EML Light

[///m325i]

So here's my dilemma. I've been fighting an Eml light on my car for the past month. I replaced the front Tps sensor (one by the oil filter housing) and I installed a new throttle actuator (comes with new tps sensor on it). The only last tps sensor is my pedal but I don't want to just keep buying parts not knowing if that will fix it. I ran the codes and it comes back with "E6 DME: Electric throttle: setpoint/actual value deviation" which I've also seen it under "drive by wire, throttle position failure". I did a "throttle adaptation" with my scan tool and it said it was okay. What happens is when I go full throttle at higher rpm the eml light kicks on and the car goes into limp mode. I noticed when I have the key in the ignition set to number 2 (car not running) and I press the gas pedal that my throttle bodies open all the way at about 75% throttle on the pedal. That seems weird to me. If I keep it full throttle the actuator just closes the throttle bodies and won't work until I turn the ignition off and on again. Same with my Eml light. It will turn off once I turn the car off and on again. Any input would be appreciated.

It’s probably not your pedal.

How is your airbox attached to the car? Using the oe hose clamps or worm clamps? If the latter, could they be interfering with the throttle linkage?

Are you able to move the throttle linkage freely by hand?

This happened to me around 7 months ago. I had it towed to the shop and the shop took apart all the throttle body assembly and gave it a good clean. Adaptations were all reset
and was working normal.

If you are not using OE clamps on the boots, that really could be your issue. I have seen it over and over and over.... you have to be really careful with the linkage.

These were the results of my adaptation. My buddy said there might be something wrong because it shouldn't be "0.00". Can anyone confirm?

Where can you find this adaptation in the Schwaben tool? I've never seen anything like that, would be great to try it.

If you had something interfering with the throttle linkage shaft that runs from the actuator and you fix what was interfering, does the actuator need to be recalibrated with a GT1 still? (with 2 new tps's installed)

[///m325i]

I only calibrated mine when I did the actuator just to be safe. On my last m3 I didn't calibrate it and it was fine. I would try to run it as is and see how it is. I'm sure it would be okay.

The pedal/sensor goes bad more often than people think. I've replaced mine twice over 7 years...same issues and EML you are describing here.

I press the gas pedal that my throttle bodies open all the way at about 75% throttle on the pedal. [/QUOTE]

This sounds more like the throttle body motor position encoder is bad -- not giving the proper feedback position data to the motor controller. If the intake hose clamps were too tight or bad then the throttle bodies should not able to open 100% as reported.

It was interference with one of the hose clamps. Once I rotated that clamp everything ran perfectly fine.

If it was an interference with the hose clamp, then how did the throttle bodies open all the way with 75% pedal down?

[///m325i]

When I did that test it appeared they were open fully at 75% throttle but it was actually hitting one of the hose clamps. I had a friend press the pedal as I looked in the engine bay compared to me hitting the gas pedal by myself and peaking through my windshield. So that's how I figured it out. Once I rotated the one clamp the car ran perfectly fine.
