A little update.

I took the car to a garage where a friend of my works.. I used a universal obd reader to ceck the codes..

It did'nt bring up any bmw codes, but said something about ixtures on cylinder 1 and 2.. I guess this is the gas/air mix...

I unscrewed the valve, and it looked just about the same as on Charlies pics...

It was broken off in one end, and wedged..

I took out the flap and screwed the valve back on.. Now its running smooth on idle, and the SES light is off.. It also rides as usual..

So, my next question is: what does this valve do..?

Ill order a replacements, and hopefully ill get it next week..

Can i drive without the flap in the meanwhile.?
