Not sure if i have all the info but as i know it this is the prblem. customer said he had poor starting and after ignoring that for several days the car lost power(limp home i guess).He then changed the battery.Now the car starts ok,idle a bit erratic for a few seconds but drives well the problem is it has now lost cdl,indicators,fuel guage and hazzards.Dashboard says visit workshop display fault.Data link only has one message P202D can message from instrument cluster.Have checked fuses.Any help would be great,thanks.
