Seat Looseness
81 - 100 of 108 Posts
Car was fine when delivered. It was only action that was taken daily by myself and occasionally by wife when she would drive the car. I did it daily for months when it started and it got worse. After frame replaced, no more seat back “slamming” and no more problem...everything else same...Occums razor!

Well with my coupe I very seldom even move the seat back forward to allow passengers in the back seat. I have done that maybe 4 times in the years I have owned the car. So I don***8217;t think that***8217;s the cause of the dreaded seat thump in my case. The car does not see the snow much, but has proven to be very good the few times she***8217;s been out in it.

Can someone mark the area's in the picture uploaded where to apply the grease for the bottom plastic pieces. ?
i'm going to get some Teflon bike chain spray and apply it hopefully it makes a difference.

GREAT NEWS GUYS!!!!!
Unfortunately, after having my entire Seat frame changed at BMW last year under warranty the problem came back. I decided to look into the problem and I could actually see the problem area. Under the center of the seat where the rod is going across the seat and the bushings are on either side of the rod I could see the scratch marks near one of the ridges.
I simply sprayed a liberal amount of PB blaster white lithium grease spray to both the bushings. My seat feels like new again. I figure I'll do this every time i change the oil in the car to keep the problem away for good. Hope this helps someone.

I don't have pictures but it's fairly straight forward. Slide the seat all the way back, then raise the bottom front of the seat to its highest point. At this point you can kneel outside of the car and peek under the front of the seat. There is only one bar that runs across (Left to right) under the seat. On each side you will see a "clamp" with a plastic bushing inside, this is the problem area. Spray both of the "clamps" liberally with the PB Blaster and your problem is solved. Hope this helps.

The reason I***8217;m asking is I did make 1 attempt two months ago , and couldn***8217;t see any lateral bar with bushings I have an F06 2015 GC Maybe my seat doesn***8217;t have that bar ? , so
To understand , you move the seat all the way back then you raise it up all the way and you should be able to see the bar ?

Correct, I have a 2014 F06 GC and I'm sure the seats are the same. You will really need to peek under and almost directly up. If you just look under and towards the rear of the seat you'll miss it as the bar is closer to the front of the seat. The best I can try and describe it is probably just past where the thigh support ends and the center if the seat pan begins. Hope this helps.

You were right i found those stupid bushings, i sprayed it with Teflon based chain spray as someone had recommended will post back with results currently car is in garage having the bushing soaked in grease .... i hope this works at least for a few days otherwise im going to start constructing that damn bracket.

Hi All just wanted to give some feedback ,
So @640jims , mentions the use of Lithium based grease, I do NOT recommend using this type of grease, if you pay close attention the bushing is of s Plastic nature , so lithium contains properties that breakdown plastic over time.
Therefore i went with a Teflon based grease, it performs well in low or high temperatures , is generally used in load bearing situations.
When you look at the bushing under the front seats (This is done by moving the seat to the far back as possible and then raising the seat high to the max) then tilt your head down and look straight up towards the front edge of the seat)
Place a micro-fiber to cover electronics and carpet, then spray liberally "use the straw provided with the canister" make sure you get the inside of the bushing and outside edges.
Let the car sit for a while so the grease really soaks in , then try it out.
Tested my 6 GC 15' right now and no movement no squeaks . I use to get movement by making even the slightest turn , really uncomfortable .
I just wanted to thank everyone on hear for all there help and advise, I might still build the bracket that Allan mentions , its fairly easy to construct.
Feel free to reach out if any of you need some help with this issue.

Wait. What???
You're saying that if a bearing is worn from use or deterioration causing shift in the parts, that teflon grease will fix it? Is this one of those "add water to make the dinosaur grow" parts? :rofl:
Color me skeptical.

The seat is designed to move in he bushings. The problem is that as time goes by the area that the seat is designed to move in gets dry and when it gets to the end of the bushings it "jumps" and that is felt as a shift within the lower part of the seat. the grease allows it to slide without the "jump" so your seat feels new again.
OK gentlemen. Starting to have the same driver seat looseness. It's driving me nuts. Before I pull the seat out and flip it over on my shop bench, the TIS manual says do NOT reuse the Posilok bolts when reinstalling the frame. Does anyone know of a source for these bolts besides walking into the dealership with my pants around my ankles???
