Golf IV / Jetta IV :: Idle At 1200 RPM Way Down To 800 When Starting And Engine Is Cold
I have a 1.8t jetta that has a weird idle issue when starting and engine is cold it like to idle at 1200 rpm then will eventually work its way down to 800 rpm
I have no cel codes and have looked for vacuum leaks (but may have missed one) ,but if i start the car and it idles at 1200 rpm then i shut it down and start it right after it will idle at 800 rpm as normal.
Its a 1.8t unitronic stage 1 stock everything except e type coils with plugs at .032, Also does not have much pull after 4000 rpm, not to worried but just may be part of the issue....
Golf IV / Jetta IV :: 2003 GLI Won't Turn Over When Cold Outside
When it's cold out, sub-60F, the car won't turn over when the key is turned to start. Eventually, after repeated attempts, it will turn over and start like normal. My battery is fairly new. My first guess would be a starter relay issue but according to the manual I have there is no starter relay.

I have a 2003 golf gti 1.8th awp with 160k miles. I was due for a change so I grab castrol edge 0w40 the euro formula like I normally do but the stp filter was on sale with it so i used that. a week later the low oil pressure light comes on when the cars fully warmed up but only at idle I can review it above 1000 and it'll go away. I decided to change the pressure sensor sense it's cheap and easy nothing. I also went to a Bosch filter which I had before same thing light comes on only at idle.
So I decided to drop the pan and clean the pick up there was some crap in it wasn't to over clogged. I did little notice plastic piece surgery in the pan but when I first got the car the dipstick was deteriorating and I know a few little prices fell in there. Also noticing a fairly clean looking motor and oil pump so I don't think sludge is a issue. Anyway I decided to try mobile 1 0w40 euro formula and I read k&ns 3001 filter is a good oversized filter. Anyway light still comes on only at idle, what next?
Addition info the the car it's a stage 2 apr tune with euros ports pcv hoses turbo inlet pipe 42dd's catless exhaust recently had a leak in radiator so replaced that and the fuel pump went out within the last month or two
Golf IV / Jetta IV :: 2003 - Oil Light Blinking In Cold Temps
So my oil light was blinking on 03 jetta 1.8t for a week or so because of the cold temps where i am once my car reaches temp if you turn off the car and turn it back on my light stays off. i had a oil change recently hubby did that plus i had all my fluids checked and had to have my dipstick tube replaced because it broke.
I had a mechanic who lives in my complex take a look at the car and he said everything is running fine. So today I started my car then my oil light went on again it has been a lot colder than the past few days could that be the reason? My cars not overheating at all but once it gets to temp if you shut and turn the car back on the light goes away. My car only has 88 thousand miles on it and we used the proper oil for the oil change..
Golf IV / Jetta IV :: 2003 2.0 Won't Rev Over 3k / Start And Idle Rough
I have a 2003 2.0 gas Jetta (181k miles, automatic.) that won't rev over 3k, starts rough, idles rough and wont stop setting a P0341 cam position sensor code.
The car was not running when I got it, I replaced the coil pack and it ran but not over 3k. Cleared codes, it sets the P0341 immediately.
Had timing belt, water pump, tensioner and cam pos sensor replaced. Still, sets p0341 code, starts rough, idles rough and wont rev over 3k.
The throttle servo makes a little noise when actuated, shop thinks this is my demon - suggests replace throttle body. This car is for my son who will be taking it to college soon.
Golf IV / Jetta IV :: 2003 VR6 Rough Idle On Start?
I'm having a little issue with my 03' vr6. I've had the car for almost 2 months now, which it's pretty new to me, since about the time I got it, the car would sometime roughly idle on start, just for a few seconds, maybe for 10-15 seconds, and then it'll go back to idling at 600-800 rpm and being normal.
This has happened maybe 5 times since I've owned the car, and since then I've changed the battery, and cleaned my MAF. The other day when I started my car it (the rough idle on start) lasted for maybe 30 seconds, so it kinda scared me a bit.
Also there is no check engine light. Other than the weird idle on start, the car feels responsive, quick and there doesn't seem to be lack of power. This is the only mk4 gti I've driven fast in, so there may be lack of power and I just don't know it.
Golf IV / Jetta IV :: 2005 - Jolts Forward When Shifting From Park To Drive And Occasionally From Reverse To Drive
Recently I've noticed that every time when shifting from park to drive and occasionally from reverse to drive in my 05 Golf GLS, I would have to remain off the gas for 3-4 seconds otherwise the car would jerk forward. If I press on the gas ever so slightly, the rpm would go up to around 1000 then jerk. Why this is happening?
View 2 RepliesGolf IV / Jetta IV :: 2003 1.8T - Reverse Not Engaging On Cold Starts / Code P0732
I am having a problem with my MKIV, @ 182k. I think problem first arose a couple months ago when reverse began not engaging on cold starts, so I would have to sit there 5-10 minutes waiting for car to 'warm up' enough for reverse to engage. This led me to taking it to a local tranny shop who I asked to change fluid only, which they did. Problem persisted however, but forward driving was noticeably much smoother. If that matters. I gave up on it, since I knew it was only reverse messing up, and started parking in reverse overnight etc.
Simultaneously I had a code for P0420/P0411 (the SAI incorrect flow crap which causes catalyst inefficiency) so I went ahead and swapped out the cracked SAI plastic hose leading to stock airbox, after doing so I reset the CEL and ran the car. And it ran like crap, I think it was in limp mode (i had never experienced this in my Jetta) from what Ive read, but not sure. So, I pulled to the side, and restarted car, let it sit, same problem. Finally, after 3-4 cycles it threw a CEL, which ironically FIXED the problem. It ran fine from then on. Made it home, hooked up scanner and CEL code was P0732, which I read elsewhere is a 'Gear 2 - Incorrect Ratio' meaning 2nd gear is messed up somehow.
So, overnight I reset CEL and today in the morning I let it idle for 10 minutes before taking off, immediately same issue, where car will not accelerate/ change gears it seems. Went back straight home, waited for CEL to display, and VOILA, runs fine again. Same code P0732. Running fine as of writing this. Problem only arose after taking a swing at SAI code and reset of CEL's. Once CEL lights up its fine.
Golf IV / Jetta IV :: 2003 - Rough Idle About Every 30 Seconds At Low 700 Rpms And Bounce Up And Down A Little
Random rough idle about every 30 seconds at low 700s (rpms) and it'll bounce up and down a little. The code was p1515 (No CEL or other lights have come on yet) which is something about the intake manifold valve and there is an air-shooting noise that is pretty loud but just sounds like air that's being lost somewhere like maybe a leak and that happens when i rev right before you can hear the engine rev the air/shooting noise occurs. I don't really think I'm losing power but I got the car recently so maybe I am and don't notice it. If this is a common leak or something with the intake manifold valve let me know,
View 2 RepliesGolf IV / Jetta IV :: 2003 Volkswagen 1.8T GL - Ticking Noise / Loud Idle
I own a 2003 VW Jetta 1.8T GL Model.
When in Idle the car starts to make a ticking noise and tends to get louder the longer it sits. On top of this the idle does seem louder than when I first got the car like a constant purring noise if that makes sense. I am only able to hear the ticking while in idle, but the purring noise is continuous even while driving. I'm not sure what the problem could be but have the necessary funds to make some repairs on my car though not tons.
My car currently has approximately 128,500 miles on the engine. I'd like to keep this car running for a long time.
Golf IV / Jetta IV :: 2003 - Slight Growl Bearing Sound At Idle?
Not sure where to even start this but ill try to keep in concise. 03 gli 24v 6 speed. 125500 miles. At about 123500, i start noticing this slightly growly bearing sound at idle, without the clutch pedal pressed. When you press the clutch pedal, it goes away. Waited a bit, and at 125k, i replaced the clutch, flywheel, and throwout bearing, thinking it was a bad throwout bearing. It wasnt that.
Next, after more research, it seemed the 02m 6 speeds have had some issue with input shaft bearings wearing out making similar noises. So, pull the trans back out, and send it to APTuning in PA. Have new input shaft bearings, upper and lower pinion shaft bearings, and diff bearings put in. Even though they said they saw no major wear to be worried about in any of them. And here we are, left with the same noise.
One of the guys at APTuning said they had a case with one car where the thrust bearings wore so bad it made for a similar condition. Where the car would make unpleasant noise without the pedal pressed, and would go away when a load was put on it with the pedal. SO, i guess what im asking is, is there validity to that? What are the chances my otherwise seemingly fine 24v has this issue and end play is so bad that is causing this noise?
The noise gets NOTICEABLY louder when the car is hot. Its almost silent on cold starts. But after 15 miles or so it can be heard almost voice level with the windows down when you're stopped and idling; it really hurts to drive it being a caring owner hearing it. The motor is still in the car with all accessories so i can't check the end play scientifically. But to be fair, if this is plausible, and is the issue, i dont think it'd take precision to tell.
I'm so deep into this, and thought I've ruled out everything yet the noise persists. Really at a loss..
Listen around :30 where I start to cycle the clutch pedal. When I press it, you hear the main shaft "spin down" and the noise go away. When I release the pedal again, you here the clunk and the noise again. Its also been sitting for 3 hours. Good bit louder when hot [URL] .....
Golf IV / Jetta IV :: Car Is Too Low To Drive Up Onto The Lift After Alignment
So I installed coilovers a short while ago and now I need an alignment bad (obviously), but when I took it to get aligned, I was told my car is too low to drive up onto the lift , so I was wondering if I would be able to adjust my coils to a better height and then after the alignment just drop them back down a bit, it won't be too major of a drop back down but I just want to make sure I wouldn't be wasting my money. There is a place up the road that will do the alignment at my current height but for a pretty steep price considering how low my car is.
View 10 RepliesGolf IV / Jetta IV :: MK4 GLS 2.0 Shuddering When Drive In Reverse
I bought a MK4 GLS 2.0 5 spd with 200,000km on it back in february, It currently has 208,000km on it.
Whenever I drive in reverse, I get this loud shuddering/rattling noise with a slight vibration. I've noticed that it is louder from a stop and when the clutch it partially depressed accelerating,but pretty much goes away when the clutch is let out or when coasting.
It is sounds like it is coming from behind the front seats to the rear of the car. It almost sounds like the rear shock mounts are rattling. I also sometimes still here a slight knock, similar to the sound of worn sway bar bushings, but replaced those a few weeks ago.
I also get the same knock whenever I screw up a shift and the engine moves. I also considered and engine or transmission mount but i don't really get any vibration through the steering wheel other than a small amount which could be attributed to the poly dog bone bushings.
About two months ago but I replaced the RR shock mount with a new one. The old one looked fine. I replaced the RL shock mount with the one that I removed from the RR side.
Changing the shock mounts made no difference but I noticed that I could easily compress the RL rear shock with my hand. Could worn rear shocks be causing this noise/vibration? I've searched but I can't find an explanation besides the shock mounts.
I have replaced a few suspension components in the last few months:
-rear beam bushings in august
-front sway bar bushings a few weeks ago
-RR rear shock mount (new)
-RL rear shock mount (used from other side, but looked fine and replacing it made no difference)
-energy suspension poly dog bone bushings about six months ago
I don't think the car was really maintained that well due to it having original sway bar bushings and having tires that were worn very unevenly due to the rear beam bushings when I got it.
Golf IV / Jetta IV :: Getting P1128 Code - Can't Drive
P1128. Have had the code over and over!! No vacuum leaks and I've been through 2 MAFs. I've cleaned the throttle body, changed intake manifold gasket, changed plugs and wires, and put a new air filter in.
The code comes back every few months or so and the car becomes undriveable. Last changed my MAF back in December and the code is back already. What am I missing?
Golf IV / Jetta IV :: 2002 - Overheating When Go For A Drive
So my 2002 Jetta 1.8t is overheating. The water pump was bad. Replaced. The thermostat. Replaced. Radiator. Replaced. Radiator cap. Replaced. We're running out of things to replace! I'm ready to go to a junk yard and get a new block! We've tried about 100 magical "ways to burp it" with no luck. We even tried running it without a thermostat. Without the heater core. EVERYTHING.
The car runs at operating temperature at 4 RPM. But when we take it for a drive, it overheats. There's no heat with the thermostat in unless you rev it at the high RPMs. As for the hoses, top is hot, bottom gets hot. As for the car, it runs beautifully. It gives no codes. No smoke either. Nothing in the oil, nothing in the coolant so I don't think it's the head. It just overheats. This has been FAR too long.
Ford F-150 - 1997-2003 :: Rough Idle When In Drive
I bought this truck used and when it's in drive the engine idles rough and seems about to stall when the ac is on at a stop sign or red light.. I've tried it w/o the ac on and it seems a little better but not as smooth. Idle in park is fine.
When I should start looking? Spark-plugs? spark plugs wires, disturber cap, fuel filter etc...
Golf IV / Jetta IV :: Battery Light Came On - Car Went Off After 10 Minutes Of Drive
A week ago before I left for h20 my battery light came on, i drove for 10 mins and it went off. I also had a battery test and alternator test at that time and everything showed up ok. I drove 800 miles all good. Last night the battery light came on again, I was far from home so just tried making it back but the car dies on me. Before it died the traction and abs light turned on, the lights dimmed, when I gassed it the lights would get a tiny bit brighter. Also my gauges got stuck at the rpm i was driving at and 70 mph, even though i came to a stop already.
When i tried to gas the car it was backfiring, sometimes i couldn't even give it gas. Only way to start the car was to jump it, then i can drive a little before the car died again.
I drove with my battery box off the highway because highway patrol said i have to and got towed how from there last night. The ALTERNATOR AND BATTERY WERE CHANGED a year and a half ago apx 12000 miles, all oem equipment for the alternator. The serpentine belt and tensioner on top have also been changed and serviced.
Golf IV / Jetta IV :: 2000 - Car Starts Out In 3rd Gear When Put It Into Drive
I've been having 2000 Jetta GLS VR6. It has an automatic transmission and lately I've noticed that when I put it into Drive, it starts out in 3rd gear. In other words I've lost 1st and 2nd gear when put in Drive. When I manually put it in 1st gear with the shifter, I have 1st gear and all the way up to Drive. The issue just seems to be while in Drive (D)
I've tried the Automatic Transmission Reset :

Perhaps I'm not doing it right as I can't seem to see any switch under the Gas pedal, just a round piece of plastic that protrudes an inch. I've even removed that and still see no switch.
Golf IV / Jetta IV :: ARB Rubbing Drive Shaft After Lowered
Had the common problem of ARB rubbing the drive shaft after I lowered an extra 15mm - It didn't rub before I went this extra 15mm. I got adjustable drop links on and they also didn't work. I basically told the garage to sort it out and they put standard drop links back on (not genuine) and also new wishbones because I needed them. Got my car back and the rubbing was even worse. So I raised it back up the 15mm, to where it was before the rubbing started, yet it's still rubbing like crazy. I'm wondering if the new wishbones may be causing this because of new bushings or something and it all being tighter. And also what am I supposed to do? I shouldn't have to buy a whiteline ARB because it wasn't rubbing at this ride height before the wishbones and drop links were changed.
To summarize:
>Lowered car extra 15mm, rubbing started
>Drop links and wishbones changed, rubbing is worse
>Raised back to the point where rubbing started and still rubbing just as badly.
