Couple of days ago my 09 e90 showed service due light. My current milage is 39000 miles. I checked the control and it was due in for oil service. My warranty ended last year and it was going to be my first out of warranty service so I didn't know what to expect. I knew they were going to overcharge but I thought how much more expensive could it be... dealer was on my way to work and I didn't feel like searching for a shop to do an oil change. Also with a loaner I thought it would save a lot of hassle.

So I SA gave me a run down of the services that were due and the price.
I was shocked.
For oil service I was quoted $440.27.
Intake silencer $199.28
and Fuel Service which is included in oil service I guess.
Total coming out to $649.95

I asked what this oil service included and why it was so expensive and he said it was an oil change and it was expensive because M3 oils are different.
I was so outraged I forgot to ask what the intake silencer was for and what this fuel service was for...

What are the services that are normally due at 40k miles? Is there anything special being done that warrants this kind of price? What am i missing?

Any advice and information would be much appreciated.
