Sent my car to a Merc specialist for rear brake pad renewal today. They used the Star diagnostic computer to secure the SBC brake before starting work.
I noticed someting odd when the mechanic started the engine to test the car after pad fitment - a puff of black smoke. Another longer but less pronounce puff as he moved away.
After being informed that the car was ready; and on checking the instrument cluster I noticed the odometer showed blinking dashes instead of my accumulated mileage. When I informed the mechanic, he brought the Star computer out and tried to set the odometer again. He could not do it with the computer but got the diagnostic result with many "I"s response instead of all "tick"s. He gave some answers that I am in doubt of. He said he could only set the odometer to the old mileage reading with manual reset, which he did without my approval.
Being late for the day, I did not realise then that all accumulated readouts after the factory original reset have been wiped-out and all are set as per today's "after start". Worse still, I find the car average fuel consumption shot up from the previous 7.7 l/100km to 12.9 l/100km some 67% increase in consumption. On fast jabs on the throttle, puffs of black smoke emmitted. It never happen before.
What has gone wrong. What shall I do. I'd appreciate your explanations, help and advise before I confront this workshop soon. Thanks alot.
