So a little bit of a rant.. I was driving today minding my own business, and btw only drove down about 2 miles before all this happen. My car goes into limp mode followed by a engine temp warning. I say okay ill drive moderately like its telling me too. my car at full throttle is unable to make it past 10 mph which is causing a huge amount of traffic behind me. Then i get a new warning saying my engine is overheating pull over immediately. I pull over and now my car is smoking like its on fire.

I am not happy the car has less than 4000 miles and ive had it less than 3 months this is ridiculous.

Has anybody had this problem.

My car has just over 6k miles on it, and after 80 mins driving 80-85 and 10 mins driving at 100 my cars temp didn't even make it to the 250 in the middle. It was about 75 degrees outside here in Houston.

The coolant on these cars are exceptional. If you're having this problem it must be specific to your cars radiator/fluid balance/intercooler. Absolutely no reason this should've happened.

Water pump. When you get a high temp warning you need to stop immediately and shut it down...

You do realize the temp gauge is OIL temp, not coolant temp?

If the car goes into limp mode, pull over and shut off the car. It's the first fail-safe the car attempts to prevent damage. Given you continued to drive it till it smoked...

Never had problems with my 328i *knock on wood* but when I owned my 07 G35, it went into limp mode because of overheating (fan and thermostat were faulty) and decided to just get it towed.

Come to think of it... You're right. Thanks for the correction on that one lol. But that shouldn't change the fact that it shouldn't be overheating.

The problem is there is no indication of the coolant temp so you're essentially driving blind. If you get an overheating warning you need to stop. I think there are a large number of folks who don't understand that they're looking at oil temp which is a completely different operating range than coolant. I also have a feeling many folks don't realize that the electric water pump doesn't run constantly while the motor is running...

As some have said here, if your engine shows signs of overheating, pull over and turn the car off IMMEDIATELY.

Sorry about your luck though, no reason that should have happened particularly since the car is so new.

I did pull over and let it cool down for about 15 minutes. Plus the warning said drive moderately not pull over and dont drive. I was gonna let it cool for ab hour once i reached my destinTion which was literally across the street from where my car started to smoke.

As for coolant and oil temp, my oil temp was over 260 which its usually at around 240.

I should be hearing from BMW tomorrow to see what the problem is.

[amf]

burn it up and get motor replaced by warranty.

I do know from "old school" knowledge that when a car is over heating you should open the windows and turn on the heat to let heat out of the engine compartment. Once you've come to a stop put it in neutral and give a little gas to jostle some fluids around. Not sure if BMW's still work the same or have evolved too far for me to understand them anymore... But that's supposed to work.

That would only apply for older cars with a conventional mechanical water pump. With an electric pump that's not functional you'll just do more damage. Always shut it down and don't drive it at all. Even after allowing it to cool.

So this seems to be a water pump issue? Separate form that of the high pressure fuel pump? Is there an updated water pump to rectify this problem?

[reprod]

This may just a problem of one bad unit. Our vehicles are mechanical and things do happen. OP, just work with your dealer to get the problem resolved then get back on the road and enjoy your car again. Put all of this behind you.

if it is a failed water pump, it is one of the few that I have heard of failing in the F30. If true, it does not indicate a design fault, but rather an anomaly.

If there are multiple failures occurring then a design issue may exist.

too small a data-set & too early to tell .

Could also be a failed thermostat, stuck in the "closed" position, and thus not allowing coolant through.

[Bahn360Photo]

this is why there are a lot of limp modes, something with the fan regulator and fan sensor

[RoundelM3]

7300 miles so far, and only problem was an auxiliary cooling fan for the aux radiator in front of the left wheel well. There was a batch of bad fans that made it into production, and quite a few cars were affected. It did give me a "drivetrain fault" warning, that would go away and then re-appear. Once diagnosed at the dealer, it was replaced immediately and no further problems since.

It's a bit irrational to compare a single event such as this to the HPFP issues of the early N54. Stuff DOES actually break believe it or not. It's not automatically a "problem" or "design issue".

No comparisons drawn in my post, merely trying to distinguish these issues from one another.

I understand parts can be defective every now and then. Historically, that has not been the case with BMW, it's usually a faulty design (early n52 water pumps, n54 fuel pump, n55 fuel pumps, ...). So in fact I would assume the worst here.

One can only hope this is not the design which is defective, and it's an isolated incident.

Just because it says 'limp home' mode, and that you can continue your journey at moderate speeds, doesn't mean you automatically can. You are supposed to use your judgement a little bit too

[Pauleebe]

I fail to see why anyone with that low of mileage and that new of a vehicle would do this. If your car is telling you to turn it off, then surely something is very wrong. On top of that, you have BMW's warranty and they'll tow it for free and fix it with a loaner to boot.

Just no reason to be in this situation. Hopefully nothing was permanently damaged.
