Hi,

I had a water pump issue last week so I got it replaced. I never actually paid attention to the temperature, but mine goes over to 250F (about 120 in celsius).

Is this normal??? I think I've seen it goes up to 220 or so, but not 250.

When driving my baby real hard and it's summer in Texas I've seen it pass 250 a little bit but usually it doesn't happen

[littlehuman]

PureE92 Thank you. It sounds like I need to take it to the shop again.

That seems normal, our computers have different temperature setpoints based on driving conditions.

See page 67 of this tech manual:

250 Deg F is close to the eco mode setpoint. Sounds normal to me.

[littlehuman]

Thank you

Um..if that's the case...it probably me who never paid attention to the temperature. I've never seen it to go over 220F.

[TrAcK TRaP]

most I saw 240 here when I drove it so hard on summer with little over 80 degrees

If I'm not mistaken the N51 runs hot for emission reasons. But I usually 205-220 is a good range. 250 seems a bit high for any engine though.

[hassmaschine]

why are we talking Fahrenheit on a car that is all metric?

anyway, the eco mode is 112c. that's 233f. 250f is 120c and overheating technically.

are you sure whatever gage you're using to get that number is accurate? because at 120c the yellow coolant warning light comes on. if it is truly running that hot, your waterpump and thermostat are probably done.

Are you confusing the oil temp gauge with water temp? On most of our cars, the gauge shows oil, not water temp. We just get an idiot light for water overtemp.

check your thermostat its next to the water pump. that can also be an issue if it failed closed

this is the N52 forum, there's no oil temp gauge. he's looking at it through an app or something.

[ashmostro]

Got it

[Three_thirty_I]

Seems rather warm to me! And is higher than the high temperature Eco mode.

My N52 has an oil temp guage... The engine doesn't determine if he has an oil temp gauge; sport package does.

[hassmaschine]

I have the sport package and it's an mpg gauge. Are you sure?

[PureE92]

I think the e90 has the mpg gauge and the e92 had the oil temp gauge

Actually Pure was correct, it isn't the sport package but the e92 came with oil temp while apparently e90's got an MPG gauge.

[hassmaschine]

Interesting!

[ashmostro]

Well then that makes a lot of sense and doesn't appear to be any cause for concern, OP.

I also seem to think it's an E92 thing - very odd. I do like the econometer that my E90 has, but I would prefer to be able to see the engine temperature, and it's not as if there is not enough space on the cluster to have added a temperature gauge.

[EndOfAnEra]

07 E92 328i w/ sport package here, I have an oil temperature gauge.

[ashmostro]

Most importantly... As it now appears to be confirmed an oil temp gauge and not coolant, a reading of 250 degrees makes perfect sense.
