Wobbly driver seat on my C4

[Rob_E]

When driving my C4 (2005 VTR+) on Saturday evening it suddenly felt like the drivers seat was no longer properly attached. So on Sunday when there was some daylight to have a proper look I inspected it more closely, it seems like the bolt or pin at top of the lever/fixing that holds the front right of the seat to the lower part of the frame and allows for the movement when the seat height is adjusted has sheared off, so that the seat can now wobble and lift at the front if any pressure is placed against the backrest.

I'm not actually sure what it is, as it doesn't seem to have any visible thread so may not be a bolt, but from under the seat it looks like that pin (circled in blue) at the other end should have been fixed to the base of the seat holding the seat firm and preventing the wobble but pivoting to allow the seat height to be changed with the adjustment lever.

In this picture I have just moved it by hand, circled in red is where I think it should have been joined on, and looks like the sheared end of a bolt or screw.

Has anyone else had this issue? if so how did they fix it? I was hoping I might be able to get some access without removing the whole seat from the car, it looks like I might be able to see the other end of it if I could remove the plastic trim from the side of the seat.

Does anyone know how to get that off? It felt like there might be a screw near the front under the seat which I may be able to reach with the seat in place, but not sure if there other others further back which I wouldn't be able to get to. Also I don't think it will come of with the adjustment knob and levers in place. How do those come off? I couldn't see and circlips or anything in the gap between the plastic trim and the knobs/levers, though it was a bit dusty. Is there a bold or something behind that centre plastic circle? Though the seat back adjustment lever, left most in the picture doesn't have the equivalent. But I suspect with them in place there won't be much movement in the plastic trim.

Thanks for any help,
Rob

This video may help, I haven't watched it myself

Thanks, unfortunately it looks like he only removes the seat in that video didn't carry on with any dismantling of it; I think it must also be a different trim level on the model he does it on too as it didn't have those adjustment knob and levers on the side that I need to know how to remove.

I was hoping if possible to avoid needing to remove the seat and be able to do it in situ, though that may well be overly optimistic that that will be possible. But at least if I could get the plastic trim off the side first then I can see what I'm dealing with and make sure I've got everything I need to fix it before taking the seat out.

I guess I'll have to have another try and prising those centre pieces out of the front two adjusters and see there is a fixing under there. When I tried on Sunday they didn't seem to want to come out easily. I hate working on plastic trim, it always seems to end up with broken clips so you can't put things back properly afterwards.
