I bought a 2003 X5 4.4 with 32,600 miles in October, 2012.

We also have a M3 convert, and a 7er on top of many other Bimmers over the years.

The 7er's rear passenger window regulator broke in August, so I replaced it. Then the E53 rear passenger side window regulator broke in September, so I replaced it. Then the E53 front passenger window regulator broke in October, so I replaced it. Then E53 front driver window regulator broke in November, so I replaced it. Three days ago, the E53 rear driver side window regulator broke, so I replaced it....... get the picture?!?

BMW knew they have a POS design so they finally changed it after five years.

I pinged them with my VINs and twenty five year ownership history of nine BMWs. "Tough shiesse!" was their answer.

I planned on buying a new 7er Alpina BMW next next year, but changed my mind. Merc, Jag or ? instead of BMW for me here on out. BMW doesn't give a shiesse about their customers. Look elsewhere for better customer care.

On the E53 do yourself a favor and solder in a foot of additional interior door handle lighting wiring to make the inevitable interior panel replacement easier on your second or third replacement of the rotten regulator.
