was the second repair I did on my wife’s 2012 50i. 3/10 difficulty all access from below. To it properly you need a scanner such as a Foxwell 510 or 710 in order to calibrate after.

You also need 300 pounds of weight. I happened to have a set of mounted tires which weighs almost exactly 300 pounds.
