I just replaced the battery in my 2001.5 S4 Avant over Thanksgiving
weekend. I was lucky enough to find one at a Casper, WY auto parts
store on a Saturday. The original went nearly 4.5 years. A quick check
of the electrolyte levels showed them essentially full - perhaps the
dealer had checked this at the regular services. I consider 4 to 5
years to be an adequate battery service life although not the most I've
ever got out of one.
On the windows gremlins topic - my sun roof sometimes closes right after
I open the back slot. This is annoying because I sometimes like to run
the feed to an amateur radio mag-mount antenna out through there - its
quite convenient weather permitting. On a couple occasions I've had it
close for reasons I'm not completely sure of - squeezing my coaxial
antenna feed line in exactly the way I'd hoped to avoid.
Another topic - does anyone else get the engine check light in cold
temperatures indicating an emission control seal problem when read on
the Vag-Com? Sometimes it resets itself, especially after re-fueling to
full. I suspect its just the gas cap loosing its seal. Should I be
suspecting anything more serious? Cheers.

Laramie, WY at 7200 feet 26 Deg F. below zero this morning - the S4
fired right up, but the drive train was a little on the stiff side on
the way to work.

If my experience is typical, then the battery won't be lasting much
longer. The cells on my stock battery were half empty after about 3
years. Refilling the cells revived it a bit, but that lasted only a few
I went out and got Diehard International. I had no problems installing
it. Getting all the plastic pieces off was the hardest part.
