Check Coolant Level warning

[myndgone]

How's it going everyone...here is my first post, just got a '99 540i 5 days ago and a buddy told me about this forum. Hope to find tons of cool people and useful info.

I have a problem already
Check Coolant Level warning light keeps popping up at startup. I check the level, topped it off (it was maybe 1/4 lower than the top) but the light still stays on, together with check engine light. No visible coolant leaks anywere.
Car has 76K.
Any places to get this checked, other than dealers?
Thanks in advance!

Your coolant has to be filled all the way to the top, if the light is still on, then your sensor is busted and needs to be replaced.

hey, thanks for replying, man.

coolant is filled all the way to the top, so i guess it might be the sensor then.
any idea how much they go for and if its possible to replace them without going to the dealership?

I have a 98 and I just had my coolant tank completely replaced (thermostat needs to be replaced too) ... couple of plastic peices inside broke off. It wasn't that expansive, I believe the tank was about $200 ... pm me I'll give you my mechanic info if you need.
