Our Winnebago View Profile was in storage for around 3 years and now the check engine light is coming on. We took it in and the mechanic checked the codes and said it was a DEF issue. He just cleared the codes and the check engine light didn't come back on. We picked it up and drove it home and the check engine light never came on but this morning drove it and the check engine light is on again. I saw others in this group talking about this being an ongoing issue with Mercedes. Can anyone shed any light on this? We are sick of putting money into this expensive motorhome. Seems like it has had one problem after another.
