The car will start up fine, run for 10 - 20 min and stall. I will try and restart it but i takes atleast 7 or 8 sec of the car just turning over before it slowly fires up. Which results in a high idle 1200-1400 rpm and the car stalling another 5 min later.
Ive fixed my o2 sensor the wire was cut, replaced the fuel filter, and got a eurojet lower pcv hose for the vacuum leak i found.
GTI 337/20th Anniversary :: Overheating Indication On Temp Gauge / CEL On But Car Running Fine

View 4 RepliesGTI 337/20th Anniversary :: Bog Down A Lot / Rough Running - Complete Power Loss On Highway
About 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 ??
GTI 337/20th Anniversary :: Brake Lights On Both Side Not Working But Running Lights Do
I'm on my way out and someone on the road just told me that my brake lights are both out. My rear running lights do work. Is this a fuse problem? What is the number where this fuse is located?

But we have an 03 Golf GTI. And the ECM went bad. So we got a new (used) one. But the problem was that it wouldn't communicate with the VAGcom. Replaced the ECM now it communicates. But our problem is the anti-theft code. I am not sure of the secret "code" the dealer is supposed to give you. It wasn't supplied to us. Looking for info on reprogramming this part of the immobilizer?

So, it's been 8 years with this awesome car. Still enjoying every day. Over the past year or so, I've noticed my engine get gradually louder and louder. By that I mean, the overall engine noise at low RPM. It's a mechanical kind of noise. Clicking, etc. The engine has 101,500 miles on it.
For the past 2 days now, this noise has gotten dramatically louder. I've tried to capture it in the video below. Might have to listen with headphones. The noise is most noticeable at idle and then goes away after about 2000 RPM. You'll see. What this might be? Btw, there is no reduction in the performance of the car.

GTI 337/20th Anniversary :: 2003 - Headlights Going Out Repeatedly
I have probably had problems with my headlights and brake lights for like the longest time. I swear I change out more bulbs more than anybody I know. When one head light goes out I switch it out, only for another to go out.
Recently both head lights go out back to back so I decided to wait to change them out. And im sure my high beams are out also since i used those when i drive at night which isnt to often. I still haven't changed them out, because I dont want to spend more money on bulbs only for them to go out again.
I've probably had this problem since ive had this car. I was wondering what I should do or what i could look into to try and fix the problem. I have a 2003 VW GTI 20th Anni.
Ive had it since birth so I would like to get this problem resolved. Haven't had any major problems except for a few electrical here and there. And ive kept it serviced up to date.

View 20 RepliesGTI 337/20th Anniversary :: Smoke Coming From The Engine
Car was started for the first time after the radiator was flushed and new coolant was put on it. The car was just jumped and charged after was brought from a copart auction. Now my brother said that everything looks smooth, no xxxmas tree in the dashboard, idle is steady, engine sounds good.
Now here comes the thing, the temps of oil and water are at a proper level. When he steps on the gas pedal a few seconds later there is some sort of smoke coming out from the back of the engine (exhaust manifold, turbo, intercooler stock pipes from the SMIC) My question is cause he's not a mechanic and he will arrive tomorrow. crack manifold, shot turbo or some leak in the hoses?
aBtw the car has 105k miles.
