Firstly, I assume the codes have been verified at a BMW dealership? From my experience that is the only way to get a true diagnosis; codes read by a generally available scanner and/or at Auto Zone etc. will not give a true picture of the problem and can send you off on a wild goose chase. I can offer a suggestion concerning the P1092 code. If you had it read at AutoZone (like I did) the first place to look is the O2 sensor for bank 2. For my X5 this was a read herring as the 'running lean' indicator is just a symptom not a root cause. Cutting a long story short, the most common underlying root cause of this code is a vacuum leak and in my case the leak was found in the oddest of places, i.e. the "O" ring was split where the dip-stick tube enters the crank case. $300 later and my SES light remains off but at least I did't have to worry about replacing the O2 sensors.

Hope this helps.
