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

I thought David was great. He was very courteous and professional. He did a pre-used car inspection for me on May 7, 2016. However, I filled the vehicle with gas yesterday and it has serious gas leak. So this is an aspect of his inspection that he missed. Again, I thought he was very professional and would recommend him. But any such inspections in the future should include the gas tank.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
