So car went to the body shop, and somehow gained 200 miles and misfires now and a few codes.
The car went in for left front fender scratch they painted it off the car, also changed steering angle sensor, and driver door controls not working was a fuse from short in the mirror.
Now the car is misfiring all cylinders codes are 2b35-39 2b3a-e 2b41 combustion misfire with cut
then there's these codes
2b57 safety concept manager action?
2796 safety concept manager action?
27c1 info tank empty on fault entry
27cf building up of fuel pressure fuel pump feed
2b49 combustion misfire with emissions deterioration cylinder 8
car has 93k miles 2008 m5

2b57 and 2796 anyone have anymore info on these and ides where i should start looking?

The spark plugs are due but i just changed number 7 plug and the injector two months ago because of a misfire. I don't have a dealer near me, so at the time i tired a Autolite. it made the misfire worse lol ordered the ngk and cured my problem. but even now cylinder 7 is misfiring. They told me they put gas in it could cheap gas be the problem?

I wouldn't drive the car again (if that is an option) until you get this sorted out. No reason for them to put 200 miles on it - consider filing a police report. If it's not theft, it certainly sounds like someone drove your car like they stole it. Either way, I'd be considering a lawsuit.

Reminds me of the technician at a BMW dealer in TX that wrecked a board member's M5 - huge headache, but it worked out for him eventually.

prior to filing a police report look at the fine print of the work order you signed

Also must read post # 1847:

Excellent advice in post # 1847:

"Lessons learned...Use an indy shop if you can and always state "not authorized to test drive without me in the car" on the service slip when signing the release to do the work. Protect yourself."

Also note reference to BMW technician hiring practices, very low bar indeed.

It is disheartening to note that BMW dealerships would rather spend money on retaining a crack legal team than invest their HR/PR/Customer relations departments.

Many successful companies have very robust, competent, fully empowered HR departments that are allowed to provide benefits and training in order to retain the best or at least the top 10%.
An investment that pays dividends to the Brand in the long term.

Not only BMW it goes for the majority of dealerships, a race to the bottom with employing low wage grease monkeys to do work beyond their training.
My experience on my 2007 Tundra LTD when still fairly new a technical service bulletin was botched by tech name Zach, his employee placard profile had no noteworthy certifications except for nick name "Zack Attack". LOL

Dealer would not take accountability for required rework of service bulletin repair instead quoted me $900.00+
Never been to Dealer since for any of my cars since.
If one cannot trust Toyota who else can be trustworthy.
