Ford Tourneo 2014

We were approached by a local coach company and asked to investigate an engine management fault with their 2014 2.2 diesel Tourneo    minibus. After driving the vehicle approx 5 miles the engine malfunction lamp would illuminate and default function deployed.  The companies own mechanics had already fitted a new maf (mass air flow) sensor after retrieving an error code associated with that component (a mistake we see quite often)                                                                                                     …

BMW 530 non start fault

A BMW 530 arrived at our workshop on the back of a recovery vehicle recently and we were asked to investigate a non-start fault. The engine would crank but refused to start.

We began by connecting the Autologic Assist in order to communicate with the various modules associated with the media system, though we could communicate with all the modules numerous error codes were present in various modules. The next step was to carry out a fault clear broadcast which clears all the error codes in one operation. Once complete we attempted to switch on the MMI and as expected the system still displayed the fault. We then carried out a loop break diagnostic check, this …
