I have had my motorhome in my local garage and the main fiat commercial dealer for a diagnostic check and repair but this only lasted for approximately 100 miles. They would not take a further look at the problem. My local garage is very helpful but say a will need a wiring diagram and the help of their auto electrician. The fault comes up as "Lamba Sensor" but this has been changed several times. The main dealer repair was repairing a wire in ECM harness. The The codes are "P2248 stored" and "P2248 Sporadic". Can anyone tell me where I might get a wiring diagram as this problem has dragged on for a year. Thanks Brinton.
