Thought I had a leak in the coolant expansion tank so i got that replaced and also the hose on the underside of the tank. New cap and o ring on the expansion tank too. I dropped it into the garage again this morning and told them I think they didn't fit something back right, and he said from a quick look maybe the system is over pressurising and coolant as being forced out the overflow on the tank. They will do a compression leak test on it to figure out what's going on.
Has anyone had similar issues on 3.0 TDI a7? Some research on the internet points to maybe egr cooler or head gasket :( hopefully it's nothing too expensive. No codes are thrown or high temp alerts. If it wasn't for the level dropping and damp patch On the driveway i wouldn't know any different. It's a pain in the *** topping it up
