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.

I've done something to my passenger side parking brake and I can't figure what is causing the drag/lockup, so I'm obviously adjusting it incorrectly.... Anyone want to shed light on how to do it properly, I'm tired of screwing with it and feeling like an idiot. k thx

[Nate047]

If it’s a large enough leak yes it can cause drivability issues.

Been trying to un-fuck my other car little by little, I’m working on a series of vacuum leaks. I have a big leak at the base of the oil dipstick guide tube, probably that little O-ring. Do you guys believe a vacuum leak there could cause serious AFR deviations and drivability issues? Or am I likely going to continue to find more leaks downstream after I rectify this one?

I recently picked up a 2002 e46 with 98,300 miles that seemed to be well sorted with service records for rod bearings, VANOS, and basic regular maintenance (oil changes, brakes, etc). I took it to a reputable BMW shop here in LA who found the following faults/made the following recommendations:

- Leaking oil pan and constant pressure valve
- Brake and differential fluid flush
- Worn out engine mounts
- Valve adjustment
- Spark plug replacement

I didn't find service records for these and I wasn't expecting issues to pop up, so my question is whether these are known issues for a 98K vehicle and if there's a chance I'm getting taken for a ride by the shop.

How long ago was the VANOS rebuilt? typically a vanos rebuild should include valve adjustments, valve cover gasket, and possibly spark plugs.
