At about 180 hrs. the tractor started running a regen cycle every four hours. I checked with a dealership and was told that was normal. As tractors get older, they get dirtier. At 190 hrs. it started flashing the two warning lights in the dash that indicate an operator safety issue. I couldn't find the issue and the code it was displaying was not in the dealer's repair manual. They called Yanmar and were told that it indicated a bad water separator. I am not sure how that can be a safety issue. The part was backordered. The dealer cleared the code and the lights were out. I was told to use it until the part came in. I ran it for about 20 minutes and it started a regen cycle and the dash lit back up. It started running a regen cycle about every 40 minutes and. . . the oil pan started filling with diesel. It is back at the dealership. I am not complaining about the dealership. I have talked to their mechanics and the service manager is working on the problem. I am looking for ideas that I might bounce off the dealership mechanics. At this point I think the code and the lights are meaningless and may indicate a computer problem. The engine is running fine and every diesel that I have been around with significant water in the fuel ran poorly if at all. They seem to have nothing to do with diesel getting to the pan. Emails from Yanmar to the dealership don't seem to grasp the issue. They focus strictly on the code on the dash.
