2006 330I overheating?

hey guys, my Temp indicator keeps coming on, but when i restarts my enging it goes away, is this an electric problem or not? and has anyone else experience this? it's been happening very frequently of late

Just the yellow indicator? Not the red one (yet) correct?

Two things:

1.) Check your coolant level: Open hood, look to far left, see the black lid? Turn it (SLOWLY IF ENGINE NOT COOLED DOWN), and check the bobbing mechanism to make sure there's an adequate amount of liquid inside, there should be a level meter readout on the side of the case. If it's VERY low, get yourself a jug of distilled water and some BMW Antifreeze, and mix 50/50 THEN pour in until you get enough in there to make the float come up to an adequate level. At some point, get a coolant flush done at an Indy shop. One near me in NH here quoted $64 + cost of the Antifreeze ($20'ish).

2.) Get your codes read, to make sure the electric pump isn't throwing out codes. Could be going soon.

If your pump IS going, you'll probably need to hop online and find yourself another good pump (don't buy a plastic one...go metal). You're possibly looking at around $400-500 if you can follow instructions and DIY. If not, prepare for more money throwing at labor (again, Indy). May need a new Thermostat as well.


Then again, it could be more complicated than this, but 9/10 it should be one of these two. FYI, I have the same car, and I had this issue as well, but mine was fixed by adding more coolant/distilled water (my float was a little too low, added a bit and it fixed it). Now, that's not to say that I too don't need to replace my pump, but for now, what isn't broken doesn't require fixing. I'm budgeting for a new pump though.

i checked the coolant level already & it was fine, so im guessing its either my pump or thermostat, i'll get the codes read and see what it says & yes, i'd like to do it myself. thanks a lot brother.

oh, i got the red as well, but when i turn my car off & back on, it goes away.

Welcome to Electric Pump and Thermostat land, population you

It'll definitely sort itself out and you'll enjoy you car much more if it truly is one of these two things. Think of it this way, once you get the pump replaced, you'll be happier driving your car, since you'll know you have a lot of worry-free (well, electric pump worry free ) miles ahead of you. The way I always look at it, is you plan to keep the car for a little while longer than most people keep their cars, the pump WILL go. It's not if, it's WHEN.

ok, so it could also be both right? which do you suggest to replace 1st, im not sure if im gonna keep the car, had it for 3 yrs, 83000 miles. thinking of getting an 08 535I with around 40K's.

The real problem thing is the Pump, the Thermostat shouldn't be your Go-To "ITS BROKEN" part. I'd get the pump checked out. A thing to note, the Thermostat in these cars fails in the "open" position. If you open your engine bay, is there a "stink" of some sorts? Oily? Or is it just the normal, humid, hot smell? If there's some kind of scent, you can bet that something's seriously overheating.

Get the Pump checked out. I'd be willing to bet the house it's the former rather than latter. Either way, it's pricey. But one is LESS pricey.
