Sorry man If you were in NJ... I would come out to help or at least provide company. Sucks that your WP gave up the ghost. Be sure that the mechanic checks the codes and how many times you have had speed deviation/etc issues logged. If you see like hundreds of codes stored... than the car was trying to speak to you.

What year car? Build date? Original car battery?

I'm curious, and I apologize if this has been answered already, but I noticed something when I checked my VIN @ bmwvin.com. My car has the option code S823A, "Hot-Climate Version."

My initial, and hopeful, thought was that cars with this option would have more robust cooling systems and perhaps water pumps that may last longer or that the other cooling components, if upgraded, would somehow work better in such a way that would put less stress on the water pump. That said though, I'd be surprised if someone in this thread with a failed water pump DIDN'T have this option. Perhaps though cars with this option may have their water pumps last longer?

Some speculation I found via Google/Bing University:
http://www.bmw-sg.com/forums/bmw-3-s...version-3.html (it's an oooold thread from a Singapore BMW enthusiast forum):

Just got a call from my CSA to explain to me on the Hot Climate Version. Hot climate version of our cars, as explained by the CSA, consists of using different materials & parts. More robust oil coolers, air-con units, hoses, pipes, liquids. Too bad he doesn't have a specific list of parts that are different than the BMWs made for the Western Hemisphere.

However, he told me that when PML places orders for their cars to BMW.AG, they are automatically selected with the Hot Climate Version as BMW.AG would ensure that cars coming here would be climatised. He is unsure of PI-ed cars though.

He also mentioned, like Yendor, that BMW cars have different "packages" like Hard Terrain version (different suspension and rims/tires) and Poor Fuel version (cars are de-tuned/tuned to take 91 and below).

http://www.bimmerfest.com/forums/arc...t-111217.html:

the content of SA 858 varies from engine to engine but generally said
you have a modified knock control to avoid a knocking of the engine due
to low fuel quality. With the SA 823 you have a modified cooling
control to avoid critical situations for the engine concerning
overheating. With those options the cars have slightly higher fuel consumption and slightly less power but usually the difference won't be noticed by the customer. Therefore there won't be problems with knocking or overheating
engines.

Then there is this rather recent thread from the 335i folks on this very site, http://www.e90post.com/forums/showthread.php?t=690543:

Hot country refers to a coding option for the IHKA (HVAC computer) that sends more air to the center vents to provide the most a/c cooling. The coding option for hot country is to set it to "normal" so I would assume it's pretty common.

Looks like responses range from HVAC only, to engine coding, to more robust components. I thought I read somewhere too that all US-spec BMWs get it by default, so that could render my theory/speculation irrelevant.

Does anyone have a definitive answer? I'm curious to know, especially if it helps provide more clarity on the water pump thing.

Edit: Just another thought, how many of you here would say you let your car idle for at least 10ish seconds just after starting the car and then after stopping/parking? The thought with this being that as you start the car, you kind of let all of the fluids circulate a bit after sitting for a while and then as you stop, you let the car idle for a bit to cycle hot fluids through and let them cool at least slightly before you shut it all down. I'm not saying that I know this helps in any way, but I'm just throwing ideas out there, anything that might help (even if it sounds outrageous).

They need an S-NJroads version which will swap in the Raptor suspension so you can handle the "crater/pothole maintained roads of NJ" I'd buy that for $1

wp died at just around 59k miles

[kodathedog]

Just replaced mine at 119k with TS and OFHG.
Symptons: After driving 30min I would park and the low coolant light would go on. Filled the resevour but light continued to go on.
When I pulled the pump, bits of gasket were on the impellor blades of the WP

[Hisho335i]

Guys,
I do appreciate your input, i have 335i 07 my water pump died at 82k replaced after that my blower unit inside doesn't work. I did read most articles on this but my problem is i took out the glove box and measured the volt coming to blower is zero, so thats take the probability of blower motor or FSU. any suggestions ??

You probably should create a new thread, this is for tracking Failed/Not Failed? Hopefully people do PM you an answer to your question tho.

[CrazyNole21]

07 here still working at 53k miles. Slight oil leak, maybe from turbos, or one of gaskets. Hopefully when I bring in my car for that battery recall, they can take a look at my turbos to see if they need to be replaced under warranty.

You cant qoute me on that but I believe the 335 does have different pump then 330's and below.

Like others mentioned if it is the same one, which it might be but I dont think so personally then higher failure rate could be due to higher temp that the 335 causes or the speed it has to operate at to keep the temp in check.

330's and below E90's have failure rate in the 140-160k range maybe more there isnt many people that have that many miles yet maybe only 2-3 people I know of here are in that mile range.
Im at 107k with no failure yet, unless I plan long road trip I wont change it either I want to see how many I get for sake of the forum.

[tys90]

84k and still going. However, I'm getting the cooling thermostat code so I wouldn't be surprised if my water pump is on it's last legs. I think I'm going to proactively replace it.

[Eddien123]

Died at 67

[Mr.RT]

Taking it in this week. Died at 66k.

[BMW Lawman]

Yellow warning light, and ten seconds later the red warning light along with the AC stopped working. Pulled over and there was a some coolant boiling out of the recovery/fill tank and the fan was running full speed and really loud. Let it sit for 15 minutes, started it up and no issues. Drove it 10 miles to the dealership with no issues, and that's where it sits as I type this. Gonna see what they quote for repair, they were closed when I dropped it off. There's a highly rated independent shop nearby that will surely beat the stealerships high prices.

[TitanLH8]

kind of feel uneasy knowing that this will eventually happen one day to my car :/

currently at 75k on original pump (knock on wood)

Me too, but I am at 106k miles on original water pump and thermostat...

[norsairius]

Sorry if bringing up this week-old thread offends anyone, but I did some research that may bring some hope to those of us driving later-model 328s.

I've been doing some extensive searching and reading on this and came up with the following info.

First, this post (from this thread: http://www.e90post.com/forums/showth...t=11517586925):

#11517586925 325i/330i 2004-2007; 328i 2006-2012
So, sounds like there's 3 water pump models. Not sure if it's due to failures and if they addressed the issue.

I searched the last two part numbers listed on Google and found these pages:
Part #11517563183: http://parts.bmwofsouthatlanta.com/p...517563183.html
Part #11517586925: http://parts.bmwofsouthatlanta.com/p...517586925.html

If you take a look at the product application notes, for the older part number (ending in 3183), it looks like this part was used on cars up to 7/2008. I would guess that means cars built up until that point. The newer part number just lists a bunch of BMW models with non-turbo I6 engines. If you click through the "Waterpump-Thermostat" link in the product application section, it looks like you just get a list of supporting parts needed. You'll notice that a few water pumps are listed, but the same notes on the date are there when you click "More Details" (http://parts.bmwofsouthatlanta.com/s...roduct=1271140).

I'm not sure if there's a good way to tell what model years exactly used which part# water pump and I couldn't find where accel got their information. Can anyone else shed light on this maybe?

So would this be any indication that 328s built after 7/2008 have the newest water pump part# installed? Feel free to tell me if I'm completely off base. My information sources may not necessarily be the best, but I'm just trying to think of any theories or ideas here that could help give some of us more peace of mind, especially since many of us use these cars as daily drivers and for the occasional long distance road trip.

Would've cost me more to tow it up to surrey even if it were that cheap.
