I pass on an unnerving experience from last Saturday evening when at a friend's place in a fairly remote country location. We were leaving after dinner and I started our 2015 Sport and could not select either Drive or Reverse. The transmission break indicator light remained on. We tried all the obvious things, replaced the 5A fuse, disconnected the battery, but nothing would clear the problem. A diagnostic warning "Gearbox Fault" was displayed on the dash.

On Monday the car was loaded onto a tilt tay and trucked the 140km back to the Melbourne dealer. Fortunately the driver knew about the neutral gear selector under the cup holders.

The diagnosis was a software fault, apparently triggered by releasing the electric emergency park brake before turning on the ignition. I may have done this.

I was not charged for the software upgrade and the dealer made only a modest charge for the three hours spent on diagnosis.

So in case you do not have the software upgrade on your RR Sport make sure the engine is running before touching that brake.

I have had this same problem on a 2014 Sport. Happened twice. I was able to shut the car off and restart it and it cleared the errror fault. Took it to the dealer and they updated the software.

Do you know which module they updated to prevent this?

I believe it was the module which controls the gear change, they did not replace the hardware, which would have cost about $1,800 AUD. I did ask to see the workshop diagnosis and the electronic messages (which the dealer showed me). I have been in software for fifty years and it had all the signs of a bug.
