newbie here...hopefully someone can help with this problem i'm having.
lately my '94 325is has been flashing the CHECK COOLANT msg (sometimes) when i shut off the engine...doesn't seem like the coolant level is low though?
I check it when the engine is cooled down overnite and levels are full.
problem with the overflow tank possibly?
also get a beepbeepbeep sound sometimes when i'm driving but no msg on the led screen?
are these big problems???
thanx for the help!

Some cars do this on startup/shutdown, it could be a few things. The float sensor in the tank could be bad, or the connections on the sensor could be corroded.
Yes, your car is going to explode.also get a beepbeepbeep sound sometimes when i'm driving but no msg on the led screen?
are these big problems???
Nah, chances are your MEMO function is turned on, it will beep three times every hour. This shows up as a O))) in a corner of the OBC somewhere, hit memo until that disappears.

I miss my BMW
yah...hoping it's a simple thing but just want to know what to point out to my mechanic.
i did read about other instances where even though the temp gauge was normal/centered the engine would overheat causing cracking, etc of head gaskets...let's hope not.
i don't think i've ever even used the memo fn but i'll check it out.
i also read about that temp issue where it beeps if it's severely cold outside...and it hasn't been that cold here in NYC.
thanx for the help CC!
Or someone set your LIMIT button and you're exceeding the preset max speed, or the temperature is below 37 degrees F, or yes, the memo is on.
Coolant sending unit could be bad, mine flashed a few times after I got a new rad, just added a few ounces to bring it to level and no probs since.
Expansion tank has a sensor that can go bad. I wouldnt worry about it too much, just make sure you have enough water/coolant

yup...the beep was from the memo being set inadvertently...thanx for that guys.
another thing i forgot to mention was that the passenger side floormat seemed to have some sort of fluid collected (antifreeze maybe?)...
and the other nite after it rained,
i opened the door to find that both mats had collected water?
sometimes when i get a car wash, water comes in thru the floor vents but never anything like this...?
replace the sensor
Far too much to list
I had that problem too. I had it serviced and flushed today, haven't seen the message yet.
I had that problem before, turned out that I needed to have the system bled thoroughly and everything's been fine since.
I didn't read any of the other responses, but this is classic symptom that you need to bleed your coolant system.
For the next week, once a day after a longer drive (30 minutes driving) pop your hood and using a Phillips screwdriver unscrew your bleeder port. I guarantee your problem will be fixed after doing this for a week
edit: after air comes out... makes sure you tighten it again

That is wrong info.. hot water will spray all over you. Bleed it as it warms up by overflowing the tank with water

what is coolant? jk...

I had the check coolant message too. I found that my sensor was fine and so were my levels. My issue was the black connector that hooks to the sensor. It was making a bad connection so all i did was open the black plug up (takes a small screwdriver to pry it open), crimp the connectors slightly with pliers, and close it all back up. No check coolant light since.
Just because it only does it on startup/shutdown doesn't mean it's a sensor fault and not really losing coolant...
My car loses about half a gallon a day right now, and the light only comes on at startup/shutdown if I don't top it off... (Yes, new rad/tank are on the way...)

car's with my mech now...he says there's definitely leakage coming from thru the vents (not the doors) so he's trying to locate the problem.
also there was a small leak/crack in the radiator and it was failing the pressure tests...hence the check coolant msg's.
suggestions anyone?
