I have a 2001 jetta 1.8 turbo. when I turn the car off the cooling fans stay on and kill my battery. Ive been told it could either be a relay or temp sending unit but i dont know what one to tackle first, also my coolent temp stays way low almost as if the thermostat is stuck open.

This is kind of an odd ball problem since I have not encountered this before, but every time I turn my wheels full left or full right and start moving a really high pitched squeaking sound comes from the front of the car. Is it bad alignment or wear sensors on the brake pads rubbing? the brakes have a lot of pad left so i find that hard to believe.

I have 2002 2.0 Jetta that I totaled. I found a 2000 2.0 Jetta that had no engine or tran. I swapped the entire wiring harness with the engine and trans from 2002 into 2000. I even swapped the doors. The cluster, steering column and all. I am still in the process of getting a few parts to finish it up. At this point, the only thing not hooked up is the headlights and the radiator. I hooked up a battery and tried to get it to turn over today. I turned the key to the on position and the cluster did not do anything. The engine turned over very slowly in the start position.

View 2 RepliesGolf IV / Jetta IV :: Engine Temperature Rises When Heat Is Turned Off / Hard Pull
I have a 1.8T with 152kmiles
Recently, both the coolant reservoir 'Y' connector and the driver side coolant flange cracked and I was shooting G12 all over the engine. I've replaced both of the parts and the coolant temp sensor with a "green top". Reservoir was refilled with the proper ratio of G12 to distilled water, ran for a bit and topped off accordingly.
This morning I started my drive to work and the engine temp was at 0 for a minute or so and started to climb slowly to 190. It stayed at 190 until I took the exit to the highway and the temp slowly started to rise while I was at 60mph. I immediately turned around and went back home with the heat cranked to high. With the heat on, the engine temp would slowly go down but then rise again if I, A. turned the heat off or B. made a hard pull up to ~55+mph.
I popped the hood and the coolant was not boiling and I couldn't see/smell/hear any leak. could this be the thermostat or is this a water pump issue? I plan on taking the thermostat off and checking the pump empellars for any shards. I'm not sure but I do believe the water pump was replaced by my parents while I was on deployment.
Golf IV / Jetta IV :: 2008 - Makes Annoying Noise When Engine Is Warm And A/C Is Turned On
Mk4 Golf City*, 2008, gas, manual, sunroof. Canadian budget-model.
Mysterious noise like WOMMMMM, WOMMMM itinerantly: Noise is only when air conditioning is on and the engine is warm. I can feel vibrations in the brake pedal. *You can't hear the noise under the hood*. It is quite loud in the cab, though, definitely coming from under the dashboard.
I have stuck my nose in. I removed the glove box and listened to the blower motor, it seemed to be coming from further toward the driver's side. It will be like wmmmmOMMMMM WOMMMMM pause WOMMMM like something is vibrating too close to something else and the friction causes it to go back to where it was.
I hit a speed bump going a bit fast. I broke the small cooling fan somehow so it was just loose hanging on its hub. I had that repaired but the noise hasn't gone away. It seems to be getting more frequent but so far there isn't any indication of the car suffering. This is the second summer it has made the noise.It haunts my sleep.
Golf IV / Jetta IV :: Hard Time Starting / Engine Turned Over But Wouldn't Fire
2003 1.8t gti ... Today when I got in my car...it fired up perfectly normal but when I got in it from leaving school it took 5min to fire up. The engine turned over but wouldn't fire all the time as if the spark plugs were bad. So I bought new NGK spark plugs and had the same issue just a little bit ago.
I know the obvious thing would be to change the ignition coils but they're out of stock everywhere so I have to have them shipped. My question is is the ignition coils the problem? They looked a bit worn but nothing serious.

View 8 RepliesDodge - Neon :: 1998 - When Key Is Turned Starter Tries To Turn But Engine Does Not Spark
My Neon needed a water pump. At 204K miles the timing belt should be replaced also. The pump and belt were replaced. The motor started and the car drove about 1000ft. and stopped. There was no more spark. The car was checked to make sure that the timing belt is on correctly. The cam points to top dead center when the #1 cylinder is at peak and the crankshaft is at top dead center. Both marks align. When the key is turned the starter tries to turn but the engine does not spark. Electricity goes to the coil pack. 1998 Dodge Neon 2.0L SOHC 4 cylinder....

So I am not getting spark. Changed crank sensor and cam sensor still nuthing. I am getting no power to fuse 28 and 34. Also I am getting voltage on coil harness on pins 1 and 2 getting about 11.8 and on 2 and 4 getting 1.2. I am starting to think bad ecu?
View 3 RepliesGolf IV / Jetta IV :: 2000 - Oil On Spark Plugs?
I have a 2000 Jetta 2.8 VR6 (the 6-cyl) with 128k miles and I have oil on my spark plugs, only on one bank of the motor (the bank closest to the bumper, if that makes any difference). I am aware that it is most likely a leaking or worn out valve cover gasket, and I have a replacement and am prepared to replace it. What I need to know, and I can't find this exact part anywhere, is do I also need to replace the spark plug tube seals??? The gasket I ordered did not come with any tube seals, I can't find this part on any auto parts website at all, nor have I been able to locate anything useful on this, or any other, website. I know the 1.8 has plug tube seals, and they come with the gasket, but does the 2.8 also require tube seals? I imagine it would, but I just don't know.
View 2 RepliesGolf IV / Jetta IV :: No Spark - ECU Error Occurring
So driving on the highway my car died. It would crank but not start. Got it towed. This is what I have done to troubleshoot.
1. Swap ECUs. The car should start for a second and shut off because the car doesnt match with the ECU. Still just crank and no start.
2. Fuel pump still primes when I open the door. I also hear a weird air leaking noise when I reconnect the battery, but I think it comes from the fuel pressure regulator (which I think is normal).
3. Checked for current at the ecu wires, wasn't sure what to look for but it was getting numbers.
4. Battery had 12.1 volts running through it (Haynes said 12.5 but is that really much of a difference?
5. Checked spark plugs for spark. Pretty sure we did it right, but there was still no spark. We tried multiple times.
6. Scan car, get code P01314 twice (ECM error).
7. Try to clear codes, says Comm error.
Why am I not getting spark? and why is the ECU error occurring, because we tested with a new ecu, and there was still no start, not even for a second like there should be.
Golf IV / Jetta IV :: 2001 1.8t - Two Different Engine Codes
I have a 2001 1.8t beetle and doing some research to buy parts I came across two different engine codes. My trunk says I have a AWV engine but the cylinder head says AWM. This is really confusing as looking them up I get three entirely different options for this car.
View 6 RepliesGolf IV / Jetta IV :: 2001 VR6 Die When Engine Heats Up
I recently traded my mk1 for a 2001 jetta vr6 and though it was running fine the first few days, it now seems to die when the engine heats up. The check engine light and battery light turn on when it dies but turn back off when it cools down. I ruled out the battery variable by getting a brand new one (old one was 5 years old anyway) and the alternator is reading healthy voltages.
I've seen a lot about the crank position sensor (engine speed sensor) and I suspected that was my problem so I took it to an auto parts store and waited for it to die to pull the codes. The codes were P0201, P0205, P0203, P0206, P0444, P1473(?), P0418, and P0413.
The first ones said "fuel injector open circuit" and the others were all saying something about the evap system. I was wondering if these codes related to the crank position sensor or if there's something else I need to worry about. I may have stepped a little bit out of my league with this car and I'm at a dead end.
Golf IV / Jetta IV :: 2001 GTI VR6 Overheating - Engine Fan Only Operates With AC On
Engine will overheat unless I turn the AC on. The engine fan only operates with the ac on it seems.
Will not overheat unless in traffic for a while.
Would it be radiator thermo switch or the Fan Control Module?
Golf IV / Jetta IV :: 2001 VR6 Engine Cuts Out When Driving Around 50 Mph
So, my brother has an 01' VW Jetta 2.8 VR6 with a 120k miles on it. He was recently driving around 50mph when the engine cut out, he lost all power and all the lights on the dash came on. He didn't get any loud bang when it happened, it just cut out. He tried to restart the car but heard the starter try and nothing else.
He got it towed to a garage who said they suspected it might be a timing chain but they couldn't say for sure until they started poking around. He doesn't recall getting the loud "marbles in an" noise when the chain is about to go. They were quoting around $4k to replace the engine. Being as my brother is a poor student this isn't something he can do, plus he'd already replaced the radiator, tires and all that and I want to verify what is wrong with it.
Golf IV / Jetta IV :: 2001 - Engine And Computer Is Dead
I'm posting as a last ditch effort to try and rescue my 2001 Vw golf here's some quick details about the car then I'll go into the situation.
2001 Golf 1.8t 5speed
Euro customs stage 2 Aftermarket intake and downpipe
Still have front and rear O2 sensor and probably cat. Maybe..
Otherwise stock
201k miles
Okay so pretty much here's the rundown.. I was driving my car to work one day, then all the sudden lost complete throttle response to my car but was about to cruise at about 5-8mph to get to work and avoid towing. What is going on besides the EPC light was on and CEL was on. After work I discovered that the rear O2 sensor was hanging down and frayed.
Apparently from what I was told, that fries your ecu and put the car into a similar mode as mine. I then replaced the ecu with the euro customs ecu, I replaced the throttle pedal, and the throttle body since all I was getting was throttle codes. I am still not able to get rid of either EPC or CEL lights. The codes showing are p0638 and p2101. Yes I have tried to get the throttle body realigned or whatever you call it. However the vag com will not let you realign with the codes still in the computer which have been deleted but come back immediately.
The rear O2 is still unplugged and I still have little to no throttle response.
Golf IV / Jetta IV :: 2000 - Blinking CEL / Misfire / Oil On Spark Plug
2000 Jetta AEG ... An intermittent CEL light turned into a blinking CEL after a few months. Checked codes and it threw a P0303 (misfire on Cyl 3).
Pulled the plugs and found this:
There was oil dripping off of the plug from Cyl 3.
I last changed the plugs in July 2014 and only drove around 10k miles this past year.
When I changed them back then though Cly 3 looked like this:
Before I changed them back then I had an oil cooler gasket fail on the freeway and oil shot everywhere under my hood. Obviously oil is in there and it is causing problems.
I have read online and most of what I have read says that it's likely an issue with the VCG (Valve Cover Gasket) or the PCV (Pressure Control Valve) that is allowing oil to get to that part of the spark plug tube. I've also seen some non VW stuff talking about replacing the spark plug tubes.
Also it does appear that there is a little bit of oil around the threads of the other plugs but nothing getting to the all the way to the tip around the electrode.
I have pulled the plugs, wires and the ignition coil as well ... I'm ready for whatever. I am by no means a mechanic but I am capable of following instructions and doing what is needed. My problem is generally finding out what is needed to be fixed.
