My comment above about not knowing how to reset the OBC got me searching and I should have known that Google was your friend. Here's a video for the E90 on how to do it for those that like DIY.
$95.00 here in Texas, no doubt it can be done for less, but the "Bee" gets to see the dealer twice a year until the warranty expires.
Only $90 at the local dealer here. Well worth it to not lay on the ground in a cold garage in the winter.
Bah, you guys are all amateurs. You want to pay hundreds of dollars for a dealer oil change, then you need to go to Porsche. There is no substitute...
Actually, oil changes at the Porsche dealer for my 911 are significantly less expensive than my M3. In fact, I'd go as far to say that my 911 is more reliable and a lot less expensive to maintain than my M3. When I bought my M3 I figured that it wouldn't be any worse in terms of ownership cost than my 911, but boy was a wrong.
