Okay, I dropped my car off for the second maintenance today (26K miles)and asked what he knew about CBU and how many diesels he sees. He said he sees about 2 or 3 diesels a day which I find hard to believe because I haven't seen any others in town in 2 years. Anyway, he said he has only see two with CBU issues and those were around 60K Miles. One was covered under a BMW extended warranty, the other OoP expense to the owner of about 5,500. I asked if BMW was stepping up to the plate to fix these issues and he then went on to say it is not a BMW or engine issue and that its caused by the quality of fuel. I told him I have owned five different diesels over 20 years and have never had CBU issues in the past and asked how he could say it was the fuel only. I hate it when people think you're stupid. He was not to happy after that and his tone changed and seem to want to get rid of me quickly. I would be interested to see what others are hearing from their dealers.
