My 3 series has developed this problem where it likes !!!error: Indecipherable SUB-paragraph formatting!!! when the clutch is depressed and I’m slowing down. I figured I would start looking into this. There are a couple things it could be, it could be the idle control valve, among other things. It could also be a dirty MAF. Since cleaning the MAF is the cheaper option, I’m going to start there.
I went over to my friends house today to feed their cat breakfast; he eats on the table right now as they also have a puppy and it’s the only place he can eat without the puppy trying to eat him. On the way home, I stopped at Advanced Auto Parts and got a can of MAF cleaner; I got a couple of weird looks when I pulled up in the E90 M3, I think it was more looks of bewilderment. I’m at home having a cup of coffee before I go pull apart my intake then clean the MAF off and see if that has any difference.
I guess since I need a new hobby, maintaining two E9Xs on a shoe string budget in an apartment complex parking lot could be one.

Check this out — my Passat V6 writeup (with ECU data logs) from way back in 2010.
Long story short, it works!

Awesome, I’m about to go give it a try then go for a drive.

MAF sensor clean up do marvels.... You should easily notice the difference if you’ve never done it.

On a side note, one way to isolate whether it’s an MAF issue is to just unplug the MAF and go for a drive. The idle should bounce all over the place, but the car won’t die — it should revert to generic air/fuel mapping due to lack of airflow data.
If the car continues to die, though, it’s probably something else. YMMV

My buddy’s 330ci does the same thing and he’s convinced its the idle control valve, but he hasn’t replaced it yet... I’ll pass along the MAF possibility and see what happens. Good luck and keep us posted

I had a similar problem many years ago with my old Mazdaspeed Protege. The car would stall out with the clutch engaged while slowing down. I essentially just had to pop it in neutral, and either heel-toe it or put one foot on the gas pedal and one on the brake.
After trying a bunch of different things, I finally figured out that it was a vacuum leak. The piping at the bypass valve had a crack in it on the bottom, where I couldn’t see it.

After a 15 minute drive it seems to be better.

I assume that asterisk on the 4-10 HP, has to mean your MAF is clogged/shot to the point the car is basically stalling— but still a good easy fix/upgrade on a higher mile car w/ an original sensor.
