Mini Cooper S, Supercharger Service and common failures

We are running into more and more Mini Cooper S supercharger failures. The supercharger on a Mini Cooper S is belt driven and drives the water pump off the rear of the supercharger. Mini Cooper has no service interval for the replacement of the supercharger oil. We have had many Mini Cooper superchargers fail due to supercharger oil break down or supercharger rear housing leakage. To completely service the supercharger on a Mini Cooper S the water pump must be removed, The supercharger has both a front and rear oil reservoir. The water pump block access to the rear fluid reservoir fill/check hole. To remove the water pump the whole front of the vehicle has to be removed (see picture below). So this IS NOT a do-it-your self type job. We are seeing super chargers failing as early as 60,000 miles if they have not been serviced. Unfortunately the only symptom that the customer experiences is a slight overheating problem under excessive load. This is due to the water pump not spinning fast enough because the gears in the rear of the supercharger have already failed (see pictures below). The gears in the rear of the supercharger can only be service with a new supercharger.
