What goes wrong

The EA888 Gen3 1.8 TSI and 2.0 TSI petrol engines in the third generation Octavia (including the RS) have a known issue with coolant leaks from the plastic water pump and thermostat housing. VW Group issued a service bulletin covering leaks from these parts on EA888 Gen3 engines. Left alone the leak causes coolant loss and can lead to overheating. There is no recall; the fix is a replacement pump or housing with new seals.

What you would notice

Low coolant warning
Sweet coolant smell after a drive
Pink or white crust on the engine near the gearbox end
Coolant drips or puddles under the car
Temperature gauge rising

How to check it

Where to look. Rear of engine near the gearbox, under the intake

Check the coolant expansion tank level with the engine cold.
Look down the back of the engine at the gearbox end for pink crust or wet coolant, and look under the car for drips.
Ask whether the water pump or thermostat housing has been replaced and how often coolant is topped up.
If a workshop inspection is possible: pressure test the cooling system and scan for coolant flow codes such as P00B7.

Parts involved: Thermostat, Water pump.

What it costs to put right

≈A$830 to ≈A$1,660 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the water pump or thermostat housing been replaced, and when?”
“Do you have to top up the coolant?”
“Has the low coolant light ever come on?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car still has money owing on it, has been written off or reported stolen, what kms it showed in past sale ads, whether it has had accident repair claims and what it is worth today. That comes from the official records for that plate. Enter the plate and its state for the A$17.90 Vehicle Check, or the full history from A$24.99.
