Hi,
I have just received the two vents I ordered from CreweAudi (thanks)(
Many people might have a "fishtank" instead of a battery compartment and so I thought it might help to show the cause.
Firstly the vents are behind the rear bumper and it has to come off to repair/replace the vents.
This is where they are shown by the red square (they are on either side at the rear)
This is what the vents look like off the car
This is in the normal position and the grey inside the squares is very flimsy plastic that keeps condensation out but allows air OUT. If you have ever owned an old style VW Beetle, you will know that the doors are tricky to slam unless you open the window to let the air rush out. This design means that you can slam the doors and the air can escape and yet it does not let water / moist air, IN.
When turned upside down you can see that the flaps flop open (they are VERY flimsy plastic much like the thick material used on heavy duty bin bags / rubble sacks.
This is the shot from the "inside" view of the vents
The main reason for the leak is the (equally flimsy) seal tends to get dislodged when you have a rear shunt or if the bumper has been replaced for any reason. They clip into the body and the clips are not fantastic.
Sometimes the vent cracks.
The temptation is to drill a hole in the battery tray floor, but that doesn't work because there are several low spots and so you would need several holes, and in comes the moisture again.
The two vents cost me £42 from Crewe Audi and much better than trying to repair the existing ones Part number 4A0-819-181-A. The sight of the compartment filling up again after all of that work is such that the £42 is money well spent!
I have asked for this to be added to the "How To" Index thread for future members to find (Well worth a read if you haven't discovered it yet)
