Found this on Bimmerfest...maybe it will give a clue:

Terminal Resistors: are used in the CAN bus circuit to establish the correct impedance to ensure fault free communication. A 120 Ohm resistor is installed in two control units of the CAN between CAN-H and CAN-L. Because the CAN is a parallel circuit, the effective resistance of the complete circuit is 60 Ohms. On some vehicles there is a jumper wire that connects the two parallel branches together, others have an internal connection at the instrument cluster.
The resistance is measured by connecting the appropriate adapter to any of the modules on the CAN and measuring the resistance between CAN-L and CAN-H. The resistance should be 60 Ohms. The CAN bus is very stable and can continue to communicate if the resistance on the CAN bus is not completely correct; however, sporadic communication faults will occur.
The terminal resistors are located in the ASC/DSC control unit and either the instrument cluster or in the DME.

The wire color of the CAN bus is uniform throughout the vehicle with: CAN-Low GE/BR and CAN-High GE/SW or GE/RT. Shielded wiring is easily identified by the black sheath surrounding the CAN bus.

andrewwynn will become famous soon enough
That's good feedback but also; in every sub module in the foxwell it will show the part number it's controlling. The "reset" may not be for the item (resistor) but to tell the computer it's been replaced.

Thanks I'll check it out

I hadn't thought about that.

Damn I'm getting old...

Update....

Still having the 5088 code without rhyme or reason.

Sometimes failsafe after driving when put into Park.

Sometimes while driving...

Sometimes immediately after resetting just putting it into drive kicks off

These other symptoms seem to be something additional I think.

Can you easily access a newer shifter over there?

I've replaced it twice both used realoem.com shows it's around $500 USD but here it's $1320 USD.

Another update.....

Interlock cable is shit, replacing today and hopefully that will quit tripping the failsafe resistor (transistor)
