NEED HELP: Strange Electrical Noise coming from the Dashboard
 

My 930 1987 Turbo having a very Strange Electrical Noise coming from the Dashboard, I'm sure it is not the front Fuel Pump and Not the A/C Blower as they are all brand new parts, the sound is more like Electrical noise it increase and decrease !!! it sound like Zzzzzzzzzzzzz....,,, Sound :confused:

any one have is problem before ?????

Thanks for your feed back

There is a round cabin temperature sensor mounted on face of the dash on the 1987 models (right side of the steering hub) - the sensor has a small electric fan - maybe this is making the noise?

Mine makes a faint noise kinda like a tambourine being shaken while accelerating from a stop sometimes.
A buddies 930 does the same thing. We both have 2 bar VDO/NHS mechanical boost gauges where the clock was and he thinks it's the boost gauge making the noise.

I don't know what it is and just enjoy the mystery.

Could it be the fresh air ventilation fan?

The increase and decrease in the volume, When i step on the gas peddle it increase, now i think the sound is not coming from the dashboard it comes from the top right side of the Gas peddle

I don't know what it is and just enjoy the mystery.
