I'm just wondering if anyone else has experienced this. The problems of leaking sunroofs is well documented on this forum and elsewhere but so far (touching wood) I've been lucky and not had this problem. Usually the car is garaged under a car port with a 6' fence down the side so reasonably well protected from inclement weather. But this week we are on holiday in the Peak District so it's parked in the open. And we had a ferocious storm a couple of night ago with thunder, lightening and torrential rain. I went out in the morning fearing the worst and there was a small pool of water sitting on the rubber mat in the passenger footwell but the headlining was bone dry. We had more rain yesterday but no more water so I'm wondering whether it was just the sheer intensity of the rain forcing water past the front passenger door seals? It wasn't a lot of water - less than half a cup - so I was able to take the mat out and pour it away. 

With still plenty of long term owners on the forum and a good number of former owners looking in I just thought I'd ask if anyone else had experienced this.

I did have this on a previous Audi A6 where the roof was sound but when I got to the autumn, tiny bits of leaf foliage and dirt had blocked up one of the sunroof/ bulkhead drains and in heavy rain it was enough to 'burst the bank'. Just footwell, not headlining. Used bike brake cable on Audi to gently feed through.

i gThanks for that. I'll try the bike cable when I get home. Hadn't thought of the bulkhead drain but I did have to clean that once before.

No problem. I had to do the Audi each autumn. Just remember to be careful as the plastic pipes can get brittle / fragile with age.

..you don't necessarily get wet headlining....I didn't on mine. Mine had a partially kinked drain tube (front passenger side). This led to an occasional "drip" at the bottom of the door pillar, and the headlining was not damp at all as the water had basically "overflowed" due to the restrition and then run down the outside of the drain pipe and then down the lower part of the door pillar onto the passenger carpet, (a few drips were clearly visible inside the car).

 

This only happened on the odd occassion (ie not every time it rained...may have been "volume" related?).  I got my local indy to remove the headlining, replace the defective (kinked) drain pipe, then "glue" all the other pipes on...

Thanks Stubod. I'll bear this in mind if it becomes a recurring problem - we've had quite a bit more rain since the tottential storm but everything still seems OK so I'm keeping my fingers crossed. 

..my guess would be caused by a high volume of rain, drain pipes may be partially blocked / unable to get ride of all the water, so some water escapes somewhere else.

 

May also be dependant on the "angle" the car is parked at?

 

Mine only did this (leaked) on a couple of occasions, and there where a few drips evident on the lower part of the passenger door pillar. .

 

It may be worth taking the fuse cover off as this may show some signs of rust on the frame around the fuses...(did on mine but very minor)......I wish you luck!!

Thanks Stubod. When I got home I used a watering can to poor water down each of the four drains below the windscreen and then into the channel around the sunroof and got a decent stream of water out of each of them. So I think you are right - it was just the sheer volume of water; it was quite a storm that night but a couple of nights later we had prolonged heavy rain (but nowhere near as intense) and there was no sign of water in the footwell the next morning. I'm going to mark it down to exceptional conditions and not worry about it.
