A former neighbour and still friend owns a Bessacar motorhome, not sure which model.Anyway, the vehicle had a intermittent fault on the nearside indicators. Basically when indicating left, the rear and mirror indicator failed to work, but the front indicator was fine. Took van to a garage, who then recommended an auto electrical technician. They said that unless fault actually showing at the time , was difficult to diagnose, but probably body control module had gone, suggested take it to the main fiat dealership. This was duly done, 2 hours of diagnostics showed nothing, but mechanic's again pointed to the body control module, but could not be sure, and confirmed even if a new one purchased and fitted, problem could still exist. New module ordered from Italy, cost £ 1000.00, 5 days to arrive, was programmed to said vehicle, didn't work. What next. Dealership suggested a full wiring check, a couple of hours later, front seat removed, part of the wiring for the indicators had chaffed and thus the cause of the problem. So now neighbour has 2 body module units, is £ 1450.00 less well off, and apparently once unit is programmed to vehicle, that's it, cannot be used on another vehicle. Years ago, a continuity check of the wiring would have been standard practice, or if module was say inexpensive, then a quick swop would confirm either way, but £ 1000.00 and no guarantee, what would you guys have done.
