Golf IV R32 :: Noticeable Bogging As The Car Jerks Up And Down
Aug 6, 2011
I did some Autocross today and it was fun as always, but my launches had some serious issues. I seem to bog down no matter what RPM I launch at. I did not go particularly high, but I launched from 3500 to 4500. When drag racing, I was launching around 5000. I did not think that was correct for launching for autocross, but who knows. I know that the video is not that great, but the boging is very noticeable as the car jerks up and down. It just loses momentum and RPMs drop. BTW, I have a VF Stg II, stock clutch and ESP was off. Even with the issues, my best time was near the top. [URL].................

My car is stored outside rather than in a garage in winter. I do notice bogging or "gargled" acceleration maybe 4/10 on occasional days and sometimes the engine light will come once this happens and then other times it doesn't come on when it occurs. Engine light usually comes on rarely but when it does, it's when the bogging is really bad.
Question is what would be the most cost effective way to solve or find out what the issue is? And/ or, what would you think the underlying issue would be for starters? Also, does my year car have a MAF sensor? BTW the cabin filter and air filter were just changed a few months ago but unsure if this would include the shop cleaning the MAF if I do in fact have one.

I have a 2001 vw jetta 2.0 and I was accelerating on the interstate the other day and the car just started bogging down and now the car only accelerates slowly at partial throttle any more and it makes a loud intake noise and bogs down also the car idles bad and even at partial throttle the car struggles to get above 3k rpm, I scan for codes and got MAF, O2 sensor before the cat and camshaft position sensor, I replaced the camshaft position sensor and car still runs like crap, what is the problem??

Whenever I completely engage the clutch after shifting into 5th, there car bogs for a second if I give immediate throttle after shifting. It doesn't happen if I wait a second or when driving in fifth gear.

To start I drive a mliv 1.8t jetta. The car has a stage II custom tune, a turbo back exhaust straight piped, and a splitter valve. The valve cover gasket, spark plugs and coil packs, rear o2 sensor (with a 42dd spacer as well) were all changed recently to try and stop my problems from reoccurring. Also the MAF sensor was cleaned too, but was not very dirty. The problem tends to cease when I delete the codes and it has to relearn the fuel mapping. When the check engine light comes back on, the problems re occur. The code thrown is catalytic converter below threshold, but i have no cats. What happens with my car is, when the car is fully warmed, the car has a rough idle, to where it sounds like a heavy duty diesel truck when idling, the car will shake from the vibrations, when i go to start moving, the car bogs down to where it feels like it will stall, but it will buck and shoot off. Also when driving the car randomly bogs down, but then will shoot off will power! Sometimes at idle when its bad, if i tap the gas, the car will back fire very loudly.

I'm having with the first startup in the morning. The car turns over fine, but when I accelerate there is a noticeable hesitation. This was only occurring for the first 20 seconds, when I accelerate out of my driveway. Now, it has gotten progressively worse. Still not stalling or anything like that, but it has become more pronounced. I have an APR stage 1+ with a Carbonio intake. Others mention they were experiencing a similar situation. I have tried idling before shutting the car off as well as letting the car sit for 30 seconds after I start her up. Im wondering if I disconnect the battery and allow the ECU to reset might work.

So most noticeable is when i go into reverse. Initially it makes a loud clunking noise until the car begins moving then it stops ( sounds to come from right under the middle of the car, middle/front). Nothing like this in 1st from a slow start. But Another different noise between first and second when accelerating hard.
As I go to shift from first to second there's another louder clunk in between shifts. It almost sounds as if my seat wasn't bolted down tight and was moving. But definitely coming from under the car again, same spot...I just had a 42DD downpipe installed.

I know- another noise diagnosis thread but I'm very confused and worried about these noises coming from the front of my car. It's a creaking noise that's most noticeable when I engaged the brakes. I first assumed it was an engine mount- hopefully it is. I'm replacing my vf dogbone bushings before Tod. But this doesn't sound like rubber creaking, by metal. Like the chassis by the strut mounts. I hope it's nothing regarding the v3's. Maybe it's something with the brakes? I also hear I slightly when going over speed bumps. Again, I doesn't sound like the rubbery rear sway creaking. What could be the cause? I'm replacing the pads and fluid before Tod as well..

So I took my car in for the 10k service. I also wanted them to check out some squeaking my car was making that was noticeable when coming to a stop in say a parking garage or drive thru, and also the rattling I'm getting from the door panels. When I go to pick up my car, they said that everything was because of my exhaust and that they couldn't do anything about it. They also drove my car over 20 miles and that was the best answer they could come up with? Is it just me or does it seem like they were just joyriding my car? They couldn't even turn off the "service now" reminder. I really dont see how the rattling can be caused by my exhaust when I've brought it in for the same reason before I had the exhaust. What I should do? I mean the door panels rattle when coasting in neutral even, not just when I'm accelerating.
Also have a little squeal when turn the car off? Sounds like a belt to me but not sure.

So, the R is my first stick car and I've only been driving stick for 5-6 months now. I know that smoothness comes with time. I feel pretty comfortable with my skills overall (still have some issue with hill starts and smooth starts in general). Wen I don't know what I'm doing wrong when it comes to upshifting from 1st to 2nd. All other shifts are smooth.
When I try to shift normally, the car jerks. So, I tried releasing the clutch slower, this gets rid of the jerk but it bogs the engine. I've tried various things like getting back on the gas a little sooner, or pausing/slowing down the clutch release through the engagement point but I just can't seem to figure out what works and what doesn't. Is this just an issue of a larger gear ratio gap, rev hang, or what?

Yesterday I jump on the freeway, shift to 5th and the whole car jerks. Happened again later that night. After that I was more focused when shifting to 5th and it hasn't done it since. Could it be this B&M short shifter that the last owner installed? I also noticed since day one that when the car is cold it doesn't like going into first sometimes, meaning I can't throw it all the way to the left and then up to get to first. It's more like a little to the left and then up but when the car is warmed up I can throw it all the way to the left.

My 1.8T jerks really bad going into boost and I have no power then it tries to boost and wont. It goes into what feels like limp mode and then no power acceleration is slow. Scanned it and got map over boost or high boost ...
Here are my mods:
APR stage
2 Cai
3' test pipe to 2.5' magna flow
R8 coils
Forge 008 running yellow spring
Eurojet smic

Car is stock and I seem to be getting a lot of jerking when I am on and off of the throttle peddle. It feels like a combination of sloppy motor mounts and a throttle response issue. What may be causing this? I am willing to bet that the motor mounts are partly to blame but it seems that there is more going on here.

Whenever I brake hard the steering wheel jerks to the right and the car follows. And it'll stay to the right until I got about third gear or if I shake the wheel back and forth. Not sure what it is. What could cause this? 01 jetta wolfsburg.....

I am at a complete loss as to what could be wrong with my 2002 VW Gold Cabrio GLX automatic transmission. In the last month the car has been to 3 different mechanics & none of them could solve this problem. The basic scenario: The car starts up fine. The engine will run & everything works fine (AC, radio lights etc).
If I put the car in Drive or reverse...it will idle & move. However, the moment I touch the gas pedal, whether in reverse or Drive, the car jerks & dies. If I put it in park & try to start it up again, the engine will turn over & the car will start, but the moment I touch that gas pedal again, same thing, jerks & dies.
Things that have been replaced so far: ignition coil, fuel pump, the catalytic converter has been removed. spark plugs replaced. Now they are saying that the problem is electrical & are working with the fuzes & wires. The car ran fine for 3+ years & I've had no problem with it.
Yesterday the mechanic called me & said the car was ready for pick-up. I go over there, pay him, I reverse out of the driveway & the minute I press the gas, it jerks & dies. Is this problem really electrical? Or is this third mechanic also grasping at straws?

So I've been dealing with this for a little while now and it's starting to really irritate me. With my 850, when cold, it drives awesome- perfect engagement, pressure, etc. When hot, I'm noticing that even with the pedal to the floor while in gear, I might get a few 'jerks' until it frees up. Also engaging while hot (in traffic) can sometimes cause rapid 'jerks' which leads to stalling, the pedal engagement is all over the place and you really have to know how to drive the car, just to get it right.
Now I've bled the line about 4 times now in the last three years and it seems to improve slightly (maybe placebo effect), but I'm not looking into it maybe being the grease on the input shaft? I know we greased the throwout bearing and input shaft, but it was a very light coating since I was nervous about getting grease on a $2400 clutch.

It is difficult to explain (and google) but my 1.4 16V Golf 4 does this sometimes: while driving at a steady speed car jerks for a moment and revs drop quite much, a moment later it is fine. It feels like I had stepped on the brakes, but when I actually try that the revs won't drop as much. Like my engine seizes up for a fraction of a second but there is no noise. It has done that actually for 3 years, but it was really rare, about twice a year, but now I have had those jerks three days in a row.

VWVortex, so I've had some issues with my MK4 recently (go figure). It started with steering wheel getting intermittent and random jerks to the right after driving for about 20 minutes on the highway at any speed any gear but only at around 1/6 throttle. I needed to do front end maintenance anyway, so I replaced both complete LCA's with ECS Tuning's ply ones, went stage 2 BFI engine mounts, stage 2 BFI dogbone mount, both ball joints, both tie rods ends, both axles, and an alignment.
Now I'm getting a shimmy in the steering wheel starting at ~80mph. I know my wheels are slightly bent and are being replaced in the summer when the weather is warmer, but it wasn't doing this same shimmy prior to all this. Just the jerking. Could it be they messed up on the alignment? Its really getting on my nerves considering I've dumped a lot of money trying to fix this problem just to have something else pop up.

I have a 2001 vr6 Jetta automatic transmission. When I shift my car from park into to reverse or drive the whole car jerks as if it's banging into gears. But while driving it drives normal. When I stop and accelerate I feel the same jerking you would say.
