HC Emissions 147

Hi Guys

Just had the girl MOT'd and she passed (phew - worst day of the year MOT day) but the emissions reading seems to have shot up over the last 12mth

Fast idle

CO 0% (same as last year)
HC 131 ppm (up from 24 ppm last year)
Lambda 1.01 (same as last year)

She's a 52 plate 147 T Spark Lusso 1.6

Last service at 48,000 miles (two years ago) and on 58,000 now so she's due one. Running her on bog standard Morrisions fuel.

Does anyone have an idea why the big jump and what I could do to try and make sure she passes next time around too.

Thanks in advance

btw I'm a technical idiot so please use language I might understand
