Customer Question

I'm having an issue with my 525i cranking but not starting. It has 45 psi on the fuel rails and spark on every cylinder. I just got through reading some blogs on the VANOS could it be related?
JA: Thanks. Can you give me any more details about your issue?
Customer: Well if you disconnect the vanos the cars cranking is very labored and when you re-connect the plug it remains the same? Will disconnecting the battery for more than an hour reset the ecu?
JA: OK got it. Last thing — BMW Mechanics generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
