Hi my C5 Allroad has just come back from being serviced and a number Diagnostic errors have come back, just wondering whether anybody of you have come across them before and if there is a remedy?
17978 engine control module disabled.
01318 injection pump control unit j399 not communicating.
18043 Data bus drive train missing message from a/c control module.
17125 torque converter clutch.
18265 load signal error message from ecm.
01400 level control-value below.
01316 break control module.

not sure whether some of these are related? I’ve already spent £2k so from your experiences is it worth carrying on? Body work and general conditioning is excellent and has just sailed through its mot.
