Looks like I have a leak in the washer fluid tank - I'd filled up the fluid and saw a puddle next to the driver side door. And now there is no more fluid. From the top it doesn't look like you can see any leaks - but the problem is you can't see much from the top.

Anyone face this issue? What is the way to troubleshoot/fix?

If you remove screws 3 & 5 you can fold the inner wheel liner back to reveal the washer tank.

Thanks Royclark!! Will open the screws and see if I can spot the leak!

Looks like i might need part 13, 14 and 15 as potential source for the problem. Does anyone know the part numbers for these? or point me to where I can get these part numbers?

Opened the car again and filled the tank again with fluid. Now it appears that the water is dripping from the bottom of part #2 of the attached diagram. Can you please share part 2 and 3 numbers? Thanks much!

1K5955651 is the pump(#1) and 443955465 (#2) is the seal. The part numbers are stealthily hidden in the list under the picture. I missed it until just now.

Car is a6 c6 2.0tdi le mans avant Dec 2009. (system as in diagram posted above)

I also have a leaking "washer bottle" but it only seems to leak about 1 litre of fluid at a time after filling up but does so even when the car is stood on the drive. I have deduced that wherever the leak is it is gravity fed and having removed the wheel arch shroud and found no leaks on the bottom tank or pumps etc I think it is the seal between the top and bottom parts of the system. If this was the case it would explain the leak being limited to about 1 litre (to just below where the pipe from top tank goes into bottom tank) and it occuring when on the drive. I cannot see any water under the car so have no idea where it is running to. My question is - can parts 10 (grommet) and 11 (seal) be replaced by just removing the top tank assembly (no 8) or is it needed to remove the bottom tank to fit/renew part 10 (grommet)? Also is any sealant to be used when fitting the grommet to the bottom tank? Any advice appreciated.
