Hi All,

Please can someone tell me if the interior roof liner for a 2001 SLK R170 is the same or will fit a 1998 SLK R170?

Recently, I've noticed a slight air bubble across the back end of roof liner. The roof liner is the original that came with car and is layered with some fabric or vinyl possibly. I was told it better to get a new one that try to fix the one in car now as the problem may come back in future.

Thanks for input :)

Hi @slkclub

I'm pretty sure that the preFL and the postie are interchangeable although I haven't tried that myself.


Replacing the existing headliner material is an easy and rewarding little exercise - IF the only problem is that it's sagging due to the old glue giving up the ghost. It's a totally different matter if it's soaked in hydraulic fluid due to a leak from the roof hydraulics. I've replaced two now that have had the notorious air bubble, neither of which have had further issues since then :tu:

Hi @M4rCu5

The headliner is sagging due to old glue. I'm not sure what kind of glue with hold this up properly and for long. The summers here are getting very warm and headliner took a roasting from the heat this past summer. Luckily, I've no hydraulic leaks to worry about. I'll be grateful for your guide to fixing this headliner air bubble issue.

I ran mine without the liner for a few months so I know what you're saying re. heat from the roof destroying the glue. There is quite a bit of heat (lots actually) coming through there as it's only thin metal at the end of the day. I also happened to notice just how much noise came through there without the liner.

So ... first stage was to dampen the noise with some heavy duty sound insulation that I happened to have kicking about, this had the added bonus of suppressing the heat as well - pretty much the same job as the original liner does - in effect becoming a new 'primary liner' if you like :surprise:

Both of mine have suffered from the air bubble and in both instances it has been due to the liner and foam parting company from each other rather than the liner and foam parting company from the liner board. I imagine the fix to be more or less the same with the difference being to use a foam-backed material or not.

Full photo instructions in the thread that was hilighted earlier, click HERE and go to page 2, the trim adhesive that I use is Trim Fix which is a temperature resistant upholstery adhesive spray and comes out like 'silly string' (other brands are available). This on its own should be enough but coupled up with insulating the roof as well should ensure no sagging ever again .. we shall see :)

Hi @M4rCu5

Once again, thanks for your useful contribution. I'd taken the headliner off to inspect it and issue is the form between the fabric/vinyl and the headliner board coming apart. I don't want to get the same problem again if I just replace the current fabric/vinyl with another foam backed material. So I'll scrape off the foam on both, give it a good clean, let them dry and glue them directly to each other. I believe this should suffice, I've not had any noise issues so giving the foam a miss probably won't matter much. I've ordered a high temperature Trim Fix adhesive from eBay and will take care of fix this weekend.

The foam just gives it that extra 'soft to the touch luxury feel' but yeah, it should be fine without it. I'd at least consider getting a new fabric/vinyl to use though, you only need 1 sq/m. and you could run into problems trying to use the old stuff.
TIP: Don't spray the fabric. It says on the tin to do both surfaces that you're gluing, do both and you'll end up in a right old mess, ask me how I know :) - you only need to liberally spray the board and let it go off for 5-10 minutes before applying the fabric and rollering/brushing/kneading/coaxing it into place :tu:


And here's the other one .. pimped :grin:

The foam backed is nice but it makes it a little trickier to fit due to the minimal added thickness. Yes glue on both sides makes it interesting. One thing I did after smoothing new liner with a bondo spreader, was to fill a bunch of zip lock gallon and quart bags with sand, and lay them on the liner overnight for better adhesion.


Liner is reasonable but the shipping is a bit much. Many sources.

Hi @M4rCu5

Nice!
Very good advice. I was just thinking about that yesterday when I got my Trim Fix from eBay. I'll be getting some new fabric and doing this job on Saturday. Thanks very much for advice and guide
