Sounds rough. Look on the bright side - you now have enough spare parts to last for many years to come. The dealer is not taking responsibility because you're not buying the parts there. In fact you have no one taking responsibility. If I were in your shoes I would learn how to read the fault codes (by doing a search above) and then read and clear them every day until a clear trend developed. That sort of behavior should put off some fault codes. BTW, that sounds like a bad policy by Beckman - I would hope they would reconsider, might be worth a try.
