N52 pumps die from the electronic being exposed to heat cycling (possibly an after-effect of the higher quality metal enclosure). On mine the pump was still working fine mechanically but the electronic was completely fried with burn marks on the edge of the PCB.

I have a late build 2011 328i xdrive and I was on the original working water pump and thermostat till 145,000 miles.. it had zero issues but felt It was definitely necessary to change it out with a new setup. One thing I was big on was changing out the coolant like every 50k miles with BMW oem blue. I took the old pump apart to see how it looked inside and to my surprise it looked clean and brand new still and no burning smell.

It's just by the time we get good alternative for them to last longer the car will start to become obsolete. Like we're 2018 now and it's 5 years after the last production year model. Still nothing. 11 years for 07s.y Now if they come out with something better and cheaper that might be interested. When are they going to come out, 15, 20 years? |

For the N52, below are the superseded part numbers and their effective dates.
My 2006 E90 325i (4/2006 build) pump failed at 149,521 miles in July 2011. Since then in the 7 ensuing years past the replacement date, the replaced pump has gone 210,000 miles. No codes have been present anytime I've scanned the car over the years. The P/N of the pump I ordered in July 2011 is 11517586925 which is the current pump design from 4/2008 forward. I've been driving the same commute the entire time. So just to jinx myself, the pump in my '08 Z4 3.0si Coupe (11/2007 build) now at 11 years old and 92,000 miles has yet to throw a pump code.

If you plan on keeping your car long term, then save money for such things as a valvecover gasket replacement and oil filter housing gasket replacement, both which can leak oil onto the serpentine belt, which if it breaks CAN leave the car stranded and with expensive repair bills. And plan on a serpentine tensioner replacement, as that can result in engine damage as well. If you are OCD about leaks, then you'll eventually need to replace the oil pan gasket. Unless you live in a major city with shitty pothole-filled roads like NYC or Philly, the suspension and suspension bushings last far longer than people think. IMO, many people here replace shocks, struts, and bushings way too early. Save maintenance money for stuff that breaks, not for stuff you think may break because you read about it on the internet. Doubling up of maintenance (i.e. halving the intervals) does not increase the car's service life by double. I know this from experience. I've owned my car for over 12 years since I took delivery at 3 miles on the odometer (I ordered my car) and it now is about to pass 360,000 miles the week after next. I do most all my own maintenance and repairs. My 2 cents.

I have a 2013 E92 with an N55. Just replaced the water pump last month @ 47K miles. It didn't die completely but started to flake out, as in overheated limp mode about 20 miles after cold start. Stop/restart fixed the immediate problem, but replacement was needed to restore driver confidence. At least I was prepared to have it go out this early, thanks to the info I have gleaned from reading posts on this board.

I have a 2010 model year 2009 built date e90 with N54. I am at 115k miles and water pump has not failed yet under my ownership. Looking through the carfax, I did not see any history of replacing it. My guess is that it was done in the earlier years of the car and not documented, or I am hanging on by a thread.

I think Miller applies his position of some BMW engines having substandard cooling system components to the E90 (like the M62 for example). For the N52, the cooling system in my experience is on the level of robustness as the E30 had. While the idea is great, I think the electric water pump engineering BMW executed is stupid. With no coolant temp gauge in the N52 E90, there is no way to tell the WP is not operating to spec until it goes tits up. Maybe following Miller's maintenance schedule will increase an E90's longevity, but at the level of mileage I've achieved on the CBS schedule, I can't see how much farther it would go and especially for the average owner, including BMW enthusiasts, where it is rare they keep a car past 150,000 to 200,000 miles. Not many people keep cars past 250,000 mile unless they are serious DIY'ers, because it's just not immediately-appearing cost effective at Dealer and BMW specialist Indy prices. To be transparent with my E90, I keep running it because I like the simplicity and directness of it; and I'm very well set up to DIY it. I have no desire for iDrive (which EVERY frickin' car has now) and a rear-drive manual transmission drivetrain sports sedan, which NO sports sedan offers anymore. The new G30 has not manual option, so no thanks BMW. My 2 cents.

The original water pump on my 2006 325xi went out at 72k miles, the replacement has been fine as of 142k. It also cracked the lower radiator hose where the sensor mounts around 120k, dumping a lot of the coolant. My 2009 328i with 35,000 miles has a coolant hose that has heat damage on the outside and I plan on replacing it.
While a lot of people over-maintain these cars with the Mike Miller aircraft maintenance schedule, I do feel opening the hood and at least looking at the condition of hoses, looking for leaks, etc will save an owner a lot of headaches. I open my hoods once a week, and look over everything before a long trip. My 325 has been very reliable, but the parts that have failed did fail long before 150k miles. I wouldn't describe my driving as severe, and my vehicles are garage stored most of the time. Time and heat cycles seem to have more of an impact on gaskets and cooling system parts over mileage.
