hi and thanks for taking the time to help,i have two warning lamps on my dash ,booklet says exhaust emissions light for one and esr for the other i have had the car into the garage and have replaced the air mass meter and two connecting pipes also fitted new air filter ,when put on the diagnostics machine fault came up as secondary air injection system so the garage renewed the meter and pipes but the fault has reoccured 1 week later i relly need some help as i feel the garage is just guessing at the fault and the costs are starting to build up ,i even bought the car from the repairing garage and they wont pay for any of the parts so i really dont want to take it back .the esr light is the circle with a triangle in the middle i thankyou in advance and appreciate your time dave
