Golf IV / Jetta IV :: EPC Light Came On - Codes P0221 And P2637
I bought my son a 2005 GTI MkIV (great dad right). On the drive home it threw a light the code was P4011 secondary air no prob found a hose off and issue solved. The car had 66k so I made him leave it at home until the timing belt was changed (read about alot of failures between 60 and 80k). Everything was great for 2 weeks last Thursday the EPC light came on and he got it home in limp mode. I pulled the following codes P0221 and P2637.
Am I looking for a short? I have read that it has been the following.
Brake light switch
Gas pedal
MAF
Intake manifold...
Toyota - Corolla :: P0171/ P0420 And P0441 OBD Codes - Excessive Oil Burning
I just bought a used Toyota Corolla 2002 CE with 120K miles two months ago. the car seemed fine and drives fine too. After a while I found out that the seller had removed the "check engine" light, so I read the error code by a instrument and I got these errors. 171,420,441. And I noticed that the engine burn a quarter oil every 200 miles on long drives!I checked the VSV valve and connected hoses but no problem there. Since the car has just 120K miles, I'm not sure that the piston rings are worn out! I'm wondering what could cause all of these errors?

I recently had an issue with a coolant leak. the Y shaped coolant line connection went bad located under the power steering reservoir. The car got hot and the coolant light came on i immediately turned the car off and saw coolant leaking out from this.
Now today I start my car it has a rough idle and dies once it dies it doesn't start again and the epic light comes on throwing the codes

Golf IV / Jetta IV :: 1.8t Won't Start / Throwing 2 Codes
Throwing 2 codes -
P0172: too rich
P1176: post cat 02 reached limit
Last time it turned on it had horrible air flow, it felt as though it was choking. definitely not a misfire. occasionally after spirited driving the engine would die after I came to a complete stop then worsened to cutting off when I put the clutch in at high rpms. also have a slight loss of power. I also recently added a 3" tbe and changed coil packs.
Golf IV / Jetta IV :: 2.0 Throwing Multiple Codes
So my car has been dropping multiple codes after I scanned her and found all five: p0303, p1128, p0172, p1300, p0301. She is just a simple five speed AEG and has no mods other than a SRI. I already replaced the MAF but that ended up causing more codes and I have checked the vacuum lines to no avail.
View 2 RepliesGolf IV / Jetta IV :: 1.8t Throwing Codes And Misfire - CEL Came On And Blinks
So recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.
Golf IV / Jetta IV :: CEL 2 Codes P0420 And P2181 Came Up At Same Time
I just picked up a MK4 gls 1.8t jetta for a project car.... I wanted to keep the miles off my MK6 gti.... The jetta has 92k miles and the first thing I had done was the timing belt service done as well as a new alternator clutch pulley and oil change... 1 day after I got the car i was driving to work and the CEL came on took it to auto parts store... 2 codes came up
P0420: catalyst system. efficiency below threshold bank1
P2181 cooling system performance
I have the green sensor and I think its time to change the thermostat... My question is is it just a coincidence that both codes came up at the same time or is i possible it is a sign for something else... i just had the thermostat changed 10 min ago...CEL light is gone so i will wait to see if the cat code comes back.
Golf IV / Jetta IV :: Throwing P0300 / P0302 And P0303 Codes
The car doesn't seem to run that rough.
Replaced coil pack and spark plug wires with parts from O'reilly auto
16684 - Random/multiple cylinder misfire detected
P0300 - 35 -10 - Intermittent
16686 - Cylinder 2
P0302 - 35 - 10 - misfire detected - intermittent
16687 - Cylinder 3
P0303 - 35 - 10 - misfire detected - intermittent
I have searched and browsed multiple websites and threads to no avail. They all seem to be dead ends.
Golf IV / Jetta IV :: 2001 - Throwing Codes For Misfire / O2 Sensor?
So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.

I just has a gen 2 haldex and wireless controller installed. 10 minutes of driving around getting on it in sport mode, I feel a thunk from the back and when slowing down a few odd shudders. Drove it cautiously a bit more and felt fine, then harder and harder. Felt better, no understeer, seemed ok.
Got home and scanned with Vagcom, got the errors below, cleared DTC and scanned again, same errors.

Golf/GTI VI :: Foot Well / License Plate LEDs Throwing Error Codes?
Any LED I can throw in the footwells / license plate area that won't throw a code? I'm using the ones from superbrightleds.
They worked everywhere except the license plate and the footwells. Everytime I get in my car I have to see (check license plate lights!) and a bulb out icon.
Golf IV R32 :: P0171, P0101 And P0507 Codes Detected
Not real familiar with this code, given that my check engine light came on a couple weeks ago and they detected some errors and these codes appeared.
View 2 RepliesFord F-150 - 1997-2003 :: Throwing Code P0171 And P0174?
97 F150 4.6 200xxx on recent rebuild. My truck is throwing P0171 & P0174.
I think I tracked it down to leaky IAC and EGR gasket. I sprayed both with carb cleaner and the RPM's dropped.
My question is, wouldn't the RPM's rise instead of drop? I was under the impression that they would go up if the gaskets were leaking. Or did I use the wrong spray?
Subaru - Outback :: Off - Idle Stumble / Check Engine Light P0171 (lean) Or P0420 (cat)
My 2007 Outback has had an off-idle stumble since I bought it a year ago. Otherwise runs well and uses less gas than the 2000 Forester it replaced. I've had a smoke test done, cleaned the throttle body, replaced front oxy sensor, and used a variety of gas treatments. I don't trust the local Subaru dealer to work on my car and my local garage has run out of ideas, but suggested MAF sensor may work. Some days it runs better than others. Occasionally I'll see a check engine light P0171 (lean) or P0420 (cat) but it will go weeks between setting those.
View 9 RepliesGolf IV / Jetta IV :: CEL Recently Came On Throwing PO420 Code
I own a 2003 VW Jetta GLS 2.0L 4 Cylinder and my CEL recently came on throwing the PO420 code (Catalyst System Efficiency Below Threshold (Bank 1)). So I replaced both the upstream and downstream O2 sensors. Well just one day after replacing the sensors the CEL came back on with the same code. I was wondering weather or not I should replace the whole catalytic converter or if there was anything else I should try. The car runs fine, exactly how it did when I bought it.
View 22 RepliesGolf IV / Jetta IV :: 2003 - Throwing P0113 Code?
I have a 03 GLI 24v VR6 thats throwing a P0113 code, which is for the intake air temperature sensor. The sensor is part of the MAF sensor, ive tried 2 brand new BOSCH MAF sensors yet the same check engine continues to reoccur. Is there anything else that oculd be triggering it to come on? Is there anyway to bypass/disable it through vagcom?
View 8 RepliesGolf IV / Jetta IV :: Getting Error Code P0420 Intermittently?
I keep getting the error code P0420. Cat below threshold.
I have replace both the front and rear O2 sensors and we reset the check engine light. While driving through the cycles to reset the sensors for them to be ready for DEQ, the check engine light came on again.
I am about ready to buy the Cat Converter, but it is really expensive and if there are any other things that I can try before replacing the Cat I would like to try that first. Any other issues associated with that code, or should I just replace the Cat Converter as my next step.
Golf IV / Jetta IV :: Check Engine Light Came On And Went Away - P0420 Code
MK4 GTi - My check engine light came on a few days ago and when I checked it, it pulled code P0420.
Just this morning, the check engine light went away.
Is this a common issue? Or should I go get it checked just in case?
Golf IV / Jetta IV :: Downpipe Stud Broken And Code Is P0420?
So I recently bought a GTI and started to fix a couple things. It has a P0420 code so I bought a new downpipe to install. Noticed the stock one was missing 1 of the nuts and the stud had broken off. How get this out? Do I need to remove the turbo? Looks like I do need to remove the turbo to use an extractor set.
View 7 RepliesGolf IV / Jetta IV :: 2003 - Got Error Code P0420 And P0141?
I just bought a 03 2.0 and ive been trying to fix her back up, she is almost there, just waiting on my first gear getter from diesel geeks and trying to figure out why these codes (p0420 and p0141) keep coming back on. Originally it was just a p0420 code so i took out the upstream sensor and cleaned it, then i took out the backstream and after examining it figured it should be replaced.
I went and bought a new one and replaced it, within the next 2 days the check engine light came back on throwing the original p0420 code along with p0141 this time. So i took out the new down stream 02 sensor and took it back to autozone and they swapped it out with a new one for me free of charge. So i put the newest 02 sensor in and then within 2 days, both codes p0420 & p0141 came back on. Two 02 sensor heating wires being bad i feel is a pretty slim chance. What is possibly the cause for these two codes repeatedly being thrown?
