well thats a worry as mine will be parked on the drive ( we don’t have a garage ) and its a very steep gradient. There’s no way I’ll be able to park it pointing the other way.Plummie2 wrote: ↑Fri Sep 10, 2021 10:04 pm I found water dripping from top of both windscreen pillars and interior mirror area soaking both front and rear carpets? checked all four drain holes by introducing water, flowed nicely away. Water ingress noticed shortly after our move to a new property which has a slight slope up to the garage. This change in the vehicle’s parking attitude made me think may be in heavy rain the rear drain holes were being overwhelmed, but the water was entering at the front of the vehicle , what was going on? On Googling I found information suggesting the pan-roof cassette was building up water at the rear section overwhelming the front drain holes forcing the build up of water to find another route i.e; front pillars and mirror, and because it was parked on a slope it also found it’s way to the rear foot wells. My answer to the problem, not a fix, turn the car round so it faces down my drive rather than up, this transfers the build up of water to the front of the pan-roof cassette allowing it to flow away safely, end of problem, well sort of, because I still have to remember to park this way if out in rain in a hilly area. I believe this is the real problem in the main, but of course blocked drain hole(s) will cause a similar problem on the flat and exacerbate a similar problem to mine. Just one other thing, if the pan-roof is 1 mm out of adjustment at the front it won’t help, when closing I give it a slight push to, I like to thing this helps? It is my belief Porsche KNOW what the real cause is, but to rectify they would have to introduce a new MODIFIED (probably used in late vehicles) cassette assembly to all effected vehicles costing the company thousands of pounds!!
btw, interested in your name. My dad was always called Plummie ( as was I by some people ) because of my surname. Its not a massively common surname so I’d be interested if that’s where you get Plummie from.
