2004 BMW 745Li computer problems: DSC inactive, transmission failsafe, etc.?

Question

I have a 04 745Li and the computer says the service is overdue 2000 miles, when in fact ive had most the servicing done, just didnt get the computer reset because the guy didnt have the proper equipment.
When I first start the car in the morning, it sometimes sputters for a second, then the computer goes whack: the nav screen breifly turns off then back on, then im informed that Dynamic Stability Control is turned off, sometimes the transmission goes into "failsafe mode", and other times it does a combination and also says parking brake/brak malfunction. However, when the car is warmed up, i turn it off then back on it runs perfectly like nothing ever happened.
My cousin says it could be a misread by the computers due to a cracked hose, or it could possibly be the fuel injectors. Any other ideas? will resetting the computer maybe stop all these problems? any insight appreciated, thanks

cant really afford to take it to the dealership, theyre gonna charge 1k+ just to hook it up to the CPU, and if they fix anything, it will be at least 2-3,000$

Answer 1

That car is way too complicated to be taking to some shade tree mechanic for service. You're the kind of person that used to give us dealership people a real headache -- you can afford to buy the car, just can't afford to keep it. If you can't get it serviced by properly trained people with proper equipment, then sell it and buy something you can manage.

Answer 2

I had come to a stop , than accelerated and made a u turn ater completing the turn my brake light came on , than other warning lights came on. I drove it home less than 1/4 mile and tried to put it into park and it will not go in park.

Answer 3

You are going to have to the car into the dealer. Extremely complex ed and only the dealer has the ability to update replaced control modules.

Answer 4

I would take back to the dealership and let them check it over.
