MY 06, Power seat driver side, both side mirrors not workin
Lately, when starting the car, ive noticed som relay clicking rapidly from , probably under
dashboard, or maybe the seat, not sure it its any relays there .
But both side mirrors cant be adjusted anymore.
Same with driver seat. totally dead.
Have measured +12V and ignition on signal are present under the seat.
Pass seat working, sunroof working.
Have tried looked through the el drawings. but havent found any comon wires, relays for seat and mirrors yet.....
And DVD navi player, not responding, but thats been out for a few years....D3, MY06

Hello
I’ve got exactly the same fault.
I did change the ECU under the driver seat (LHD) but with no improvment.
I did a fault code reading in the beginning and notice a error code about a switch but didn’t write it down. My bad, unfortunally.
Do you have the electrical adjusted steering rack?
Next thing I will check is the connectors on the left side on the drivers side, ie left of the left leg to see if there is any corrosion in the connectors. This to ensure there is corrosion due to water dripping from the dreaded sun roof drain tube.
I do have water in the foot well…

I would measure the two 12 volt
Signals on the gray plug under the seat.
I found that the white /red was missing 12 volt.
Only measured 7-8 volt.
F18 give supply to F46 and F54.
White /red wire is from F54 and called batt electronic in the drawing.
I did a quick fix, and linked over brown /green(check if I'm correct) to white /red.
Seat and mirrors working.
Will investigate later where the bad connection are on the white /red. Assume it's in the CJB connector.D3, MY06

Interesting. I actually disconnected the grey plug and it all went quiet from the relay clicking.
Also, to be noted, I did splice in the connectors and wires for the electrical adjusted steering column and the splices are in under the plastic cover on the left side. Where the water collects…
However, if you don’t have the electrical adjusted column and still have the same problem, how does the cables/connectors look on the left side on the A-pillar?
The connectors under the seat are all ok.RRS MY06 4.4 V8

Finally got the time to look at this issue again and solved it.
Since I had the infamous water leak from the sunroof and water in footwell I decided to replace the hose from the sunroof. When looking under the door foot trim there was a red power wire loose right next to a bad blue cable joint. It was also covered in a nice blueish green color…
The cable and joint must have been causing a backlash contact causing the computers to never sleep hence the battery drain and a relay ticking getting worse and worse until the joint was completly seperated.
So after making a new joint, soldered and watertight, the movement of the drivers seat and mirrors are fully working again without battery drain.RRS MY06 4.4 V8
