Hello together, I know that there was this topic before. But I could not find any answers to it. To my problem: I have been driving a Trafic II for years from 2008. I bought the Fzg. used. Before it was commercially operated with trailers. Therefore it is equipped with an electronic tachograph (1381). I use the Fzg. only privately, therefore the device has no meaning for me. It is also not entered in the papers anywhere. hteil: Time and total kilometer stand are only displayed in this device, not in AI. A few months ago the device stopped its service. Now the next TÜV appointment was, actually no defects however wg. Missing kilometer stand (graving defect) no TÜV. Now I am looking for someone who can reprogram the electronics to operation without tachograph. Renault bricks up pretty much. All dealers say they can’t. Renault Germany takes my A Regional tachograph service refers me to Renault, Renault refers me to the tachograph service. Tacho service in Holland has tried in vain for 4 hours and now refers me back to Renault… Once again to the exact problem: tachographs have now been expanded. Tacho and day-kilometres work. Total kilometers are not displayed in AI. With workshop software the current km stand from the electronics can be read out, So it’s just a specialist in both AI and electronics that has to put a catch on “Operation without tachograph”. I know now that this doesn’t take half an hour at Mercedes. There has to be someone who can do that at Renault. I’m grateful for all the tips. Peter
