I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.
I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.
Thanks Fixya and all contributors

You are in the Ballpark. It will cost you several Hundred to fix. Will prob have to have the module replaced. Go to a trusted European repair placed. DO NOT TAKE TO DEALERunless you want to give them the car. They are very happy with $$$$$$$$ You can fix for alot less than dealer. Good luck.

If you have SRS and "brake failure" it should be taken to a dealer. a shadetree mechanic will screw more up than he will fix in this case. trust me on this! you will pay a price, but will save you more $ and less headache in the longrun.

just unhook the battery for about 20 minutes. if you have an anti-theft radio make sure you know the code and how to enter it.
SOURCE: How do I reset the SRS-Airbag SERVICE URGENT Fault
Here's a quick check list
for most common cost of SRS / Air bag problem.
Dirty contacts on driver
and passenger seat belt buckles
Dirty contacts on seat belt connectors
(under seats)
Dirty contacts on driver and passenger sides weight
sensors (under seat)
Seat covers
Weight on passenger seat
(Example:
grocery package trigger SRS / Air Bag light on the way home.)
I
recommend you to pass an vacuum over the contacts and use CRC
electronic parts cleaner to rule out connectivity problem.
I DO NOT
recommend disconnecting the negative battery connector to clean the code(s).
Without the code(s) the dealer will takes "BILLABLE" time to reproduce
the problem.
