Golf/GTI VII :: Low Boost - Revo Stage 2 / Check Engine Light Comes On And Performance Drops
I'm running a catless dp with the "low boost" Revo stage 2 (For 95-98 octane fuel)..
I've noticed when I put in rubbish fuel, the car runs fine and can hear the turbo spooling and pssting..
When I put in Shell VPower Nitro+ (Standard UK good stuff), the check engine light comes on and performance drops. I tried REVO but they stonewalled me. Thinking of trying the higher boost map..
Passat (B6) :: Check Engine Light - Air Intake?
I have taken my car into service twice because of the check engine light being on. They fix it and say it has something to do with the intake. It is now on for a third time. Obviously they are not fixing the problem. BTW, I have done no modifications to my car.

I installed an Injen cold air intake and 2 days later, the check engine light went on. I had it reset at the dealer and next day, again. Am I stuck with this or is there a way to keep it off, other than putting back the original air box?

I have a 1998 chevy silverado z/71 4x4. I had a water leak and had the intake manifold gaskets replaced. Ever since then, the check engine light comes on and it soots up the o2 sensors and the 4 plugs on the right bank. It may run good for a month or so and then it starts all over again.

This is the infamous error code many Accent owners might have experienced it. The code refers to "Too lean intake system". People try to replace all kinds of parts like ECM, MAF, O2 Sensor, TPS, Fuel Pump, Fuel Filter, etc. according to my research. I just bought a 2001 Accent and the P2188 light came on. I wrote an email to Hyundai Corp. Asking what would be the most likely part that will cause the (P2188) check engine light to come on.

Is there a difference in the engine sound between a stage 1 and stage 2? I like my stage 1 with APR intake as it is so I'm concerned I'll be changing it if I go to stage 2 with the intake.
View 15 RepliesGolf IV / Jetta IV :: Brake Vacuum Line Is Cracked After Check Valve On Intake Side
Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.
I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?

So recently bought vagcom to do a bunch of changes. Have a cel and the code is intake manifold flap position sensor. I have looked around and lots of ppl saying they took car in and vw fixed no issues blah blah blah. Well I have an issue. Cuz my car is not covered under warranty any more. And so I called local vw dealer and they told me I need to replace my throttle body? I thought I had to change my intake manifold and flapper motor.
View 24 RepliesGolf VI R :: Fuel Cap And Check Engine Light Came On
I've got a '13 CW Loaded 4DR. Its got just under 40K miles. Tune wise its the STG2+ from I.E., been tuned for maybe 10K miles. I was fueling up and I always tighten the cap correctly as Oregon has Fuel Transfer Technicians, AKA People who don't care whether your fuel cap is on right or not. So soon after the fuel cap light came on, pulled over and tightened it again. Light went away. Next fuel fill up, same thing. Third fuel up, same fuel cap light and then CEL came on.
Ive got VAGcom and checked for codes and got the small leak detected twice and then the large leak detected code. So I was thinking it was just a cap. I swapped gas caps with my brothers MK4 R32 to maybe get lucky and the code returns. Thats impossible for it to fall too, so I dug deeper. I checked the N80 valve as I remember those being an issue on 1.8t and old Flows, So i pinched off the line to it and performed the test again, and bam, no more code for large leak.

View 2 RepliesGolf V R32 :: Check Engine Light Coming On And Going Away
Coming and going away on the next to 2nd engine start. Usually coming on after a hot run, or a hot day. Stays off for a month, then comes back. Runs fine, no symptoms, no other noticeable abnormalities.
Besides Ross Tech, VCDS, are there other softwares or devices that work for diagnostic and maintenance purposes? I have no interest in re-programming factory functions, just maintenance.

Just popped on at exactly 97,600k, What could be some of the potential snafu's? Or is it just more preventative as it needs proper service. Will be taking it to Dealer, but just curious as to what it could be.

View 5 RepliesGolf/GTI VI :: Check Engine Light Came On / EGR Valve Bad?
So the day before my 20,000 mile service was scheduled my check engine light came on. I took the car into the dealer and told them the light was on. When I got the call that the car was done they said that the EGR valve was bad and they ordered me another one. They said that they cleared the code and that the part would be in this week. Since they cleared the light it has not come back on. My question is did I lose my Revo stage one tune in my TDI? The dealer never said anything so I didn't want to ask if they had reset my ECU.
View 2 RepliesGolf IV / Jetta IV :: EPC And Check Engine Light Come On
So for the past few weeks my check engine light has been on. I have a mechanic friend that scanned the computer and says i have a running lean code.... says it could be anything. So i have been driving the car since and now the epc light and drive train lights are coming on... car revs up and down and sounds like is going to die... got the car scanned and says something about the throttle position sensor... before all the lights started coming on i got my fuel pump replaced..... could a faulty fuel pump be the cause? I had my mechanic, clean the throttle body and it ran good for a few days... now the problem is back... I have a 2004 1.8 gti. Do i have to replace the throttle position sensor? Fuel pump again? New throttle body again? I read somewhere on here that a guy replaced some wires near the ECM and the problem went away...
