T6 coolant leaking

[Poobarr]

Hi everyone

We seem to have a major issue on our VW California 2017 it’s the 204 brake horsepower TwinTurbo 4 motion. The vehicle was in for a serve oil filter change, about a week later or so I used the heater. Then we had a coolant leak. The fault was diagnosed as the EGR valve completely self-destructed. The EGR was replaced along with some of the connections and the engine was drained of the coolant. The parts used with VW parts. The cali then ran fine and engine pulled as normal. Subsequently the vehicle still does not hold coolant….

The engine seems to run fine but the coolant is draining. There does not seem to be any obvious leaks on the ground, so I’m presuming the coolant is going back into the engine?

Has anyone come across this before? The garage has had the vehicle in twice but doesn’t seem to be getting any further forward (awkward as the garage is run by a mate). I have another friend who owns another garage who is happy to look at it but I am now considering sending it to VW. Any help would be greatly appreciated

Sounds frustrating. If there’s definitely no leaks externally (can be leaking and evaporating) then logically it can only really be going into the oil or ‘burning’ off - surprised a garage can’t establish this.
