Hi All,
Newbie here so go easy please!
2007 1.9 CDTi SRi 150

Had the MOT yesterday - passed with flying colours. Only advisory was a slightly corroded rear disc and engine oil a bit low.

Anyway topped up the oil last night but spilt a bit around the filler, cleaned it up quickly and didn't think it had gone too far. This morning the exhaust emissions light is on (orange engine symbol).

Could this be caused by my "spillage" getting somewhere it shouldn't have or is something likely to be broke?

Car runs fine, no loss of power or any other symptoms, also emissions test on the MOT was fine.

Any help much appreciated.

Thanks & regards,
