Have my Phaeton (Bj. 2006, 3.0 TDI) not so long. However, I have the problem that the dipped-beam causes problems. It goes out very briefly and the error message comes: “Please check your light” (or so similar) It goes about 2 to 5x in a row. Then again 150km nothing and everything is fine. A false signal light is to be seen on the left of the middle monitor. When I turn off the car and turn it on again, however, it is gone. Today I was in the workshop to do a customer service, but it could not be read out. I was very pleased that the car master attested the top condition of the vehicle. But what that could be with the dipped-beam, he did not know. Yes, tonight it was again. No matter if with faster or slower driving mode. In the middle of the highway it went out and on several times after each other. (Good that there is still a fog light.) But still, now I am without a guess. Think me, it might be known that this is a problem and I know how to remove it.
