Engine light (O2 sensor code)
Engine warning light came on last week however mini (07) is running really well. Code P2626 (O2 Sensor Pumping Current Trim Circuit/Open). Garage replaced the O2 sensor (bosche). Ten days later the light came back on with the same code.
Taking into consideration the mini is running really well and it's just had a new O2 sensor any advice would be welcome..........
