I have the seats and in my opinion they are going to add some character to the interior of my C230.
They are also going to provide me an incentive to watch my weight. The previous owner of the seats swapped them for a pair of stock C230 seats. According to the person I bought them from, the previous owner found them uncomfortable. I think that if I put on 15 pounds I might reach the same conclusion. The C63 seats are "aggressively" bolstered.
There are five issues that I need to address before I can be sure of a successful installation. Please feel free to offer suggestions and critiques as I puzzle this out.
1. Physical installation - Since the previous owner swapped a set of C230 seats into his car, I don't think this will be a problem. The seat rails and seat mounting hardware appear identical. I'm going to measure carefully to confirm this before I invest time and money on any of the other areas.
2. Cosmetic repair - There is wear on the driver's seat bolster, and small holes in the driver's headrest and passenger seat back. I'm considering three options for repairing these flaws: (a) Home repair kit; (b) A mobile service such as Fiber Renew; or (c) Taking the seats to an upholstery shop for professional repair. Option c will obviously be the most expensive, and option a will be the least expensive. I've attached pictures of the damaged areas in the event that anyone can share experience using home repair on this type of damage.
3. Air Bag System - According to this article: https://mbworld.org/forums/c-class-w...-any-w204.html
the passenger seat air bag detection system in the C63 seats works differently from a stock W204 seat. I believe the W203 seats are similar to the the stock W204 seats. There are a few options for addressing this article provides some guidance on solutions: You are being redirected...
The best option appears to be installing a seat mat with occupancy sensor from a W203 so that the air bag system will operate exactly as designed. I will also need to deactivate the side impact air bags in the C63 seats.
4. Wiring the power seat mechanism - I have the two-way power seats in my car. The power operates only the back-rest tilt and seat height. The C63 seats are full power with memory. It appears that I have two options. (a) Basic operation - This would by-pass the memory function and use stock W204 switches and connectors to operate the seat motors. I found this video on YouTube that provides some insight:
I posted on the W204 forum and asked if anyone was parting out a W204 and willing to part with the seat wiring and switches. (b) Full memory operation - This would enable 100% operation of the seats including the memory function. I was able to do this on my Porsche Boxster, but it was fairly complicated. I think I will need the door panels from a W203 with memory seats and the switches, wiring and connectors to make this work. That will add significantly to the expense, uncertainty and complexity of the project especially if the system works on the CANBUS. So, unless someone has done this before and can provide step-by-step instructions, I don't think I will spend much time on this option.
5. Seat heaters - Both my current seats and the C63 seats are heated. This looks like it will be "plug and play." I'll need to confirm that when I am measuring the seat rails.
