Engine light coming on .Just wondered why this issue not dealt with amazon assuming a sensor has been damaged or dislodged while exhaust fitted or leak in exhaust mainly manifold. Any reason this not been found .or am I way off mark .

Thank you for your post Greenman.
Once the standard headers and exhaust had been replaced by the Kooks long tube headers and full stainless Borla Atak exhaust system the ECU very occasionally ( the EML light has come on once in 18 months!) thinks there is an exhaust emission malfunction which of course there is not. There have been no MOT emission issues as can bear seen from the MOT history.
It can apparently can be remedied by fitting a spacer washer under the front sensor which I have not done as I considered it to be completely trivial and also it is very difficult to access the underside without a full 4 poster ramp which I do not possess.
Trust this clarifies for you
