Re: Blue and Me Ecodrive Working in T Jet !!!! Whooop dee do I have BnM 5.4 on my Punto and when I put the USB in the car, it says updating and then says USB error 10. r some google, this seems to be a problem with EcoDrive as its not compatible with 5.4 yet. Any thoughts on this guys? In the EcoDrive on PC, I selected country as UK and car as MJD 1.3 76 bhp.
