Have 2007 bmwx3 with low mileage
In July 2012 had a new fuel pump. In sept 2012 had a new turbo. The dde light comes on intermittently and am now being told I need 4 new injectors?
Was there a problem with year model and any ideas of an alternative solution

Not under warranty? BMW Bring My Wallet.

There are 874 Technical Service Bulletins for that year. Does that tell you anything about reliability?

I'm skeptical, unless you have only taken it to BMW for servicing.
