Golf IV / Jetta IV :: When Turn The Key Engine Almost Starts For A Split Second And Then Shuts Off
May 31, 2014
When I go to turn my car on, I have to give it 3 or 4 tries. The try before it actually turns on goes like this: turn key, engine sounds like it wants to turn, almost starts for a split second, and then shuts off. After this I can usually turn it on.
Usually the rpm's would be around 1.3k on a cold start, but when I finally get it to start it automatically dips below 1k. Then when I go to drive it, it feels like it wants to shut off on that first throttle push. It started with just an issue in cold weather, but has gotten progressively worse. Battery is only a few months old.

When I parked this car 2 months ago it ran fine. Went to start it up and it starts and shuts down. I do not think its the security issue. Both keys do the same thing.
Battery is new recently. There are no MIL lights working on the dash except the battery light. The actual dash lights will not come on. Doors will unlock but not lock. My VAG tester will not communicate with the ECU.
I have checked all of the fuses multiple times. I can hear the fuel pump prime up when the key is turned on. It appears that there is an electrical issue. I took the connections off of the ecu, waited a bit, check for cleanliness and reinstalled also.

Looking for some hint regarding V6 AUE ? Regardless if engine is warm or cold, sometimes happens to me that during driving, while slowing down and pressing on clutch pedal, revs just drop down to 0 and engine shuts down (vehicle still moving). This usually happens while changing gears from 3rd to 2nd on low speeds in city, or while slowing down to full stop in 2nd gear and pressing clutch pedal.
While this happens, I quickly switch off the ignition and start the engine again, which is tricky and potentially dangerous, since vehicle is still moving but my power steering and brakes are not functioning because of stopped engine.
Some relevant info...I have K&N cone air filter intake and ECU is remapped by BTS Racing (German tuning house).
Car is running and pulling normally. In all other regimes of driving, there are no issues or whatsoever.

2001 Jetta 1.8t... Recently made a change in the engine head because in broke the timing belt and had to do valves etc., the car was without power(battery disconnected almost a month), now when it start, a light(symbol orange)comes in the cluster and the engine shuts off, what is causing this problem.

So I just bought a 2000 MK4 Jetta for a $1000, its been ok, replaced the breaks, rear calipers, swapped in new headlight socket, swapped in amber tails, new plug wires, new drive belt, water pump/ timing belt all new.
Car has 173,xxx and i drive in pretty bad traffic daily, there are times when i am going to accelerate and between 2-3k RPM it feels like the clutch disengages then re-engages for a split second. then continues to drive normal, happens 2nd, 3rd, and 4th. Is this the clutch slipping? will it be fixed if i were to order a new clutch kit? I am on a budget and do all my own work, so i can't afford to buy a new clutch kit and have this not fix the problem.
Also, the car gets a little wiley on the free way, feels like its the struts, but the steering wheel vibrates a bit, i just found out the PO had different rims on the car before. So the tires might need to be balanced. I JUST Ordered new Racelands hopefully to stop the creaking/bounciness of the suspension. How to get this steering in check.

This is what its doing... Im starting to feel lost about whats wrong. I start it up and everything is fine. With in about 10 minutes it starts to bubble and spit out a little water then shuts its self off. And the gauge on the dash never reads above 190. And the fans don't come on unless i turn the ac on. And the ac still blows cold. The lower hose stays cold. I just replaced the thermostat and the water pump. But it changed nothing. Im thinking maybe its clogged somewhere. Maybe in the heater core or the radiator.

-6 degrees this morning. Drive to class fine, come out afterwards to my remote being dead. I popped off the cover to the door handle and unlock the car....alarm goes off. Try to start the car and MFD says key not recognized...it starts but shuts off after a second. How to separate the key without tools? I can't seem to pull it apart.by hand like the old Mk4s.

Have problem with Golf IV 1998 1.6 74KW.
Ignition is troublesome, takes few seconds to start. RPM stays still at 800 idle but when pressing down gas pedal it takes few seconds to accelerate to 2000+. While driving engine starts to sputter under 1500-2000, happens after every gear shift. 2000+ does not sputter much but car still feels very weak.
Everything works fine at the morning or several hours after last ride. Problem starts when car hasn't run in 15min - ~1hour, problem seems to go away only in several hours.

I searched but couldn't immediately find anything about this particular line. I've been struggling with a rough idle for the past couple weeks, throwing codes that I'm running to lean all the time. I cleaned the throttle body and MAF, and was in the process of replacing the MAF and noticed a small hose fitting behind the MAF but before the throttle body was pretty much split in half. I don't know what it's for and I'm replacing it regardless, but could this be the source of my problem?

How do you warm up? I turn it on and it might start the engine for a few seconds then shut off... How do I know it's ready and warm?

I have a 2002 GTI 1.8T with the AWP engine and tiptronic. There is a fuse in the picture below that blows as soon as the car is started. It is located next to the brake booster on the firewall. It does not blow when the ignition is turned on, just when the engine actually starts. I'm not throwing a check engine light, pulling a scanner code or noticing any of my electronics not working. I took a 20 AMP fuse out and replaced with another 20.....and have since blown 5 of them trying to diagnose the problem.

Since day one I've had an issue with the exhaust leaking on my car, right at the flex pipe before the cat. I have replaced it at least 5 times in the last year. Every 2 moths or so it tears the flexpipe right in half, like it's literally in 2 pieces when I take it out. So, I thought that maybe the factory dogbone mount was old and weak, causing the engine to move around more, therefore tearing the flexpipe apart, so I got an new dogbone with poly bushings to combat that. It did reduce engine movement, but the exhaust kept breaking at the same spot. Then I thought that the metal was weak from it being welded so many times, so I got a new downpipe with the cat on ebay for like 150 CAN, and put a new gasket on, and now it still leaks...
Only thing though, is that this time on cold starts (as it is winter, so around -25 celcius) its really REALLY loud, like the exhaust sheared off right after the cat. However, after a few hours of driving it seems to get quieter at idle, but if you give it a little gas, it is quite audible. Also I can see exhaust fumes coming out my engine bay on said cold starts, however if I get down to ground level, I can hear it plain as day right where the pinch clamp is that connects to the catback part.
So, my theory is that, cause the bands on the clamp rusted out so my dad just put those u-bolt muffler clamps on there, which I can see an opening in the clamp, even if they're tight, until the exhaust gets hot and expands, kinda making the seal tighter but not air tight like it should. So maybe that clamp isn't doing it's job anymore and I just need a new one. OR it could be that that stupid flex pipe is broken again or that the bolts holding it to the manifold aren't tight, which that can't be cause i got them pretty snug on there. I'll have to take a look underneath again, see If I see any carbon on the exhaust, which would mean a leak, but I checked a few weeks ago and it was shiny metal, no signs of any leaks.
Car is an 04 golf with the 2.0 engine code BEV if that makes any difference. I double checked and NONE of the hangers are broken, and it's held in the right spot as it should, there looks to be no force exerted on the flexpipe at all when installed in the car, so I'm really confused.

2001 vw cabrio 2.0 .. The car starts and stalls BUT only if you give it gas. I replaced the throttle body and did the throttle body alignment using vas-pc , no problems at idle but as soon as i give i gas it dies, and it seems to die quicker at higher temperatures. When it dies i get codes P0121 and P1570 i clear the code , do the alignment , and same thing happens over again. I also replaced distributor , crank sensor, maf sensor , spark plugs, wires , rotor, tried different pcm reprogrammed, no vacuum leaks, the only thing i can think of now is the ecm relay? but its missing so is it using the fuel pump relay ?

A couple of months ago my daughter's Sebring engine began shutting off immediately after starting. We brought the car to my usually reliable mechanic. They couldn't find anything wrong. The problem became more frequent (every 2 to 3 starts) and we brought it back to my mechanic who determined it was the car's computer system. $1700 later the car is ready to be picked up, my daughter gets it after the shop is closed, and it wouldn't start! She left it there, got a ride, and, one week later the Sebring is still at the mechanic's. They told us it starts every time for them and they don't see any problem. After researching on the Internet I thought it might have something to do with the immobilizer but they told me that tested fine. I'm at a loss over what to do.

I just passed 3k miles on the OD. Lately, when I'm driving, I'll randomly feel the engine lose power for a split second. It just cuts out and then comes right back. Sometimes it's fairly quick, others it's very noticeable. I buy fuel from good gas stations, and the dealership couldn't find anything and also said they'd never heard of this issue.

I've had the car for almost 5k miles, no issues. Only performance part on the car is a USP 3" catless down pipe with an O2 spacer. Car performed fine with it. Today I got an APR stage 1 93 octane tune. A few hours into the tune on my way home from work, I went to change lanes and the car hit some type of a wall with the RPMs. At around 3200 RPMs, the car felt like it went into limp mode. Did not let me pass 3200 RPMs. I got off the highway and had to keep the RPMs up because the car died at lights. Pulled into my driveway, plugged in my VCDS and there are absolutely no codes coming up. Nothing. But starting the car the car cranks and I have to give it gas for it I barely start.

I have a '92 Ranger with a 2.3 liter engine. She starts and runs a couple of seconds and shuts down. I'm thinking maybe a fuel pump is not putting out thepressure needed. Gotta go to work tomorrow and gotta get the truck running today.

I recently removed my timing cover due to a coolant leak and found the cover was cracked. I had it welded and reinstalled but i did not remove the crank sensor from the cover while it was being welded. Now the engine starts but shuts right back down. Do the welding may have damaged the sensor and giving me this condition? 1997 4.2 ....

1999 Jetta 2.0l Engine Will Not Turn Over. The Battery Is Not That Old. Lights,radio Work. Oddly Enough The Trunk Will Not Open. It Acts As If A Fuse Is Blown And Shut Ignition Down. Windows won't go up or down. and my trunk stays on.

So Ive been having really annoying electrical issues with my Jetta. Everything works fine when driving, but sometimes when I turn it off after driving for about 20 min, the car electronics will not turn off and the engine will continue to run for about 7 seconds with the key out of the ignition and then sputter to a stop. The electronics do not turn off after the engine has stopped. I ripped apart the interior to look at relays and the ignition switch. They all look fine and they look like they are grounding fine. Do you think it might just be a bad ignition switch?
