Readings taken downstream (exhaust) with the O2 sensor are telling your computer that the catalytic converter is not doing its job well enough (it is reading too high an exhaust content of carbon monoxide or hydrocarbons) the solution is to replace the catalytic converter assuming the engine and its other management systems are performing healthy ....good luck

Engine symbol on dashboard on - what does this mean ?


You have a check engine light, a code for something. VW's throw code's easy because they have sensors everywhere. It can be something as stupid as not having your gas cap on tight enough, and then it senses a vacuum leak.

Either way, you have to get a code reader, or bring it in to a local parts store, Advance and Autozone, etc. will scan for free. Otherwise, do yourself a favor and buy yourself a cheap code reader off ebay.

I have a 2002 vw passat and my abs light came on and shut off is this goin to b a problem my car has 97,000 mile


The ABS system means the Anti-lock Brake System. If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS Electronic Control Unit (ECU) memory to pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.

AIR BAG FAULT WARNING LIGHT KEEPS COMEING WHEN CAR IS STARTED


I had the same problem. My 2008 Passat had to get a faulty rotator that controls the electrical part of the dashboard on the car.First the Air Fault light came on then my whole dashboard went out the next day. I had no horn, no radio, no lights on at all on the dashboard. It was that rotator part that controls the electrics. I was told they are faulty after a few months, they ordered a new one, installed and my car is good as new.
