Coolant on garage floor.

[Tramel84]

Coolant on garage floor under my car. Check reservoir still at max, slight white coolant residue splash around tank. Remove engine cover looked over hoses and didn't see any indication of a leak. To much fluid to not be a potential leak from the car. Any help will be grateful appreciate. I did have the low coolant warning light around the holidays. Dealership top off fluid. I did purchase some coolant as well just for future alarms. Thanks for all the help

I would get the dealer to check it again. You are right, this a lot of coolant, it has be coming from somewhere.

Vehicle went to the dealership, pressure test conducted no leaks. 🤦🏾*♂️🤔. However thrust bushings are leaking so warranty replacement.

Turbo coolant lines leak on this car.

Not sure if the line was leaking. They did the test and no leaks. So I'll just be on the look out for it.

I had a similar problem a few weeks ago. Mrs H62 reported the low coolant warning, so I topped off the reservoirs. Seemed OK for about a week, then happened again, but this time I noted a LOT of coolant on the ground. Called the dealer, they sent a tow (and a loaner). Report is that both a coolant line, and the larger reservoir were cracked. Parts ordered (covered under warranty), but snow-ma-geddon has delayed delivery.

What year 7 do you have and at what mileage did the problem occur?

It's a 2018 750LI, with just over 31K miles. Bought it as a CPO last year.

I see, so your 4 yr original factory warranty is covering it, not your cpo, as I bought cpo also but this wasn't covered as I was out of the original 4 year window

I have a 16 740i with 40k and I had topped off the reservoir as well. Took it in and they stated all was well. Pressure test no issues. I'm still in shock. The coolant came from some where. My factory warranty is up this April thank god I have a secondary warranty as well just incase.
