1994 UrS4 Side Mirror Glass Replacement

Sooner or later most UrS4/UrS6 owners find that their rear view mirrors have started to delaminate.  Why put up with decreased vision and an ugly mirror when a replacement heated mirror glass can be had for about $85 from your Audi dealer?

Removing and replacing this mirror is far from difficult but I figured it still wouldn’t hurt to put up a quick video FAQ on the subject.


Additional notes: On the later cars the outside mirrors were often a two piece design with a black plastic piece on the bottom that is held in with several screws. Many people find that removing this trim piece allows for easier access to the mounting tabs that hold the mirror glass in place. Naturally, this makes it less likely that you will break these tabs during the removal process. In my case, using the two tire levers and a small flat screwdriver made for quick removal without any damage but you may want to err on the side of caution if you tend to be heavy handed. 🙂

Decades of Duty… Tales of UrS4/UrS6 Daily Drivers

Decades of Duty… Tales of UrS4/UrS6 Daily Drivers

It is hard to believe that my UrS4 is now 20 years old. It certainly doesn’t look it, especially after a good spring detail. It also doesn’t look like it has covered more than 180,000 miles. In fact, it still does quite well in the regional car shows. This isn’t even some California cream puff. My car started life here in America in Michigan before coming into my care in Iowa (and now Minnesota.) All of these states have harsh winters and lots of road salt! My car survives!

I know several other friends here in the Twin Cities area that are still driving their C4 S4 or S6 as a daily driver as well. They somehow remain reliable enough for daily driving even after all these years. Amazing!

With that in mind, I decided that it would be fun to feature some of you who are still living with a UrS4 or UrS6 on a daily basis. I invite you to send me your ownership stories and photos to be featured here on S-CARS.ORG. Hopefully we’ll hear from people all over the world and publish some of their ups and downs of ownership.

Want to share your story? Simply email it to me at and include any photos of you or your car that you’d like to have included.

The C4 Audi S4 / S6 (UrS4/S6) Buyer’s Guide, 2010 Edition

Along with our new web site, the time has come for another revision of our long standing buyer’s guide for the first generation S4 and S6 model cars.

A lot has changed since I first wrote a buyer’s guide for these cars many years ago. Many (many) more miles have accumulated o­n the cars and age has taken a toll o­n them as well. Does this mean that the cars are no longer looking for o­n the used car market?  Not really! Quite the contrary in actuality.

Many of these cars are bargains these days as far as I am concerned. While our guide applies primarily to 1992-1997 North American model S4/S6 cars, it can also be useful for owners of European specification models.

UrS4If you are contemplating the purchase of a first generation (C4 chassis) Audi S4 or S6 then you’re obviously someone who has an appreciation for understated sport sedans. Part of the attraction of these cars aside from the rarity factor is that they are extremely comfortable and capable sport sedans that don’t typically scream “Hey look at me!”  They are also, for the most part, simple enough to work on for the average enthusiast.  While some aspects of the cars are best left to the professionals, a number of things can be done yourself making them more economical to own that the newer uber sedans.

Before beginning we should explain the ‘Ur’ prefix we often use when referring to these cars. Simply put, “Ur” is a German prefix meaning original. You’ll hear these cars referred to as UrS4/UrS6 or the original S4/S6. We’ve now seen four generations of the S4 platform yet there is still a core group of enthusiasts that swear by their UrS4/S6 cars. These cars are unique. Special. Limited production. Oh yeah, and they can be quite fast as well!

With that out of the way let’s take a closer look…
