I have a two-year old Vauxhall Astra 1.6 Estate with factory-fitted LPG conversion. Since mid-October the "Exhaust Emissions" light (engine symbol) has regularly been illuminated, sometimes flashing when I accelerate. The car is still under manufacturer's warrenty, so at no charge to me the "DIS Pack" (Direct Injection System?) has been replaced in early November and again in mid December, but in each case the light illuminates again within a week or so. On the third occasion the garage diagnosed that a Crankshaft sensor needed to be replaced, which had to be ordered. This arrived last week, was fitted on Thursday, but the light was on again by Saturday.
Have any of you good people suggestions? Thanks.
