No DSG here ! Basic jetta, no turbos, no superchargers, no flappy paddle gearboxes.
It did it again tonight, I had the MRS in the car and she spotted 'NO TP' on the radio. So we pressed the TP button to turn off TP.
I read the manual, and TP is traffic program. So this may be the "Bong" sound, telling me there is no Traffic info, and the changing of the station is its attempt to change over to the Traffic report.
I wear polarized glasses so I could not see anything on the radio earlier today.
