Major water ingestion into my 991 Coupe.

Hi all,

I'm in a spot of bother with my 2013 911.1 C2S. The car has 34000 miles on the clock and up until now has been in a mint condition, or so I thought.

On Saturday, I jumped into the car to drive somewhere. When I turned the key and started the engine, I got a yellow warning on the dash saying something like "auto stop-start function disabled". As I was in a hurry, I thought "oh well, I can live without that so I'll look into it later". As I started to drive I hear the sound of water swashing around somewhere in the car. I quickly placed my left hand on the floor behind the passenger seat and boom, my hand was soaked in what seems to be fresh rainwater.
I then realised that my radio wasn't working either (PCM seems fine, there is just no sound coming from the Bose speakers). I quickly turned around and parked it back on my drive. I was shocked when I found that my wet and dry vac had to be emptied about 4 times just to suck all the water from under both front seats.
As it was midday on Saturday, my OPC service department had already closed till Monday. I could not knowingly let the car sit with wet electronics until Monday, so I decided to remove the seats and any electronic control boxes I could find. All of the control boxes directly under the drivers and passenger seats were completely submerged. Water had gone into the parking sensor box, but miraculously, no water entered a large box which seems to be a BCM controller. From what I can work out, it controls all switches in the car and various other things.

However, the Bose amp under the driver's seat is completely gutted. The alarming thing is with that component, is that unlike the other boxes, the Bose amp has significant corrosion and even a water line which seems really old all around the amp's enclosure. The PCB is completely shot. I am surprised it had worked this long!
I have not found the leak yet. I've checked all the usual places, including the sunroof, but it's all bone dry up there, with clues of dust, so the water didn't come from there. I did hit a large puddle of water on the previous Tuesday, which is the only thing I can think could have caused this. This post isn't to try and find an opinion of where the leak is, I will have to sort that out myself or maybe the OPC.

The car's Porsche warranty expired on 20 Feb 2019. I have a RAC Platinum warranty that expires in November so Porsche wouldn't allow me to extend the warranty in Feb as they say I'm not allowed to have two warranties on the same car. The RAC warranty has already authorised a fix (within about 5 min of calling) to the front shock absorber or mount (we don't know which one is broken yet), but they will allow claims of up to £5k.

My question is, do I carry on drying my car without the OPC or do I dry it as best I can and then take it to the OPC?

Another thing I'm really struggling with is, how is it possible that a car that sold for £85000 6 years ago can suffer such a major issue? It's totally unacceptable, but I love the car so much, I can't even think of getting rid of it. I just don't know how to proceed. Someone (me, or the RAC) will have to fork out £736 for a new Bose amp at the very least.

I'm not here for sympathy. However, to say I'm completely gutted is a massive understatement. I waited 18 years to be able to afford my first Porsche and now 7 months into owning it, I'm having to deal with this. It's a first world problem, I know, struggling with a Porsche, but having to work 15 - 18 hour days to afford what I have and then having it ruined like this, is just gutting.


Any thoughts on where to take it and how to approach this? I'm in Lincolnshire and I normally use OPC Cambridge.

Thanks for reading

Well, now that was disappointing.

I just got off the phone with OPC Cambridge. I explained what happened. All I got back was "well, we can book it in for the 5th August to try and find the source of the leak". Not "Oh wow, that's a terrible thing to happen to a car made and sold by our brand". It's like, yeah, well the car is yours and so is the problem. I guess a Porsche specialist it is then, as the dealer doesn't seem to give a damn.

Sorry, rant over.
 
I used to own a 2014 991 Targa 4S which I bought in June 2015 with 7k on the clock.

I had had exactly the same experience in the first 3 months of ownership. Porsche Reading sorted under warranty. The whole dry out process took some two weeks whilst I had a loaner 991 carrera 2 convertible.

The cause of the issue, the dreaded pipework from the A/C unit that drains out through the car to the outside had become disconnected. All because a 50p circlip not fitted. I insisted it was on repair to ensure never happened again. It could not work loose. Not a snap connect it seems.

I caught the water ingress very quickly so no damage to electrics.

I tried in vain the get new seat locators/sliders ( the metal showed the water damage) but could not swing that under the warranty.

Historically leaky A/C units have been an issue and I was aware from my 986 Boxster days. So it’s a case of being on the ball I’m afraid. Despite being assured this issues from 2000’s have been addressed.... clearly they linger on.
