Coolant fill normal?

shizmd · 07-23-2017, 10:13 AM

Hello I have a '13 x5m with 70k miles. Have noticed recently that I've been filling up the coolant every 2 months with maybe 16oz total, 3/4 in reservoir and 1/4 in turbo reservoir. Do I have a leak? Do I need to get a coolant pressure test? I have some UV dye that I could play with. Engine has never overheated and low coolant light never came on. The level appears to be below the minimum marking. Advice ? Is there a common leak on this vehicle? Summer here and temps been running low to mid 90s outside. Thank u in advance

No, adding coolant is not normal. On the n63 engines, the turbo coolant lines were prone to leaks. I'm not sure about the s63 though. Have you checked your coolant reservoir for leaks? They are a common failure point for E70s. I'd get a pressure test done.
