Its rather a expensive part when you break it....

if the odometer is broken in a car you cannot sell it in the state of california (I say this because I went threw the same thing when I bought my 300e, odometer was broken, and she couldn't get the car smogged because of it.)


but if it happens again, just push the plunger in a multituted of times in a row, it will set itself to a place where you can drive.
