Every time I turn the headlights off they close and the left light pops
open. I turn them off and both lights close and the left light opens.
When I turn them back on the left lights closes and then both lights
open and come on as normal. Weird
Any ideas.

 

Yes, search there is a TSB on this. There are new parts (washers and spacers) that you install.

Here are the words:

There is a TSB out on this, here it is:

Good one DeeGee, I was just going to add your picture link (and give you credit) !

Hands accross the water (ocean) and all that !

 

Beat you to it

 

This EXACT thing happened to me last night! I manually cranked the left light for the cruise home this morning, the tail end of an overnite 350 mile round trip,,,,,didn't want to wink at any rustangs along the way. Got home, searched C5 tech, "headlights one up one down" and found this thread! I wasn't even surprised that the answer would be a few key strokes away!



GAWD I Love the CF!



Merry Christmas and or Happy Holidays Everyone!

 

I bought the washers from an online parts house and the 11505463 washers were over $3 each with with a $17 shipping and handling charge. Then, it took 8 days to process the order, ship and for me to receive the washers (NC to AL). I measured the washers and here are the dimensions:

Special washers to repair headlight winking problem 2mm thick x 9mm ID x 18.6mm OD


The most important dimension is the thickness.

 

Are you talking about washers or the bump stops?

 

Wow! $3 "each" + $17 shipping plus 8 days!!! You can get a "set" from Rodney Dickman for $2.75 and a flat shipping of $4 here.

You might need these as well (the rubber bump stops).
