What is this plug from?
Tonight I took off the lower aluminum reinforcement plate under the front subframe for the first time and found this plug sitting on it. Anyone know where it goes? Looks like a plug for a drain hole or something. Also found a clip for the air filter box but that one was easy to take care of. 2009 535xi 6mt wagon. https://cimg8.ibsrv.net/gimg/5series...e22cf81f8.jpeg https://cimg0.ibsrv.net/gimg/5series...50c2a8f78.jpeg |
Which aluminum plate? The stiffener plate under the subframe? |
Yes. A previous owner would have dropped it and it fell on the aluminum plate under the engine. Took it off to change front differential fluid. |
Bump. I guess no one has seen one of these before? I’ll try on an E90 forum in case it’s a part that’s N54 specific.
|
It is on my automatic tranny by the flywheel. It allows access to the bolts that hold the torque converter to the flywheel. On a MT car I haven't seen this cover before, but it may be for the N54's MT.
|
Oh right, most cars have a plug on top of the flywheel to check if it is at TDC. I’ll look to see if that’s the case. |
No, not on top. Next to the oil pan, I think on the passenger side.
|
Oh, okay. I noticed an opening at the bottom of the bell housing where I could see the flywheel so that must be for TDC monitoring, but it was a square hole. I didn't look on the sides but next time it's up on ramps I'll check. Thank you.

The c shaped deflector on the plug is oriented towards the ground when you reinstall. |
