Range Rover Adapted X5 Heated Seat Element Repair
What follows is another solution to a problem many of us have been plagued by: Front heated seat bottoms that don't work or partially work...or give you a flaming leg! Before I get started though I would like to thank Turbo_Bimmer for his previous thread (found here: http://www.xoutpost.com/bmw-sav-foru...ement-diy.html) and some of the leg work he put in that allowed me to quickly recognize the necessary wires on the heated seat. Where my solution differs is that I wanted something that would also heat the bolster.....low and behold while cruising the interweb for some Range Rover parts stumbled across an answer. Land Rover offers replacement elements that simply stick onto the foam seat bottom!! What you need: Heated Seat Element: Land Rover Part # HGL000040 (~$70) 3M Spray Adhesive (Super 77) Heat shrink Soldering Iron Scissors Bull rings & pliers (or an upholsterer if you're lazy like me) I'm not going to bother with seat removal/ disassembly as those are already mentioned in previous threads. So this is what you start with: When you overlay it on the seat bottom you get something like this: ...but we need to do some trimming to "fit" it to the X. It helps if you put it against a window/glass table with light under to ensure you don't cut the element. The element is wrapped around in a continuous wire like so (already started trimming at this point): Basically because of the slightly different seat contour you need to cut 6 spots for bull rings on the lateral seams, as well as widen the long cuts between the center & bolsters. You can also either trim off the excess foam from over the bolster or wrap it over the edge. Lastly, remove LR's themal resistor as we want the BMW one sewn into the seat controlling the element. Simply peel it out, and join the two red wires together. You get something like this once the thing is all trimmed up and glued down: As far as wiring goes, simply connect the red wire of the element to the Green/violet wire of the seat while the black of the element gets spliced into the brown. The grey wire going to the leather remains intact as that's the temp control. Boom. Heated seat fixed! -S

Nice find X5SND
Did you measure the resistance of the elements to see if they compare to the X5 one? I suppose they must be close since the RR shares many parts with the X5. |

Very nice. My x has a hot spot on the seat back. Does rover sell the upper part as well?
This would probably work with my e38 as well. Since they share the same wiring setup.

Thanks Guys! I was doing the write-up more-or-less as a play by play as I was installing it yesterday.....but I managed to get the better part of 3 hours seat time in today and can say it does work well!.
That being said I want to address a few items to those that may choose this route. First being that because the element is on the foam and has to penetrate 3 layers of seat material before heating your bottom, it does heat up a bit slower.....but on the flipside also holds it's heat longer if you lower the power level from high to low. Over all though temperature-wise it's incredibly close to the factory heated seat (the back and bottom remain incredibly close once both are "up to operating temp"). Next is a slight wrinkle (or lack there of) with regards to the 6 slots I had to cut for the lateral seams. As the lateral seams on the leather have a rod that "pulls" the seam into the recessed portion of the foam when you attach he bull rings; where I had simply overlayed the element, you may want to dip the element into the cutout so when it comes time to put the seat leather back on....more specifically the bull rings, you wont stretch/break the the element by "pulling it into the seam". Over all though, I have to admit, it's worked out much easier than I originally envisioned! As for longevity however, time will tell. @Turbo_Bimmer - I actually did not measure the resistance...as I just wanted "something that works" for the cold months, as nowadays I only drive the X maybe once every two weeks....I have to admit, although I do miss the driving dynamics of the X, the 510Hp of the Rover is slightly intoxicating! -S

I would assume that the Range Rover pad has the temperature sensor included as part of the pad?
If so, why not just re-use the sensor that comes with the pad? Why try to re-use the original BMW sensor? Or does the RR pad not come with a sensor.... very confusing!
