Mein Auto: 2008 BMW 750Li
2008 750li Engine Overheat & coolant reservoir Cracked and hose burst

Yesterday in 104 degree Vegas heat my 2008 BMW 750li overheated. As soon as the "CAR OVERHEATING ... DO NOT DRIVE" warning appeared I instantly turned the car off and opened the hood to let the engine cool. Sadly it was too late and all i could hear was the sizzling and spraying of the coolant which emptied the tank and left coolant running down the gutter to the end of the street... This went on for about 10 min or so. I was thinking to myself great how bad can this get and thought about the expense of towing, time without a car, repair bill etc. I then called my S/A who was quick to give me the contact number of BMW Roadside assistance. Thinking this was going to cost an arm and a leg found out that the assistance and tow would all be covered under CPO warranty. Relief! The tow truck picked it up in 30 min and towed to the dealer at 6:00 last night. My S/A just called to say the car is being worked on and everything is covered under CPO and that the vehicle will be done this afternoon. Currently very thankful otherwise im sure this would have been at minimum $1500??

Wow that is crazy that it just burst like that on an 08. With such low miles. I wonder if your moms car is next??

Its really not a big deal though its just the reservoir, had it be the tank it would have been a lot more expensive.

yeah luckily this entire experience has been minimal. Just sucks not having my car but definitely was lucky it could have been much much worse. We are praying nothing happens with my moms. She has the extended warranty but it will be much more costly than with mine. BMW quoted her $1100 or something around there to fix the trunk pistons not covered under warranty. Currently her power trunk is not working. I also have to adjust the left headlight as its pointing down pretty badly.

I have a video of it as well just cant figure out how to upload it

*update* picked car up at 3:00 made it 2 miles and a/c went hot and misfire occurred then engine temp high drive moderately came on. Dealer told me to try and drive back if able... Drove 200 feet and light came on again. Waiting for BMW roadside assistance to come tow the car back to the dealer.

Try to let them check you entire cooling system, sometime is not just about the cap problem, try to check the water pump, your radiator and fan, park somewhere quiet and turn on your ac if there is no fan sound, then probably your fan is not working. any one of them can causes the overheat. Good luck man, keep us posted

Your entire system is letting go dude (prolly long overdue, whats mileage?) and they're not going to replace everything only as needed upon inspecting for damage or whatever is most obvious. Make sure they properly diagnose and fix. (If your relationship is good they'll prolly make it good) I hope your HG is good. Or no warpage or crack in the heads. Thats the WCS though. Probably just multiple hoses etcetera i wish you the best of luck

Thanks for the advise on what it could be got it towed back to the dealer it's the fan. They are replacing the fan and going from there. Dealership S/A offered car while mine is being worked on and also offered on any of the vehicles in our garage a full dealership as they do when they take cars into inventory. They also waived the deductible which was only $50 to begin with. The car isn't like some of the others on here not super high milage or anything like that... Have a little over 60,000 on it always maintained etc. it is what it is. Standing on the side of the road for the tow truck for an hour wasn't fun but things could be far worse. The head tech also came out to talk as well and explained what he did and what he found said he would work on it himself tonight. Will keep you all updated.

Good to hear it man, i thought the same, it maybe the fan problems. Take care of your cooling system, I changed the entire system last year due to my poor attention on it. BS, Are you coming to Bimmerfest east meet on this weekend?

Thats awesome. I guess i always expect the worse from these cars. But it also helps to find out its something no where near as bad. Sounds like they are taking care of you and thats a great thing to hear.
