I have a 2008 Panda with autotransmission. Recently when coming to a stop at a junction I have noticed the gearbox drops into N and the transmission light comes on dashboard with a pinging noise. The display reads no gear available. No matter if I try manual or auto, pressing the E button, switch off Engine it will not drive. Had it taken to garage that reset ECU and said the fault may return. It duelly did. Any ideas to what the fault could be? It happened several times previously but I managed to get it working by flicking the gearstick between auto/manual. Seemed to free itself but this no longer works.
