I got a diagnosis from Jay on my BMW's Service Engine Soon light and he traced the problem to the Secondary Air Injection Valve. Jay explained to me and I learned the functionalities of the Secondary Air Injection System. He then replaced the offending part when it became available in a few days. I was also pleased that I received credit for the cost of diagnosis toward the cost of replacing the valve (parts and labor). YourMechanic is the way to go!

Pete was great! I got an oil change and tire rotation on my BMW 328i. Pete arrived a few minutes early, worked fast, and was friendly. He even helped me out by providing me the service engine warning light codes since he needed to clear my oil change light anyways. I'd highly recommend Pete!

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.
