Hi .

Can anyone tell me where the Auxiliary water pump is located on a 2018 Fabia petrol 1.0 TSi please? I've got an Fault code on OBD 11 P2B6300 telling me there is a problem with the Auxiliary water pump. I want to check the connections and replace the pump if necessary, but don't actually know where it is!

Thanks in advance.

P2B63 on the VAG stuff is "coolant pump 2, blocked" and it's often logged as sporadic. On the 1.0 TSI (EA211) pump 2 is the little electric charge air cooling pump (V188), not the main water pump. It runs a separate low-temperature circuit through the intercooler that's built into the inlet manifold and the turbo, and the ECU runs it in short bursts, including for a few minutes after you switch off, so you sometimes hear it whirring after shutdown.

It sits at the front of the engine, low down under the inlet manifold on the oil separator housing. Best access is from underneath with the undertray off.

Before buying one:

1. Clear the code and see how quickly it comes back. If it's sporadic and only now and then it can be the plug rather than the pump, so check the connector for green pins or a broken latch.

2. Listen for it running after a drive with the bonnet up. Silent every time points to the pump or its feed.

3. Check the coolant level and look for any leak around the pump and its hoses. Air in that circuit can make the pump labour and log as blocked.

If it is the pump, it's one connector, two hose clips and a bolt. Clamp both hoses first. The catch is the circuit has to be bled properly afterwards, either with a vacuum filler or the guided bleed function on a decent diagnostic tool, otherwise it'll throw the code again.

Part numbers for that pump are in the 04L 965 567 family with different suffixes, so check against your VIN before ordering rather than going off the engine code alone.
