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

IMG_0175It 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.

Not Your Everyday B5 S4 Biturbo… Could Be Yours?

Not Your Everyday B5 S4 Biturbo… Could Be Yours?

Enes' RS4 conversion

Enes’ RS4 conversion

I first met the owner of this car, Enes, back in 2009 at a local car show at one of our local Audi dealerships.  I remember him as being a very friendly if not somewhat soft-spoken guy who just happened to own this uber stunning looking S4 Biturbo.  Of course, it wasn’t just an S4 Biturbo… it had been given the full RS4 spa treatment including those oh-so-nice fat fenders and all.  Have mercy!

As it turned out, Enes had actually purchased the car from the second owner who didn’t drive it all that much.  Enes doesn’t seem to drive the car all that much either having put only 3,000 miles per year on the car since buying it.  Anyhow, the original owner of the car was in New York state and had a body shop, so the RS4 body conversion was done under his watchful eye.  Having seen the car up close I can also tell you that it was done exceptionally well as well.  This is what S4 Biturbos SHOULD be like.  They should hurt you a little bit with their beauty while still having a bit of that stealth factor intact.

Admittedly, Enes’ car has lost a bit of that stealth factor.  It looks mean.  Menacing actually.  It isn’t the fasted Biturbo S4 in North America but to most that doesn’t matter.  This car looks as if it could frighten your neighbor’s dog just by sitting in the garage.  Seeing it on the road is even more impressive.  Then again, I’ve never once seen the car dirty which makes me think that perhaps Enes would be a candidate in an O.C.D. treatment program (but then I’m afraid I’d have to join him).  Actually, he’s one-up on me as he doesn’t drive his S4 in the winter while I do drive mine.

It was a bit surprising to hear that Enes is actually selling his car.  After speaking with him he confessed to buying a couple of Porsches and that the S4 had simply been sitting in a secure garage waiting for attention.  He stated that he didn’t really need to sell it but really thought it might be best to have the car go to another hard core enthusiast who would drive it more frequently.  (I’m pretty sure I’d drive the wheels off of it myself if it were mine!)
