I am the original owner of 2004 530i BMW and haved followed all maintenence requirements. On 7/7/10, took my car in for routine oil service (54, 777 miles) at Encinitas BMW. Within 2 weeks post service, the engine overheated and check engine light came on. Took it to an independent BMW specialist and they said the radiator was empty. After extensive evaluation, the radiator was fine, it was holding pressure and there was no leakage. So I went back to Encinitas BMW dealership to have the check engine light evaluated and after the diagnostic check, they said I needed a new engine ($13, 500) because they think the engine got too hot. The initial oil service included radiator check and I believe they never filled the radiator fluid which caused the engine to overheat. Therefore I had to buy a new engine for $13, 500 even though my original engine only had 55K miles due to their error.
