500E Help with replacing my seats. (bonus interior question inside!)

Hi 500E family.

I'll spare everyone with a long sad story, and provide the CliffsNotes for context, as I probably have an unusual or unfavorable desire here...

Back in late 2018, my 500E sat inoperable for a few days while I tried to replace a stuck ignition switch. While the car was inoperable, my area suffered a flash flood, and the car was partially submerged in floodwaters. While the car suffered no engine / mechanical damage (still runs as great as she did before the flood!), as I was in the middle of replacing the ignition switch, my driver seat was in the most rearward position, with my steering column in the most extended position. Needless to say, they're stuck there.

Given the circumstances, I decided to replace everything from the dashboard down, including the seats. Removing the stuck passenger seat wasn't too difficult, as thankfully it was in a position where the bolts were accessible. Unfortunately however, removing the driver's seat was excruciating, as the rear bolts were completely inaccessible. To make an even longer story short, I ended up shattering the seat base in order to remove the seat.

I know the V8 cars have different seat bases than I6 cars. Since I destroyed the seat base for the drivers side, swapping bases isn't an option for me.

As a temporary solution to make the car [practically] drivable again, I'd like to install some aftermarket seats. I was eyeing this set from corbeau.


Does anyone have any guidance on installing aftermarket seats in our cars? Not so surprisingly, I can't find anyone who actively offers a pre-fabricated seat mounting brackets. Am I going to have to find someone capable of fabricating custom seat brackets? Any one here ever do that and provide some feedback?

Bonus Question: How can I begin troubleshooting the telescopic column?

Thanks everyone.
 
Electrical is not one of my skills however you might start by replacing the convienience module which is located under the drivers side back seat cushion. It and the fuel pump relay are low in the car and may have been compromised.

I've not read or heard of anyone retrofitting aftermarket seats into any W124. If you need to replace the seat bases with the motors and modules, I have two. If you need any measurements, I could also supply them.

Sourcing a V8 seat base should be possible. I believe I just saw one on Ebay yesterday. It was offered by a member of this forum.

Thanks for the reply, sheward!

I've begun sourcing replacement components that were in the floodpath, a new convenience module, headrest actuator, FP relay, central locking pump, etc.

I saw the driver's seat base on ebay- and will consider this as an option.

Side note- I do have a complete sportline set (in ROUGH condition) from a 300E. I imagine the motors and modules are the same, it's just the mounting brackets that are different?

Thanks!

I would think so, but I am not certain. I'm sure someone else here can verify.

Upon further reflection, quite a few have installed Recaro Classics. Maybe someone will answer your question about mounting brackets.

I have recently taken apart a 400 and 500 seat rails. Still have a spare set of rails and bases. There were slight differences in how seat bottom is attached to the rails (500 had wider bolt pattern) otherwise everything matched between them. Can take some pictures later today
 
I'm sorry to hear about the flood issue, but afterall it didn't get a full dip.
As for the telescopic steering column; as you know it is two applications with or without memory, but the el.motor and the entire st.column is the same for both applications. Which should simplify your parts search. :)

I have collected all parts for a dual memory seat conversion and the only difference when it comes to the steering column was just another switch sitting in the steering column cover, having two vs. three wires hooked up to the el.motor IIRC.

I have the front seats for sale and also have V8 seat bases available. All are listed on ebay as mentioned. I need to put up a f/s thread on here for the seats.
