Thanks Mark,
Mine is in at the moment for a coolant leak, (came with vehicle at purchase) with local dealer, seems to be leaking from the coolant return line, already replaced that pipe and hose, issue identified by Brisbane euro independent a couple of weeks ago,
pipe - 7P6 121 065 Q
hose - 7P6 121 051 D
seems not to leak when everything is at op temps but leaks when engine and coolant is cold, because of that my suspicion is if it is leaking from the parts mentioned that it's a connector problem as they reused the old clamps, that's what they are doing in the morning replacing the 3 clamps with new Ottingers and having a good look around with a cool engine in the morning, if this doesn't fix the problem then all bets are off and so am I.
Let me know you thoughts please....

Update,

The items shown above have been replaced but unfortunately the leak persists and now has been identified as definitely as a leaking water pump (thanks for confirmation, Drag).
So my CKDA is going into local VW dealer next week for a WP replacement, dealer quoted $1640 includes $640 for 4hrs of labour.

My vehicle is still under used car warranty so after some negotiation I managed to get the selling dealer (a Sydney Toyota dealer) to agree to cover the full cost of replacement however my local VW dealer will actually be doing the work.
I know it's hard to believe but good onya Toyota!

I'm very happy with result as it saves me an 800km round trip for me, not to mention if there are any warranty issues post replacement the VW dealer is only 40kms away.

The video is no longer available, is there any way i can get this please?

 

V8 TDI CKDA engine water pump failure is a usual failure. Pump driving shaft gasket is the failure. On my Treg, it started by a slow leak, say one dashboard light every month, need to refill with coolant. Then it became to light every week, then I saw cooland on my garage floor every day and decided to repair. Access is a mess, you have to dismantle all vehicle front end.

 

Yeah lm not looking forward to replacing the water pump when the time comes , lm doing a coolant change soon it’ll be interesting to see if this has an effect on the pump

 

Ive been trying with local VW dealer to get parts and also enquired to an aftermarket supplier (BWA) but had no luck in securing a pump. Has anyone got a suggestion where in Australia i can buy a pump, O-rings and copper washers to do this job?

 

Hey Dragline (and others)
ordered parts by part number in other post, my parts have just arrive but coolant pump is just the pump itself (circled below)

is not the full assembly shown in your pics above,
question is,
Is it just the pump (and seals) that fail? and needs replacement?
or should i be sourcing other parts (housing ect I read somewhere vacuum ???) as shown in your pics

thanks
Jase
