Hi, welcome to Just Answers,
Sorry about the spelling, I typed that while my kids were at Chucky Cheese, for a new year birthday party. I'll opt out of the question so you can get some opinions from other BMW techs here.
PS, I only counted (4) misspelled and (1) not capitalized...I never put down in my profile I was a perfect typer/speller.
You hasn't offended me, nor do I want you to pay unless your completely satisfied..this is *bullshit* on Carmax's part and you should at least ask them for the damaged parts after the job is over, if the belt tore off you'll know if it was worn and had done that; also a crack in the reservoir will be different than a damaged reservoir. This post will still stay open for other techs to provide an opinion as well. And if you have any questions while it's still there, I'd be happy to help.
But I am going to use the Spell Check box more often ;)
