The ticking sound has gotten worse in the last few months so I need to address it soon. I assume I just got a bad bearing, or Valeo’s QC isn’t great for that part, because Vas described a similar sound.

I would think so, yes...

Just finished my first autocross that had several long sweeping turns and was getting an awful knock after runs. I let it sit for 20 mins and added half a quart of oil and it settled out, but would come back after every run. I assume it was an issue of oil starvation since it went away after some time, so

1. Does that sound like oil starvation to you kids and

2. Am I gonna have to baffle this bitch up?

Edit: nvm it's normal even with the extra half quart

The throwout bearing only spins when the clutch is engaged

Knocking is not normal, but loud ticking is. Yes, it is indeed oil starvation, and happens to a variety of BMW models. Some people say the trick is to pour an extra half to one whole quart in over full to mitigate it, but makes some people uncomfortable doing so.

That is one of the reasons I don't auto-x anymore.

Yep, I'll be around.

Taking my car into the local dealer to have oil done this Thursday, but figured I'd ask here before I brought it in.
I just noticed late last week that my passenger side floor mat and carpet were soaked, causing a pretty nauseating smell in the cab, and I can't figure out for the life of me where the water is coming from. At first I thought an AC vent was dripping but couldn't find any wet sources in the footwell. Figured it may be a seal but all around the door and in the door jam the weather seals are plush. My sunroof has been broken for over a year and I couldn't imagine how water would reach the footwell from roof, let alone now after it has never happened before.
My brother suggested it might be a clogged sunroof drain(?) but I'm not sure where that would be to even inspect, plus I can't even open my sunroof right now.
Any ideas?

No idea. Dealer oil changes are expensive, do you have a local indy who can do it?

Possibly vapor barrier. When that happened to my X3 I left a boxfan in the floorboard overnight and it was totally dry by morning with no smell.
