My 2017 430i was losing coolant slowly for months, and I kept topping it up. Finally got tired of the smell and took it to a place that specializes in German cars. They turned out to be a proper Dubai BMW Leak Repair Specialist and found a cracked expansion tank and a weeping water pump seal. Replaced both, pressure tested the system, and topped up with the correct coolant. No more drips, no more smell, and the temperature gauge is rock solid. The mechanic showed me the old parts – the tank had hairline cracks you could barely see. Total cost was very reasonable and they finished in half a day. If your BMW is leaking anything, don't ignore it like I did. Get it checked before it overheats. Very happy with the outcome.
