**HELP

Hello Everyone,

Recently I was up near the rev limiter ~ 8K and my car lit up like a Christmas tree - traction control, service engine soon, battery, yellow engine light, etc.

I took my 08 M3 w/ 29K miles to the dealer. After a few days all they did was reset the codes and test drive the car. Nothing came back on in about 50 miles of driving, but I am not convinced that all it needs is a reset...

Here are the codes they pulled:

A834 GWS: Supply voltage too low
9CB5 FRM: Battery Exhausted
5E19 DSC: Engine management: interface
2B26 DME: Throttle Valve monitoring, bank 2
2B28 DME Throttle Valves, test of return springs, bank 2
2B5C DME: Throttle valves fault status, bank 2
2B41 DME: Misfire with cutout, several cylinders, 8, 7, 6,5,4,3,2,1
CF24 Message error status DCS
CF1D Message (wheel pressure)
CF1E Message (wheel circumferntial velocity)
CF17 Message (torque request DSC)
CF1B Message steering wheel angle
CF18 Message speed
A125 CAS: incorrect or implausible signal from engine management

So here is explanation my SA and tech gave me, which just isn't sitting right with me:

'Cleared faults. Motor binding from vehicle sitting. Recommend to drive vehicle at various driving conditions to actuate full range of throttler motors'

Like i said, all they did was reset the codes and currently there are no lights on... but there must have been something that caused this. Could it be an electrical problem?

Any help is greatly appreciated guys. Thanks in advanced

I've never heard of so many codes at once that wasn't related to a DME fault. You may want to PM one of the tuners here. How often is the car driven?

Ok thanks... Who are some of the tuners on here who I should ask?

I actually just purchased it a week ago so I am not sure exactly how it was treated before but with only 28k miles over 5 years I am guessing it wasn't driven very much

That is a lot of codes. Funny that it only lists bank 2 for the Throttle Valve Actuator yet all cylinders were misfiring....so why not bank 1 Throttle Actuator. And when my Throttle Valve Actuators went, I didn't get any of those other codes.

A tuner you could contact is Mike Benvo at BPMotorsports. There are others as well so for a reviews, go to the vendor review section under the classifieds.

Hope you figure this out!
