Hi

I have engine management light on and car running rough until i drive to end of my short road in the morning and also car just scraped through MOT last week on emissions.The only fault code registered is P0412

So i think the problem could be non working secondary air pump or inoperative secondary air injection valve or a combination of the 2 !!

I have to confess I havent done any investigative work as yet Im just hoping you guys might have some clues !!

is there a fuse for the secondary air pump ?

If I clean the secondary air injection valve is that likely to solve this ?

any help on this is much appreciated
