What does the O2 sensor do on a Volkswagen Golf?
Your Golf’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly.
Why are my LED lights not working on my VW Golf?
You can also go into the Golf's menu system and change the behaviour of many things including lights. If it worked with the old Globes and then you installed LEDS and it no longer works then another option is that the LEDs have damaged the Golf's electronics – or caused the CANBus system to go into some error mode which needs clearing.
Why does my check engine light come on in my golf?
Oxygen sensors can change the way that your Golf’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.

What is the oxygen sensor after the catalytic converter?
Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios. By using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it.
What is the first O2 sensor?
Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor.
What happens when an O2 sensor goes bad?
