Air flow security contact 911 110 929 00

[ALBARRAN]

>HI, I have a issue with the air flow security contact or air flow switch 911 110 929 00 in my 911 SC-1982. This contact produce a resistance of 950 or 1050 ohmios, which are not enough to cut the ground contact in the 85 pin of pump release, then the pump stops, even in route, and the engine fall off or can not start .

Sometimes it reaches 1350 ohmios, and then works fine and start

I can not find this part in Pelican or PORSCHE AG directly, someone can help me? When can I to find it? Somer one know the Bosch reference for this part?

I've seen that Porsche has this part out of catalogue, is there substitute or electric diagram modification?

Thanks in advance for your help.
