i have a vauxhall combo 04 the engine management
light stays on all the time. i have taken it to the garage and they put it on the diagnostic machine and it comes up as nothing wrong. its been on the machine three times so far and the answer is allways the same.
each time they turn the light off but after about 30 miles it comes back on. can anyone please help.

Had this on a car (audi a3).Had diagnostic check 2 times.Garage changed sensor in exhaust area but light came bak on.They eventually changed the sensor for bosch one which apparently was what should of been done first time rather than the previous cheaper one.Light eventually stayed off.Hope helps
