Thanks again for all the replies!

 

If the replacement cost was £150 ish I'd get it replaced for peace of mind but £500 for something that isn't showing any signs of issues as yet is a lot! It's just the car having 100k miles on it now.

 

For all I know it could last another 30k+ miles and for me that's about 6 years worth of driving. If it ain't broke don't fix it potentially?

Exactly, if it ain't broke don't fix it, it may last 6000 miles, it may last 100,000 miles, it may already of been changed. mine's original but done well to get to 61,000 miles.

Thanks everyone,

 

So yeah I have a timing chain so cambelt change isn't a thing. I have the latest revision too so hopefully won't need that looking at anytime soon.

 

I'm not under any sort of warranty unless something actually fails and that runs out in April. It's a second hand car with 6 months warranty.

 

With that said is it something I should look to get changed sooner rather than later and what's the rough price if this job? £400-£500 is a worrying amount if just a water pump change to be honest!

Wait until it starts to leak... as it will eventually do.

 

i've had 2x waterpumps and housings on my TSI.  

The first failed at the waterpump seal at around 90,000km.  It cost around AUD1300 including pump and housing.  I'm told parts alone were around AUD700.

 

The 2nd failed at 170,000km.  The housing cracked.  It was Christmas so I had time off and bought a cheap pump and housing from China for AUD150.  Used YouTube and some forum guides to change the water pump, decoke the inlet ports and change the oil/filter at the same time.  I probably spent 18 hours on it but 8 of those were doing the decoke and I was working fairly slow. 

 

All up it cost me ~AUD300 for parts, coolant, caustic-free oven cleaner & other solvents, oil & filter.

 

It's not a technically difficult job and the tool requirements weren't unusual.  If I was just doing the water pump again, I think it would take 2-3 hours to dismantle and 4-5 hrs re-assemble.

 

Top Tip:  Use a torque wrench to tighten the water pump housing bolts.  They are about 7Nm (IIRC ) and much more than that WILL crack the housing.

This is a great read - I have a coolant loss issue on my TSI VRS octavia currently dripping off a bolt on the back of the oil sump and traced it up to the middle of the front of the engine block, coolant around 2 bolt heads, mine has done 145k miles and still original pump, I can only assume my pump seal is gone, it's going max to min in about 3 weeks and 500 miles of driving.
