how can i fix my peugeot 307 hdi ?

Don't bother taking it for a drive it wont clear the fault. It is an air flow sensor in the tube before the air filter. Average price £100 for a flimsy sensor. absolute rip off from Peugeot.

If you get it started try giving it a good long run in low gears at high revs to get the exhaust really hot and give the particulate filter in the exhaust a clean out,if no better then it will need to go onto the correct computer/code reader to sort your problem out.Could be expensive.
