View 4 RepliesNow I'm back and just picked myself up 2002 Golf GTI with fairly low kms for its year. Anyway when i test drove and checked through it all everything seemed fine. Basically she won't start 1/6 times. So for example of the amount of usage she had today:
AM - Drove to work this morning, started fine from cold (its just come into winter so probably around 12 degrees Celsius).
PM - Drove home from work, started fine from cold
Evening (3 hours approx. after driving home) - started fine from cold, drove 5 mins, stopped at gas station, started fine and drove another 5 min then stopped and parked.
After parking, i decided to move her closer to the building for security but when i cranked her she would turn over but not start. Tried this 2 or 3 times (probably flooded the engine).
After about 1 1/2, jumped backed in, started first time but took a few seconds to start with foot slightly on gas. Checked the fuel pump, i can hear it switching on so can rule that out.
I'm suspecting its a battery issue based on history (has had all the major service parts done timing belt, fuel pump etc) and for the majority of its life, its actually just sat in a garage, according to the dealer (old guy that lived and worked in the city owned it before me) and that this just needs replacing. The battery doesn't look old however under the bonnet it is stupidly clean so might not be an indication of anything.
I haven't had a flat battery for a while though but from what i remember, a flat battery just clicks or even struggles to turn over? Any simple things i can check myself? Just went downstairs to check fuel pump, thats switching on and car started fine 4 times in a row.
Mk4 2.0 GLS 2002. I'm guessing the title clearly introduces the problem, I think I should be getting around the 21MPG mark in city with my Golf. I have changed alot of things to try and improve the mileage but it's not getting any better.
I've changed the Air Mass Sensor, both oxygen sensors, the catalyze, spark plugs, done some work to the gear, fixed leakage in the automatic clutch, and I have done some deep cleaning to the engine.
IMy golf 1.8t 2002 shutdown at idle and when you started again she started again and runs fine you stopped at light wait few seconds the engine shutoff.
View 11 RepliesSo i got a 2002 gti 1.8t awp . Wont start unless I crank it about 2-4 times. Also noticed a bit of a grinding/high pitched noise when cranking. when the car starts up it idles perfect, doesn't die , drives perfect etc...
Eventually i got the car scanned. & got 2 codes.
P0341 : Camshaft Position Sensor A Circuit Range/ Performance B1
&
P0230 : Fuel Pump Primary Circuit Malfunction
So I went and bought a Fuel pump , Camshaft position sensor & Even a new starter. Nothing fixed it. & the problem still occurs..
Heres a video of me trying to crank it ; [URL] .....
I've been having this problem for a few weeks now and its getting real bad. When I'm driving along at normal speeds my car will cut off on its own. Also when I'm slowing down the car will jump up 5-600 rpms and at utter and shake a lot and every other time it'll cut off. I've replaced the maf and nothings changed. I'm really hoping it doesn't have to do with the transmission. The car has 241k on it .
View 3 RepliesI have an 02 GTI w/ 1.8t and 5spd. I was in the drive through and all of the sudden the ABS, ASR, and seatbelt lights came on and the battery light is randomly blinking. I got home turned the car off and went to restart it and when I turn the key nothing happens. I should also mention I recently have 2 cels for p0171 lean condition and bank 1&3 misfires that developed after I replaced a bad injector. Where do I even start?
View 7 RepliesI was recently driving home when I made a left hand turn and the car died. I had the timing belt and water pump replaced 1,800 miles ago. It sounds like a timing issue to me. The last time I had timing issue it wouldn't run. This time it runs. Attached is a video of me starting it with the camera looking at the timing belt. The noise I heard made me shut it off. I did not want to cause more damage.

So today I was driving my car and everything was fine. I get to a freeway off ramp. I put it in first and it goes like normal I shift from first to second and then into third when i shifted into third, I hear a grind sound like I miss shifted or something. I continue on and when I get to a red light I go to take off in first and nothing...The car wont move!! I have the clutch all the way out and its in gear and nothing... I can have the car running and the clutch out and i can shift it in any gear and nothing happens. I have a spec stage one and an 8lbs smf in the car and before i could hear clutch chatter and now when i have the clutch out I don't hear anything? What is causing this?

View 1 RepliesI recently picked up an 02 Golf with a 2.0/5-speed. It's just a plain-jane model without all the bells and whistles. My fans and A/C aren't working. I can deal with no A/C but the cooling fans are kinda important. I did all of the trouble shooting. Both fans work on low and high when jumped at the radiator temp switch so my fans aren't the problem. I replaced the temp switch with no change. My OBD-II scanner shows that my actual coolant temperature was about 10 degrees off from my temp gauge so I replaced the temp sensor too. The timing belt and water pump were both changed about 5K ago.
I borrowed a "good" FCM from a buddy's car and that didn't work either. I went through the troubleshooting diagnostics for the FCM harness and see that I do not have continuity between T14/14 & T14/5 on the harness side. This indicates that the "F38 Ambient Temp Swicth" is possibly my culprit. Everything else checks out good on the FCM harness. Where is this switch located? I've searched online and found nothing specific to my 02. For the sake of testing can I jump these 2 wires for continuity to simulate a working switch? From what I've read this ambient temp switch disables the fans and A/C when air temps are below a certain temp. My next step is going to be wiring in a variable speed fan controller if I can't figure this out .....but I'd rather not get in to that if I can get the factory setup working.
When I turn the key in the ignition, almost nothing happens. There is no resistance when turning the key. Accessory power works (interior overhead lights, dash back lighting, door open sound) but no dash lights or headlights (just the front passenger parking light comes on). Tried to get a jump but nothing happened, not even the headlights came on. Haven't tried push start yet. I suspect an issue with the ignition switch, but I found another thread that suggested it could also be traced to certain fuses.
View 3 RepliesSo I picked this clean mk4 up and its my daily but what to do. It already has new coilovers and little things here and there.I recently noticed my e brake doesn't work I tried adjusting but no luck what can it be the cables seem to be intake. Also if I get a bov does it make my gas mileage crappy?
View 7 Replies2002 vw Jetta sportwagon automatic trans, 151k, no previous issue with the transmission like this. the new issue is that the transmission is slipping at 20mph. what I would guess is 2nd to 3rd (3rd-drive)gear, the transmission "slips" and over revs, I take my foot off the gas and it engages.
I have no more issue accelerating after that. it only happens at exactly (on the speedo) 20mph. hopefully it is only a transmission fluid issue.
As a sidenote. my car will periodically lose power when the engine is cold with no rhyme or reason. the car power drops (on a flat or an incline) for about 2sec then back to normal. its been happening for a year or so.
So last night I bought a rather nice low mileage tiptronic jetta for a good price that supposedly needs a new transmission (girl was quoted $5k to fix at a shop). The car starts right up and moves under it's own power...for about 2 minutes. I haven't actually driven the car but moved it forward and reverse a few times in the parking lot last night. Got out to look at something and when I got back in there was zero response from the tranny, any gear. Engine just revs. Seems a bit different than the usual slipping in gear or violent shifts these trannys are known for.
View 4 RepliesI drive a 2002 Jetta with a turbo engine. In the past 2 months, my car has 'powered out' or shut down while driving - I can't accelerate, it is hard to steer, doesn't really brake well and although the dashboard lights remain on, my car dies on me. So far, I have been able to restart the car with little problem and she usually starts on the 1st or 2nd try. My dealer/mechanic had the car for a day, test drove it numerous times, checked the computer, battery, connections, etc. and can find no reason for this behavior. The last time this happened, it was raining outside; I don't remember what the weather conditions were the first time this happened. I have kept the car well maintained throughout the years.
View 3 RepliesI have a 2002 Jetta 1.8t w/tiptronic that my wife has been driving for a long time. The other day it stalled on her, which it has done before but this time it wouldn't start. I had it towed to the house and when I turned the key it sounded like the starter was spinning but not engaging the flywheel. I took the starter out and it tested fine. I put it back in and still the same result. I bought a new starter and it is doing the same thing. The battery is fine and the flywheel turns fine manually. I am stumped about the not cranking issue. I do realize that the stall and starter problem are not related but unless I can get it started I can't see how I can take care of the stalling issue.
View 1 Replies2 weeks ago my fans stayed on all day and killed my battery. Did a bunch of research and found that the FCM would be a possible place to start. FCM was literally in pieces under the battery. Replaced it with a new one. Still no fans. Popped open the fuse box on top of the battery. Fuse closest to the engine was blown and the plastic had started to melt. Bought a whole new one of these and replaced it. This time I read about the AC test with the car off. AC works (which is a pleasant surprise) but only the big drivers side fan works. The small passenger side fan never turns on. Turned the key off and the fan stops so that's good, I think. Ever since then my battery gets drained if it sits for so many hours.
Everything I read points to that fan going bad and becoming inoperable. But is that what is causing my battery to drain? Today I pulled the fuse nearest the engine when I got to work to see if my battery stays charged all day. Well as of right now it will not even turn over. Went out after work and it turned over 6 times but did not start. Started to jump it using my buddies car. Let it charge for 20 minutes and now it wont turn over. Have dash lights. Glow plug light is working as it should. Headlights everything works. Charged up the battery. Have 13 volts at the battery. Doesn't make a difference. Still will not turn over. Going to pull my battery tray after work and see if I can see the solenoid. Will see if I have any power there. Can I see the solenoid from the top of the car? Probably not...
What is a good way to get a lot more horsepower for my jetta. Its a 02 Jetta GLS 4cyl 2.0L. I already put in a cold air intake in it and am adding a stage 2 clutch. But I want to hit a higher threshold of horsepower what is a good way to do it. I am looking to put somewhere around 10 grand into it with in the next year.
View 9 RepliesIn my 2002 audi a4, I can go 100 miles per hour no problem, but on my mk4 gti 1.8t 80 mph is like pushing the car in fifth gear, near 3500-4k rpm, with a shaky steering wheel
So I was wondering what the actual top speed, or if this is normal. I feel like my car going 90 would be pushing it to it's limit, regardless I still love my vdub, and will continue to work on her
I have a 02 gti 1.8t and my a/c stopped blowing cold out of nowhere. I added r134 and it didn't make a difference. Changed the switch near the firewall in the engine bay and it still did nothing. Compressor clutch kicks on when a/c button is pressed. Could it be I have a leak?car has 147k on it.
