location of the boost Pressure Sending Unit
 

Hi where is the location of the Pressure Sending Unit for Turbo Boost in 1986 930?
the boost gage is stock in 1 bar and it was working fin few weeks ago not is stock there

some help please

It's that red item under your stock BOV manifold that looks like it's from a Frankenstien movie. Or if you have a long neck charge air cooler it will be located underneath that.

thanks for the picture, Im new with this do you have a picture with this part on the engine? so I can verify the location.

In addition the problem with the boost gauge on my car is that when I put the key in on the gauge goes to 1bar with out start the car. if I put the key on acc its stay down

Any Idea of the problem

If someone replaced that sending unit in the past the replacement ones I've seen don't come with the odd looking red silicone cover on it.
After market long neck or full bay intercoolers usually have threads for mounting it on the bottom or back of the rear end tank.

still looking where is it I find it ..jeje and how can I test that? and the boost relay???

Here's another picture not my engine. If you remove charge air cooler you will see it.
