Yes - will do, as I've seen that reported here in various posts...[/QUOTE] Car went in for first service, the coolant top-up and ongoing engine light issue was raised with them. Dealer couldn't find anything wrong... but they did a software upgrade which they said should help(!) and also deal with the intermittent rear reversing camera blackouts; telling me to come back in if they happened again I see that my car is now with i-step version S15A-19-07-553 No obvious (visible or driving experience) changes that I can tell. Apart from I now have the analogue clock option for the main display! |

So after 7 or 8 times having to top up the car after seeing the low coolant warnings.
BMW finally agreed to bring my car in for a throughout inspection for warranty because the car was leaking coolant down the left front bumper after every trip when the engine has been running for a while. I guess everyone with a recurring issue should contact BMW and get their G30s checked ASAP. The low coolant went away for around 20000km and now it is constantly asking for coolant every 3-4 days. It is that bad and I forced BMW to take it in by using their Roadside Assistance and towed the vehicle back to the workshop. It seems to get worse as the vehicle ages. Mine is one of the first G30 unit built in Germany 2016, odo is now around 54000km. I’ll keep you guys updated. |

UPDATE: BMW found a leak in the radiator and it has to be replaced. Strange thing is they seems to conveniently have a ready supply of radiators in stock and it can be replaced within days, whereas the wireless charging pad and coin compartment had to be flown in from Germany which took 2 weeks. My guess would be this leak issue is now recognised as a known issue, pretty sure I’ve seen another member here had to get their rad replaced for similar issue.

hum, I wonder if it's only specific to earlier build, guess most of the later build hasn't gotten to those miles yet to tell...

I pretty much accelerated this to a point where that tiny leak developed into a crack and it started to drip in puddles. Pressure test indicated a leaked expansion tank and it was replaced under warranty. I filled my coolant almost 8 times already if I'm not wrong |

My car has displayed this alert twice now so I will get this booked in as a warranty job.
First occasion was after being left for 2 weeks. Subsequent start did not display the message though. Same agin this morning, car had been parked for a week and same warning but not on subsequent start. |

Great to hear the positive results! Hopefully the info I provided will act as a base for people to confidently talk to BMW about this issue. It is a common fault with the amount of people mentioned this warning in their vehicles. It's a matter ofntime before the loss of coolant developed into a visible coolant leak. Get that fixed before your warranty runs out, as far as I can see on the BMW warranty job card it costs a few thousands dollars for this job and the wireless charging pad.

2018 540i xdrive M sport. ~10K miles, 10 months of ownership.
Started up this morning, after sitting more often than not in the past 2 weeks. It has been cold here, into 30s at night. Coolant level low warning. Both tanks look empty. No leaking on the ground that I can see. Both caps were very tight, the bigger tank has what looks like some orange residue on the inside. I'll try to get some pictures. Waiting for my BMW coolant from amazon to refill. |

Look for a light colour powder like substance in the engine bay, that will be the evaporated coolant. My dealer shot a video and posted to me so I could see.
Leak can't be much so it must have taken a while to escape. |

I thought I was low mileage, just 7000 miles a year and only used at weekends.
In uk warranty is 3 years so I have about 3 months left so glad this popped up now. Like anything with bmw ,suspect this isn't a cheap fix if you're paying for it your self. Only downside is my time to get the car up to the dealership, excuse to have a day off work and look round the dealership at the new and used cars. Usually something interest to look at, 2 M5s, alpina 3 series, 8 series convertible of note this time. Last time saw one of the rare 760i s. |

If your G30 gave a low coolant warning more than once then chances are you're in for an expansion tank replacement down the track. Either out of your pocket or BMW's pocket is depending on how good you are at pushing BMW to do a coolant system pressure leak test. It's the second plastic tank i the engine bay with the smaller cap. Mine just cracked and leaked coolant, dripping into a puddle everytime I stopped the car. That's how I went through nearly 2l of mixed BMW blue coolant within a month....

I think time wise just about every bodies cars should still be in warranty ( bar possibly the very first ones that were produced) so worth a check for any signs of leakages and if you find any, get to the dealer.
Mine did do a pressure test and they positively found evidence of the leak as it leaves a light coloured residue behind. They also did a complimentary quick check over if the car , they noted tread depth on my tyres which were all good. |

Ok not a dumb question
There are 2 reservoirs in the bottom right had side of the engine bay as you stand in front in the car Unscrew these when the car has cooled down. I found them quite hard to unscrew particularly the large one requiring 2 hands to do so There is a marker inside with min and max , there should be fluid in there at least up to min. A torch will help see inside Looking below these reservoirs I saw a light coloured residue , not that obvious but there, again a torch helps If need to fill up use coolant mixed with distilled water 50:50 |

BMW admitted this issue and honoured my warranty, I'm not trying to do fear mongering but it's rather a PSA....great vehicle but they could've done better. I'm surprise they haven't done a recall on the expansion tank already. Based on the number of people confirming the loss of coolant in this forum alone it's quite alarming. |

https://www.shopbmwusa.com/PRODUCT/6...REEZE-COOLANT/ think just buy another two bottle stick in the trunk just in case as well edit: I see some green residue on one of the hose, can't see any green liquid inside the engine compartment, think will just got to dealer ask them to do a proper test... |
