clicking noise from dashboard

Postby 5151 mm » Wed Jul 26, 2017 7:25 pm

I have a random but steady clicking noise, that appears to be coming from far inside the center of the dashboard, behind the radio and tripminder. To me it sounds like a switch or relay being operated.
It only occurs with engine running.
There is nothing else noticeably happening.
Different climate control settings have no influence on it.
No warning lights are on.
The auto dimming high beams doesn't work right now, if that matters :)

Since this noise is actually really hard to locate, I'm going to pull some fuses to find out which circuit feeds it, provided it is driven electrically.
However, maybe you have experienced this before or other ideas of what might driving me crazy here.

I recorded the noise from the driver's seat, while idling.

Good audio!

Turn your AUTO DIM switch down until it clicks into position.

That should do it until you can correct the AUTO DIM sensor behind your mirror.

I pulled all fuses, except fuse #1 which is among other things for the Electronic Engine Control (EEC) module, and the noise remains!
I'm afraid to pull the fuse for the Electronic Engine Control (EEC) module and run the engine then to test this one, too. Is it safe to do so? Will the engine even start without this fuse?
By the way, the clicking noise appears very randomly and sometimes comes on very late while idling. But it seems like it can be triggered by accelerating a bit.


Yeah, my AUTO DIM switch is already all the way down, thanks. ;) Another sensor has also been tested, with no effect so far. Different story... :)

The factory Theft Deterrent System, when activated, will flash our hazards THROUGH the flasher relay (the large round one).
Did you remove that also?
