Passat (B7) :: Shudder Or Lag Usually At About 25 Mph / 1500 Rpm
Mar 20, 2012
I have had a 2012 SEL Premium TDI for a little over three weeks. Starting last week, I've noticed with a cold engine, during the first few minutes I'm driving, usually at about 25mph, 1500rpm, barely pressing the gas, I feel the car kind of shudder or lag, almost like a manual transmission stall (hence my title since it is a manumatic) and the rpms will drop/jump a little bit. This has only started recently and once I've driven a few miles and the engine/tranny gets warmed up it's fine. No CEL. It did not do this at all during the first couple weeks of ownership. The temps have come up about 20-30 degrees in the last week, could this be related? Does the car just need to learn how to deal with warmer, more humid air??? If that was the case, why only during the first few minutes of driving?

I've got a 12 FX4 SC 6.5' w/Ecoboost. After 1K miles I began to develop a shudder/shake in the tranny-driveshaft passing through 1500 rpm. 4 dealers, 6 overnights and 2 escalations, I finally am told there is a design problem in the pre Jan 12 trucks. Fixed with frame mod to manufacturing process after Jan, but no solution for current owners with the problem. I replaced my 07 FX4 SC with this truck and loved it for the first 1K miles. Now I hate driving it, especially in traffic (lots of cycles through 1500 rpm).

My wife's 03 B5.5 with 130K has started to shudder really bad during all shifts, up or down.
The trans has never been serviced since that is what we were advised upon original purchase.
I've heard of valve body replacement and/or a service including a power flush. filter and screen cleaning might do the trick.

So, a couple days ago, my car started to shudder a little bit and the check engine came on and started flashing. I pulled over and restarted it and it came back but then it went away. I tried to take it to Auto Zone the other day but for some reason my car wont communicate with their diagnostic computer. I read that its probably the coil packs but I want to be sure before I spend the money. I changed the spark plugs which were in desperate need of being replaced and it went away for a day and the CEL went off but it just came back today. I'm gonna try a different auto parts stores diagnostic computer before I give up on checking that.

Every once in a while, while idling at a light/stop-sign/etc, I get a shudder in the engine... usually all is smooth as silk, and then its like some fat kid just jumped inside the engine compartment (I'm exaggerating) ok, a very small fat kid its like weight shifted somewhere and you feel the ripple from it.
I did find this old thread [URL] .... but doesn't look like much came of it. I don't really suspect its a big problem, but definitely nothing I've experienced since 4-5 VWs ago, when I had a throttle that would race up (but the engine revs don't seem to be changing during this).
Car is in the shop for 10k today anyway, so I figured I'd have them take a quick check. (gotta see if they can do anything for the lackluster AC too).

Have driven Hondas for 25+ years and used to their appliance like Smoothness and reliability. Yesterday bought my first VW ever, the last 2010 Passat ( a sedan) in my dealer's inventory.
I immediately noticed that while coming to a stop for the final few seconds there is a jerkiness and shudder that I feel. Feels like the way a manual transmission car feels when you forgot to depress the clutch and you're stopping. Once I come to a complete stop all is fine again.
Is it "normal" for the passat or vw in general?

I was driving my car when suddenly I felt a huge shudder and my engine light flashed on. I turned a corner to head into a parking lot and as I accelerated my car seemed to be jerking like it was cutting out. I parked and tried revving it and it sounds all deep and gurgly not smooth. What could be wrong and is it safe to drive the 5 miles back to my house.

In the first two years of ownership of my Passat, when I would turn the car on during cold days, the rpms would stay at 1500 for a quick 20 seconds until the car got a bit warm and then would drop down to about 800. Recently, when I turn the car on cold days, the rpms drop directly to 900 and below.

I had recently purchased a 2003 golf gti AUTOMATIC (with optional shifter) with a 1.8 turbo 4 cylinder engine. The vehicle has 139,000 miles on it. Before purchasing, I had a mechanic come out and look at the vehicle for a pre-purchase inspection, and ran the code P0303 (cylinder 3 misfire) which without test driving, told me that is what caused the shift shudder I noticed when I had test driven it a previous day. He told me the coil packs were in good condition by looking at the top of them, and told me if I replace the spark plugs, the issue should go away.
I feel it is important to mention that he had also run codes on the transmission and nothing came up. Taking it home, this morning I had replaced the spark plugs and driven it for about an hour both regularly and aggressively to test it. The problem is still there, and I was really hoping that there is a solution to this problem, because everything else on the car is beautiful, while being my dream car, I just want it to work as well as I know it can. To be more descriptive, when shifting to 3rd the whole car feels basically like it is tripping over itself before successfully shifting.

I have a 2000 1.8t and I was on my way home from work, sitting at a traffic light and my rpms went up to 1200-1500 and then my check engine light came on.

So I bought my R with 9000 miles on it, and I noticed a little bit of shudder when braking. For some reason it is starting to get a little worse.....and I haven't been bagging on it. Really, warped rotors....at 9k.

My engine tends to shudder a whole lot when starting (sometimes) I also hear an audible clunk or Thunk sometimes when the normal engine simply starts as well as when accelerating, Decelerating, braking, and accelerating on reverse. I know you may think, axles, but I recently replaced them twice because the first pair made my ABS turn on so I'm returning those (bad brand called "EMPI"), and these second ones seem to be working great (aftermarket SurTrak, the dealer has the original ones for about $600 each WAY too expensive) but I started noticing the clunk after 2 days.
Notice: it is one single clunk not a clack clack clack when turning, no. It is only heard when accelerating, decelerating, braking, and accelerating on reverse; one single clunk. I've been searching a lot and narrowed down the possibilities to motor/Trans. Mounts. Notice: I've recently changed struts, springs, stabilizer bar, wheel bearings hubs, as well as the front axle shafts.
I have a 2004 with 175,200 miles on it by the way!

About 20000 miles on it, had dealer service a couple weeks ago. Going to a friends this evening. Stopped at an intersection when accelerating again, there was a shudder for a second, different than the normal motor start up. Then I noticed the CEL light and the Hybrid system light were on. No place to pull off the road so continued on about 1/2 mile to the friends condo and pulling in the parking lot it seemed like the engine was in safe mode, reduced power, so parked it there and got a ride home.

Whenever I stop my T-Reg (like at a light, etc.) I feel a rumble and can see the RPMs take a quick dip below where the car normally idles (this happens just before the car has fully stopped). Pretty much I feel the rumble for about second and at the same time can see the RPMS rapidly dip. When the car has made its full stop the RPMs come back up and the car idles normally. Sometimes the dip is more drastic than others, but you can definitely feel a rumble or shudder. It almost feels like the rumble associated with a car getting ready to stall; except it never stalls. What is causing this?

How many motor mounts the gen 2 prius has? My ICE seems to shudder quite a bit when it fires up. I've checked the one underneath the engine and it looks good. So say there is 3 mounts and i could only replace 1 of them which on does the most dampening?

I got a phaeton v8, I feel a big shudder in the whole car while I have an amount of pressure on the brakes. for example: when approaching a red traffic light soft braking: no shudder, half braking: shudder and when hard braking the shudder is gone again. what could be the problem?

I have a 2002 Santa Fe 6cyl automatic GLS w/ 170k on it - great car - never a problem until about 20k miles ago, I started experiencing a shudder (like driving over a washboarded road) at 38-42 mph. If I accelerate quickly through this mph range (from 3rd to 4th gear), I can avoid it. Similarly, if I downshift back into 3rd, accelerate through and then upshift to 4th again at about 45mph, I can avoid it. It happens at a much lesser extent around 55-60mph. It has been to a reputable transmission shop that doesn't think its a tranny issue. Its been 4 days at a good mechanic and they can't find the problem. Its not throwing any codes and no other part of the vehicle seems to be affected. It has new tires/alignment less than 5k ago. I have suggested several things (ignition coil, torque converter, throttle control sensors) and they have checked these and more and don't find the problem.

2006 Prius ...
Symptoms: The shudder feels like going over a "washboard" dirt road. It mimics the normal "cough / hesitation" that occasionally happens when the MG2 switches to the ICE while accelerating, or vice versa at a stop light. However, unlike the normal switching, this is continuous. It ONLY happens when accelerating; as soon as I lift my foot from the gas, the shudder quits. Although it is worse in stop-and-go, it is also noticeable on a clear freeway. It is worse with a cold engine, but continues from speeds of 10 mph all the way up to 80 mph (and probably higher.) The shudder is slower at lower speeds, and faster at higher speeds. It is most dramatic when making a left turn from a dead stop - the whole vehicle shakes. Weather conditions vary, but usually it happens on dry, paved roads, anywhere from 30-degrees to 75-degrees (F).
Frequency: first noticed a few months ago, gradually becoming more frequent. Now, it is almost every time the car is started. (Sometimes it accelerates without any problem at all.)
Diagnostics: The "Check Engine" light has been on for about 5 years (dealerships couldn't find anything wrong and it turned out to be the MG1 battery.) But when this new shuddering happens, the "Check Engine" light blinks continuously until the shuddering quits (i.e. let off the gas or brake.) There are no other indicator lights on (no triangle of death). And the diagnostics mode tells me nothing.
Other Info: The MG2 battery has not been replaced in the entire life of the vehicle. The MG1 battery was replaced, however, about 2 years ago. Regular oil changes have been kept up, along with air filter replacements, brake pad replacements, tire rotations, and all the other standard maintenance. It has had one owner, and is at 255,000 miles. MPG is currently at about 44.4 and has not changed since this problem started.

I had the transmission replaced last fall under warranty. the VW rebuilt unit was 09L 300 035 PX. When unit was replaced the dealer used G 060 162 A2 as the fluid. Was that the right oil? Shouldn't they have used the upgraded G 055162 A2 and the new reflash? The shudder has started to return and I am off of warranty.
