^That's A LOT of miles on your original pump. Typical failure of water pump on m54 at the shop was ~120,000 miles give or take 15,000 miles.

Color me impressed. I'm curious about the Overflow tank replace. Is thar normal or something you picked up?

It's good practice. The tank is fairly inexpensive and can crack/leak at really early mileages sometimes.

Had it happen to an e36 I sold. We used to see it all the time at the shop too. Usually accompanied by a bad head gasket because the owner didn't want to tow the vehicle in and instead drove it and overheated it (like the e36 I mentioned). :dunno:

The engineers at BMW would have made certain material selection decisions based on the type of antifreeze. I don't feel it is necessary or very valuable to second guess that. Even with frequent changes (every two years) you are talking an extra $10 a year. Lost in the rounding error for my overall BMW costs...

For those of you with pets, the BMW stuff is still poisonous but has a powerful embittering agent added to dissuade pets to drink it. I got a tiny drop splashed on my lip and tasted that !&$! for two days.

regulator, another example of crap that BMW produces. This is the
fourth one now. At least this time it didn't break the glass like it
did two previous times. Funny, they work in MB to Toyotas, but BMW
can't figure out how to make expansion tanks or window regulators.

As long as they can figure out suspensions and drivetrains I'm happy. I can deal with regular failure/maintenance items if I get to enjoy the BMW ownership experience. Haven't driven an MB or Toyota yet that I wanted to own for more than a week.

But yes, some of their parts do fail more often than other manufacturers' versions of those same parts. :dunno:

Sucks that your windows keep breaking though... I've replaced 5 or 6 regulators now and never had a broken window. Replaced them in other marques too btw... Acura Integra for one.

I was caught by surprise when my first one cracked and gave the engine compartment a lovely shower during a Dallas interstate traffic jam on a 100 degree day. That was before I joined the forum though and I would like to say I've now learned from other members' experience. So now I replace it on schedule no matter what, and also make sure not to overfill the cooling system.
