So getting in my car this morning I came across a nice puddle on the rear passenger floor - luckily on my rubber mat so there wasn't much water damage to the carpet underneath - the leak is coming in where the rear passenger grab handle is, as the headlining is very wet around the grab handle and the light.
Front seems okay , are there any drain holes between the B and C pillars?

The headlining is pretty wet so looks like its coming in there then soaking/dripping down on to the rear floor mat.
1st time its happened as we got some heavy rain last night.
Are there any drain holes in the middle of the sunroof area I need to check?

So checked my sunroof and found the rubber seal is folding outwards, the when the sun roof is retracting to be open the rubber seal is folding outwards then not folding back inwards


I’ve also found a small tear in the rear seal, this is further back then where the leak is happening just past the B pillar could this be causing an issue -


Where about are the drain tubes located?

Just actually double checked what I thought was a break in the seal is just where the seal ends - its the same on the other side - so the leak maybe from where the rubber seal was turned up?

Are there any rear or middle drain holes to check?

what year of manufacture is yours

2014 L494 matey

don't the drain plugs run down the door pillars on that model

I think the front ones do but Im not sure where the rear ones are to check if there blocked up?

The drains run down the C pillar I belive so would think it the back quarter window panel and out through the rear wheel arches

Thanks
Is there anyway I can see the drain holes with the sun roof open?

The C pillar is where the headlining is wet - looks like its overflowing from the sunroof channel that pi55ing over into the headlining.

Just a quick thought do I need to remove the gloss black trim that runs the length of the car to access the drain holes?




That’s next to the outer silver trim?

you might have to I would of thought
I don't think they would run down the roof lining

Just a quick update on this looks like the slight leak I had into the head lining was due to the amount of rain that fell that day - very very heavy downpour, everything has been dry since in normal rain and driving through normal rain.
I’m guessing the water couldn’t drain away quick enough and was overflowing.

Always a good winter maintenance check to pop off the roof trim and check your drain channels , especially if you park near tress , leaves etc
