Roman: I took my audi to a dealer. They read the computer there were 3 faults:
1. the motor mount sensors were giving a crash indicator and appeared to be compressed. They said this was not critical. They gave me a code of -P1577 Right Motor Mount Open (not sure if that was the error code or their estimate code)
2. The "Right MMI Switch Panel" was not working (the car button is not operable) and needs to be replaced ($754.56 for the MMI Board (part #4E1 919 612H), plus $456 labor. They gave me a code of 00457 - Vehicle MMI Button Stuck.
3. The recommended replacement of the Suspension Compressor ($1625 parts and $216 in labor). They gave me a code of 01772 Level Pressure Sensor Too Low.
I had the oil changed, filters, etc. After they returned the vehicle, it appears to not be in "squat position" any more. However, the MMI Car button does not work and the suspension no longer adjusts when I hit 75Mph for an extended period of time. Which I really dont care about with such a high mileage car - although I did enjoy the performance associated with that feature.
It's ironic to me that the Suspension Compressor and the MMI button would fail at exactly the same time. Is the MMI button something I can resolve myself? Any advice?
