Macan Water in drivers footwell

[Shiverman]

Hi All,

I hope someone can help - I went out to my wife's car this morning and found a puddle on the driver side rubber floor mat.

Does anyone have any suggestions or ideas of where to look for the ingression? As I drove the car a few drops of water fell on my right foot, but I couldn't feel any dampness when I got home and placed my hand under the lower dash.

Lifted the bonnet and all is clean with no leaves blocking any holes.

We have had the car (a 2017 mode Turbo PP) for 6 months and this is the first time this has happened.

Any thoughts suggestions or similar experiences would be gratefully received.

Thanks in advance all.

If you bought from a centre and have Warranty get it into an OPC, the sales check will have included a drain inspection - they are also checked at Service as part of the 2yrly Status Report. Most likely culprit is the Panoramic roof (if fitted!)

Hi Pope, thanks for your reply.

I had the car in for its 4th year service in early Jan as the warranty ran out on the 15th Jan. I didn't renew the warranty as tbh I am not sure how long we will keep the car. 🤦‍♂️

I will call the OPC but my guess is that they will say they checked at the service and all was fine so we will now have to stump up the bill for a repair.

And yes it has a panoramic roof and that seems to be the issue.

As per Neil’s comments, this is a common issue in Cayennes as well as Macans. There are additional drains located behind the arch liners which can get blocked with crud

There are quite a few videos on YouTube about the blocked drains and how to clear them. I did mine on the first day of getting my car as there was a bit of sloshing coming from the nearside sill and managed to drain a fair amount onto the drive. Some chap has a video of clearing them using one of those annoying car flags...

Couple of threads on the MacanForums about this issue and more specifics about how you can fix but I wouldn’t suggest a specific trip to the OPC for this one, I sorted mine in about 20 mins on my drive.

Thank you all for your replies, and if you can send me any links to repairing it myself I will happily give it a go.

Drivers side headlining is damp and water is coming out from the bottom of the A-pillar into the car AND when I our water into the sunroof drain hole also through the drain hole under the car. Passenger side - when I pour water into the drain hole in the sunroof, water is coming out the bottom of the A-pillar into the car and out of the drain hole as well.

As the water that is coming out of the drain holes underneath the car is significant, I guess there is some disconnect of the drain tube or it is split? Is this possible or common?

Drain holes are clear when you open the sunroof and have no dirt or gunk in the channels. I put a thin plastic tube down the drain holes but I could only get this to go as far as the bottom of the A-pillar.

Any videos or links so I can try the next stage would be welcomed.

Get it booked in and inspected; press the fact the Warranty only ran out 2wks ago and look for a Goodwill contribution - it's not an isolated case. If it's coming through the roof cassette it was always like it.

Thanks Pope - It will be a call first thing in the morning.

Appreciated thanks - not such a big problem to get over if occurs

I’ll post once it’s sorted and let you know how I get on.

Hi Pope can you let me know where in the status report they’re checked.
Actually didn’t get a status report back with this service!! But I’ve looked at the previous service reports and couldn’t see anything.

Hi All

Thanks for all the input and I got feedback today from my local OPC. Apparently the drainage ducts were blocked and backing up so they snipped the release valves at the point they exit the car. They reduced the labour rate so the bill was £200 which is high enough but at least the car is sorted and dried out now as well. Let's hope that it has cured the problem when I pick it up.

There is a specific point, 'check water drains are not blocked' on the document - if the check reveals any issue the remedial work is chargeable.

Sounds like you had a good result.

A shame I didn't get the check report when they serviced the car !! Is it chargeable even if the car is under warranty - I guess it would class as fair wear and tear?

Is this covered under Porsche Used Car Warranty?

You'd have to check and see what they say. I had let my warranty expire by a month so it wasn't covered. I think the OPC were pretty fair imo and the charge was reasonable and they did a lot of work ensuring it had sorted the problem.

Fortunately I caught ours early enough that we didn't need to seats and carpet out to dry everything as that would have been expensive.

Still took a good week til everything was properly dry and it had a couple of days in my garage with a Dyson heater trying to dry it out.

I was told not a manufacturer defect so they sorted under goodwill within the 3 year warranty but wouldn’t be covered by my now current extended warranty

TBH they are in a bit of denial over the problem. At first my dealer were that’s unusual but in the end they admitted it happens a fair bit.

There’s a lot of info on the forums that you can always use as leverage for goodwill from Porsche as it definitely isn’t an unknown issue.

I hope I don’t keep the car long enough to have the issue again and it makes me think twice about have a sunroof as well.
