04 1.4.16v anti pollution fault, catalytic convert - jules46
Please can you help me i have a 04 1.4 16v 307. It has done 40.000 miles. Recently the engine diagnostics warning lights comes on and the multi funtion display shows anti-pollution fault and catalytic convertor fault. Does this mean i need a new cat because i have read that a faulty lambda sensor can effect the cat and the running of the car. Pease can you advise me what to do.
thanks

Dont panic just yet.

Suggest you get a gas test of the emissions for some figures to work with.

presumably some body (garage) has read the codes and told you this info? Did they detail what was needed? or just guess at whats needed? if so, get another opinion, but fairly quickly.

Doing nothing but still driving with it like it is will not help it!
