E89 Seats- now resolved (base transplant)

That’s a wrap

The passenger seat was working with some recabling but the drivers wasn’t

It was evident that it needed canbus to the seat which wasn’t provided by the cars loom

I used the canbus from the back of the stereo to close the loop and the drivers seat came to life!

The only thing I couldn’t figure was how to power the bolsters- as the loom was different

Thanks to all that helped and contributed. If anyone needs guidance in future please drop me a line

I am delighted with the result. Stuart did a brilliant job. I would also second his thanks to everyone else who has contributed to the outcome.
Where else can you find such good folk plus the necessary skills to complete a job like this? Imagine trying to get it sorted in a garage.
Another bonus of having this job done is that I have met other Forum members. Nigel ( and his good lady) who sold me the seats and Rob who is a seat expert. It was good to see Dave again too. He did a fair bit of work on a previous car I owned.
Really looking forward to the good weather and being able to get out in the Z again. I won’t mind now if Angela wants to drive (occasionally).👍👍👍

I’m just glad Ian had a garage that is well equipped and heated

Poor Ian, just think how much his utility bills will be this month. And he's a poor pensioner! :P :wink:

About bloody time too!
Good job you don't charge by the hour! :poke: :poke: :rofl: :rofl:

I would ask for a refund on that charm course you attended Andy. 😀😀😀
I would hope Stuart knows I'm joking. :thumbsup:

I’m sure he does Andy. There is no harm in a bit of banter. He would be more worried if you were polite and charming😉😉😊😊😊
 
Bolster Loom:

Start with the old passenger seat. You should be able to cut the loom free from the old seat wire harness. All the wires are taped together but once untangled they are separately wrapped.

It'll look something like this:

Bottom left corner you'll find this plug:

20240226_215809.jpg

It has 4 wires. Red/black, brown, green/grey, blue/black.

At the main yellow seat connector (x275) you will have a Red/black wire and a brown wire. These are the positive and ground wires.

Top right corner you will have the switch for the bolster:

There are 3 wires. Colours are: Red/black, blue/black and green/grey

Detach this loom, now with the passenger loom out that should help you work out how to free and cut out the drivers seat loom.

My electric drivers seat is in my car but from memory the bolster loom is not integrated in the main electrical box:

You should be able cut free the drivers similarly to the passenger side.

If that fails I have already unwrapped the passenger loom and have a drawing of the loom and pictures so you can make one up.
 
Just looked at this Rob. You don’t let the grass grow under your feet. In truth, it doesn’t mean a lot to me but I’m sure it will to Stuart. Thank you for moving so quickly. :thumbsup:

Well done Stewart, good to read that the headache is now over lol.

I think the next thing Ian may be wanting is a heated steering wheel…

But thank you!
Thinking about the heated wheel. I wouldn’t say no to one but since our cars are garaged I don’t miss not having one. It’s different if you’re getting into a freezing cold car that has spent the night outside. Then I can appreciate why you would want one.🤔

I keep telling everyone I am as you described me, “a poor pensioner “. But it doesn’t seem to make any difference I can’t get any price reductions. 🤦‍♂️🤦‍♂️🤦‍♂️ that’s why I am poor.🤗🤗🤗

Well! This evening Stuart completed the final stage of modifying my manual heated seats. They are now fully electric with memory and inflatable bolsters. It has proved far more complicated than we originally thought. But with help and advice from other Forum members Anubis Z and Uncel. The work has now been completed. Many many thanks to Stuart and everyone else who offered advice. I am over the moon. So I can now say with confidence that the car is even better than when Pondrew (against his wife’s wishes) sold it to me. :thumbsup: :thumbsup:
 
I'm glad you have finally got the seats all working now! A real team effort :D

Seems like it's easier to fit E89 seats in an E85 than an E89 :rofl:

You are probably right. But many thanks to you guys for all your help. Shows the value and the strength of the Forum.
I am absolutely delighted with the seats. It is so much easier to make minor adjustments on the move when they are electric and then store any changes in the memory. 👍👍👍

Yours or the cars Ian? :rofl:

Glad it's all working now, love my memory seats, as does Angie :thumbsup:

For reference, the memory seats on the G29 are for both seats and not just the drivers as on the E89. The buttons are on the door cards by the door pull, which I think is a good place for them.

Not much stored in my memory these days Dave. When walking from one room to another I forget why.
Do I come here often? 🤔🤔
I do love the seat conversion though. 👍👍👍
Thank you for your help.👏👏👏👏
 
I'm glad you got them fitted and fully operational Ian, and that you are really pleased with them too. :thumbsup:

But I'm sure we'd all love to see a photo or two!

Hello Gents

I have been reading this post with interest. I have just bought a set of ivory white seats for my 2010 E89 Z4 as I absolutely love off-white seats in my car. In the process of restoring them and will post once I have finished restoring them.

From reading this post, I am getting a bit worried as my current seats are manual and the new seats are electric. Can you guys let me know if its a case of wiring and finding power for the seats or is there coding thats required. Do you guys have the connector pin diagram for the driver and passenger seats?

Any guide/help is very very welcome!

P.s. Dave, we have chatted a few times before - you recommended the Mr12Volt module which I have bought and am loving. Needing to remove again as have that HVAC issue I mentioned. Maybe a job for tomorrow!
