In Reply to: Here's what that sensor does..... posted by m3niko on October 08, 2000 at 10:42:26:

drive the M3 when the climate is really cold. I live in louisville ky where the winters are mild typically, but the air is still very very cold. I have a camry for those days :) but I'm still curious about my coolant low situation. I know that my installer zip tied my sensor. What other options did he have? Is this going to cause a problem?? I started my m3 yesterday and it was pretty chilly outside, my engine almost died! It hesitated for about 3-4 seconds with a really really low idle, I thought it was going to just die on me, then it came up to the right idle and was ok from then on. I'm wondering if I need to have that sensor reinstalled. Opinions??

That sensor is more like a switch. When the air ingested by the engine is cold, the switch opens and allows coolant to flow through the throttle body. The coolant keeps the throttle body from freezing and getting stuck.

Ideally, you'll want that switch/sensor to sample the air that the engine is getting. That way, it'll work just like it did from the factory. Now, if you live in a climate that never gets freezing temperatures, then you can zip-tie it somewhere in the engine compartment and you'll be good to go.

'95 M3 turbo

I just got my Dinan CAI and I noticed that it does not accomodate the sensor that is pluged into the factory airbox. What do I do about fitting it in? What have you guys done to incorporate it? I'm hesitant to keeping such a beautiful piece of work, the intake that is. I'm very curious. Mine is a 1995 M3, so any of ytou guys with these afermarket intakes, I'd like to here what you did. Thanks.
