As for window regulators, my X has yet to have a failure.

CCV has yet to be an issue too!

110,000k one boot no window regulators

Tiag, CCV is an M54 issue, not for the V8's as much

[TiAgX5]

Never had an issue on the '05 E46 330i in over 140k miles. Not even a removal/cleaning.

Trader4,

Volvo's I5s are riddled with oil seperator issues. And those are a total PITA to get to. I never want to do one again, but most likely will have to. Audis system on their 1.8t also has some issues but aren't as nearly as critical as Volvos or BMWs.

As far as CV boots go, I have replaced them Audis, Volkswagens, Volvos, and Subarus.

Window regulators are also a plague in the VW/Audi world.

So it isn't just BMWs. It is cars in general.

The locations where the X is operated has a lot to do with many of the problems that people are experiencing. Both of you guys live in Texas which I wouldn't call a rust belt state. You winter is not as harsh as people living in Canada or further North.

Temperature extreme affects the properties of material. Rubber items such as CV boots can crack when the temp drop below 0F.

You are correct, we don't have to worry about corrosion or harsh winters. On the other hand further North the summer temperatures are much cooler. Our Texas summers are in the 90s in June and the rest of the summer temperatures are often over 100. And Summer temperatures last longer. The forecast is 90 for the next week. The comparison may not equal out but Texas has extremes as well.

Does it cool off quiet a bit at night? I vaguely remember from my brief time in Houston that during the day it was damn hot, and at night it got pretty chilly. If so, I think temperature cycles like that can fatigue plastics and rubbers cant it?

Yes, cycles will accelerate failure. I don't recall a chilly summer night. My guess the summer high/low varies 20-25 degrees and in the winter 25-30.

It certainly seems the E53 design/materals perform better in hot climates.

I've towed a 6k lb trailer and seen the OBC outside temp showing over 120 deg F, stop and go hwy construction traffic, with the AC on max. The X performs flawless in those conditions.

But when engine parts goes from 0F from sitting all night in the Polar Vortex to 200F operating temp in the winter you can bet that this type of extreme temp is more damaging to the material. Most Intermediate lever problems are experience by owners that lives in the colder climates such as the Northern part of the states or Canada.
