Golf IV / Jetta IV :: 2001 VR6 Die When Engine Heats Up
Apr 23, 2015
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.

So my temporary solution has been taking the gas cap off for 10-15 seconds, I suppose so that the tank can release any excess pressure. Then the car starts fine. This has worked pretty much every time. If I don't do this I could end up waiting for about 15 minutes before the car starts up again. They must be related. Is there anyway that the tank pressure isn't being vented properly?
I've replaced the thermostat, the ect sensor, the crank sensor, the fuel assembly, I've cleaned the injectors and replaced the fuel tank pressure sensor.

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.

Gauge/Sensor Problem ??? Great oil pressure on start up (40-60 PSI) but as car heats up, gauge SAYS pressure is dropping below 20 PSI. Dip stick says plenty of oil and filter is brand new. No knocking from valves either.

So here's the synopsis: My girlfriend's 2001 Ford Escape V6 4x4 with 196,000 miles had the check engine light come on two weeks ago. The code read : running lean and misfire in 4/6. Changed all plugs and coils, engine light was still on, still running lean and there's a vacuum leak. Changed all intake gaskets, light went out. NOW it's sputtering and the exhaust manifold turns cherry red (clogged cat). Changed the front cat & Y pipe, remove back cat. Also replaced muffler and resonator. Car STILL sputters and idles around 200 rpm. Now it stalls when turning around or coming to a full stop, and exhaust manifold still heats up enough to turn cherry red. Why this is happening?

2001 Jetta GL, 2.0L, 170k miles.... It won't start and it's not likely the fuel pump. After the car has sat for a while, I hear the fuel pump spin up when I open the door. It turns over just fine. I pulled a spark plug, attached it back to the wire, held it close to the head, and when the engine turned over, no spark. Is that still a valid test for spark? I haven't had to diagnose a spark issue for so many years, I don't know whether that has changed.

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?

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.

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.

The issue: Check engine light on. Codes pulled, and he's getting O2 sensor codes (aftermarket exhaust has caused that since he bought the car) and 17705 Pressure Drop Between Turbo and Throttle Valve. The car barely accelerates, and you can hear the turbo spooling, and the engine has small surges. I had VCDS going and went for a drive and noticed his N75 Valve duty cycle was stuck at 5.1% no matter what throttle position he was in. So we're going to the wreckers this afternoon and will pull an N75 valve? The DV is stock and appears to be in good condition, but if changing the N75 doesn't work then that's the next spot I'll look.

My girlfriend has a jetta and I work at a DODGE dealership in service. I recently replaced the water pump and flushed the coolant twice and replaced the coolant with G13 coolant from the local VW dealership. After I finished burping the coolant system of air bubble. After I finished I took it for a spin and being the speed demon I am, I don't hold back on the throttle. I noticed immediately the engine lagging and being extremely sluggish. I ran my shops snap on code scanner on it and I came up with cylinder 1 fuel injector open circuit. Cylinder 6 fuel injector limited power. And last but not least o2 sensor 1 open circuit. If your facing the motor I undid the left motor mount from the frame, lifted the car on a hoist and took the bottom side motor mount off of the motor. I took the cv shaft off of the transmission and lowered the car and jacked the motor up by the oil pan to expose the water pump for removal and replacement. I'm wondering if possibly the o2 sensor could cause the ECU to seize power to two of the cylinders to ensure no engine damage or if its 3 separate problems.

So my gf's check engine light on her 01 Golf flashes once in a while, and it misfires. But the thing is, it doesn't stay on, and it's once in a while (like once or twice a week). She has new spark plugs, and new wires. I have a feeling it's the coil pack, but I really don't know if it needs to be replaced until the check engine light actually stays on.

Just a few days ago I was driving and I noticed as I went over 35 mph my car would stutter and the check engine light would start flashing. And when I slowed back down the car drove fine. I'm wondering what the problem could be? Feels like the car is losing power. Car is currently at 119k miles.

I've had this car for awhile now and it's always had this weird whining sound coming from the engine.I had the transmission serviced thinking maybe that was the sound and it wasn't. I've taken off the serpentine belt and spun all the pulleys. I can't figure it out, I'm thinking maybe timing chain but I'm not sure.

01 jetta vr6 5 speed. Alright so earlier today I pulled out the driveway. (Hard) was in 1st gear around 3 or 4 grand and I stomped it. Got to 6 grand and hit 2nd. Took 2nd to 6 grand and let of around 60 mph. After that I short shifted into 3rd, 4th, then 5th. I noticed going into fith was hard. Had kinda rev match to get it. I stayed in 5th till I got to my destination roughly 4 miles. When I came back out to leave I had a hell of a time getting it into reverse. On my way home it was extremely hard to shift and now when the car is running I cant get it into any gear. This is what I did.
Car shifts fine with car off.
Car will not shift with engine running.
When started in gear with clutch depressed I can still let the clutch out and stall the car.
When starting car while in gear with the clutch NOT DEPRESSED the car jumps forward.
I can figure it out ove tried re adjusting the linkage. Nothing.

I have an '01 gti glx that I just swapped a motor into. I got the motor out of an '01 jetta glx, exact match AFP engine code.
I get cylinder 2 misfires mostly (high number) but I also get 5 and 6 intermittently as well as a P0300 code.
Sometimes I also need to hold the gas down just to get it to start even after the crank sensor.
The engine idles sometimes at 600 rpm but drops and nearly stalls after revving at all.
What I've tried so far:
working cam sensor from my old vr
brand new crank sensor
brand ned wires/plugs
new fuel filter
swapped injectors of misfiring cylinders from old motor
lined up the timing 3 times now and its still perfect
I know the coil pack works because it was on my old motor, which ran fine, just leaked oil.

I just got a 2001 VW Jetta. I got it with the Check Engine light on. Went to my local AutoZone to get a OBDII reading, got codes P0343 & P0321. P0343 Camshaft Position Sensor A Circuit High Input B1. P0321 Ignition/Distributer Engine Speed Input Circuit Range/Performance. So for P0343 I got the Camshaft Position Sensor for $70 and for P0321 got Crankshaft or Speed Position Sensor for $110 ( FYI, Crankshaft Position Sensor & Speed Sensor are the same ). Paid $160 to get both sensors replaced. I know both sensors are easy to replace but it was easier to pay..

I have a 1994 Saturn SL and ever since I bought it a few years ago it has been overheating in traffic but does just fine when I am driving without the stop and go. About a year ago 2 of the cylinders blew and I had to spend $700 to replace the now shot motor with a rebuilt one. Well the engine still heats up. I tried replacing the cooling sensor a few weeks ago and still no change. It really sucks because the only thing that keeps it from totally overheating is if I put the heater on full blast. And considering it's almost summer I really want to get this thing fixed. Using the A/C only makes it overheat worse, and will make my engine stop if I keep it running while stopped for a few minutes at a time like at a stop light.

I have a 2001 Econoline and the turn signals work in the morning but when the vehicle warms up they stop working. I have replaced the bulbs and the fuses. What I could try next.

I purchased a 2001 Jetta and it ran alright for a few days then all these problems started arising. The engine would not idle correctly and then a week later my EPC light started coming on. After all of that I have replaced the Throttle body ( Bosch) the MAF ( after market) and gas pedal ( after market). It ran fine for a day and then same issues. I had a mechanic relearn the throttle which had the Engine light go away for about a day. Now all the issues have came back. Here are the main problems.
1. Randomly lose throttle ( up hill, down hill, highway does not matter)
2. I randomly get stuck in park and cannot shift at all.
This is extremely troublesome since every time I lose throttle i have to put the car in park, shut her off and turn her back on to be able to drive. I keep getting the Throttle and MAF codes. I also checked on the recalled parts and they have already been replaced. I have read many reasons as to what would cause this but even the mechanic doesn't even know and I cant pay for him to check the electric. Also when driving if it is raining my car will not start or when it does it chugs. I was running through a puddle and after the water splashed the car basically would no longer run.

My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
