Hi team - HNY and all that!
So back when I did my last track day I decided to empty my boot of tools etc. into the paddock I had rented.. I then decided to go a little further and remove the dogs bed/boot liner/boot floor panel/spare wheel = race car lol
To my horror my battery and B&O sub were sat in about 1/4" of water!!!
I soaked it all up with paper towel, and carried on about my track day, but kept checking and there was always more spots dotted all over the place - rather than seeing one clear point of entry.
Over the last few weeks/months there's barely been a dry day (just my luck!), but having done some research I've seen this is quite a common fault caused by several potential failures:-
1. Pan roof drains (I don't have a pan roof - so its not this)
2. Rear light seals (all foam inside the light clusters is dry)
3. Rear air pressure vents - behind rear bumper (as per above - all dry around these areas)
4. Rubber seal around boot opening (no sign of water ingress)
5. Rear screen washer (no sign of water in the tail gate)
6. Rear screen seal (no sign of water ingress)
So the investigation gathered momentum and I gutted the entire boot, all trim/carpet etc.. and found there are 2x rubber bungs/grommets in the boot floor; to which I believe they are there to let excess primer escape when the shells are dipped in paint (!)
So I dried the boot again, then taped some paper towel over the grommets, and went for a 10 min drive on a day when it wasn't raining but the roads were wet.. and this was the result:-
Pretty sure both these bungs have failed, and the air pressure under the car is forcing them upwards and allowing rain water to spray around everywhere god knows how long they've been like that?! I've never had any condensation in the car, so would never have known had I not removed the spare.
Have ordered OEM replacements from Stoke Audi Parts (£12 delivered), and I think I will fit them with extra sealant... the bigger question is how did they both fail ???
I need another dry day so I can get under the car to see if all heat shield is all still in place, as I wondered if the heat from Scorpion exhaust had caused them to shrink/fail?!? Am grasping really haha
Oh well, lesson to us all here I guess.. check your rear bung holes regularly
