My front drivers electricly adjustable head rest stopped working today and I'm wondering how to get in at the workings of it.

I was returning it to it's rest position when it suddenly stopped adjusting, I can still hear the motor working though.

I notice that there is the large back section of the seat, does this simply come away to reveal the innards? Not wanting to try removing it, just in case.

Anyone else been here, or is it going to be a dealer job, new seat perhaps :3:

I have the same problem with my passenger seat, it also is a common problem - the fix is relatively easy 'the experts say' as long as the fault is
not the motor or an electrical failure, the outer shelf of the cable that moves
the 'head rest' needs to be 'shortened', somewhere on the 'web' there is
a 'how to fix instruction', can anyone help ?? :crying:

If you have an BMW ETK you can see the diagram of the headrest motor and drive. I'm not sure if all the M5's share the same seat but at least on my car it is a simple process of removing the rear panel of the seat back. There are two screws that hold it in place at the bottom right and left sides.

If you don't have the ETK, it is available online here

I got it, well the ETK that is...

So this back panel simply comes away from the seat, it's not stuck down will adhesive or something too is it?

Reason I ask is that I have tried giving it a gentle pull from the top but was afraid of damaging it.



From the above images, is it simply the two bottom screws that come out, does this then allow the back to be removed?

Plisken,

I started worrying that I gave you some bad advice so I went out and took my rear cover off my seat. Procedure is as follows.

1. Remove the two screws.
2. Carefully pull the bottom section directly away from the rear seat, try to position your hands around the anchor point for the clips(see picture) this should undo the two pressure clips. (not sure what they are called)
3. Once bottom clips are free slide the rest of cover upwards to release upper two clips.

This picture shows the top clips(black colored) and bottom clips.

Maybe I might get around to actually fixing my headrest now that I have taken the back off! Thanks Plisken:)

Sounds like a task for this weekend, as long as I can gain access to the two screws, it should be simple enough, hopefully what I find once inside wont be too bad.

will let you know how I get on...

Alright, I did the headrest motor today. Unless you want to spend a great amount of time taking the screws out I strongly suggest you get a racheting combination wrench like the guide in the last post says. A 7 peice set of Stanley Professional grade costs about $60 dollars even in Hawaii. Well worth the investment. After removing the two mounting screws you need to push the motor as far UP as possible. The way it is mounted you cannot pull the motor out as the other guide says because the cushion is in the way(I tried for about 10 minuites and gave up). The rest is as the other guide states. BTW remounting the motor and getting the screw holes to match up was a real PITA for some reason.

Also if you have been told that your motor is dead ($400+ part) because your seat is TWISTING they are most likely WRONG!!!! ONE motor controls BOTH sides of the chair so if one side is moving then that means the motor is working!!! This job is NOT easy- I say you should put asside at least 3 hours to finish this job. I have worked about 3 hours doing this + the headrest and still have not finished. In my great joy at seeing the chair working properly I did a really bone head thing, I placed the torch down and forgot to turn it off thereby making a nice 1 inch oval burn mark on my newly restored door panelouich :sad2: That pretty much ended my work session as I felt like throwing up. So please be carefull and not stupid like me.

As a Jedi Master I also saw in a "vision" that it might be tempting to think that removing the metal brackets that holds the front two motors will make removing/installing them easier. This is probably true except that the metal nut you see from the bottom side of the chair is actually attached to said bracket causing you to bend the bracket instead of removing the nut. Of course I avoided this mistake thanks to my mastery of "The Force":3: .

Have Fun,
Wyl

Hello,:typing:

May help you on that one as it seems an eternal bmw pb then on M cars. I had the same problem last year with my M6 (yep...had one of these as well...joy of car trading maybe !:byee55amg )

So what i've read from you guys seems exactly the same(ish) back seat engineering than a 635 anyway. the cable move or turn...the motor move as well....well it is annoying because when you press your switch the motor works...but the headrest is lazy and do not want to move).
Well the solution cost 30 minutes and it is free (assuming you have a metal coat hanger laying around somewhere)

here is the link for a 635. Looks really the same. I am sure it can be worked out this way.

OK,

I think this has to be worth a shot. I take it this is the standard repair that BMW would do if you took the car to them? Or am i being completely nieve (excuse the spelling).:flag:

Jon,

Ask them to fix the headrest cable, they might. I did not know better and was told by the dealer and a specialist shop that the motor was broken and I would need a new motor (400 USD PLUS Labor). Fortunately I was too cheap to pay them to fix it and eventually found out how to fix my supposedly broken motors.

Thanks for the heads up.

Today is definitely an M5 day. It is 26 degress and blue skies, so I have driven the M5 into work as a special treat to myself. Makes such a difference to my standard commuting vehicle.

Have you ever had to re-gas your AC? If so how much did it cost. Mine has stopped working, knowing that the car only had a new evaporator and compressor 24 months ago i am presuming it only needs re-gassing. Is a BMW dealership the best/only place to go and get this done?

If the temperature gets any hotter than today I am going to need it...!!:cool:

26 degrees!!....are we in the same country? Struggling to make 12 here in Aberdeen....

I guess BMW could do a re-gas but I got mine done by LSUK (the old Lucas Service devision). I think the total was about £90 for a vacuum, pressure test, re-gas and flouricine dye. The basic re-gas isabout £60.
