Excellent question! Denial? Arrogance? Hubris? Parsimony?Wow! I am a Ford Motor Engineer and if we would have a fuel line issue like that on our cars or trucks, there would probably have been a national recall to repair them. Why didn't BMW offer free repairs?
BMW did actually issue a service bulletin that called for inspection of the fuel line clamps but did not authorize replacement and more importantly, did not address the quick disconnect issue at all. When I brought my '03 in to the dealer for the inspection, I directed them to replace all of the OEM clamps with FI clamps. Though I had to pay for the parts, I did not have to pay for the installation labor.
BMW was lucky with this problem - I do not believe that anyone was injured or killed as a direct result of the fuel line issues. So not only were there no lawsuits, BMW also avoided what may have been a substantial cost of repair. This was likely the goal and no doubt made the BMW accountants happy.
What is unfortunate is that this attitude appears to have become the standard BMW modus operandi. For example, BMW bikes have experienced substantially higher FD bearing and input shaft/clutch hub failures than would be expected. Yet the company has not been sympathetic to warranty repairs for what appears to be a combination of design and manufacturing problems.
In my opinion, this attitude is very shortsighted and I am sure that it will cost BMW much more in the long run than they will save on repairs. There are many postive aspects of BMW products and when they work well both their bikes and cars are a joy to operate. Unfortunately, the reluctance of the factory to stand firmly behind their products translates - at least for me - to an even greater reluctance to again purchase anything made by BMW.
