topradio Posted February 1, 2017 Report Share Posted February 1, 2017 Andy, ever since you posted this image I have wondered if there should be a pipe between the two black 'grommet' like holes. If so I wonder whether some work had been done on your car in the past and the pipe left off. Link to comment Share on other sites More sharing options...
Andy Mac Posted February 1, 2017 Report Share Posted February 1, 2017 Car is going back in tomorrow - I'll ask the tech - I presume one (lower one?) is an outlet? I'll keep you posted ?? Link to comment Share on other sites More sharing options...
topradio Posted February 1, 2017 Report Share Posted February 1, 2017 Andy, It would be interesting to know what they were trying to show with this picture Link to comment Share on other sites More sharing options...
Andy Mac Posted February 1, 2017 Report Share Posted February 1, 2017 Indeed - my guess was the lower tube was the drain - that had been blocked and the "gunge" had come from the end of that tube / the filter that had been removed - I'll ask tomorrow ??

Andy Mac Posted February 2, 2017 Report Share Posted February 2, 2017 @topradio I asked the tech today - they are both drain outlets. (That's as far as I got). Link to comment Share on other sites More sharing options...
Simo_UK Posted February 9, 2017 Author Report Share Posted February 9, 2017 Right then to close this off - for the second and hopefully final time! Got my car back this evening and it sounds like the drain design is faulty and they are subject to failure/cracking. Carpets, seats, local electrics all removed. Upholstery dried out and Bose amp replaced (£500 + VAT alone!). Refitted and test. All in all without a car for 6 days. The drain is in post #11 here - http://www.planet-9.com/981-cayman-and-boxster-problems-and-complaints/115086-981bs-water-leak-seatbelt-holder-area.html And the outlet is the upper one in @topradio's picture above. At the point of outlet (by all accounts) there is a valve as opposed to an open pipe end. The pipe gets gunked up over time and the valve becomes redundant as the gunk now holds the water in the pipe/tray above. Turns out that the plastic used in the pipe/tray doesn't like standing water and also cracks. Cue water flow into the cabin. The new drain parts fitted are modified and the pointless valve no longer exists, giving the gunk less chance to build up. I'm not sure if this is a recent mod to the part or if newer cars had them fitted. It's not that easy to check either. Not likely to become a recall/campaign according to the OPC. Potentially a maintenance item though. One for older MY12 cars at least, to watch out for. If it wasn't for warranty, I'd be £3-4k out of pocket for the OPC to repair both sides after the leaks! Great service again from Portsmouth OPC again, including finding me a courtesy car when it was most needed (and a Macan Turbo too!) Link to comment Share on other sites More sharing options...
topradio Posted February 10, 2017 Report Share Posted February 10, 2017 How do Porsche do this? They manage to build in a problem that causes water ingress causing thousands of pounds worth of damage. They've been at it for 20 years and still haven't got it right. Almost seems deliberate ?

Why put a one way valve at the end of the drain pipe? If they were worried about water going up the pipe, the driver would have bigger issues as the car would be half submerged in water!!!
