I changed my OVP on my 1986 300E about 3 years ago. This past weekend the OVP failed. Now I have to buy another one. What is the life span of these relays? I was expecting this new "KAE" made OVP to last me at least 10yrs. Now I'm hesitant to purchase this aftermarket brand.

What have been some of your experiences with this part?
