I have owned a 740il since 34k miles (now 95k) bought certified and cared for by Rallye Motors in NY through expiration. oil always changed and no major problems.
Now I have a sweet, almost maple syrupy smell form vents...believe a heater core problem? Any thoughts about cost to repair ? 9what does the book say about labor hours?
Also, any idea of value? I know what KBB says, but....
Otherwise mechanically great and visually perfect.
Thanks for any info.
