Golf IV / Jetta IV :: Cooling Fan Won't Turn On - Power Loss After Driving For About 20 To 30 Minutes?
Jun 14, 2014
I want to start by saying I'm new and don't really fully know how to search vortex, I'm sure there's probably a bunch of things about this. I have an 04.5 gli, my temp gauge reads 190 all of the time but according to vag com I'm running at about 220 some times higher. I've heard my fan kick in once in the year I've owned it. Also I get a decent amount of power loss after driving for about 20 to 30 minutes. Idk if that's related, but just hard wire the fan with a switch? I don't have a lot of money so I'm not really trying to play a guessing game replacing stuff.

Ok, so I was driving normal highway speeds and all of a sudden, I realize a major drop in power. I pull over and restart it and it changes nothing. Now when I floor it, it takes 20-30 seconds to get to 90K.
I checked the air filter... Nothing. Used a code reader... Nothing. Then I decided to pressure test the cylinders... Nothing, except now the check engine light is on.
The Ol Dub is still drivable, but it is extremely slow and rough at idle. I am thinking it might be a MAF or fuel filter.

I've been experiencing power loss at random times while driving, idling, With almost always flickering headlights on my mkiv 1.8t gti. Also on what always seems like the exact same spot on the freeway I'm losing all power to the wheels and it feels as if my plugs aren't firing for about 10 seconds Which causes me to bog down. At which point I down shift and play the throttle until my motor then begins running normally again.
I've semi recently replaced my battery and terminals, due to corroded terminals and worn out battery. Is is possible a ecu reset could solve this problem?
Also when the power surges during driving my traction control and hand-brake lights on the tachometer will flash and the car will beep three or four times (same as when the hand-brake on beep).

My 03 Golf ac is not working and i am looking for a wiring diagram/ troubleshooting chart. the cooling fans turn on low and I hear the engine surging like the compressor is trying to cycle but it is not.. When I jump the low pressure switch the fans go to high and no power to the compressor. I get a flash of power to the compressor but just a blip every ten seconds. I am trying to check continuity of the ac clutch but having a difficult time getting in there hot. I just bought the car and fixed light body damage on the right front but it was not even bad enough to hurt the washer bottle. Hard to believe the hit caused damage to the ac? AC seems to be charged with about 100 psi static pressure. Why are diagrams so hard to find?

Lately I've been hearing a constant click from what seems to be my chains side of the motor. Tensioners and chains were said to be done around 123k. After I've been driving it for a few minutes I hear the click. I thought it was the trans/ throw out berrying but when i push the clutch in and have it in gear i can still hear the click. It is not rapid like a tensioner like a tick tick tick, its like tick......tick......tick, could this be my top end of my block not receiving enough oil? I have a cracked oil pan, doesn't leak that often but i feel as if that is the source of the problem. Also I feel as if i lose power once i hit about 4300-4400 RPMs could that be because of low oil pressure?

So I have a 2001 VW Jetta Wolfsburg Edition, love the car. So here's my problem, whenever I am driving for more then 20-30 minutes my shifting between gears begins to become more and more rough, like whenever I shift from 2nd to 3rd, it directs me to first gear instead of 3rd and I have to kinda force it into 3rd. This only happens when I am driving for a long period of time, why this is happening? and sometimes when I put it in reverse I get a loud crunch noise but I get it into gear...

i have a 05 GTI 1.8T and recently started overheating while driving. for a few months it would overheat if i idled too long but now after driving for 5 minutes it overheats and also wont build any boost. i could hear a hissing sound after i shut the car and thats coming from the flange where the coolant temp sensor is, but is hissing where is mounts to the engine.
update- i replaced the o-ring on the flange, that got rid of the hissing. the no boost must have been due to the engine overheating, but it is still overheating i guess im gonna check the thermostat next.
update 2 - checked thermostat and it is good so I'm at a loss here.

I have a mk4 Jetta 1.8t. Problem started last night. After I drive for about 15-20 minutes the oil pressure warning light comes on. It doesn't feel any different and my oil is full. Could my pump be going bad? I hear a slight tick near the bottom of the engine on the passenger side. But the car idles fine and drives fine too.

This only happens once or twice a week. After driving the car for 20+ minutes and sitting in the driveway, it will start running hot. I'd say around 230 degrees and it will stay there until I start driving the car again. I made sure the fans work and I also checked the coolant level and both are fine. What could be causing this issue?

My AC has been cooling once start-up the engine and turn it on onward. After 20-30 mins of driving, cooling has been reduce and blowing seems reduced as well.
After arriving the destination, i check the engine bay and i notice the tube part going to AC valve expansion it frozen and covered by ice.

I have a '00 RAV4 I bought from my Mother. It was having loss of engine power and it would stall while driving and then turn off while driving. The car was taken to 4 mechanics, non could figure it out changed the sensor air fuel ....worked then did it again sent to the Toyota dealer changed the same part ....the problem seemed to be fixed....I've had for a couple of weeks and the problem came back...what I notice was a low idle, loss of power....then the car started stalling while driving, the rpm idle dropped to 0 and car shut down took to mechanic said the throttle body was dirty . They cleaned it they said that it fixed the problem ....2 weeks later it happens again to 2x .....I don't know what to do ...

Today i come here for a AC/Compressor trouble: The AC on my Jetta 2000 2.0 works very well, however it seems that the engine loses a lot of power when the AC is on (the acceleration becomes very slow), and at the moment of turn on the compressor, the engine revolutions down to 400 rpm for a couple of seconds (after back to normality, 800rpm on idle).
I know that the power loss on engine is "normal" with the AC, but in mi case, seems excessive, and the fuel consumption, when the AC is on is vey high too. I think that maybe the compressor is stuck, but I'm not sure about that.
As additional information, i scanned the engine codes an throws P0422 (related to oxygen sensor)

I bought a 2000 jetta gls vr6 5-speed. Only had the car about 4 weeks, already I am in, ball joints, struts, brakes, core leaks and my half shaft fell off at the transmission. Now, driveabilty issue.
Severe loss of power, sputtering bad. when i shift, the car revs a bit. installed new O2 sensor due to a rich code and a out of range code. Now the EPC light is on with an implausible brake switch signal. Replaced switch still comes back on. Still running like poop. Changed the plugs also about 1k back. I just ordered a MAF.

I have a 04.5 GLI 1.8t, performance mods include, cone filter on the end of my maf, silicone TIP, Forge splitter, 3in custom tbe and unitronics stage 2
I started noticing this problem on the day I got the car tuned, I hadn't noticed it before hand. I replaced the spark plugs and it worked a little, but it continues to do it.
The problem: When I get on it at WOT under full boost, around 2500 rpms, the car loses all torque, misfires spits and sputters throughout the rpm range until about 5300 rpms then it all of a sudden has torque and pulls great.
I don't have any boost leaks that I know of along with vaccum leaks. There is no flashing cel or misfire code for my coil packs. Can this be a faulty n75 valve? if so what could fix it?

My car has been throwing a code P2178
P2187 System Too Lean at Idle (Bank 1) DTC.
Checked the intake, checked maf, checked injectors.
Today after leaving show n go. Stopped at a gas station (never turned off the car) leaving the gas station the car was loosing power, I thought I was in 3rd instead of first. No, I was in 1st. Driving and car was sputtering and wasn't getting any power. After a few blocks it sounded like its gonna shut off. Pulled over to the side. Car died, doesn't wanna start again. Got spark, got fuel to the injectors, discoed the sensor to maf, still cranks but doesn't start. Got it towed to NY from NJ. Still no start. Few people said crankshaft sensor, starter, clogged cat or fuel filter. Car isn't throwing any codes now (probably cuz the motor didn't start) any clues on what it can be?

Started my car (02 with a 2.0) this morning and as I pulled away the EPC light came on and the car lost power, almost stalling. I kept on going, and then the check engine light came on.
Got to a stop sign and it died on me. Battery light came on at this time as well. Started back up no problem but idled rough and kept dying. Just kept restarting and moving bit by bit until I could get home. EPC and check engine stayed on through all of this.
I also noticed that it would buck like crazy around 3000 rpm and not increase past that point. What could be going on here? I'm going to pull codes when I get home.

I have a new to me 2012 R... I have a loss of power or almost like a traction control cut in on right and left turns from a stop. I cannot find anything in my searches. But I am not totally sure what to search on. It is not on rolling turns just from a stop. All tire pressures are consistent. No ice or water.

I drove my car to work today and no problems. Tonight my wife and I took the car out to go to dinner and intermitantly there and back my car is hesitating as we drive along. I thought it was odd at first then my wife asked if I was kidding around. I told her its not me.
It's as if the car is driving then all of a sudden its like a loss of power or as if the limiter kicks in and starved the engine of gas and then a second later it jerks back to life and keeps going.
If it does this tomorrow its going to the dealer. It is not throwing any warning lights and I have 3/4 tank of gas so its not that.

I have a 2005 jetta 2.0 Once it gets under half a tank I lose power, it acts like it's running out of gas. It only does it in warmer weather (this started in march when we took it to Florida, once it got back in the cold weather it didn't do it again until 2 days ago when it was in the 70's). I took it to he mechanic I've used since I got the car (he works exclusively on vw and audis). It didn't do it to him in the two weeks he had it, he couldn't find anything wrong that would cause the issue.
He did do a complete tune up, replaced both of my fans and coolant. I ended up replacing the coolant temp sensor myself since that decided to go bad after I got it back. It lost power after getting the car back again warm weather and just under half a tank of gas. Prior to the Florida trip the water pump, timing belt and starter were replaced. I had my fuel pump replaced in 2014. It is an automatic with 157k miles on it.

The past couple days when driving to school in the morning i've been noticing that my car starts to rattle and struggles to accelerate once I pull out of my driveway. Once i get to the next stop sign to take off the car runs fine like nothing ever happened. My check engine light doesn't come on though. I usually let the car sit for about 30 seconds to a minute before i start to move the car. Mods I have are Unitronic stage 2, Forge 007p DV with yellow spring, and 3" downpipe.

just picked up this 99 Jetta with about 150,000 miles and while driving all of a sudden i had extreme power loss, shaking and shuddering, and the engine light came on. My code reader found multiple random misfires cylinder 1 and 4 codes P0300, P0301, and P0304.
