What fails
On these engines the water pump and thermostat are combined in one plastic housing. The housing warps with heat cycles and the seals start to leak, often slowly enough that you only notice the coolant level falling. It's common at moderate mileage.
Why fix it promptly
A slow leak becomes a fast one, and running a turbo engine low on coolant risks overheating, a warped head or a failed turbo. Leaking coolant can also drip onto other parts below the housing.
How we fix it
We pressure-test to confirm the source, replace the pump and thermostat housing assembly with the latest revision parts, refill with VW-specification coolant, and bleed the system properly. We'll also check the coolant pipes and hoses nearby, since they age at the same rate.

Common questions
Is a water pump leak covered by warranty?
Ask a VW dealer to check your VIN for any extended coverage or open campaigns first. If it isn't covered, we'll handle the repair.
Can I keep driving with a slow coolant leak?
Briefly, if you keep the level topped up with the correct coolant and watch the gauge. Get it fixed soon; these leaks get worse.
Will it happen again after replacement?
Updated parts are improved, but it's still plastic. Regular coolant checks catch any future leak early.
