yesterday i started my car and it sounded like a vacuum cleaner, I opened they hood and this thing was making that noise. It never did before. What is this and why is it doing this now.
It is only spinning when my engine is hot, after 1min it stops.

Secondary air pump installed on 97+ BMWs.

It's an emission control device, helps with the emissions when the car is cold by adding air to the exaust. Usually works when your car is cold for a minute or two. If it didn't work before then there was something wrong with it. :)

It's supposed to make a sucking noise when you start the car(if the car is cold).

If its bad it'll give you a check engine light. Well it did for a buddy of mine and it cost a fortune to replace.

sickfinga,

KASIR, is right that is the secondary air pump and pulls air in to the exhaust. the part costs around 3 bills from the dealer. I had mine replaced at chucks for a bill 50 + labourYou should notice that you get a rough idle

hope that helps

It is suppose to make that sucking noise for about a min or so..
so it is normal.
