There were 3 fault codes logged when the engine management light came on: diesel temperature sensor, air mass sensor incongruence & DPF needing clean or renew. The symptoms were loss of power (limp home) but for some reason would eventually rectify itself after 50 miles or so. The dealer says it needs 5 injectors and a new inlet manifold, needless to say I have my doubts! I cleaned the EGR valve yesterday and did a forced regen, reset the diesel temp light and gave it a blast, it seemed more responsive but that might just be psycological.
According to a good diagnostic guy I know, the diesel temp sensor should see 5 volts from the ECU, that in turn returns a voltage to the ECU which then feeds the other engine sensors so I feel that I have to check the DTS first. Anyway, at least I have now found out what Sundays are for......solving Alfa problems!
Any help and advice would be greatly received.
