I recently went to Autozone to purchase an oxygen sensor for my 2000 Jetta, but the Customer Rep. asked me if it's the 1st(top) or 2nd(bottom) section that needs to be replaced. The only way I can find out is by taking it to Pep Boys but they're a rip-off. Does anyone know which section it is?
The Engine Light shows up, several car shops and friends have told me it's the Oxygen Sensor.

Without knowing the code it set and which sensor it refers to it still thrown darts at it.Must likely it the pre cat or sensor before the cat but every once in a while the post or after cat sensor goes.Also check the wiring to make sure that it not just a burnt or broken wire causing it.It may seem a rip off to you but you have to check a sh*t load of things before you put an o2 sensor in a car.It could be any # of things Leaky injector bad wiring bad map sensor bad computer. Tech have to get paid to do these checks. If pep boys is going to rip you off go somewhere else.Find a good shop not all of us want to rip you off.

the code will read bank1,sensor1, or bank 1, sensor2. that is what you need to know. not top or bottom. there is no such thing. why dont you take it to a REAL auto repair shop, and just fix it. be done with it. as for the chickie-roo that claims the cat converter will fail soon after the oxygen sensor fail, you couldn't be any more off base with that statement if you tried. dont 'help' if you dont know any more than that. a bad oxygen sensor will not cause a failed cat converter,or cause a trouble code for the cat converter.ive been a journeyman auto tech since 1978,and i am sure of what i'm saying.

As other have suggested, you can go to Autozone or Advanced Auto Parts and they will scan for free. The scanner often will have detailed text to advise which oxygen sensor (if it is this) has a problem. If it only reports the code, this website will give you the verbiage. It even has Manufacturer specific codes. I just checked, and they have one for Volkswagon.

You can by a diagnostic tester at any auto store and find out why your engine light is coming on. Sometimes it is as simple as a small hole in a vacuum hose. I think it would be worth the expense for a diagnostic tester to find the problem. Of course, if you know the codes, you can turn on your vehicle, then switch to accessories only and it will blink out the code.

The car has 2 Oxygen sensors, one before the Cat and one after....that's what he is asking you...which one do you need?? If you don't know which one you need, then you shouldn't be fixing your car.....It's like this guy I saw the other day dropping bullets down his rifle barrell....I asked what he was doing and he replied, "Loading my gun to go hunting, why?"

If you have an Advance Auto Parts near you, they will check the codes on your car for free, and might be able to tell you what has caused the light to come on.

Be carefull too -- Once your oxygen sensor goes, your catalytic converter will be following it (if it hasn't already). It was about 2 weeks between on my 96' Grand Am.

If Autozone hooks it up to the diagnostic tool they should be able to tell you by the code that pops up.
