Mark

Mark was going to replace the transmission fluid and fix a torn rubber cover of the drive mode selection stick. Having opened up the car he realized that he got a wrong filter part for transmission. This was not his fault (apparently yourmechanic did not ). So Mark had to come again and do a lot of extra work (for no additional pay). He also tried to glue the torn rubber. Somehow he put far too much glue and glued together parts which prevented the drive selection stick from going into some modes. He also somehow managed to leave unremovable superglue on the steering wheel. When I contacted him he came to separate the accidentally glued parts. He managed to fix the sticking but as a result also the part which was supposed to be glued disconnected again. He then told me he is going to look into replacing the part. He did not get back for two weeks. After I reminded him he said he could not figure out the part and said he'll get back to me. But after another week I just went to the authorized dealer and got it fixed. I also checked online and the part was very easy to find on audiparts.com

This was my first time using Your Mechanic so, I was quite a bit skeptical. It took about an hour for Stefan to check out my car so, again, I am thinking he's probably finding a million things wrong and it's going to cost a fortune. Well, to my delight, he only found a couple of things - did not pressure me to let them do the work and even added I could wait a month or so to have the work done. After he left, I went online and my quote was waiting - I was astounded at the fair price I was quoted. I will definitely do business with them again and have ALREADY recommended to 2 friends of mine. VERY impressed!!

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.
