Funny timing - exactly same thing that happened to me a few weeks ago. I have a GPS on the way from bmwfnatic.

Glad to know we’re experiencing the same things. I ended up buying a GPS and new detent springs / sleeves / etc. since I’ll be down there. I should probably also change out the CSB, guibo, tranny mounts…

0-60motorsports calling you in here

So I wrote last week that I went for a spirited drive on a relatively hot day with no crank fan... SMG COG light came on, car revved in 3rd gear but I had to limp off the freeway. Turned the car off, waited a few minutes, turned it back on and managed to get to my first destination. I returned home, SMG COG light came on, I pulled off the freeway and waited an hour for the car to cool down. Drove home without issue.

Pulled codes and came up with these:


36 (0x24) Auswertung Positionsgeber Waehlwinkel
37 (0x25) Auswertung Positionsgeber Schaltweg

Quick Google searching has led me to the conclusion that the GPS (gear position sensor) needs to be replaced, but just wanted to know if anyone else has experienced these symptoms. I can hear the accumulator prime properly when I open the driver's door (about 8-10 seconds) and the gears seem to shift fine when the car does indeed shift and not die.

Today was interesting in that the car died shortly after starting and testing the shifts... car was on for about one minute when everything died, battery light was red, oil light was red, etc.

Thanks in advance!

Anybody can help me find that PN for this module ? without heated seats and HK button. thanks in advance !!

I don't know this for a fact, but it may point you in the right direction. I believe that these are made to be fairly modular. The base of it seems to act like a modular cage so you can add and remove switches/buttons. The face plate comes off the front which allows access to the switches.

My gut feeling is that you can do this:
buy a switch panel that has 3 buttons on it. LINK
remove/steal the face plate from that one
remove the face plate from your factory one. remove the switches you don't want (LINK showing the guts)
re-arrange buttons to your liking
install face plate from the second switch panel you purchased LINK
code??

Maybe someone else can chime in on this.

Bumper mounting drama.

2004 M3. Front bumper was a little misaligned so I took it off to re-fit. Discovered the four mounting studs (part #17) that screw into the carbon crash bar were missing. Odd?
Ordered those. Installed them with the spacers on the middle two, no spacers on the outer two.
Bumper goes on, fits well, but will not click into any of the four studs with any reasonable amount of force. I feel like I'm going to start doing damage if I press harder.
I lightly sanded them to take off the very slight edges from production, gave them some light grease. Still no go.
Grease marks on the bumper sockets line up enough that some of them should go, but no.
Tried to press the stud into the bumper socket on it's own and it won't go.

Anyone else experience this? Is the culprit just the 20yo rubber not flexing at all?
Thinking about taking ~1mm off the studs so they slip in easier. As is, they are 15mm OD on the studs and 12.5mm id for the receiving socket.
