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.

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!

Thank you, sir! 🤝

Anyone know the PN for this plug that connects to the throttle position sensor above the oil filter housing?

My boot is worn out and I’d like to replace the plug but can’t find the part in RealOEM

Is there a way to do an ABS module bleed without using INPA?

yeah but super ghetto. Drive the car, brake hard and engage ABS, bleed the car. Keep doing it and you'll have flushed it out by some point

Personally, I use the Schwaben tool (foxwell) as it has various operations like this. Pretty cool, just press some buttons, bleed that corner, then move to the next and it will engage abs each time.

Does anyone know where I can find replacement headliner door trims? The current ones on my E46 are spent after the original owner did a slipshod DIY headliner replacement. I got a new headliner installed however the upholstery shop I used couldn’t replace them and just glued the existing ones back on.

Looking at having my axles rebuilt and/or buying a new set.

What is the difference between part numbers 33217839466 and 33207839468?

466 is the newer part. If buying a set, you want 33217839465 & 33217839466. I bought a set from Cotswold a while back. Not sure if their pricing is competitive now or not.

It’s not a typical oring size. I'd get the correct one using the part number unless you can find something close. It’s a pretty fat oring. The fit is very very snug.

Ended up finding some on Amazon

Anyone thats done a ZF swap, can you confirm that a 330i 5spd driveshaft works? I've gotten one with a blown out CV needing replaced. I may be able to test fit this weekend, but ideally I'd like to have a plan set before the trans is back in the car and then waiting on finding a new shaft. Timing is a bit short for me.

Thanks!

Yea I think it has gone out to pasture lol. Luckily it’s not hard to access, gonna put in a generic O ring from Advance and see how we’re doing.

That is a significant leak for sure. I wonder if there even is an oring in there.

Here’s a video, I would blow into the area to clear the smoke and you can see how quickly it accumulates.
