We have a 318 1.9 (1999 V) with an engine light problem,scanned and replaced one oxy sensor reset and all was ok until the 'cycle' of using the car from cold to hot 3 times was completed and then light came on again. The scan indicated oxy sensor again so we replaced the other and the same thing happened. We have also replaced the air mass meter and the purge canister recently on the car. The latest scan showed an air leak,the only place we thought this could be from was the manifold so we have just replaced all the gaskets and seals...couple of days later the light is back on!...can anyone help??
