loose black breather pipe ?

AdrianC · Jun 20, 2012

Hi,

When looking under the bonnet today I noticed a small black breather pipe which is not connected one end. I could not see where it went to.

The black pipe is connected to the front underside of the (BMW) air plenium on the left of the engine block, any idears

If it is about 7mm in diameter and connected to the underside of the manifold just above the gearbox/engine oil dip sticks. It goes to the MAP sensor bolted to the left top of the fuel filter. You should have a distinct lack of power with this disconnected.

Hi Wammers,

The black pipe is approx 6mm dia outer, 2mm dia inner hole. its fitted to the underside of the manifold near the front of the engine. approx 450mm long ?

I don’t suppose you have a photo of where it connects to? I could not find the end you refer to.

Thanks

No photo. Small unit with electrical plug on it. Bolted to top L/H side of fuel filter. It's actually a pressure pipe that feeds the MAP sensor. Manifold absolute pressure sensor. To tell the ECM to increase fuel on turbo boost.

Thanks Wammers, found it and yes it did lack power but as I only just brought it I was unsure if a P38 realy was that slow !

All connected now and it drives alot better and I can even overtake .
