has anyone ever had a problem with the ecu unit on there car,ive got a signum 19cdti 150 and its been in and out of the dealers trying to solve the problem,spanner through car light keeps coming on and every now and then its got a lack of power and a rough idle its had a new egr valve on but hasnt solved the problem.
its now getting a new ecu fitted so hopefully this will cure it,
anybody had this changed on there car ?
