Hey all,

Just picked up a Mugello Blue 08 RS4 cabrio. No stranger to Audis, since ive been going through quite a few of them lately. No, not beating them up.... just enjoying all the models....

Couple questions:

1- I noticed that my speedo is reading about 5mph too high. I verified this with a roadside radar (displaying "your speed is.."), GPS altimeter device on my IP4s, and the old fashioned time/distance method. I'm running stock tires- 255-35-19. Anyone else have this issue?

2- On the cabs, is the push-to-talk button on the right front of the multifunction steering wheel non-functioning? when i push it while my iphone is connected, nothing happens. Is this a cabrio-specific spec?

Other than that, I'm enjoying this car!

1. pics pronto
2. speedo reads high. Normal on most every car on earth (they would rather over state than understate your speed is the rationale. 5 mph sounds high though...mine is off 3-4 ish at high speeds. Less down low.
3. that should trigger bluetooth...does the car have bluetooth? Does it connect etc when you get in? (BRRRINNGG! sound)

In terms of the PTT button, this functionality is disabled in Audi convertible models.

At 80mph mine reads about 6-7mph high, but I have 275 series tires with lower profile ratio. They look about the same thickness as stock but I'm sure the tiny bit of difference is more than enough to affect the speedo.

The 275/35/19 tire is going to give a speedo reading of 2.089% higher than the stock tire size.
It seems everyone's speedo reads high. I don't like this because it is putting more mileage on the odometer likely, by about 10% by what people have been posting here and elsewhere.

oops, I meant 5-6% higher from most reports, mine is about 9-10% higher.
