Was talking about this the other day with a friend. The "lifetime" design aspect is based around how a car would be driven over in Europe. North America is really the only place where you will see older, super high mileage cars (ie. the 1995 740i w/ 165K I worked on today).
Gas is super expensive, taxes are high, etc., etc. so they have fewer miles put on them and the "lifetime" parts may just last a lifetime there --- simply because the miles are low. Here, on the other hand, cars are driven every single day in stop/go traffic, short trips, varying speeds, high temps, low temps... whatever.... all the time and anytime thus requiring more maintenance.
PLus, don't forget their job IS to SELL you cars....
OP -- you find the problem yet?
Oh, no! :yikes: Another "lifetime" filter... I guess Europeans must have very short lifespans... :tsk:
