Hi

I saw that the connector to the bosch box not was mounted? What does it?? it does not matter whether it is mounted or not?

I presume you're referring to the little black box beside the air filter? Does it have a part number?

[Brinkland]

Yes, partnumber: bosch 280 101 001

It's an air pressure/altitude sensor:

I would imagine it's fairly important to have it connected. If you're worried about the wire being loose, use a tie-wrap or similar to secure it.

Thanks, now I can find it at bmwfans.info

it's supplied with a catalytic from the factory, but I can see there is mounted an ac schntzher manifold, and 323i exhaust system (without catalyst), therefore it is disconnected?

Perhaps it caused fuelling problems, so a previous owner disconnected it. You could always reconnect it, and see what difference it makes...
