Hello and welcome! I'm Billy and i will assist you with this.
Whenever a fault is detected within the shift paddles, this message is displayed, and the paddles will no longer operate. You're stuck in Auto mode.
If you turn the engine off, and then on, the paddles should work again (in case this was a software bug causing this).
If the problem persists, then you need to have the vehicle plugged on to a diagnostics computer, to retrieve the fault codes, and confirm the cause or culprit, and then act accordingly.
Most commonly, this happens as a software bug or glitch, which resets when engine is turned off and then on. In which case, and if the problem is not recurring, you have no problem.
Thank you for your trust! Get back to me if you need more assistance...Thank you in advance for the positive rating...http://www.justanswer.com/car/expert-billy/
Already switched engine off then on, no change. Its parked up for the night now so if its the same in the morning are you saying take it to an Aston dealer?
Indeed, as there may be a fault within the transmission itself, or a fault within the gear shift paddles. Only retrieving the fault codes will confirm, so you proceed accordingly.
Kindly get back to me if further assistance is needed.
