Cold Start

[fredkhaz]

my 2000 996 with 157000 miles on it, sounds like a jet engine at cold start. and the sound goes away with in 30 sec or so.

no light on in the dash, and it runs great.

any idea ?

That is your air pump for emissions -- normal.

I would compare it to other Boxsters - perhaps you just notice it more - or perhaps it has a bearing going.

Removing secondary air pump (USA vehicles only)

Undo the starter ground cable on the body. Open the spring band clamp using commercially available spring-band clamp pliers and push to the rear. Undo the three fastening screws on the secondary air pump. Disconnect electrical connection and remove pump from vehicle.
