Hi , the orange engine light came on at 356miles , the handbook says exhaust issue drive to dealer . So van booked in @ MAN trucks , who then rang and said it’s ready , the lights gone out when we put some diesel in you owe us £20 for fuel and we have done bits and bobs ??? .Collected van asked what have you done answer. I dont know I’ve just started , ran for a few days fuel went low and lights back on again . So emailed service director @MAN said would ask a van technician , still waiting for a reply . Anyone have any suggestions or had this issue .
