MY12 TDI Wagon Losing Coolant

[Amalgam]

Just got the Passat back from a different dealer, but with the same news.

They have pressure tested and the system passes They have topped up the coolant and continue to blame "evaporation" for the coolant loss and say that it is normal.

There is a slight rotational slack with the reservoir cap. About 1 degree. This was similar to that a new car in the showroom.

I would ask members to check their reservoir lids and report back if there is any rotational play and if it is related to any coolant loss.

Thanks

I've had to put a cooling system under pressure for a good 24 hours, before I found a weaping water pump.

Surely by now in your case, a tell-tale pink stain would be starting to develop.

Unfortunately during our last trip to Margaret River in February, I must have parked the car overnight near an ants nest. When we got home, the car was covered with hundreds of small black ants. It took 5 high pressure washes with the trusty Karcher, including the engine bay, to flush the last of the ants away.
