Replace Computer?

[Sterling 4.4]

My 2006 4.4 X has been in the shop now for 13 days. It all started when my left headlight went out. I took it in and they "fixed" it by replacing the controller. This took 4 days. The next day on the way to work, I notice my adaptive headlights aren't turning. I then noticed I don't get the friendly wink of the headlights upon starting up the car. I take it back that day and kindly let them know they didn't fix my problem. After 5 more days, they replaced a faulty wire and it was fixed again. Over the weekend, my check control comes on and says check the lowbeam. Now the right headlight is out. I took it back and it has been there for 3 days.

They say they can't get the program to "take" and they have been in contact with BMW. Today they call and say they have to replace the computer it it should be here in 3-4 days.

Very painful set of events and I get watch my monthly payment fly out the window while I drive a 325 with vinyl seats. Oh yeah, I put three coats of Zaino on it the day before it went in 2+ weeks ago and I am missing out on that too!

Anybody had an issue like this? From talking to the dealer, this is the first time this has ever happened.
