did the air filter all click back together properly? Air leak?

3ff1 in my book says Mass air flow sensor.

Hi, it was a pain but think it was ok, i'm happy to remove and refit if you think thats a posible cause.

Did you connect the MAF back correctly?

Yes, looks good, it did have another code which said no.2 glow plug but they both cleared for a day, think i'll check air box and plug in again or should the light go out when fault fixed?

Ifthe code has come on straight after taking the intake hoses then start there.

Disconnect everything, give it a good clean, use a small amount of grease/vaseline around the rubber seals and put back together. Always start at the simple + cheap options first!
