this could be the FAP filter in the exhaust, think there was a thred about this a while ago, how many miles has the 307 done? it could be time for a costly new filter?

It could be an EGR valve.

Hi all
thanks for the responce. what is a 'FAP filter in the exhaust' the car has 78,000miles and i have replaced the cat filter in the exhaust about 4,000 miles ago. this was quite expensive. are we talking about the same thing.

what is a 'EGR valve'?

hope you can help me track down this fault.
many thanks
happy xmas if you celebrate.

Exhaust Gas Recirculation valve, it puts watste gases from the exhaust back into the engine to reduce emissions. they go on HDIs
