Dumb Question Thread - No Flaming Allowed

[Darbshaw]

Just had a check and confirmed:

- zero point adaption happens during the pre-drive check every time you start the car.
- 100% point adaption happens in the followup (period of time after the car is switched off after driving) if one of the following is true (virgin DME, EGAS/EDK adaptions cleared).

So yes - clear the EGAS/EDK adaptions and it should happen next time you turn the car off. (it can also be triggered over DS2, but clearing adaptions seems like an easier solution)


Also fwiw if you have an OBD2 cable you can use MSS54 DS2 Tool to both clear the adaptions and read the live values the DME is receiving from the pedal.

Thanks for this! I'll give it a run and see if this fixes it.

DS2 must be a newer one, I've never heard of it. My E46 M has been relatively trouble free Atleast for smaller issues like this. She's a track only car at this point so it's a pain in the butt to diagnose smaller issues like this.

I do have it registered, just driving a no ac gutted interior car isn't so appealing when I don't have to

Stamp shows 11.00, so November 2000

Under the electrical connector, it should have the week of the year and the year.

Not really in AI's wheelhouse.

Yikes. I had a feeling it was wrong. Thanks

I've been struggling with an Autosolutions SSK installation. Finally got the shift arm carrier inside the transmission ears and it looks to me like it's 99% aligned but the pin won't go in. Any tips to get the last 1% adjustment?

I recently installed an Autosolutions SSK on my E30 and I used a big pair of channel lock pliers to force the pin through. I can't remember if I used the pliers as a lever against the tunnel or I actually squeezed the pin through the last tab with the pliers but they got it done. It was struggle trying to get the pin/clip in by hand.

Can anyone tell what manufacturer date my pump is? Grok thinks it's a 2019 year

I haven't done the adaptation process for the new pedal yet.

Do you know the process for this? Or is it just resetting adaptations? (I'm going to google after posting)

I did test the wiring harness for proper voltage and ground. All the pins did their parts, so I'm ruling out wiring unless you all feel otherwise. I need to get real jumper pins so I can get the multimeter in the back end of the plug before I can test plugged in. I'll see what Amazon has to offer in the meantime

As for the EML itself. The light will be intermittent and then came back on today after a few minutes of idle.

The pedal has two position sensors in it, one that measures a 0-5V range and the other measures a 0-2.5V range. The DME compares the readings from the two to ensure that they both agree on the position of the pedal.

When you swapped the pedal did you do the adaption/learning process? as I think the DME has to learn the ranges the new pedal is reporting.

Second thing would be to look at the actual values the DME is seeing from those two sensors and see whether it's that they're not quite aligning, or no signal at all from one of them (could point to wiring issue), etc.

I'm at the point where I'm thinking about putting in a smaller pin and calling it good 😆

If it makes you feel better, I did struggle with it for quite a long time. I actually forgot, I did give the end of the pin some additional beveling in an effort to get it fully seated. Not sure if that helped, the lightbulb moment for me was that it popped in when I torqued the pin at an angle more than I expected. A little grease always helps too.

I did as well. I believe what got it done was massaging two pry bars. One between the tunnel and the pin to create pressure on the pin. Another wiggling underneath, above, etc to get the end of the pin to line up with the trans. I found that mine needed to be tweaked to set it. Few hundred miles on it now, feels great.

What replacement options do we have for the gas pedal? I'm getting a consistent limp mode on the track car that has me stumped.

YES

Pedal-position sensor, comparison fault

So far I've only replaced the pedal with a 60k mile unit off Ebay but the code persists. Do we need a particular pedal for the M3? The 60k unit was off a random E46 PN: 35406753518. The original pedal on my car was PN 35406762480. Although the PN shown on real OEM is 35426786281.

All of these are different and would make me believe that this pedal should be interchangeable between cars. Even the Bimmerworld listing shows all E46 models as compatible. Would our cars specify this issue being a TPS fault? Or does it just point to pedal sensor regardless?

Any help here is appreciated!

If it is not the pedal, it could be one of the other TPSs. After that, I would check that the throttle actuator plastic rod end joint does not have play or a crack in it.

All E46 pedals are the same (other than autos which have a removable kickdown switch) with certain part numbers being superseded. 518 should work. If there is 30 day returns, you can try another pedal.

Edit: First try what karter16 posted below.

Carly is good but it isnt free, yearly subscription.

Thanks, dude. Much appreciated.
