He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you

All about Serpentine/Drive Belt Replacement

The serpentine/drive belt or v-belt is a rubber belt that connects the alternator, power steering, and AC to the part of the engine (crankshaft) which transfers the power from the engine to those components. Without this belt, the battery will not get charged and none of the electrical accessory components in the car will work. The serpentine belt and v-belt are also known as "drive belts." Because of the high amount of heat in the engine, the belt can develop cracks over time and eventually break. If the belt breaks, the steering wheel will be difficult to turn and driving will be hazardous. In some cars, water pumps are driven by the drive belts. If the belt breaks, water and coolant needed to keep the engine cool will not properly flow to the engine. The engine will overheat, potentially causing severe damage.
