    Why is my 2015 Mazda BT-50 losing power?

    Mazda Mazda Advice Mazda BT-50 Mazda BT-50 Advice Mazda BT-50 2015

    Why is my 2015 Mazda BT-50 losing power? It happens after driving for four hours off-road. I will be driving home and it will slowly lose power, struggling to accelerate. I disconnect the battery and the car is fine again, then slowly loses power. Intercooler hose is not split, no warning lights are on and has recently been serviced.

    You can probably rule out anything like a split turbo hose as this would cause the vehicle to lose power all the time, not just after prolonged use. Modern turbo-diesels like the one in your car use a range of electronic sensors and controls to keep everything running properly. It could easily be that a sensor is sending erroneous messages to the computer. An electronic scan of the vehicle should offer some answers.

    The other possibility is that the fuel system is not keeping up with the engine over time. This could be due to a blocked filter, a blocked fuel line or return line or even a fuel pump overheating. A check of the fuel system would also be in order.
