I have a 99 A6 in great running condition and well maintained. All of a sudden I find a pool of water in the spare tire well. There are no apparant holes in the metal and I along with the dealer are stumped as to where it is coming from. Any ideas?

 

is the carpet wet at all outside of the wheel well??

 

seems just to be a pool of water IN the spare tire recess, rug appears to be dry

 

You may want to try washing the car and see if you can pin point water leakage.

 

been there done that

 

a common leakage point for water in trunks are the tail lights...have the dealer take off the tail lights (or if you want to save money yourself you can remove them) and just add more sealer and see if that helps

 

We had similar with our A6.
My husband suspected the rear wash / wipe was leaking inside the car.

My garage has told me today, that on initial inspection the wiper motor is turning round in the housing.
They say will be quite a big job (1.5 - 2 hours) to inspect inside the tail gate.

I can't understand why the motor would have broken loose.

This has probably caused the water supply to come loose.

Does anyone else have experience of this?
