modulemaster's website made the comment that if the car operates normally and then the lights come on and the speedo goes it is temperature related.

Mine works fine until it comes up to temp, maybe 10 minutes. Then speedo goes and lights come on. It seems if it were a bad sensor this wouldn't be the case.

What I don't know is BMW control logic. It must be polling devices on some regular basis at some pre determined interval. If they fault once some circuits need to be cleared, like oil change interval. In my case I'm just wondering if there had been a transitory fault it has been stored in the computer and will keep showing lights until it is cleared. Then I wonder if nothing is wrong, just the fault circuit.

At my mileage I don't really care about ABS. I have a GPS so I know my speed anyways without a Speedometer......just kinda annoying when stuff doesn't work. To show my mentality when my check engine light came on years ago I did the gas cap thing and in the end put a piece of black electrical tape over it. Ditto when the airbag warning light started to come on intermittently........more black tape........may have to get it out again!

I like the BMW ride, but I do think the complexity of their electronics and their propensity to fail after 100,000 miles really detracts from the vehicle. The motor and transmission have been bullet proof other than all the oil gaskets that had to be replaced.
