Car - Audi TT Sports Jason has worked multiple times with my car. This appointment was wrt to some squeaking noises from the power steering. He inspected the car, and quickly found the sensor to be defective. We went ahead to order the part, and Jason would fix it in the next appointment. Jason has deep mechanical knowledge of car(mine is European). He diagnoses, the problems very accurately, and explains very well. Jason also goes the extra mile, helping to buy the correct item. All in all, i would recommend him very highly, and would reach out to him for further repairs.

I was a little sceptical of how this might work but there was no need for any concern. TJ kept me informed prior to the appointment and provided clear summary of the work and approach he was to carry out. Not only did he fix the fault, he also provided a inspection making recommendations of what work might need to be carried out. The cost was extremely reasonable as well, less than all other quotes I received from traditional garages backed up with a 12 month warranty. An appointment was arranged for the following day whereas other garages I had to wait at least a week. Plus there was the convenience of being at home. Excellent experience and will not hesitate to use YM again. Ideal for the busy family. TJ is passionate about what he does and provides an excellent customer service. Thanks!

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.
