Project Description

Make: Mini 

Model: Cooper SD

Mission: Diagnose battery drain fault and repair 


This customer came to us complaining that their Mini battery was draining and going flat for no obvious reason.  

Instead of simply guessing what the fault was, we analysed the car with a special piece of diagnostic equipment over night and found where the exact fault was. The fault could have originated from almost anywhere in the vehicle, but we managed to find it and repair appropriately. 

The fault was diagnosed and repaired effectively and efficiently without excess cost being endured by the customer. 


Cartronics specialise in BMW fault diagnostics, including battery drains. If you're experiencing any fault symptoms with your BMW, we can not only diagnose, but repair it at our workshop in Surrey.
