ha! i am not joking at all just worried and am not a car guy at all! as you refered to the stickies i have not seen them this is my first day ever on this site. I keep up on all my oil changes but just wanted to know the urgency of the wrenches thanks againI have to assume that your ML is a recent purchase? Double blinking wrenches means that it's time to perform the "B" service to your vehicle. It will run you about $400 at a dealership.
FYI - Service intervals for this vehicle run on a (typically) 6-month rotation. "A" service is the smaller of the two, and it usually runs about $250. Then, 6 months later, it's time for "B" service.
Please check the stickies at the top of this post for pertinent information regarding the upkeep of your vehicle. Unless, of course, you are intentionally asking an easily-researched question as an April Fools prank, in which case I applaud your ruse. Well played, sir.
