Water in the car on headlining

[HPsauce]

If tilt works I'd lift it and have a good look. Might be debris blocking it somehow and even a bit of WD40 might help?
Or give it a bit of "encouragement" while someone else presses the button for you?

[daviesbike]

Ok still no solution ... car emptied about a pint of water all over my lap again.

I cant find where the drains come out can any one help. Or have a diagram would be hand..

On the W12 they come out into the door jam but on the lwb 4.2 for some reason they are blank .. no little pipe coming out into the door jams ?

[mannyo]

They do drain down that side, if its not in the door jam I think the end of the pipe is behind the wheel arch liner.

I was referred to the image below in another thread when investigating why mine groans slightly.

Thank you manny il give that a try ... the problems that water ingress can cause is unreal. Ive never seen anything like it ..

And the D3 is useless with out the mmi .. it dose nothing with out that brain to tell it what to do

[ScottD3]

I had to clean my drains out cause they was full up of gunk.

The passenger side drain is easier to do than the drivers side.

Jack the car up, remove the wheel, remove 6 or so T20 (might be T25) hex screws and gently bend the carpet look alike wheel liner away and behind the caliper.
You will see the drain rubber easy enough.
Open it up and remove as much crap as you can. be prepared for it to go down your arm and up your sleeve.

The passenger side is a little harder cause the washer bottle is in the way but you can move it out of the way enough to get some form of cleaning item in and remove the crud.

I got a bit of tubing and a funnel to help test the drain tubes. saved trying to gently poor water in to the gully around the sun roof.

[daviesbike]

All done .. Thank you .. driverside was a bugger as the washer bottle needs removing to get at it ... surprise surprise they were both welded closed ....

solution screwdriver right in there prodded around and then used a water vac to suck 3 lots of hot soapy water through to clear it all out.


perfect thank you



only other problem is major electrical as a result of this water ingress no mmi functions ... screen is stuck up and the thing gets as far as the boot up screen/welcome screen and thats it

lots of clicking sounds like a relay from the boot area but nothing


any ideas ?

Got in mine this morning for the first time in a week, and the drivers side headlining was wet as was the A pillar trim on the inside. Looks like my sunroof drain on one side is blocked, the rest of the interior was dry and luckily the MMI controls appeared dry. I've placed a plastic bin bag over the MMI controls for now, and parked the car the other way around so the drivers side is higher because the car is on a slope.

[mannyo]

Looks like both my front drains are blocked as a minimum, because I parked the other way on the slope overnight and after some rain I opened the sunroof. Result is the passenger side front gully is like a swimming pool. There is a very slow drip from the wheel arch where the drain is.

As I don't have access to anything to raise the car to get the wheel off, except the factory jack which I would only use in an emergency I decided to try and at least clear the passenger drain without removing the wheel. After 15mins of pfaffing around I decided its not possible, I removed the torx screws I could access and another 10mm bolt on the underside but was unable to pull back the liner sufficiently to even locate the drain by feel.

I'll have to get a local dorset garage to take a look and clear both drains, whilst they are at it they can fix my screenwash bottle as well.

For now I have covered the centre console in a plastic bin liner to keep the electrics dry if the level gets high enough.

I hope I can get it sorted quickly, as I need the D3 to attend my dads funeral (he passed away just over 1 week ago) and I don't want anyone travelling in the car to get soaked.

Decided to try the other way, got some wire and poked it down the hole from the sunroof end, got it all the way down to the end but cannot get enough push to get it to go through the rubber end. All thats happening at the moment is the wire kinks, so need a thicker preferably single core wire.

[Delboy]

Be careful if your using stiff single core wire, you run the risk of damaging the hose that runs through the car.

Did you try the bug spray bottle method I mentioned before.

Was successful on my drains and easy to set up
