Question Intermittent (Yellow) EML light followed by Traction Control and Brake light

2 or 3 times in the past week the EML light will turn on (yellow) within the first 5 minutes of driving. And then within another minute or two (or coming to stop or driving slowly) the Traction Control light and Brake light will both turn on (yellow) and the car will go into limp mode. I have also had the engine completely shut off after all three lights came on. No stuttering/shuddering/shaking/etc, just nice and quite engine shut off. So I come to a stop, turn the car all the way off, and then it starts right back up again with no lights on and typically the lights won't come back on again for at least a few days to a week.

On one random occasion a few weeks back I was coming to a stop at a stop sign going about 5-10mph and the engine shut off with no lights coming on at all. Once again, no stuttering/shuddering/shaking/etc, just nice and quite engine shut off. It fired right back up again after turning off and back on again.

I had a buddy use carsoft to read codes (and then delete them) on 2 different occasions after the lights have come on. The last time it happened, these were the codes that fired off:
Module: ABS/ASC/DSC
5e19 CAN DME/DDE (what is this? I read somewhere that the description of for this code is "engine torque not adjustable". Could have to do with limp mode?)

Module: DME/DDE
230 (note: no description provided via carsoft)
52 Ignition Fault on Cylinder 2 (note: This error occurred the first time I experienced the issue so I replaced the ignition coil on Cylinder 2 just to be safe, but the error came back anyways.)
171 Fuel Supply System (note: did not see this code the first time the codes were read, but did see a "Fuel Pump" error code stored. However I don't know how long the Fuel Pump error code had been stored because I hadn't had the codes read for a long time)

Module: ZKE/ZVM
7 Module not coded

Module: DME/DDE
137 Knock Sensor 1 (note: did not see this code the first time the codes were read, and could have just been a fluke?)

I have seen a number of threads about EML/Traction/Brake lights and the resolutions in those posts seem to involve the Throttle Position Sensors (TPS) and/or Throttle Pedal sensor. However, I figured I would have at least seen TPS error code if that was the case?

Does anyone have any insight into the codes above and or what to fix/replace?

Thanks!

Re: Intermittent (Yellow) EML light followed by Traction Control and Brake light

I can't relate to any of your codes but my situation was the eml/brake/dsc lights came on simultaneously then car went into limp mode. Once restarted, everything was back to normal. Took it to a shop and they told me I needed a new dsc unit. It turned out one of the wires for one of my wheel speed sensors was damaged.

Intermittent (Yellow) EML light followed by Traction Control and Brake light

Stop using carsoft, have a BMW Indy shop or anyone with the INPA, Autologic, etc. pull the codes. It could be a throttle position sensor.

After further research, it looks like the descriptions for those codes were for a regular e46 (non-M3)

Based on NikolaiD's M3 code list/descriptions, the error codes make a little more sense... including error code #230: Electric throttle: setpoint/actual-value monitoring... which is blank for a regular e46, but looks like a Throttle position sensor (TPS) error code for the M3, like you pointed out illestminimike

http://www.chitownm.com/forums/showthread.php?p=61655

Need more time to research, but that could make complete sense that carsoft read the right codes, but gave them the wrong descriptions

Re: Intermittent (Yellow) EML light followed by Traction Control and Brake light

My issues that I had with those lights ended up being a throttle actuator and a tps

Hi, Since it ended up being a throttle actuator and the tps, may I ask what exactly you did to fix that, was it a diy, and were there new parts involved. Thanks any Info will help..

Dealership fixed it. 1275 for the actuator installed, I got it for 635. Oh, and it was 130 for the tps

Same thing happens to mine every once in a while.. and then I turn the car off/on again.. and she's fine.

As soon as I can find the time I'll pull out my pedal tps and see how the voltages are.. If anyone else has suggestions that worked, let us know!

Re: Intermittent (Yellow) EML light followed by Traction Control and Brake light

Brake light means more than the tps. Could be dsc module. Go by the codes.

Same thing is happening to me but without the engine light. Might be wire to the wheel speed sensor like said before.
