I have the 2012 diesel 4x4 superb wagon that has had the water pump replaced and timing belt, due to the warning light coming on, and the coolant level down, this was done after a 800km trip. Everything was fine until we did the same 800km trip 5 weeks later. Same issues, Coolant  down. We checked the oil, no water in there, temperature was fine, both times. It’s going in to be checked over, but in the meantime is there any other reason it could be???

Leak from heater core inside car? Leak from egr cooler between engine and bevelbox? Last one is not a funny job to do. Need to take down the whole shebang on 4x4...but if you are handy and have tool required, shouldn't be overly bad. Of dealer have to do it, well hope you have savings to use. Its a 7 hour job plus parts, coolant, bolts etc. Probably 1500-2000 gbp.

Hopefully its just a bad water pump or sloppy job. That should be fixed free of charge. But you should be able to locate the leak if it is from water pump and also from egr cooler. Lets cross fingers that it is the case.

Whatever it is, we’ve decided to wait till the new year, car isn’t over heating and we have no long distance plans, at least not for a few months anyway.we will just keep our ears and eyes peeled for any drips or noises.

Assessment approved 🙂

Thought about one thing. Your car, does it have webasto? They are known to leak from time to time. Especially the v55 pump, but also from the housing itself. Worth checking out.
