Coolant issues

[Peter56789]

I’ve been having problems with my coolant disappearing. I’ve had head gasket checked, my water pump and timing belt replaced egr cooler replaced. But my car still won’t hold coolant it’s not leaking onto ground anywhere as I’ve been watching it. I drove the car over a week ago and checked how much coolant i had in it before i set off and got home and it was roughly half full i went to check the car today and it had no coolant in the reservoir so i took the cap off and only a quarter of it came back into the reservoir. Thank you in advance for any help

I had a similar issue.
I took the car to VW to do a pressure test, and they detected loss through the coolant reservoir cap.
I took advantage of the situation and put a new reservoir and cap.
Solved my situation!
My advice is, before spending money unnecessarily, it is advisable to carry out the proper and correct tests.

Hi I’ve had all the test already carried out by a local garage and I’ve replaced the coolant cap already.

I had a coolant leak in another car due to a small crack in the radiator, but what happens is that it loses without being under system pressure, only when the car is at rest.
A few drops may fall, not enough to fall on the ground, they remain in the engine noise insulation cover, and with the heat they evaporate.
