I think it is Poorly, as the engine management light has re-appeared on the dash again, as when i first bought the car, when i took it back and had them fix it, they said they had to replace the lamba sensor, due to an O2 sensor fault, and will be warranted for 12mths, now informed them i need to bring the car back to them, but have been told it will cost £40 diagnostic's to check it is the same fault, but concerned if the car sales has sold me it with faults, (as even got the car from an auction), as when i had the scorpion exhaust fitted, i was informed i had a wheel bearing going on the car, which i did not know, but on my first purchase of the car, they said they had replaced the brake disc's and pads, And a new heat shield put on the car to pass the MOT and service before handing me the car. The bluefin superchip diagnostics did gather 001 DTC errors 1218 and cleared them but could not clear all the DTC errors, so will it be the lamba or will it be the ECU unit is faulty, problems i seem to need to find out, and am i being duped by the garage with a quick repair
