I have to keep my ASS
I had my car in for software updates/recalls and told them to do the ASS coding too. The service advisor said they couldn't do it. I said, "Yes, you can".
A tech who was walking by overheard us and said, "We could, but we're not allowed to on any more cars". He said that BMW NA has done too many and it was affecting their (and I'm foggy on what agency or program he referred to) EPA rebate, or something similar.
I have to say it made sense. If you're BMW and you claim a car model gets a certain MPG and emits a certain amount of smog, you can't then disable a system that contributes to those numbers.
I may look into get it done some other way.
