I bought an '02 S4 Certified Pre-Owned from Stevens Creek Audi (Bethel Motors) in the SF Bay Area a couple years ago. The warranty, albeit withdeductible, and road side assistance to 100k miles was an attractive feature. I finally had to use the road side assistance, and Audi NA "customer care", and have found it useless! I had a flat tire in SoCal and tried to install the compact spare which came with the car. Problem was the spare was 4-lug and didn't even fit over the S4's front brake calipers to mate with the 5-lug rotor. Called for road side assistance...no help after 1 1/2 hours and I had to leave my car for another ride. After getting my flat fixed I called Audi NA "customer care" about the spare, and after 3 follow-up calls regarding my assigned case number I have not had a call back in 3 weeks! So still no spare tire. Useless I say!
