I got a CEL w/ code P0420, (Cat below threshold). Im running a 3" 42dd downpipe with hfc. Im assuming my cat took a dump, and my question is, if i get REVO Stage 2 Will my CEL be cleared, or would it come back?
View 8 RepliesCar is throwing Converter below threshold code. I figured i would put in MagnaFlow High-Flow cat from my work but didnt know if that would work. The position of the stock 02 sensor is what baffles me.
It seems to me the factory design has the 02 sensor in between 2 chambers. Could I just install this Magnaflow cat and put the 02 sensor after the cat? Can get rid of this code after installing high-flow cat?
Last night driving home my cel came on and I didn't hear anything off so I finished my drive home and scanned my car. The only code that came up was the p0171 code. I know it's a at system running lean code and I have looked and researched the issue. Some of the threads I've read have had bad endings, or this has caused their car to throw more codes the longer they drove it. I know about the maf sensor, checking for leaks, possible 02 sensor, things of that sort. My car is an 05 mk4 gli, apr stage 1, 007 dv, brand new n75, and brand new plugs/wires. Oil was also changed about 1000 miles ago. I'm trying to do this all myself if possible.
View 16 RepliesI have a 2004.5 Gli that I'm getting really excited to fix. First question as a Noob how many miles can I get out of the engine with regular up keep. It has 140k? I just had the timing belt and water pump done and it feels great but i dont want to get into a huge money sandpit.
There is water getting in when it rains which has caused the liner to lift off of the A pillar and the B pillar gets moist as well. No damage to the head liner at all just the pillars and the door liner has gotten damaged and lifted. I've already checked the the sun room drains/drain nipples they work great.
I have to get the front end fixed- New valance and paint. I'm sure this will have to wait till next summer so i can save the funds to have a good paint job/blend of the hood and fenders. Plus my driver side door needs a touch up after being keyed.
After searching the forum all day yesterday i found the color code for the rc's and was going to get them powder coated due to curb rash and really bad chips. But is the oem brilliant silver color the best for the Grey metallic color GLi?
Obviously I am wanting to first work on the exterior aesthetics of the car first. Engine performance is fine, I am not a heavy footed driver on the streets and on the hwy it does fine at 90. But I do see a chip and FMIC in the next year being a possibility.
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?
View 8 RepliesI was driving at about 60mph in 4th gear and knocked it into 2nd and the rpm's hit the max and the car shut off and I have not been able to get it started. I have compression, fuel, and spark . I've checked oil and don't have any coolant in and nor did I have any oil in my coolant. When I try to start it it try's to start but won't turn over so .
View 12 RepliesDriving home from work, I was about 5 minutes from home, got to a light only to not be able to go into 1st. I popped it into 2nd and drove home like that pretty much. Car will let me get into reverse and all other gears.
I can put the shifter towards first but it doesn't fully go in and when I gave it gas it would let me start to creep and then grind a little and pop out.
Heres a pic for your click .....
I was searching but I can't find any DYI's on turning your Daytime Running Lights off on our cars. I don't feel like buying a euro switch right now. How to do this or has done this to their vw's?
View 24 RepliesI was following the directions on the APR site to remove the ECU and it seems to not make sense. Saying the ECU is on the passenger side underneath the molding....
is the ECU in the center?
I've had the leak for a long time now possibly from when I've gotten it... anyway when I first bought it I drove it a lot, like 8k miles in 6 months. During that time I went through a qt of oil about every week and a half. Now the last 3 months I've been barely driving it due to life changes so I'm barely putting oil in I'll go weeks sometimes of checking the level and it'll be fine. This leak has to relate with how often its driven and maybe hot?
I've had the car up multiple times to try and find the spot all I know is it's behind the engine below the valve cover gasket and above or near the turbo area(I've only owned my first VW this 20th for less then a yr so I'm still learning)
I get up to go to work today and the car runs fine, a few hours later i get back in, try to put it in reverse, and nothing.. it wont let me shift in after i push it down. So i push it back in neutral and drive away.. every gear works fine, when i got home i took off the boot, tried to see if anything was loose, shake it a few times and out of nowhere first and second give. They were working perfectly 5 min before, and now they just feel really loose, but every other gear works fine, so now I have no reverse, 1st or 2nd. Did I just knock something out of alignment or is the problem a lot worse.
View 3 RepliesI recently took out my headliner And my passenger's side seat. When I put everything back together, I turned the car on and the light came on. What can be the issue?
View 10 RepliesAfter I got gas yesterday I drove about 10miles and the CEL light came on. The gas cap seemed a little loose so I am assuming it is that until I get it scanned soon. I was just wondering how long is stayed on if it wasn't cleared, I know some cars take a few days.
Does euroswitch installed have a problem with the audible headlights-are-still-on tone? If I leave my lights on, and exit the car no sound will sound. If I open it back up, then it will make a sound. Pretty useless.
Also, still looking on the best length for the Thule wind fairing for stock votex racks?
So I just changed the valve cover fast but I am still getting oil onto the hood of my car. It did this before I changed the gasket as well. Is my valve cover bent maybe?
View 7 RepliesOk first lemme start I have a 20th with 76,000 miles chipped. I was driving down my street and the car julted a little, didn't think it was much, kept driving the check engine light turned on and the engine sounded like it was hesitating and I lost alot of power. Also it sounds like a Subaru. I haven't yet changed my coils so I'm thinking that's what it is.
View 3 Repliesso 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!
I am trying to put a exhaust cut out on my car, I am trying to put it right before the cat. Looking for pics?
View 15 RepliesI have a problem with my 20th anniversary gti. My 1st and 2nd gear won't work. Every other gear works fine, the gears never grind before or any unusually noise. I was pulling off my driveway and they just stop working. Even when the car it's on I can move my shifter to 1st and 2nd without the clutch and nothing happens.

View 10 RepliesI started up my car after work and and it had a super low idle it almost seemed like it wanted to shut off. I brought the rpms up to 2k for only for a few sec. Let off it was fine? It was cold out. But its never done that b4.
It almost felt like it was bogging out. I have brand new air filter. And spark plugs.
