Seat Control Module reprogramming required?
My seat would only go half way forward so I got another from eBay but nothing works when I plug it in. Do these need to be reprogrammed or reset before they work? I plugged the old module back in and it works, except the half way forward issue.

I also have this issue.
My passenger seat is too reclined even at its most upright position using the button. I read some where that there is a seat reset sequence. All the way back on the rails and hold for 5 seconds then the same forward. Going to try tomorrow.

Back to the modules, I still have two bricks that don't work because they probably need some programming done to them.

Thanks for replying!
I tried that but it didn't work. The halfway forward issue ended up being a bad solder joint on the headrest motor hall effect sensor that prevented me from going all the way forward (code reader didn't lie). Apparently the computer didn't want the headrest to rip up the headliner if the seat and headrest heights were all the way up and then you tried to move the seat forward. It WILL hit the headliner if you do that. The computer starts to lower the headrest as you move forward, assuming it actually is working.
Back to the modules, I still have two bricks that don't work because they probably need some programming done to them.

I have a service booked for tomorrow at a Mercedes service centre and will provide them your learnings.
Hopefully it is not an expensive fix!

Do the new and old seat module part numbers match exactly? Seat modules are interchangable without any coding. Your ebay seller might have sold you a bad one.

When I explained it, they sounded confident that it just needed reprogramming, even though I printed out your comments and gave it them. I picked it up and they told me it was all sorted (no charge!). In fact it was exactly the same as it was. They reprogrammed it again, still the same as before. A bit annoying. I think maybe an auto electicion to look at the solder that you mentioned. What do you think?
