GTI 337/20th Anniversary :: CEL Came On - Bad O2 Sensor?
May 21, 2013
so my check engine light came on recently and i took my car to a local shop to get it checked out and they told me one of my o2 sensors might be bad and that i should replace it. but because the catalytic converter that i have installed is an aftermarket one(installed before i bought the car used), they told me they were unable to remove the sensor attached because it was welded(?) on or something to that effect and they didnt have the tools to fix it.
so i did some research and found a better shop that deals with catalytic converters and exhaust systems and im thinking of taking my car there to see what they can do BUT, i was just researching online and ive found other posts saying that it may not even be a bad o2 sensor, it could be a different problem but the its just the bad o2 sensor code that comes up and now i dont know what to do.
just wanted to see what everyones opinion is on this subject or if they have gone through this before!

Got a code for knock sensor bank one however this is the wiring going to it. Could it be throwing the code simply because the wire is cut or do i need a new sensor maybe too?

So the motor has a new oil pump and pickup and was all cleaned out. Sludge is not the issue here. I'm running the royal purple filter ( the equivalent of mann 950/4) and royal purple 5w30. My heart dropped after the light came on on the first drive. I pulled out over and checked the oil and for leaks and... full with no leak. So I checked the temp and proceeded to drive home. I don't have an oil pressure gauge but I'm getting the bottom of the fill cap with oil so I know it's making it all the way to the top of the motor, and the motor is not loud or sounding starved.
Basically, I wanted a second opinion that it is most likely oil pressure sensor malfunction. Garrett 60 trim, feed and return lines are brand new and sufficient diameter.

I have an 04 GLI and keeps throwing a code for the 02 sensor, and after putting the car on the lift, and disconnecting the 02 sensor harness, a fine oil leaks out at the end of the connector and smells and looks like power steering fluid.

I have an '05 GLI @ 45,000/mi. The sensor light came on for my brake pads about a week ago. So obviously I need new brake pads (front & rear? not sure...I know the sensor is only for the front). But I was also wondering if I need to replace the rotors.
I understand there is a measurement for the OEM rotors to tell when they need to be replaced. There is a little lip on the them, more so on the front than back. And they feel slightly grooved.

So I have a bad map sensor and lately my turbos been going in and out of limp mode. I recently just replaced with a new n75 valve and it solved the problem for about a week and now it's acting up again. Its not a constant problem it occurs usually every 20 starts. Could the map sensor be the reason why my car is going into limp mode?

The CEL just came on in my 20th AE Gti. The code indicates a Camshaft Position Sensor issue. Don't know where this sensor lives under the hood of the GTI? Is an easy enough fix for a beginner to attempt? (have hand tools, former bike mechanic, but no shop just a parking lot in the Texas sun!)

My Jetta has been throwing this code on and off for over a year now. It used to only come on when it was really cold with wet roads. Now the code will randomly come on in any weather. I usually just clear it but it's coming on to often now. I don't notice any performance issues or gas mileage problems.
Scan shows : Trouble Code - P0420 Catalyst System Efficiency Below Threshold (Bank 1)
I've been reading and apparently 1.8t engines only have One bank? I'm assuming this the the front 02 sensor throwing this but not sure?
I have an aftermarket exhaust/high flow cat. Apparently this can be caused by a high flow after market catalytic converter and one solution is to use a test pipe or spacer to move the rear O2 sensor further from the exhaust gas flow. But I'm not sure this is the issue since I think it's my front sensor throwing the code? That's not by the Cat is it? I just don't want to have the sensor replaced to have the code still come up.

Just got hit with the P0130 code when my CEL came on for the pre-cat o2 sensor. On ecs there are front and rear sensors. I'm assuming front would correspond to the pre-cat that is throwing the code?

(6 speed)... I have faulty reverse lights, my speed sensor is working so I am sure it isn't the fuse, I am guessing this means the switch/sensor is broken. Where it is located, and what the correct part number is?

When I bought my 2003 20th it was completely stock, except for a pos blow off valve had been installed, and get this, the diverter valve was left on, and just capped off. I installed a no name CAI, and the check engine light came on, i had it turned off and when i start the car, or rev the engine high at all, triggers again.

I have a light flickering on and off that claims the door is open, after a few months and a lot of testing I have come to the assumption that the sensor in my trunk hatch is sending a relay to the computer as if the door is open.... I can't find a latch sensor or relay for this thing, just the striker plate and the wiring that unlocks the switch as well as the wiring for the rear wiper blade....

I put in a new sensor to stop the problem but now I have the code 00778 which is steering angle sensor and then says 005 no or incorrect basic settings/adaption. I went through the Ross-Tech site to reset the code in group 60 and activate the basic settings, but I am then told that group 060 is not available. I have tried to set the steering wheel angle straight but the angle still says its at 349.47*. My car is a 2004 Jetta GLI 1.8T.

I want a 20th AE & have seen pics that say ESP on a button next to the hazard & others say ASR. I know that their was one option for the car: ESP. So what's ASR? Is one better than the other? Is it the same? I've heard that the ESP sucks for autocross. Is this true?
