I want to add heated seats to my car... '02 C240 Sedan
They are dragging their feet and are acting like they are not going to be able to order my existing seats with heat option because they can’t figure out which ones to get. I am going to go by there tomorrow and see if I can’t help them along. Very aggravating but I am more determined than ever to get this modification done.

There is no variation in replacement parts for this car. ALL REPLACEMENT seat covers come with heating. This is to reduce the number of parts needed to be stored and carried, it is unlike building cars on a production line where the parts can be interchanged with better specifications depending on supply items.


heat cable 203-540-30-05 $53.40 USD List
heat element 163-820-03-98 $118.80 USD List
heat element 163-820-04-98 $297.60 USD List
the heat element numbers used were a 163- because the 168- did not show up in the computer for the elements.
That makes the total a little over $1000. That's not even including the switch banks.
In any event, we would still need to determine if our cars are the lucky ones that have the heat elements already.
Digging around under my seat (which isn't too easy
), I found a connector block labeled as follows:1. CAN (nur F) LS
2. VERS.
3. HH
4. LV
5. HV
6. L/K
7. LE (plus a switch symbol)
8. HE (plus a switch symbol)
9. NB (no pins and no connector)
10. NB (no pins and no connector)
11. FDS (pins but no connector)
Do any of these look like the heating elements?

Adding heated elements underneath the foam sewn to the leather will not give you full benefit of the heated elements...that will be a waste of money and time.
greetingz,
Thank you for the clarification. I guess what appears to be a heating element in the picture is the occupancy/weight detector for the SRS.
If you could point me in the right direction in determining if the seats in my 03-W209 already have the elements. If I'm one of the lucky ones, you've got an order for the balance of the required materials.

Thank you for the tips. Hopfully I can return the favour one day.
Since I'll have to pull the seats, this prject will have to wait for the nice weather to return (when the heated seats won't be needed ofcourse).
Does anyone have the WIS for W203/W209 seat removal handy?

To remove the upright section you need to start from behind the seat with the backing plate.
The US spec W208s were all prewired for heated seats...but didn't have the heated elements in the seats...he US spec W209 might be prewired as well...who knows...

greetingz,
If it costs near to $260 USD for the heated fabric covers for one front seat - would people consider that affordable ? Apart from renewing the trim, it comes with heating also (about 50% of the overall value).
After looking at the prices I think that replacement fabric and twin (man made) leather are not out of reach for most people. Full leather is the one that makes people faint.

On the next nice day I'll take a look and hopefully I can give you an order for the balance of the parts.
To my delight, I found myself original MB 2nd row, rear heated seat covers. The ones that came on the vehicle were non heated covers.
The car came with heated front seats and that's been great for us but not for the rear passengers. I figured it could be a straight forward thing, add the cables from the seats to the rear control unit located under the seat and from there to the switch cluster and voila. Not so.
What I cannot find are the part nos for the cables from the heated seats to the control unit which is under the seat and from there to the switch cluster.
I bought a switch cluster from ebay that has seat heater switches together with the air-condition and temp etc. What I am missing is the cables.
I use the german parts search diagrams online manual 'MB TEILE' and cables are shown as lines on the diagram, it is difficult to read or I don't know how to read it.
Does anyone know where could I see these cables on a proper diagram or does anyone have the part nos of the cables I would need to order.
I can you guys have been down that road and would really appreciate your insight of how to go about this final stage. The new seat covers are already on the vehicle.
Also, would I have to get a new control unit, I am going blind here as I can see a few opening for cables on the control unit under the seat and I figure they are for the heater cables.
Could someone please guide me on this.
MB teile online parts search many times does not show details parts that MB dealers would on their website, would you know of another where I can get more details. What do the gurus use. Thank you in advance
