Bmw 730li 2012, Wet carpet rear passenger side, can someone help me with this please or point me in the right direction?

[Manny 1]

Hi everyone, I new to this forum and I am having some trouble lately with my 730li f02. The rear passenger side carpet gets wet when it rains or I wash my car. Got it checked at BM workshop but they couldn’t find a solution. They dried the carpet and foam and water tested both doors on the left side for vapour barrier seal leakage, but no luck. It is stil the same. Any help with this would be appreciated. Please let me know if someone knows a fix or where I can get it fixed.

Possibly blocked sunroof drain is often a culprit

If it’s anything like the e39 or e92, it could be the door vapor barrier. 
To check, pull the door card off and check to see the seal is still bonded all the way around.
There will be plenty of detail online on how to remove the door card and how to replace the vapor barrier.

Thanks for your response. They tested it, but it was fine.

Thanks for your response, but it was water tested and no issues were found. Anything else could go wrong if you can think of?

Get in the car with a high-power torch and get your wife / girlfriend / significant other to spray the car with a hose pipe on full flow. 

Try all the suspect areas, door, sun-roof, etc one at a time - for a good period of time, minutes not seconds. Hopefully the torch will show up some drips that you can then follow back to the point where the water is getting in.

I just add another one in a hope to save TS's time... and water

the water is coming from steering cover in front left due to blocked in front drainage,its common in F02 and F10.
