My car's been stuck in storage for the last 9 months has only driven about 30 miles in the last week.
My garage says the emissions are too high, the CO2 level is 0.83% when it should below 0.3% and also the HC level is 218ppm when it should be below 200ppm.
This happens on both the fast and natural idle tests.
They say my catalytic converter is probably blame although the emissions were fine just before it went into storage.
Does anyone know if it being in storage would have anything to do with the emissions? do you reckon if i took the car on a long drive, it would be ok??
or does anyone know of anything i could do to fix it without replacing the cat? I've been quoted around £400, although i'm pretty sure i could get it cheaper.
Thanks if you can help
