Bought a MkIV for the fiancee 2 weeks ago (04.5 GLI 1.8T Automatic).. Great driving car, needs some minor love (really dirty, burnt out lights, etc)
After the first week, the coolant light came on
Had some G12 handy, topped it off (like 8-10 oz)
All good
2 days later, it came on again, added about the same amount
4 days later, it came on again, added the same amount
1 day later, it came on again, added the same amount
I am adding 50/50 mix, but haven't seen a puddle anywhere, Nothing looks wet, but then again its hard to see around the plastic cover ...
Golf IV / Jetta IV :: 2005 - Oil Cooler Randomly Start Leaking?
I've got 149,xxx miles on my Golf TDI. Took it by a local shop for a routine oil change and since then, it's just been puking oil from the oil cooler. I took it back to the shop and the mechanic even pointed that out. Some red flags here; Timing is too shady. This happened literally the day after the oil change. He also told me that he won't use customer-supplied parts for liability reasons. Seems believable enough, but why would this part just choose to go wrong now?
This is my first time at this shop too and I've never really dealt with "bad mechanics" before but something about this isn't sitting right with me, and I'm not sure how to handle my next step properly. So what would cause an engine oil cooler to leak profusely just after an oil change?
Golf IV / Jetta IV :: Surge / Stutter - No Boost Leaks
Replaced my coil packs/sparks, and just got around to changing my N75 valve today. The rough idle issue is gone but now when I go WOT it boosts but goes from 15psi-12-13-12-14-12...etc. I've checked and there are no boost leaks. I do have a CEL saying I need a new bank 1 sensor 1 Oxygen sensor. If it is that, why did this problem arise as soon as I changed the N75 valve and wasn't present earlier?
View 1 RepliesGolf IV / Jetta IV :: Multiple Coolant Leaks In Three Months
My 2004 1.8T GTI is having a weird issue. It's had 3 coolant leaks in the past 3 months. Every time I get one leak fixed it goes leak free for a couple weeks, but then a new leak pops up in a new place.
First leak was a cracked coolant bottle. Second was a flange near the bottle on passenger side. The newest leak is on the driver side. Car hasn't ever overheated.
Golf IV / Jetta IV :: 2001 - Oil Sits On Top Of Transmission And Then Leaks Down Over The Starter
So I have an oil leak I can't figure out. 2001 jetta vr6 5spd. The bottom of the car is covered with oil. It appears to be leaking above the transmission. It will consistently drip at idle. Oil sits on top of transmission and then Leaks down over the starter. It doesn't have any coolant leaks. Is there anything anything in that area that could leak oil that bad?

2003 gti 1.8t. I'm having a problem with this engine code, it keeps coming back and when the CEL comes on the ASR light follows shortly and will then come on after every start up.
For the p0171 I've replaced:
Crankcase vent hose.
Y split running to the pcv
MAF
Coil packs
Spark plugs
Fuel pump
I also have done a seafoam treatment through tbe intake and ran a bottle (twice) of injector cleaners through the gas tank.
Nothing has fixed the code. I found cracks in the brake Booster vac line and had the line replaced (brake light would flash under boost, doesn't anymore). Can't find any other leaks except for maybe the secondary air pump (which I haven't replaced yet).
The OBD2 monitors all run. the EVAP and catalytic monitor won't click over to ready. I have a new pcv and a fuel filter coming in the mail in another vain attempt to fix the issue.
Golf IV / Jetta IV :: Slight Grinding Noise On Startup
I've noticed recently that on startup I'll hear a minor grinding noise after the engine has kicked over. Seems to happen more when the car is really cold.
View 24 RepliesGolf IV / Jetta IV :: Valve Clicking Sound At Startup
Just got this vr6 a week ago and noticed what sounds like a valve clicking, I thought maybe it was low on oil or something, so I just changed the oil and filter yesterday, clicking was gone from what i could hear. Start up today to go to work, clicking is back, I've noticed after the engine heats up the clicking subsides, but when you first start up I'm hearing it tick in the same area. Thinking maybe a intake/fuel cleaner next? My other 24v never did this. I've never taken it over 3k or anything until after it's warmed up.
View 2 RepliesGolf IV / Jetta IV :: 2001 - Grinding Sound On Startup
My 01 Jetta 2.0 recently started making a grinding sound on start up! had the crank sensor and the starter changed about a month ago and everything was fine but yesterday, for absolutely no reason it would make a horrible grinding sound on start up.Not the typical one where the engine starts and 2 seconds later it screeches (I searched) but while the engine is turning over it grinds. Once it didn't turn over at all just grinding sound. It's not all the time tho either?
View 1 RepliesGolf IV / Jetta IV :: 1999 VR6 Shaking Quite A Bit On Startup And When Turned Off
So my VR6 shakes quite a bit on startup and when I turn it off. I figured it was the dogbone mount. I did the clutch trick, jacked up the front end and engaged the transmission. Of course the engine shook a lot, in a forward to back motion, signalling the dogbone was bad. Shifts into and out of 1st and 2nd were pretty rough and i could feel it in both the driver and passenger seats during idle.
Well I just installed the ECS dogbone and while I can't really feel it much in the seats anymore, it still shakes quite a bit once the transmission is engaged. Low end shifts really haven't gotten much better either.
So I am thinking its either one of the other mounts, or the polyurethane bushing needs to be worked in. I am leading toward the former.
Golf IV / Jetta IV :: Wheel Leaks From The Area That Connects To The Wheel Base
I bought these wheels last summer from ECS Tuning - Alzor wheels for my Jetta. I haven't driven too much on them since I was deployed to Afghanistan for 9 months. I've been home 4 months. I think I have about 10k miles on them. The issue is that now one of them leaks. I took it in to be checked, thinking it was the tire. There is no rock rash, I haven't hit anything. The wheel leaks from the area that the spoke connects to the wheel base. There is no visible sign of a crack at all so I don't know what the heck is up. The paint looks fine from the spot it leaks from.

So I was on my to get some food and when started my car it was shaking really bad and had a ticking sound. I popped the hood and the engine was shaking violently, it drove fine one day to walmart and the next day started doing this. I am thinking it could be the coil pack because it was raining when I went to start it.
View 2 RepliesGolf IV / Jetta IV :: 2000 - Noise At Startup / Bubbles On Dipstick?
My 2000 Golf 2.0 started making a bit of noise on start-up and also if I rev it to say 2000RPM and then when the RPM goes back down it will hear some sort of "knock". After the car heats up as far as I know the noise is not there anymore.
This only happened today so I though I would check the oil level. It is fine but the dipstick was almost completely covered by air bubbles.
Golf IV / Jetta IV :: OBDII P0300 - Random Misfires Right On Startup
2000 Jetta MKIV ... 2.0L GL
I've been dealing with random misfire codes on my Jetta (P0300, P0301-P0304). I've since replaced the spark plugs, wires, fuel filter, MAF senor, & camshaft positioning sensor but the problem still persists. The misfires occur right on start-up and don't stop which is leading me to the coil pack being bad.
Golf IV / Jetta IV :: When Startup It Often Dies Soon After And Idle Really Roughly Until Warm Up
I have a 1999.5 jetta vr6, the CEL is on (p0102 MAF sensor circuit low or something like that...). When i start it up, it often dies really soon after and until its warm it will idle really roughly. I'll have to start it up between 5 and 15 times... Once its warm and about 190 F oil temp it runs just fine, but still has a slightly rough idle.
I have a new MAF sensor coming in, or if there are any other things i should check that might contribute to the problem.
Golf IV / Jetta IV :: Vacuum Pump Rivets Causing Noise At Startup
I have a raspy exhaust leak sounding noise when I start my 2003 GTi 1.8t that cuts off just a few minutes after I start the car and a fellow owner told me he thought it was a vacuum pump that has rivets that fail and allow the case to separate and cause this noise. Where this pump is located? This former coworker of mine said he replaced the rivets with long slender screws and nuts after removing the rivets but I lost contact with him and don't know where this pump is located.
View 2 RepliesGolf IV / Jetta IV :: Beep On Startup - Control Unit Improperly Coded Faulty
Every time I start my Golf there is a beep, the EPC light and ABS light come on and stay on, and the brake warning light starts flashing and continues to flash.
I have had the fault codes read and it came up with the following:
0414 Control unit improperly coded Faulty
0606 Yaw rate sensor Circuit defective.
What these faults actually mean and what might cause them? I'm quite keen to resolve the issue as anything brakes related makes me nervous, plus I do drive the car hard and use the 4Motion system, which I believe utilises the ABS system?
Probably worth mentioning that the car is fitted with a Series 1 Blue Haldex controller, in case that makes any difference?
