I have a 03 20th ae gti with about 84k just replaced the coil packs. driving on the freeway then power just goes away, press on gas and nothing. limp it off the freeway. Then it starts to die at idle and hardly turns over. car is pretty much stock. new clutch at 75k.

View 5 RepliesSo over the past couple months when driving on the highway I would notice that sometimes my car would lose all power and slowly coast to a stop, but then the power comes back on and I'm off after a few seconds. It happened again today and I notice when I do hit the gas when it decides not to accelerate my boost gauge shows that there is vacuum building up in the engine. It just doesn't make sense to me. Would my car be getting thrown into a limp mode? Or is it something to do with fueling?
View 4 RepliesAbout three nights ago I had a complete power loss on the highway and the car began to bog down alot under throttle (and surge at points as well although with no boost). It also idled very rough/erratically. When I unplugged the MAF it cleared up right away; Idle was smooth and it ran without hiccup but in safe/limp mode so very tame (again, without boost really, gauge shows it stays in Vacuum and never passes "0" or goes into boost).
I scanned it this evening and got 2 misfire codes and a MAF code, along with a code related to traction control which I noticed had activated as a result of this and could not be turned on (by activated, I mean the light came on, disengaging T/C). These things make me think it is MAF related, especially because I have bolt down Hitachi coil packs so I do not think that is what it could be in relation to the misfire codes (which I think may be old and needed to be cleared).
Fast forward to last night: I can pretty confidently say my MAF is not the problem and I think I saved an unnecessary expenditure. I was able to meet a friend with a 337 as well and his MAF did not change my car at all and my MAF ran fine in his car so I think my problems are something else. Although with the MAF plugged in my car runs very poor and unplugged it clears up and just runs "limp" (no boost and slow but stable) from what I tested this evening the MAF unit seems to not be the issue.
I think there must be a vacuum leak of some sort between the MAF and the engine which allows more air in than the MAF signals when plugged in which causes the issue. Also, I know a common thing to think is "coilpacks" but I have bolt down Hitachi coil packs so I would imagine that would eliminate those from being the failure they tend to normally be. Agreed ??
I have a question? I have had my car parked for about 2 1/2 months and I just started it this weekend and I've always noticed on our cars when we start them in the morning I think it's the secondary air pump that turns on, it sounds like a blow dryer.. It only stays on for about 10 seconds maybe. Cause when I started my car this weekend I didn't hear come on.
View 3 RepliesA buddy of mine has a gti that is not starting. he said the temp light has been coming on and the car would start to struggle. of course he kept driving. Today it came on and stalled out. Now the car turns over but wont start. I replaced the temp sensor (green plug) and it wasn't the issue. its a 1.8t with 80k on it. 2002. I am assuming its got to be fuel or spark.
View 15 RepliesOk I was driving home right know from work, and looking at the speedometer, i notice that my temperature gauge turns off (the needle goes all the way down). what can it be?
View 2 RepliesWhenever I go over about 50 MPH it starts shaking like the dickens. We have a lot of snow around so I'm thinking i just have messed up alignment from hitting snow chunks but who knows. [URL] ....
View 6 RepliesNoticed a loss in fuel economy after a CAI install??
View 10 RepliesI've had the car about 3 months now. It runs fine, never overheats, but I keep having to add coolant (every 2 weeks or so), but I can't see a leak anywhere.
I searched and found one guy that said it could be a bad expansion tank cap, and another that said it could be a tiny leak that only leaks when driving.
Anyway, when replacing my axle, I noticed this:
If that's dried coolant, where would that be from?
I have a 2005 mkiv GLI and my gas gauge, temp gauge, and information display stopped working when the car is running. They work when the car is on auxiliary but not while it's running. The lights all work on the cluster all the time but the needles don't move as soon as the car turns on.
View 3 Repliesso i bought projector headlights on my 05 gli and they were easy to install and for the first few days no problems, when the car was off and the lights on it was the parking (P) lights (amber lights), later if the lights were on and the car was off the radio would turn on, the A/C and the low beams would be on even if the hand-break was up, and i still have the DTR lights on. is it a short circuit problem???
View 2 RepliesCruise control stop working? mine hasn't been working for a while, and finally decided to ask. The light turns on in my cluster, but doesn't set when i try to set it.
View 5 RepliesI have trouble starting my GLI sometimes..its usually 1 out of 10 times. It will keep cranking and after a few tries it finally starts if i hit the gas a little bit too...
View 9 RepliesI bought my gti about a month ago and every time I warm it up in the morning or any time it has been sitting over a long period of time the rpms sit at about 1300 until about a minute and it goes under 1k ... I am not to familiar with this issue.
View 14 RepliesI have a 20th with 106k on it and I notice mostly my right front rubbing on hard turns. Suspension is totally stock other than a 28mm rear sway. Is it possible that's causing it or is my suspension just getting old? No spacer on the fronts.
View 9 RepliesHave a 05 GLI tiptronic. Every time while making a left turn there is a LOUD vibrating/rattling sound coming from underneath my shifter. Dealership told me it was my exhaust rattling since it was larger than OEM. That doesn't sound right at all.....
View 1 RepliesI have a 2004 Jetta gli 1.8turbo my car has 97,000 miles and the last oil change i did was with 0w-40 oil, can this cause my check engline light to come on and 2 cylinder misfires? should i change oil to 5w- or 10w- asap?
View 2 RepliesMy 04 gli makes a rubbing noise when accelerating thru hard left turns.. but weird enough i can take the same turn at the same speed in neutral and have no noise at all. I changed both front wheel bearings and cant seem to find the answer. I brought it to vw and they checked the whole suspension struts springs cv's tie rods ect. and they all checked out good they said. the car used to have a exhaust and i just recently put it back to stock, could the exhaust make the noise perhaps?
View 1 RepliesI just recently put in an APR chip on my o4 gli from one of their dealers, a day or two later I noticed when I try to accelerate fast my check engine light comes on and the car starts pulling back. That was almost a week ago, today I went back to the same place to get a short shifter, I told them the problem while I was there and they said it was my coil packages. I replaced all 4 and im still having the same problem...
View 2 RepliesI have a 20th anni GTI. I was driving down the road about a week ago going about 50 in 5th gear. all of a sudden when i go to give it gas my car starts lagging and the check engine light starts flashing on and off. I used a check engine light tester to figure out the possible problems and found that cylinder 2 misfired.
Spark plugs could have been the problem so i replace them. Nothing changed. so then i thought it could be one of the coils so i switch 1 and 2 aroud to see if there was a misfire on 1 now. still cylinder 2 misfired. I am starting to thnk it may be my catalytic converter. There's a funny spell coming from my exhaust. Like fire crackers or rotten eggs maybe.
