn't resolve the fault myself, so what other choices are there?
Hey buddy , sorry yer not having much luck with your van .Honestly sounds like vw haven't been able to trace the fault but because your van is 4 years old then it's just flagging up that water pump and belts need done ,I would honestly look for a independent vw specialist and not go to vw directly especially if you are out of warranty ,just my opinion as from my experience independent garages have alot more knowledge than main dealers and are cheeper , it sounded like once you had sorted the charging issue with you van that the Glo plugs were getn sufficient power to work correctly and that fault had cleared , could be long shot as it's a different vehicle but my friends T5 battery was on its way out and he was having starting issues and turned out there was not enough power in the battery to heat the Glo plugs correctly , is the van still starting correctly and has the battery been tested ?

It's had a new battery, charging problem is now resolved, it's just the glow plug wiring fault that keeps coming up on the scan, and it takes a while to start on a cold morning.
Specialist said it would be cheaper in long run going to main dealer as they'd have to start replacing parts to eliminate potential faults whereas the main dealer should find the fault.
They can remove the ECU and bench test it, and if necessary re write it apparently. That's main dealer only.
Looking
I can't see the water pump replacement fixing your glow plug issue and regarding the egr flash I believe they ment flush possibley?. It honestly sounds like it's not getn enough voltage to heat glow plugs correctly as it says intermittent fault , ano you said you replaced the battery but did you code the new battery into vcds at the time you replaced ? Ano it's been working fine since you fixed the fuse but I believe the reason you have to code the new battery in is so the voltage regulator knows the amps in the new battery at the time of replacement ,am sure there is a few links to this on here , also just to check the battery is working correctly have you tried charging battery fully and then tried to start ?. When charging battery with battery wired up to van you have to also use a separate ground point for negative connection as the voltage regulator is connected to the negative terminal , I normally use the torq screws for headlight as a negitive point
Upgrading Starter Battery - how to guide
My van (April 2017 T28) is fitted with a Moll battery. I am experiencing some issues with it not starting after a few days sitting on the drive. Now this could be due to the tracker I have fitted draining it but I doubt it, I'll do some drain current tests before taking the plunge. If I were to...

Yeah, the battery is new from TPS, and I coded it using VCDS.
To be honest you have did more than what I would have attempted to do and probably did more problem solving than what vw would have did , looking back at the thread you said that you fitted a new battery and that went dead on way home obviously because you had a charge issue that you fixed so you no longer have that problem but is this the same battery you are using at the moment ? If so then if you haven't already I would fully charge the battery and reset fault codes then go through start procedure again and see what codes you get .just to rule out the the battery is not at fault ,a believe in yer logs it states that when yer glow plug faults were registered the voltage was around 11.7volts but not sure if that's when you are also cranking the engine over or if that is just the 2.5 secs glow plug heat up , be good if enyone can shed some light on if the voltage of 11.7 on the logs is sufficient
