I have a complex problem. I have a 2011 Audi A4 with 43,000 miles, which I have loved. Two weeks ago I was driving to an appointment when I heard some loud beeps, and the rectangular square on my instrument cluster went dark. I brought it to my local Audi dealer, and they said that I would need an new instrument cluster at a cost of $2,200! Wanting a second opinion, I told them not to do the work because I wanted a second opinion. Astoundingly, when I went to pick up the car, the instrument cluster came back on perfectly. I continued to drive the car, but in a couple of days it went out again. I brought the car to a local mechanic who I trust, and he suggested having the instrument cluster sent out to be rebuilt, so we tried it. After sending it out, the rebuilding company responded that the instrument cluster was working perfectly and didn't need to be rebuilt. My mechanic reinstalled the instrument cluster, and it's now working, but we expect that it's going to happen again, and they said to bring it in when it fails again. Have you ever heard of this problem?
