Coolant Warning
Hi,
I'm following the forum for some month now but this is my first post so Hello All ! I bought a brand new 2012 X3 35i last month and after only 1500Km he gave me this morning a warning saying i need to put some more coolant. I went to my dealership and the technician add something like 2L in the tank and told me it was nothing and it was normal to lose coolant ... I'm really not a specialist but it seems weird to me first to say that this warning was nothing and second to say it is normal to lose 2L of coolant after 1500Km !!! What do you think ? Thank you for your time |

Oil yes. Coolant no. A new engine can run hotter than a run-in engine due to the metal surfaces not being microscopically smooth until run-in and therefore creating higher friction. And it is well known that the X3 has an operating temperature of around 103 C which is 5 to 10 C hotter than usual, however the coolant added to the water is designed to raise the boiling point as well as the pressurising of the coolant itself raising the boiling point. So there should not be an issue with the car overheating and spewing excess coolant out of the escape valve when it gets hot. So if I were you I would take it back to the dealer and demand a pressure test of the cooling system and inspect the oil to ensure it is nice and clean with no "milkiness" to it. Two litres of coolant is a massive amount to loose. If your car is fine then I would suggest it was under-filled when prepared for you. The only other issue you could have is the radiator pressure cap is faulty and is opening at too low a temperature. That is not uncommon. |

I had my coolant refill at the first 11K miles here in Northern California. I was rather surprised because in my previous VW, I never had to top my coolant in 6 years of ownership.

Dealer response sounds a bit dodgy IMO....probably a small leak somewhere in the compartment and they just can't be bothered to check.

o One when i putted the car in sport mode, i don't know why but the car jumped at 5000 right away so i let it go down o One when i thought i was on [D] and i was on [P] and when i started the car at the light stop it did a big Vraoummmm and it goes to 5000 In both cases, the car was hot and the temperature was more than 100C I hope i didn't abuse my baby ... For information : I check the oil level and i'm at the maximum. Anyway, i called my dealership and told him they should really check if there is something wrong cause if it's the case, it would probably cost less to fix it now than to wait to break the engine ! Thank you guys, i'll keep you posted |

Just for information :
I did what you said, i checked carefully if there was not a leak somewhere and i saw one just under the coolant tank. It was just the probe that was leaking and the mechanic apologize and told me he should have check . So now the are ordering the part and this should be fixed within 2 weeks. Thanks again for your help Happy holidays ! |

My refill coolant warning light came
On today at start-up and then the little yellow warning light was on the dashboard. After driving to my destination, turning off the car and then re starting up the car, the warning light is now off and no more warning?? Is it just a false alarm or cuz the car was too cold? Thanks |

I got the low coolant alarm on my car last night (just shy of 15k miles). I checked the level this morning and there doesn't even appear to be coolant in the reservoir. I am due for a service this weekend but I don't feel easy driving around the rest of the week and the 100 miles ride to the dealer with an unknown amount of coolant.

I errantly posted an experience with low coolant previous to this that I removed - got my Bimmer issues juxtaposed (the rear brake light was the issue that 'fixed itself'). My experience with Low Coolant matches many of the folks that have already posted. Light came on, checked coolant level, level was BONE DRY, added non-BMW Prestone coolant (yellow) - almost half a jug. Took it to service a week later, told them about the low level and asked them to check the system. They inspected the coolant system, found no issue. They also topped off with OEM coolant - again. That was four months ago. No issue since. I never observed any venting of coolant / leaks in the engine bay / overtemps prior to the light/during/or after.
Why are so many owners having this issue? Are they under-serviced by factory robots? Lotus7, any idea?

Thanks, Lotus7. FYSA, on your two sub points:
Distance driven: in the case of my car, I'd had the vehicle for three months, driven it 5000 miles (one very long cross-country trip - 3000 miles in there). Bought the car at the end of June, light first came on at the end of August/beginning of September. Environmental impact (temp/barometric pressure/humidity): It was purchased in Vegas and was moved to the WA DC area. Drop in 1800', humidity level significantly higher - relatively similar summer temps. I reckon if it came from the factory low the light would have illuminated earlier. Perhaps it was just a loose cap or something. I'd guess running the car for around 6-8 hours a day for a week and a half could have something to do with it, too. Who'd have thought a closed-loop(ish) system could be so open? Good evening to all!

No idea what you heard. Could you have not placed the cap back on? |

My car is in service right now. The service rep told me that they did a pressure test and were unable to discover a leak. He assured me that this is normal... I guess I will just keep a close eye on things.

I'm also at 7500 miles and have an oil change scheduled for next week. I'll check my coolant level tomorrow. I expect that it will be an automatic check on the BMW tech's part, but I'll mention the coolant level to the SA if it looks low.
I'm bringing a sample bottle with me, and asking for an oil sample when they do the oil change. I'm curious why my X3 wants a 7500 mile oil change, and what an oil analysis will tell me. |

I was also very surprised when I got a "low coolant warning" earlier this month. Dealer said to just add some water since adding store bought anti-freeze could damage the engine. I added a full 500ml bottle of water and the indicator is back to "max".
Next service is very soon so hopefully they'll flush the entire system. |

Coincidence?
Have owned 3's, 5's x5's and 3 x3's.. Had an overheating problem with a 318 but only after a head on with a UPS delivery truck.
Took delivery of custome ordered 2012 X3 in late April... Low Coolant level warning lit up the night Sandy hit... Checked the coolant resevoir and it was bone dry... Next day BMW Assist towed the car to the dealer... Diagnosis: coolant evaporated... Same thing happened with our 2008 x3 - turned out to be a faulty water pump.. Got stranded over 100 miles from the nearest dealer.. So, once I relayed this info and asked if the techs ran a pressure test on the system, the dealer's trouble-shooter decided to keep the car another day... He even told me that virtually the same thing happened to his wife.... I'm no expert but are all these reports of trouble REALLY attributable to excess evaporation? Anybody sense that this might be some kind of desiogn flaw? I'm ready to invoke MD's lemon law! |
