I’ve noticed a small puddle of coolant under my 2017 520i for the past few mornings, and the expansion tank level keeps dropping. Pretty sure the radiator or one of the plastic end tanks has a hairline crack from all the thermal stress here. I don’t want to just keep topping it up and risk overheating in the middle of summer. Has anyone used a BMW Radiator Repair Service Dubai that actually tries to fix the original radiator instead of immediately pushing for a full replacement? I know some shops just swap the whole thing because it’s easier, but if it’s just a small leak I’d rather repair it if possible. Also curious if they pressure test the system afterwards to make sure there are no other weak spots. Would love to hear from someone who’s been through this before I pick a shop.
