WOW 4 years mate, seems like the x,s are like a proper lady, need constant attention, very sensitive, high matainence, and when there is a problem and ask what's wrong the answer is nothing but you no deep down there is somthing wrong that you will pay for eventually. Ha, don't get me wrong I enjoy spending money on her but there is nothing worse than spending on parts just trying to find the issue. I feel for you mate that would have put me in a "nut house/loony bin/mental instertution," after 4 years.
