what were your "issues" that they needed to have the scanner on your car? They wouldn't have it hooked up for an oil change.
1. The A1 service code (oil change & tire rotation).
2. The rev hang issue.
3. Oil usage (2.25 qt over 7000 miles. See my update in the "burn oil" thread).
4. Intermittent inability for people to understand me over the hands-free when I'm talking on the phone. They can hear me, they just can't understand me. (Car's fine they say, and directed me to handsfreelink.com to see if my phone is fully compatible with the car system.)
5. Rattling interior fan/blower at low speeds. (Which they're going to replace as soon as the one they had to order shows up.)
I think he said it was hooked up to investigate the rev hang and the bluetooth/phone issue. He said that the tech has an incentive to download updates when they find them because they get paid 0.3 hours for each one. He also said that they could tell what my peak rpm had been when they were hooked up to the computer and (I think) that they expect the rev hang to vary based on engine temperature and rpm. He was pretty adamant about the fact that they'd been querying the computer and didn't see any updates for my car.
So I want to believe him because, well, I guess I just expect people to be competent at their jobs and he did give me some good information that aligned with what I'm reading on this forum. (Like working with me on the oil usage instead of blowing me off and telling me that installing a turbo won't void my warranty.

So I walk away thinking that everything he said sounds reasonable and makes sense but doesn't gibe with the collective knowledge on this forum and/or my own past experience. So, who knows, maybe this is a staged rollout across the US, too, and they'll have it when I go back for my next service and complain about the rev hang again.
