Hey guys, my car overheated yesterday for the second time within the last 3 days. I would just pull over, turn it off and let it cool down. When I opened the hood, I noticed that there was some coolant that was released. Luckily for me I was only a few miles away from my house. I finally got home and scanned my car and had 2 codes. Both have something to do with my water pump. 2 weeks ago I also got a low coolant warning. I went to the dealer and picked up some coolant and just topped it off. Also, my car has been making this weird vibrating noise for about a minute after I go on a long drive and turn the car off for the last month or two. I put my car through the water pump cycle or flush thing and made a video and this is the weird vibrating noise I'm talking about. Tell me what you guys think. Has my water pump failed?

have it checked out. My friends 335 had a crack in his radiator and BMW replaced it.

is there anything i can do temporary so my car can run just for one day? like fill up the coolant or something?
i have my other bumper at ltbmw and need to get it put on before i go to the dealer because my current bumper is too low. it is about an 80 mile trip there and back.

Why don't you just pressure test the cooling system to see where the coolant is coming out from? BMW's usually crack the the radiator tanks or overflow tank. If it's a large crack and cannot hold pressure, then there is no way you can make it 40 miles.

[Mr. 5]

The noise after the car is off is normal to cool the turbos.
I think the pressure test is a good idea.

If you threw 2 water pump related codes, I can almost guaranty you that your water pump needs to be replaced. Shiv had to do this with his car at around 60k miles. Same exact thing happened. Doesn't really seem like the engine accessories on these cars are as robust as the engine itself. If you still have warranty, it's a quick work. If not, it will cost you around $500 for the pump and 3-4 hours of labor.

But whatever you do, definitely don't drive it around until the issue is fixed or else its likely that you will be left stranded somewhere. Once coolant temps go too high, your dme will trigger a low power/low throttle limp mode which is decent enough for normal driving. The problem is that I can see irreparable damage being done with driving around with an overheating engine for too long.

Totally, it's the only car that ever has a water pump go out. You should stay away.

Yeah but the sound i hear in his video is not normal , sounds like a pump that is running dry and then seizing or something , then starting again and seizing again.

thanks guys and thanks calvin for your detailed response. i figure that is exactly what the problem is because i am at 63,000 miles. so i just dropped my car off right now to the dealers for the early bird service.

If a rare water pump failure scares you away, then you definitely won't be shopping for an S4. Google: B8 S4 water pump

The Evo also had a recall on water pumps...I know, i had one pop the weeping hole while on a road course.

Unfortunately, as someone else said, the accessories on a performance car are often weaker than the motor. My cache of spare parts for the track included pretty-much every accessory, belt. hose, etc.

[Bimmer This]

Did you say above that you saw a little bit of a coolant leak? I know that on come vehicles, their water pump tends to leak before they go out.

[ar design]

My water pump died at 18k. If you have codes, its the pump. No leaks on mine either.

hey guys i just got my car back today.
they said my battery that was the problem? i had low voltage codes
i had to buy a new one.
and now my car isn't overheating anymore and no more water pump codes..
anyone have an explanation on what the battery had to do with this?
but I am still getting that weird vibrating noise when i turn the car off. maybe mr. 5 was right? this is just for cooling reasons?
anyone else have this also?
thanks!

Holy crap dude WTF?

That noise is ridiculous.

There is a very unnoticeable noise when the car is off, slight humm. <--- NORMAL

Your car sounds like the 4th of july/ jack hammer... something is definitely broken.

shoot
any ideas what it could be?
i was doing some water pump flush thing that i read about in a thread. it goes on for like 12 minutes so it was just this sound constantly. when it happens when i turn my car off its only for like 30 seconds.
the dealer wrote vibrating noise-aftermarket equipment installed-coilovers
wtf??
and also..when I WOT the car now and come to a stop you can hear the fan pretty clearly for like 5 seconds and then it goes quiet again..
is that normal?

Sounds like your dealer already is trying to screw you over cause of aftermarket parts...

I would stop with the pump flush, I think your pump is toast in some fashion.

The pump recirculates coolant through your turbos after you shut it off (the car)to cool them down slowly.

Naturally, when you WOT the car, engine is going to heat up, so I suspect your fans are kicking on cause your coolant temp exceeded a certain temp...

I'd be concerned about your thermostat and the rest of your cooling system components at this point.

If you have BT tool, check your coolant temps and see how they are responding. Eitherway bring it back to dealer.

damn. i'm just going to have to wait for that specific part to break so the code shows up or whatever. otherwise the dealers not going to give a crap. I just recently had a new thermostat installed. one thing i learned about the dealers is that they'll do anything to just beat around the bush until the problem is right in your face.
anyways thanks a lot jpslick for your help.

[drunkm3nky]

which dealership do you go to? Irvine?

[klipseracer]

I had an over heating issue, it was a battery issue with my terminals, although my car operated perfectly fine. Electric water pump is better than a mechanical pump in case it seizes up and that can cause havoc on some cars with cams connected to that pulley.
