Problem with the 8-speed automatic gearbox in some BMW 5 series vehicles
Posted: Thu Feb 26, 2026 8:06 am
Hi
Need some advice, please. Last week, my 2015 5 series lost all gear options and entered limp mode. Keep getting the "drivetrain malfunction" message. Got it into drive, but it chugged along at 5 mph with no power from the engine, as if the clutch were barely biting.
The main dealer has been insolent and has recommended a brand-new gearbox costing £10k as a remedy. I will avoid that choice at all costs. Throughout my time as its owner, the car has never broken down on me. I did receive an alert on my app indicating that the starter battery life is running low and needs to be replaced. While the vehicle was with the primary dealer, something occurred. Is this going to be sufficient to cause the box to display an error?
How about we begin? Does anyone have a clue? Your assistance or recommendation is much valued.
Much obliged.
