Interestingly, while I didn't have to add any coolant to my M235i's engine (yet I'm at 35kkm) - I did with my Golf 7R (same age, even slightly less distance covered), twice! The Golf has been the first car in my 47 years of driving which needed this (well - apart perhaps from a couple of "car-like" machines manufactured back in the righteously gone, communist era in Poland, by the Polish state "car industry" of those dark days). He said that during routine service they always make sure to "top off" the engine coolant The light went away but I was worried about a possible leak somewhere so I called my BMW dealership and told the service rep who nonchalantly stated that this was normal for BMW turbo engines, but couldn't really explain to me why. Once BMW replaced that part under warranty it never needed another drop of coolant.
#Bmw coolant low cracked
It had the classic cracked overflow reservoir. We've had 6 BMWs and none have ever needed a top off of coolant except for our 2008 535XiT. My guess is that they have a shitload of overpriced BMW coolant which they need to move - and they've found a way to do it. Service advisor was unconcerned and they made me pay for the gallon of BMW coolant which cost several thousand dollars (O.K., that's a slight exaggeration, but it was expensive). I was a bit surprised because I had my Z4 for 5+ years, my 128i ragtop for almost 6 years and the X1 for 3 years and never had to add coolant. Only had 25K Kms (about 16K miles) on the clock. If they put in standard green Prestone or any OAT coolant (typically red or orange), you need to have the cooling system flushed and refilled with the correct coolant to avoid future corrosion, sediment or plugged radiator issues. I've never had to replace the engine coolant of any of my other cars (non-BMW) before and wanted to get other thoughts on this? Should I be worried about a potential leak somewhere?ĭo you know what coolant Midas used to top up with? It needs to be nitrite, amine and phosphate free. He said that during routine service they always make sure to "top off" the engine coolant, and that if the low coolant sign came up that I could "swing by to get the coolant topped off" The car is about 2.5 years old with 20k on the odometer. I watched the technician put about 2 quarts of coolant in the resevoir.
I was worried about it and took it to a Midas just down the street from my home. I'm having the main expansion tank / "radiator cap" / fluid level switch replaced next week during a 60K service interval, and hope this cures the problem.So last night I was driving home from work when the "Low engine coolant" sign came up on the dash.when I started the car this morning the light immediately came back on. The separate mini expansion tank for my intercoolers seems to be holding up fine, but I ordered a new cover lid as a preventative measure (cheap insurance courtesy of ).
#Bmw coolant low verification
I've only got 59,850 miles on the odo, and my first thought was the dreaded turbo coolant lines were the culprit, once again (they were all replaced last year, and ended up not being the source of my leakage).įurther investigation revealed the expansion tank coming off the radiator was slowly weeping fluid at the top/sidewall seam a problem that was not obvious at first, but after some online research and verification by placing a clean white towel along the seam after a spirited drive, the blue-tinted coolant leak became readily apparent. I had the "low coolant" alert earlier this month, and ended up having to put over a liter of fluid (50-50 mix of BMW coolant & distilled water) back into the system just to bring the levels back up to normal.Īs the original owner, this is the first time I've experienced this issue.
