Coolant tank levels dropping

[Don1971]

Audi A6 my sons car is coolant level dropping weekly but no sign of a leak….But his car from Arnold Shark with a 3 month warranty which lukily he still has 2 montjs of it. Any idea what it can be. Car does not over heat

If it's a diesel it may well be the EGR cooler. That's an expensive repair so he should return the car to the dealer before it is too late.

He is calling them tomorrow as the car is still under warranty….

Whatever the cause, and it may be something else, get the dealer to sort it out.
