Default Headlight Washer Leak

I have a 2003 A6 and in the past day or so have noticed a BIG washer fluid leak under the passenger side front bumber. I can't see exactly where it's coming from, but it drains 3-4 quartz of fluid in an hour or so. I'm guessing it's something with the hose going to the passenger headlight washer. Is this common, and how big of a deal is it typically to fix.

Any help is appreciated. Thanks.

Default Re: Headlight Washer Leak

I searched the archives and discovered that it might be the headlight washer pump, but it looks like this is located on the drivers side at the reservoir. My leak is on the passenger side. Is there just one pump or two? I'm hoping it's just a loose hose or something small...

Default sounds like a loose hose...

you can pull off the grill around the fog light to get a better look.

my leaks have been from the washer cylinders themselves.

good luck!

Default Don't think this is uncommon

Had it a few years, ago. Hose fittings were leaking. Dealer replaced the hoses, under warranty, then.

Pump on driver side, passenger side probably hose issue.

STFA! No hose involved! If you don't know, BTDT, don't post your "sounds likes" off the wall ideas!

Thanks for the help. It sounds like it shoudn't be too costly of an issue. I may try to take off the fog light grille to get a better look, but will probably take it to the local dealership on Monday and have it fixed.

Default Just did this on my '03...

On the driver's side through. Mine was the cylinder directly under headlamp washer. I think it's a common problem. The driver's side, at least, was somewhat accessible from the top and through the cutout in the front bumper.

Part # was 4Z7-955-979 $61.65 at the dealer.

Default In cold weather (not TX) the cylinders can freeze/crack.

But sounds like either the cylinder or the hose to it is compromised. Another reason I 'deleted' mine...

Thanks. I'm actually in MO (just bought the car out of texas, no salt, etc.). I called the dealership and they think it's just the hose from the cylinder on the driver side to the unit on the passenger side. We'll fin out monday.

Thanks everyone for the help.

Default Not likely, inasmuch as there is no water in the cylinder when not washing. The plumbing thereto is.

rigid plastic pipe, not hose, with a mushy O-ring seal to the cylinder nipple. That O-ring is the failure point. Replace with Si caulk.

Default Ditto: Check the quick release coupling inside the front bumper >

its a little plastic clip (white) on the hose that allows quick disconnect of the hose when removing the front bumper for putting into service position. This may be loose or broken ...its a cheap quick connect and could become easily damaged.

Another waste of time suggestion, inasmuch as the QD coupling is on DS, his leak is on PS.

Default In your Opinion ... once it starts leaking inside the bumper it could run out anywhere

Think about it for a few minutes before shooting down any suggestion ... at least that's what I have found out in past experience when I ended up with my foot in my mouth!

Default Other factors to consider - are you parked on a level surface?

i have found in the case of these cars to not assume anything .....especailly with the flimsy *** connections in either tubing or wiring in these cars ..... very cheap stuff .... guess they had to cut corners somewhere.
