Roof Lining sagging

So just a small " How to" on a problem I noticed with my Z's head lining

I notice the head lining wasn't complete uniformly taught across the inside of the roof when the roof was up and viewed from sitting inside the car, there appeared to be a small section that was lower than the rest. For me this was just above the drives seat, but apparently it can happen anywhere across the head lining.

Ok so I decided to take a look and see what was what. I managaed to get my local stealer to send me via email a parts diagram of the roof and found out how the head lining could be accessed to the point I needed. ........

So first you need open the roof and then stop it mid way so the roofs plastic front inner section is above the head rests or there abouts.



then chock it with something suitable to stop it rolling back down



remove the locking mechanism motor cover, this just unclips/pulls off with a gentle tug


inside this cover is a small T20 Torx screw that needs removing


Next remove from either side another T20 Torx screw , counter sunk this time, hidden just at the back and to the side of the inner plastic locking mechanism cover


finally remove the 4 x T20 Torx screws along the front edge of the plastic locking mechanism cover



Now just ease to cover and attached lining down onto the top of the headrests and roll hoops


now you will see the problem ........a thin plastic strip that is sewn into the liner screws to the roof frame, and this plastic strip cracks over time and come away from the fixings.



What I did was remove any fixing that weren't doing anything and drilled some new holes in the good section of the plastic lip and screwed the fixings back in. The frame has a tapered V section all the way across the fixing bar so you only need to drill holes in the plastic lip as the screws will screw in anywhere along the bar without the need to drill it. Just take care to only drill the plastic, as doing this in situ could lead to potentially slipping with the drill and we don't want any holes on the roof fabric do we !



I tried to drill the holes central to the plastic lip to give better strength , but when refixing with the screws you will need to push up from underneath the liner to get the screw into the V in the bar.



Once your all fixed back up


Simply refit the cover and all the screws, close the roof and remove your chock......Job done .

 
i have a small sagging sections on passenger side, this looks PERFECT for what i need to do, thank you :D
 
Done this earlier today, was really easy using this as a guide, would never have attempted this without this guide, so thank your taking the time to write up this tutorial :thumbsup:

Thanks for this

I just bought a 2.0 in really good condition with 65000km. However I noticed the sagging on both sides near the window so will now try and follow this advice though it seems really scary to do on my holy new car.
Some advice please:
1. I'm not entirely sure in which direction to pull or unclip the locking motor cover and don't want to crack it.
2. Any precautions for drilling into plastic? What kind of a drill bit did you use?

Ended up going ahead with the job. I bought a small handheld drill for the holes. A normal size drill would be impossible to get in there. The screw under the locking mechanism cover was really difficult to remove. It might have been stripped (because it turned but wouldn't come out), after a long struggle I managed to get it out. Complications included dropping a screw (which I managed to retrieve from the cavity area on the side under the hood), followed by the T20 tip of the screw driver that fell into the drainage area next to the roof! I managed to retrieve it with a magnet on a piece of wire. My clumsiness aside the job is done and one hopes the plastic will hold out a while longer.

I wondered if a type of u-nut could be made to fit and provide support to the plastic trim where it is fastened to the frame.

Thanks for the post, I am very relieved my first attempt on my Z4 seemed to work!

Wish he was still here so I could say thanks. This step by step tutorial is perfect!
Just got done doing mine. Had a couple of issues like the screws won't sit flat. Also, I managed to crack the plastic loop under the locking mechanism cover. So be careful not to over tighten.
I wasn't brave enough to take a drill near the hood so I just screwed them all back in and used some gorilla glue. Fingers crossed it will stay in place
