i have a 55 reg doblo 1.9 jtd, which has had the mil light coming on intermittently. i have had it into a fiat garage, who have replaced the map sensor which worked until i got car back and drove it away.. having returned it they now say there is a fault code, p0401 but they have no idea what it is. has any one else had this code, or know what it refers too, i was thinking egr valve but this was replaces approx 18 months ago...
 
Hi mate,

P040* is EGR related I do believe (just shocked and saddened myself that i remember fault codes off by heart).

As it was replaced, I would start by checking the wiring to it. Its quite easy to damage the wiring or knock the plug when putting the engine cover back on. Are you getting any other symptoms?
