CHECK COOLANT LEVEL msg - BMW Forum

000is · 04-01-2008, 01:20 PM

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!

The errant coolant warning could very well be the coolant level sensor, which goes bad sometimes.

The beeping noise might be your clock. There's a setting that causes beeping every hour on the hour.

i hope the fix is as simple as that...
it started a few weeks ago and pops in and out with the message.
stopped when i filled up the antifreeze almost to the top but came back a week later.

the beeping sound shouldn't be coming from the clock since i don't have any alarms or memos programmed (never have)...drives me nutz when it goes off!

Might there be an aftermarket alarm system installed on your car from before you owned it? That was the case on my E36 M3, and it took me a while to figure out what was going on.

don't think it's the alarm since i don't even use it...always off.

Im 99% sure its just a faulty sensor. Its ar REALLY common thing. If your expansion tank is in ok shape, and your not leaking any coolant, you have nothing to worry about

first off...NICE pic of your car.

yah, i check the underside and doesn't seem to be any leakage so (hopefully) just a bad sensor.
still better safe than sorry since i've read about head gaskets, etc cracking from the overheating.

thanx for the help!

the beep might be for the outside temperature, i have that also... i know its annoying but i live with it

I bet you the beerp is related to the Memo function on your OBC (on board computer) which is that message system where it says low coolant. The Memo button looks like this roughly .))) press it to make that symbol disappear off your OBC screen next to the clock.

Sounds like a faulty coolant sensor.

000is · 04-01-2008, 05:09 PM

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 ([COLOR=blue ! important][COLOR=blue ! important]antifreeze[/COLOR][/COLOR] 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...?

water leaking in has to do with ur weather seals...

its the black rubber things around the inside of ur doors...when they go bad, water gets in...

its called the door seal on pelicanparts.com

the water is actually coming thru the vents underneath the dash so i'm assuming the other 'fluid' must have come from there as well...
no H2O leaks from the door whatsoever.

meaning the vents just above your feet or under the dash.

no its not a big problem , when u look at the tank of antifreeze it looks full but still put some in that should help, if it still does the same theres a sensor in that same tank that has to be changed, the other beep u hear is nothing just a reminder , could temp , speed, or other, good luck , i had the same problem thats how i fixed it.
