Water in the cabin Macan SD

[r1flyguy]

Hi all

Had a quick search but couldn't locate anything of use.

Any MSD owners had occasion to have to clear their sunroof drain holes and if so, how and what tools please, paticularly the rear ones!

I have sodden rear carpets at the moment and the windows all have ice on the inside following freezing overnight temperatures.

Any help appreciate.

The Panoramic sunroof cassette mechanism was replaced under warranty.

Not sure how that causes a leak but its been dry inside up until now.

Can't help in terms of tools needed. My Macan had a sunroof drainage leak into the battery compartment, not the cabin; all fixed under warranty by OPC - no problems since

Presumably this has now been sorted. My 2016 S has just had its 4y service and OPC have reported blocked rear drains for which they’d like the princely sum of £270 to fix.

All a bit concerning as we exist in a relatively benign environment.


Any words of advice/knowledge re this issue welcome. Thanks. M

Speaking about this issue to my dealer on Thursday, they confirmed that the Pano roof drains are checked as part of their service procedure to ensure they are clear. This I think may well be a recently introduced check for what appears to be a growing problem.
However, the key thing really for peace of mind is to ensure you go for the extended warranty which will cover these water ingress issues, the transfer box and any other problem which arise other than any consumable item, wear and tear.
A guy recently emailed to say he'd paid over £1600 to sort his leaking pano roof because he had no warranty, which included removing all the seats in order to dry the carpets - but despite this cost the problem wasn't resolved and the vehicle was returned to have the windscreen resealed but that didn't work either, so I guess it will have needed a new cassette with a new set of gaskets and seals, which apparently is the last resort fix.
Hope this helps!
Mike

Thanks spook. It would be interesting to determine what is the history of the issue and how different dealers are addressing it. As you say it appears to be a growing problem which has been acknowledged inasmuch as dealers are now including it as part of service etc.
My OPC is currently in the denial phase - an issue beyond Porsche’s control due to environmental issue. It would also be interesting to know if it was on the list during the 111 warranty inspection.

After a couple of stiff emails my CP has agree to sort it foc - as a gesture of goodwill. This after Porsche, apparently, had refused to fund it! As I said to Dan (cp) if Porsche’s position became widely known it would be something they would regret.

Anyway... just need to book it in which, to help mitigate their time, I’ll do along with the fuel pump recall work.

Hi Richard, i also have the exact leak problem did you ever resolve this?
My Macan has been back to Porsche 4 times in eighteen months but still leaks at the end of dashboard above the fuse box. Screen removed and re-sealed, sunroof repaired, roof rail replaced. Going back to Porsche in May for a 5th time with no apparent plan,????

Hi Richard, i also have the exact leak problem did you ever resolve this?

 

[cutter7]

Hi Richard,
I have exactly the same problem and area - leaking from the end of the dashboard dripping onto the edge of the carpet and water dripping over the front of the two lines of fuses! was this ever resolved for you? would like to know before i start stripping out the dash.. Thanks

Hi, sorry for the delay in responding.

Yes my water ingress problem appears to be cured. It has taken over two years to resolve with countless trips back to Porsche; endless e-mails; roof rails replaced windscreen refitted but the problem revolved around the panoramic sunroof cassette and drainage channels. This was first diagnosed on its first visit, but Porsche UK instructed the dealership to repair and NOT replace. It appears to have taken the threat of legal action and rejection (in December 2019) of vehicle to galvanise a response.
They tried in vain ?? to find a replacement vehicle with my specification, during which time the water ingress was repaired. It was a stand off as I did not want the vehicle back, I had no faith. But as a replacement vehicle could not be found despite my reluctant offer of further cash or upgrade: so I had my vehicle back. I am now back in love with it.

Best of luck Richard.

Hi Guys - my 2017 GTS suffers from the same problem, although it took several days of "watering" at OPC Leicester for them to believe me. It was booked in but that was cancelled due to the closure. Had a call this morning to confirm they are reopening on 18 May on a restricted basis and they are re-booking the cancelled appointments in priority to new bookings so it is now going in on 8 June ... we will see what the outcome is.

Thanks for your reply, i guessed this was the area to look at as the water was dripping from the underside corner of the dashboard as mentioned.

I have rodded these water exits each side of the sunroof cassette by using a length of coaxial cable but each side came to a stop at about the drop down to the dash board - also removed the wheel arch liners which let me get to two rubber gromets just below the dash, i was expecting a release of water to fall but they were dry behind? glad you got yours repaired.. thanks.

I had a similar problem last year. I was told by the independent dealer that sold me the car and a Porsche specialist that blocked drains were the cause of the passenger footwell filling with water. In the end I asked the independent to leave the A pillar trims off and tied tissue paper around the pipes which identified that the leak was from the sunroof. Eventually after being told several times that the leak couldn't be traced I removed the grab handle and sun visor and poured water into the pano roof drain channel and filmed it pouring into the roof space. It's frustrating having to self diagnose problems but in the end the local OPC resealed the sunroof tray and contributed to the cost.

 

[cutter7]

So far no leaks.. all dry inside since mid summer, rodding the drain holes from each side of the cassette using coaxial cable (push firmly down to the dashboard level many times each side) and completely taking of any residue from the sunroof edges including glass closure and lubricate the spring mechanism with wd40.
We have had many downpours since then and the passenger carpet is now always dry.????

My Macan Turbo is back at Porsche with this issue again passenger side footwell! Pan roof drains apparently.....

 

[Dandock]

Since the ‘fix’ in early summer I’ve had no further problems despite the current weather. I’ve no idea where I read this but remember someone commenting that the issue was caused/exacerbated by a kink at the base of the drainage tubes(s). The simple fix, apparently, was to cut off the tubes(s) just above the kink.

 

[christopherryan]

If it keeps happening its probably the tray leaking. The drains can block but the tray can also debonair from the roof and needs dropping at the front to reseal it.

 

[stuartclarke]

Update. Called my OPC this morning to book in my 4 year service and was informed that a pan roof drain clear is now a service item. If the drains are blocked and you have a water leak into the cabin or boot then you may not be covered by the warranty. Apparently there are drain points at the front, rear, and doors. The cost was an additional £439! As I keep my car in a garage I declined .... I would be interested in any other updates on this potential issue.

Not Porsche but same stable mates in the VW group. The issue is related to the pano roof cassette leaking same one used as far as I know within the group. Mine was on my L& K Yeti( second one ) which was bought from a main dealer with a 1 year warranty a couple of months after owning it water appeared in the driver foot well soaked carpets ,returned to get fixed and told as the fault was not covered and would cost me ,as it happens the car was just months out of the 3 year warranty and the paperwork I got with the car showed a cassette bill for £950 was claimed under warranty , I was wondering how come as the car did not have a cassette fitted ,so then I found out what it was, so evidently had issues in the past so armed with the evidence I said I was not paying for a previous fault ,it took a bit of time to be resolved, but after a few failed attempts it was fixed ,fingers crossed has been dry for well over 2 years and no cost to me .My brother had a used main dealer BMW X5 same issues and after 5 attempts rejected the car .I think if buying any car will avoid the Pano Roof ordinary sunroofs seem to be fine it is the size of that cassette is the issue .

Hi guys, I’m speccing a new GTS and can’t decide whether to include the pan roof or not due to issues I’ve read around leaks. How much of a problem is this? I’m not that bothered about a pan roof but I’m told nobody wants to buy a used one without a pan roof. What’s the general consensus on do they leak and is it an essential spec item?
thanks
