A few weeks ago I had the drains cleaned and unclogged. Today, my wife took the car to a high-pressure car wash and noticed water dripping from the roof airvents. No water in the trunk.

What can cause this to occur? More clogged drains or another issue? Two pictures are attached.

When I washed the car last week there was no issue. The panoramic roof cannot handle a high pressure wash?

Any feedback/input is greatly appreciated.

Thanks.

Hello Mate,

I always wash my car with high pressure pump and never (thanks God) got a leakage.
How did you clean your front drainage tubes? May be something went wrong?

vanos, how exactly did they high-pressure wash the car?

if they spayed into the sunroof seal with high pressure for 10 minutes, its logical that something might happen.

when i have used the high-pressure washer on my car, nothing has happened, but i also use my common sense while doing it.

^^. It was an automatic car wash, not at home with a high pressure gun. The whole cycle is roughly 5-7 minutes. It occurred during the high pressure drying cycle, maybe it dislodged the sunroof seals and water infiltrated.

FYI, the drains were cleaned by a BMW Shop.

I will wash it at home again and see if I notice any infiltration.

I've been through an automatic car wash once (I hate swirls), with partially clogged drains, and this did not happen (or I did not notice as my headliner is black).

Re: the front drains, I personally think they are not related as these "vents" (I think these are actually the alarm system sensors) are above the heads of the rear passengers.

I washed the car today at home, all drains are functional and work properly. No water infiltration. I now suspect the high pressure drying at the automatic car wash to affect the unroof seals. I will monitor the situation.

you may want to check out this thread and potentially install the upgraded seal. it may help. unless you have it already on your car.

^^. Thanks, definitely worth looking into.

So, the wife took the car again to the automatic car wash. This time she opened the sunroof visor and noticed the high pressure water infiltrates from the rear of the panoramic sunroof. This tells me the rubber seal has dried up and needs to be replaced. Here are 2 pics, thanks for the tip mmtitev.
