Last week I had my 2008 LL Bean at the dealer where they replaced the ECM.
Yesterday I was driving and got the sense that the speedometer was reading below what I expected. When I compared to my GPS at various speeds, it's about 5-8 mph low. Most speedo errors in my experience read optimistically.
I then noticed that when I turn the car on, the speedo pointer rests below zero. When I started it, I expected it to come up to zero, but it stays in that position. When I begin to drive, it seems to respond quickly and moves through the zero mark at about 5 mph according to my GPS.
Can someone tell me what I am supposed to be seeing as I go through the steps I described above?
It's really bugging me. I plan to call the dealer later today and on the basis that I spent almost $800 on the ECM they'll probably entertain me, but I have little faith in their ability to really know these things. My experience with the dealer's diagnostic skills leaves me doubtful.
Thanks in advance for your reply
