another m3 with engine malfunction, DSC, FTM, emissions errors

i was running errands on friday and all of a sudden a whole bunch of errors popped up

-engine malfunction-reduced power
-dsc malfunction
-ftm malfunction
-increased emissions

what a way to ruin the weekend. I've booked the dealer for a tuesday appointment.

my 08 m3 is stock with 76k km on it. just great when the warranty runs out at the end of june 2012, good thing i have extended warranty on it.

looks like its either the throttle valve actuator or the idle control valve issue that have been discussed before. probably also needs a software update

after a restart i only get the CEL error warning of increased emissions. But after another restart all the other errors pop up again

I don't have tools to pull the codes, i'll have to leave it to the dealer to do it

My 2008 was like that when the idle valve went.

Good luck but you Mage gain 20HP with a software update!

Sounds like battery! Same thing happened to me. IBS cable failed draining my battery then throwing bunch of nonsense codes. Replaced cable and battery under warranty. Everything back to normal. I hope my experience helps. Good luck.

diagnosis came back from the dealer-Throttle actuators need replacing. 2-3 week delay due to back orders
