Peake Code 6b - Pre-drive check of drive-by-wire system - The Unofficial BMW M5 Messageboard (m5board.com)

VetteRacer · 24th February 2009, 00:57

I went to start my car to head to work today and have an indecipherable warning on my dash (dead pixels). Car is in limp mode, cant gas it and cant bring RPMs up. Peake tells me 6b. I have had this 2 times in the past, let car sit for 5-10 minutes and it then works fine.
Any ideas on what might be causing this? Seems to have happened after leaving car sit in garage most of weekend.
I am off to try to start it again, crossing my fingers that it works, as I don't have alternate transportation to work right now..

If anyone has any ideas what might be causing this intermittent problem please let me know!

see my thread "car will only run on sunoco 93"

i had this issue along with others. My car would refuse to rev go into failsafe mode every day. I replaced the tps sensors both and the car totally transformed it was like a new car.

Aside from that i replaced fule, air, spark, maf, as maintenance i have 140k on my car. The tps issue plagued me for over a year before i figured it out hope this helps

(on a side note reason it took so long is because i paid the dealer $670 to replace the TPS....they did not don't know what they did beside ripp me off. That is why it took so long because i though of the tps as my last problem) The part has been updated...i posted the part numbers in my other thread...
