Guys, quick check that if I add additional coolant much more over the ''maximum'' level, which almost fill up the reservoir, does it cause any harm to the vehicle?

I would suspect a large majority of the coolant reservoir failures (leaking, seaping) are due to too much coolant (above the max line) and the resultant excessive pressure build up.
Unfortunately after every service at the BMW dealership, they “top off” all the fluids and end up adding too much coolant. I ALWAYS am removing excess coolant from both reservoirs. |

This is the coolant level of mine now, is it still too much or it's good enough? The coolant level is a tiny little bit over the Max level line |

Also keep an eye on weeping at seam coolant expansion tank. I've had two fail in two f80s bought new. It's a very slow leak over time so takes some convincing to get it replaced under warranty since the pressure test checks out ok.

Depends on age of your car. There was a Magenta coolant before they switched us to Blue. It was for easy recognition that it's "not green". The color also made it easy to know when it was flushed through (with Blue). I recall seeing a chart that allowed certain colors to be mixed and others not.

This is happening to me too, mine seems to be very weird, at first I open the cap and see that the tank is empty and then I top it off.
I then try bleeding procedure and this foams starting to show up, not bubbles but literally white foams. After I park the car for half an hour, the white foams disappear, but it shows up again if I try bleeding the system. So this can conclude that my main reservoir take is leaking? or Intercooler? |

Man this thread had me running to my car to check my coolant levels.
MY2015 55k miles. My TMIC reservoir looks great. Nice and full. My engine reservoir was empty though. Should I be worried or just top off and continue my day? |

Fill tank
I think I saw two posts that talked about overflow tank showing white foam/bubble. I saw the same thing (image attached) with level near bottom end. It stayed on that level many months. I just added a bit of coolant, test drove and foam/bubble is gone.
Before adding coolant: Charge air temp was about 20-22 degree above ambient while cruising. After adding coolant: Charge air temp was about 18-20 (saw as long as 14) degree above ambient while cruising. I think if there is no leak, adding coolant can help with foaming. It looked like water was rushing through the tank and when the level was low, and it was causing it to foam up (many small bubbles). After adding coolant, I can see the water stream but no more foam/bubble.

Quick question, if intercooler/reservoir tank replacement is needed (heat exchanger not included), does the system need to be bled when coolant is added or no? Thanks.

Depends on how much fluid is lost/air has gotten in. Wouldn't hurt to do it either way
