is there any way to fix it

2003 540i bought the car as a theft recovery with the computer under the glove box missing. bought a new computer from the BMW dealer and they installed it but not much works it will default start by holding the key in the start position for several seconds and it drives and shifts great. however no windows, no speedo,no tach, no dash, no nav screen,no climate control, no radio, . Dealer say they cannot fix it without access to the old computer. local independent BMW shop tried but gave up. the air bag warning light is always on even when the key is removed and the battery will slowly drain if left connected

The General Module is behind the GB, is that what you are talking about?
Was it coded?
The engine computer is the DME and under the hood.

Are you looking to fix this yourself, or looking for someone who can do it?

Dealers simply don't want to futz with boogered-up cars. Your best bet is to find a savvy BMW indie.

Although, I'm surprised that, since they sold you the part, they have not taken responsibility to make it work.

it must be the general module that was replaced and I assume it was not coded as the dealer rep said he needed to original unit to transfer the data to the new unit. i have exhausted the local indie and he said it was a can bus issue so i am forced to try to fix it myself i am open to any suggestions

what would cause a failure of almost all the systems, when the key is turned on to start nothing happens for several seconds then it cranks and starts, throttle response is OK, center lcd display is mostly blank with six or so small unreadable characters in the upper left corner. temp gauge goes immediately to max, no tach reading, fuel gauge inconsistent. no readings in center console. radio in-op, no a/c or heat, windows will not open, presently in closed position. car drives ok but no speedometer, no head lights. Interior lights ok could it be that the dealer installed an uncoded general module at $500 plus labor. should i try a used general module from a 540

The General Module MUST be coded to the car. Good Luck.
