Go to Costco or local Harbor Freight tools and get OBD2 or OBDII sensor:

Costco has one for $30 I think.
Plug it into your OBDII port to check the P Codes.
The code will give you an idea of what problem you have before handing $100 "diag" fee to dealer.

Have a look at this SIB... Sounds very familiar, although technically it's only supposed to apply to 2003/2004 cars:
SIB 11 03 06
There's a 'repair kit' for the work in this SIB which is less than $20 per side I think.

My Ride: 2005 545i
I had the same error message with check engine light staying lit, on my 05 545i. Per my invoice, the fault code was 2EF4 [T-SAT MECHANISM STUCKED] It turned out to be the thermostat was sticking in the open position so they replaced it. Yours maybe a different issue as there can multiple increased emissions light along with check engine faults.

Let me clarify that last statement. When the check engine light and message came on I drove the car for 3-4 days until I could get it in for a service. During that period only abnormal issue I noticed was the engine idled slightly rougher a few times. Now, I don't like driving with warning lights on so maybe I was being over sensitive to any slight difference in the car's behavior. I mentioned this to my SA and he said the V8 can idle rough periodically and it was not a problem.

I think I also experience rougher idle but it may be due to my imagination
