Official replacement interval for spark plugs on an 07 335i?
I have searched and found two answers, 90-100k and 45k.
I ask because my maintenance warning came on stating that replacement was needed in 3k miles, I have about 42k miles on the car. I scheduled an appt at the dealer and the SA came back saying that his tech said the message was in error and the plugs need replacement at 90k. They reset the light and sent me on my way.
If someone can provide me a document/TSB that I can bring to the dealer stating replacement should be at 45k, it would be greatly appreciated!
