When mine started acting up with the program error , it was always during
startup and it was usually only the first start in the morning when everything was cold. In my case i cleaned the contacts on the shifter and treated with stabilant22a , that didn't get rid of the problem, then i pulled the trans control module, took it apart and looked at the circuit board. It had the usual poor german solder joints that has visible cracking where the relay was fastened in the center of the board. Resoldered bad joints and any others that looked suspect and its been fine ever since.

I'm currently running a log on what occurs before the fault appears, like trying to find a pattern of sorts. whether i blip the throttle during start-up, or when I leave the a/c or radio on before I start, and how many times do I have to restart before the fault would go away.
indy pulled error message on my '93 525ia....
..by hooking up his diag computer to the diag port under the hood... message was "fluid pressure regulator".... that message and a check with the TIS (or whaever listing shows tech bulletins) confirmed also that there was an updated eprom for the tranny. $90 for the pressure regulator and $99 for the eprom (or was it $20) and labor costs later and all's been well for the last 12-14 months....
...check your error codes and yes, you're battery will need to be well up to snuff... good luck. seems any of many, or a combo of things can cause this error.... i had limp mode too.
good luck you can beat it. -Rob.

My mechanic is trying to zero in on the electricals because he thinks some electrical glitches might be causing the error.
Is the check control module responsible for deciphering these faults? I had an e30 once with a check control module that would tell me somethings wrong but really theres none, I fixed the problem by simply unplugging the module. It ran trouble free until I had to sell it reluctantly. Can I do the same for my 525?
