Thanks @Raj1471!

you’re right. Yours is different than mine. So weird. If you get no water in your interior that way, then perhaps mine was ok, and it’s coming from somewhere else. It just happened to stop last night.

it would be nice indeed to see a facelift version of the weatherstrip. I’ll see if I can find a video online of someone opening their facelifted wagon to see if I can see the weather strip.

thansk so much!

You know, maybe mine is not supposed to be out at all. Maybe it’s supposed to be tucked in all the way around??

the upper section of the weatherstrip was out on mine, covering the gap. The taillight flange sat on top of the weather strip flange. Perhaps that was incorrect in the first place, allowing water to get under the weatherstrip and into the inside.

sure would like to see a pic of a facelift wagon

I've been looking at a few "walk around" videos of the facelift wagon and it seems I have it all wrong. The weatherstrip is indeed tucked in like yours, Raj. In fact, it seems that the weatherstrip "flap" is outside the gap above the taillight, then it goes under the black plastic guide and under the taillight plastic flange. Then, right under the taillight flange, it gets tucked into the gap.

I think that's what I see in this video and others.

Hold on a minute!

In this video of the 2011 version, you can see the weatherstripping flap is out, covering the gap below the taillight, with that angles section clearly visible. take a look and see what you think. I'm confused...

Two options as I see it...start a separate post specifically asking face lift wagon owners to take pics of the tailgate area or do a search for 2014 wagon for sale locally by dealer so you can...ahem..."kick the tires"...

great ideas, thanks!

UPDATE:

Just want to say thanks to all who helped!

After 3 weeks of on and off rain here in the Bay Area, the wagon has been totally dry now!

After seeing photos you guys sent me plus others I found online, it seems like Mercedes used different types of weatherstrips on the rear hatch of the S212 wagon. Some weather strips tuck into the gap between the fender and that hatch (Like Raj posted above), while others don't tuck into this gap. Mine was the latter design, but was inadvertently tucked inside the gap. Once I removed the strip and re-sat it properly, covering that gap, it's been totally dry. Amazing that this tiny detail can ruin an interior. Luckily I caught it before any damage.

Thanks again!
