Thought I'd just advise you of what happened to my GTI. It's nearly 3 years old with 30k on the clock and has been utterly fault-free throughout. However, the other evening I was just driving easily around town and the temp gauge went through the roof; the car entered limp mode capped to 4k rpm and engine and epc warning lights came on. The following day I took it to the dealer (it's still under warranty) and they couldn't look at it but the fault codes had cleared and temps were normal so I drove the short journey home. Temp went up again and fault ligths appeared so I suspected thermostat or waterpump fault.
To cut to the chase, took it in today and as suspected there's a waterpump failure, to be replaced under warranty. They're taking photos of the pump for me but VW Germany want the failed part back. However, it's a black plastic impeller that has detached from the metal drive shaft and hence wouldn't rotate properly. Iv'e asked what is different about the new part (to be fitted Monday) and await a reply, however I was clearly concerned that I'd receive an identical part with a design fault (imho).
Any thoughts on how I can go about obtaining as good a service and future proofing as possible really welcome. Thanks.

I thought vw had stopped using plastic impellers?

I'd have thought so...we'll see what the photos show although ideally I'd like to get my hands on it to better see the failure.

As Mcmaddy, said, thought this would have now been old news ? I remember this happening back with the MK5 Golf's (and indeed my 2005 MK5 GT TDI), that snapped it's impeller (under warranty) which was subsequently replaced with the "new" metal impeller version.
Guess that's as a result of cost cutting again ?

MK4's were famous for it
They were plastic, then became metal, then became plastic during the lifecycle of the MK4

It's not cost cutting, it's "weight saving". :whistle: :grin:

Its always the same. I remeber the amount of 1.8t having the plastic water pumps and when ordering parts asking for metal

I'm dismayed to hear the're still using plastic. I remember this on the MKIV but then you'd be replacing the water pump with each cam belt change.

Don't fancy having a metal pump fitted to my car :smiley: if a plastic one fails they just spin on the shaft a metal one tosses the belt

No belt on his motor it's driven from one of the balancer shafts by a chain i think.

Update: finally saw the pump...to my surprise it is electrical and was a burnt out motor with high resistance. I'm surprised. It piggy backs on a more usual water pump unit made largely from composite...the mech said they'd changed the design of this so the impeller is alloy now. If I get time I'll edit the video they produced and post it. Cheers.
