E70 Heated Seats Retrofit

I want to retrofit heated seats into my E70 X5 and I only want a 100% OEM looking solution.

Coming from the e46 / e39 / e9x school of thought I thought this shouldn't be too much trouble but alas there's no heated seat retrofit kit available from BMW for the e70.

However, I'm sure it is possible. In fact I know it is because the nice people in Cartronics.co.uk said they could do it but quoted about £2,500 which is bit steep for toasty buns.

I've done a bit of research so far but have not yet found a how to guide. I've also spent time on bmwfans.info looking at parts diagrams for E70 X5s with factory heated seats and without but there does not seem to be a difference in seat part numbers between them, nor are there clearly identifiable parts for heated seat pads.

I figure there are a number of separate parts to the solution to this problem and it's the heated pads that has me stumped.

1. The buttons - that's solved. I just need to replace the heating controls for a unit with the heated seat buttons like this one
http://i.ebayimg.com/t/BMW-X5-E70-06...Sq5Z~/$_12.JPG

2. Wiring - If the loom required isn't there then it'll be a matter of retrofitting it / running the required wires. This isn't a huge issue.

4. Coding - the heated seat option needs to be added to the build. Again this is not a big issue

5. The heat pads - here's my problem. I don't really want to go buy 2nd heated seats as my seats only have 23k miles on them and replacements seem pretty pricey on ebay. I'm wondering are heated seat pads available for the e70? How are they incorporated into the seats on cars with heated seats from the factory? These must go on the blink from time to time and can't require a new seat to fix every time.
Alternatively, would the retrofit heat pads from an e9x work?

If anyone has any ideas on how I might do this please let me know, there's plenty of smart folks on here so someone must be able to work it out.

Thanks
John

Theres a guy in eastern Europe that sells brand new genuine heated set pads plus looms full kits about 250 from e9x range which are apparently almost universal as a lot of people fit them too the 1 and 5 series il try dig the link tomorrow John


Oh and 2.5k is an absolute joke :dodgy:

Cant find him now , have posted on the uk site I seen it last hopefully one of them has a link

What about the E46 Gar?

Thanks Gar.
I saw that interior too but my carpet is beige rather than black so it'd clash unless I changed that too.

Thanks Gar, I've sent him a message via eBay to see if he has experience of them being fitted to an E70.

Thanks
John

No worries keep us posted with how you get on

He's a sound lad, immediate responses. He says that they can be fitted to an e70 and that the plugs are the same as the e90.

I think I might be buying something tonight.. I'm just waiting on a postage quote.

Here's an update.
I bought the e9x heated seat pads from the lad on eBay in Gar's link above after he confirmed they'd work in an e70.
It turned into a mini group buy as Andy and Conor got in on the act so we got a bit of a deal.

I also found the heated seat button I need, on an e70 these are incorporated into the air com controls so these are on the way now too.

My plan is that when it all arrives I'll get the buttons fitted, get any wiring and coding done and test fit the heat pads but not under the leather. If it all works 100% then I'll get someone to carefully remove the leather, fit the heat pads and replace. Possibly Nolan's but we'll see.

My next move is to call Mick in Germaniks tomorrow morning.

Thanks to Gar for getting the ball rolling on this.

Glad you got sorted john

Now someone go and find me a switch pack with heated seats, harman Kardon, rear blind and ASC button :D

:D

Done that already smart ar$e but none to my spec!

Did you try eBay USA?

Will be a pig to find but one will turn up eventually you might have to settle for one with an extra button or two :)

Just buy some of these and be done with it :D

Be a nice addition alright, good man Gar good digging :cool:

E39 pack fit in the e46 is well I think ?


[hr]
No this is were its at chris :D

There's a good few on eBay USA so just need to wait for the right one. Afaik you can interchange the DSC/ASC switch packs. I think a fella on driver done it before!

@Chris, you know me and my extras :D

Ah even I know it wont fit there :D:D

Those heating pads fit into any BMW if you are willing to cut them a bit. You got these fitted yet? Hog rings suck.

John, there's a place in Crumlin doing these retrofits everyday.
I don't know if they can wire to the OEM buttons or not, but maybe worth a call.

My cousin is getting a sunroof fitted and while I was dropping him there, they had a line of brand new cars all getting one or more of the following retro fitted, sunroof on a brand new A6, heated leather in a new Toyota Rav 4 and sunroof to 3x i40's.

They said they do it all the time. They are well aware of cartronics, and maintain that they used to supply cartronics (Gerry) while they were in operation here.

It's the autoglaze place in the little industrial estate on the left hand side just as you cross over the canal heading out of town into Crumlin.

Thanks Keith, do you have their number by any chance?
In all honesty I thought aftermarket sun roofs disappeared years ago.

It's the wiring that seems to be the tricky part on this but it's definitely worth talking to them.

Thanks

Off topic but I thought retrofitting sunroofs was a huge no no , from what iv heard no matter how good the installer its not like factory its never right and will leak at some stage

Thought of you john :)

It might not actually be that bad a wiring job. Depending on whether you have a "high" or "low" system to install it's either a case of:

- 2 wires from the JBE module (junction box electronics)
- 1 wire from the JBE & two to the power module.

connected to the seats.

You then have a module under the seat SMFA & these connections go in to it. Then the heated mats connect in to that SMFA module.

Thanks Mark, that's a great help.

I do have one query, do you know the difference between a "high" and "low" system?

I was planning to fit the e90 seat pads so I wonder would they determine if it is a "high" or "low" system or is it something else?

Thanks
John

This article describes two types of e70 heated seat options. http://www.bmwmotorsports.org/pdf/e70/05a7_E70%20Seats.pdf

The basic one (as fitted to sport seats) has 2 circuits and the more complex one (as fitted to the multifunction seats ) has 4 circuits. I presume this is the difference between the "high" and "low" systems.
