Greetings, everyone, I received the aforementioned warning on my 2016 BMW 218d Active Tourer, automatic. Upon taking it to BMW for a diagnostic examination, they indicated a fault code related to the torque converter lock-up clutch, stating that a new gearbox is required, with a cost of £10,000.My vehicle is eight years old with 36,000 miles on the odometer; there must be other solutions available. Any recommendations? The vehicle operates normally, and the warning indicator disappears for many days after the engine is turned off.
