DRIVERS SEAT AUTO ADJUSTMENT PROBLEM - 63 507 COUPE
Hi all!
Got in the back of my car yesterday searching for a rattle id heard whilst driving and noticed my drivers side seat auto seat forward/back had stopped working! Other than that the seat is fully functional! Forward, back, up/down and headrest all work fine - it just doesn't auto go forward when pulling the seat forward. Anyone else had a similar problem and any tips? My car is a 2013 C63 507 coupe
I have tried unplugging and re plugging all the plugs underneath, which didn't work. I have also disconnected the battery and left it for half hour which also did nothing.
I have left the car on trickle charge all day today to see if it could perhaps be a battery related issue (i doubt this though because the passenger seat still works perfectly fine)
Is there a seperate fuse for this function that perhaps couldve gone? What fuses should i check?
Any tips or things to try are appreciated! Thanks.

If the seat itself moves forward and back when commanded by the door switch, the two most likely components that could be malfunctioning are the seat control module or the microswitch in the seat that detects when you unlatch the seat back and lean it forward. On the coupe unlatching the seat back and leaning it forward also lowers the headrest as the seat moves forward so it doesn't hit the top of the windshield... do you see the headrest automatically go up and down as you hold the seat back forward?
Trickle charging the battery is about as useful in this particular case as letting some air out of your tires... not going to help in any way. If disconnecting and reconnecting the seat control module (or the battery which essentially also resets it) didn't help, chances are either it or the microswitch need to be replaced.

Thankyou for your response!
The headrest does not go up down automatically at current no, but on the door switch is does adjust manually.
I had it plugged in on a fault code reader yesterday evening which said
"THE POSITION SENSOR OF THE ACTUATOR MOTOR FOR HEAD RESTRAINT ADJUSTMENT IS FAULTY. THE SIGNAL DOES NOT EXIST" STORED - 9DBD31"
AND
"NORMALIZATION OF THE HEAD RESTRAINT ADJUSTMENT HAS NOT YET BEEN CARRIED OUT. CALIBRATION IS ABSENT. CURRENT AND STORED - 9DAB54"
So most likely this is what is causing the issue - In to the main dealer it will have to go i think

There you go. The first code indicates it's the microswitch in the seat itself (in this case for the headrest). The second is normal after you remove the battery or the power to the seat control module long enough for it to reset itself as it then needs to be recalibrated with the travel endpoints so it knows how far to move the seat and headrest relative to the position it is in at any time.
If the replacement of that sensor requires that they remove the leather seat back cover, you probably wouldn't want to tackle it yourself unless you're good at repairing shoes or leather furniture. I'm hoping they can get to it by removing just the plastic back, hopefully with the seat still in place.
