Passat (B5) :: Software Upgradation Caused The Car To Hesitate And Stutter
Jun 5, 2006
When my car was brand new, in 2004, I had to take it in for its Tiptronic software to be updated. Apparently there was a Tech Service Bulletin on the 2004 V6 Passats where this faulty software caused the car to hesitate and stutter between 1st and 2nd. At the time, the problem was fixed right away at my dealership.
Now my car has 40,000 miles, and has been flawless. I took it in for the 40,000 mile service, and my car came back from being serviced with several problems mostly minor--the AM radio is suddenly static-y, the tires were all underinflated by 18 psi's. But a more serious problem is that the hesitation and stutter that I detected when the car was new 2 years ago is back! I can't believe I brought a perfectly working car in for 40,000 mile checkup, and now have these issues.

I am trying to get to upgrade to 6x9 speakers in the rear, but I can't seem to remove the back cover. It seems like I will need to remove the rear seats.
My car is a 2013 Avalon XLE.

My wife was driving this morning and she said that the car engine started to hesitate and shake a lot, engine light came on, started to bling. Called road assistance and they did a great work towing the car in less than half hour. Also noticed a rotten egg smell from the exhaust or engine.

My 2006 F350 is starting to heat up on me while at lights and parked while idling. I am going to do a reverse flush with Restore and Restore Plus as per Nylyons guide.
I also plan to switch out the oil cooler and upgrade the EGR.

I drive a 99 1.8t Passat with 90,xxx miles. Yesterday I felt the car hesitate/jerk a little when it's accelerated to 35-40 miles per hour. I've had this problem in my past and it was a cylinder misfire. I would bring it to the repair shop.
My question is: Can my car last about 1.5 weeks? My work is 20 mins away. I can definitely avoid the freeway.

I'm trying to fix a B5 1.8t Passat, it is usually a pretty quick car but recently it has had an issue where it "stutters" when accelerating. Meaning, if you put your foot down, it doesn't "take off" right away (you can't get the wheels to squeal) (not that I would try to do that normally). I know how the car used to feel, so it's not turbo lag or the ABS kicking in. It seems to behave normally after the initial stutter, it's most noticeable in 1st gear. I replaced the gas and air filters for fun, but no dice. No codes on VCDS shareware.
I can think of a few theories based on searches, but am not sure how to proceed;
- Plugged cat: expensive, not sure how to diagnose positively to avoid throwing money.
- Turbo issue? Wanted to hook up a gauge to see if the turbo is boosting correctly. Need to find a place to plug in.
- Clutch? Unlikely as the RPMs don't jump, and in third it doesn't slip. The acceleration makes it feel like something is slipping though
- ABS misbehaving? Light isn't showing up though.

2005 2.OT ... Our car showed an engine light last night and when doing heavy acceleration, starts to pull or hesitate. Do not occurs when accelerating slowly, all day at dealer and they said that might be cam wear or some pressure pump. They are taking the engine covers to find out what is the issue. Cam repair and oil change. It drives smoother and no longer hard down shifting....

I have a 00 Passat GLS.
When i accelerate, whether it's hot/cold/wet/dry outside, the car almost stalls. I have not had it stall yet, usually out of pure fear, i drop the pedal to the floor, and i catches up. I have had this happen at very inopportune times, like joining traffic. The car does a sort of stutter step.
I know little about new cars, but i feel like the fuel or air aren't making it through nicely.

B5.5 2001. When I am giving her gas you feel her stutter. But its not like a misfire stutter. Its more like a lose of power. Its almost like shes switching from boast to naturally aspirated. These stutters can also last a few seconds at a time. Where to start looking?

I have an 07 6speed MT w/ 82K on the clock. Today it was snowing on the ride home and I noticed a few occasions where the car felt like it was bucking for just a split second. No warning lights came on at any time. The RPMs and speed never changed when it bucked. I was driving between 35 - 55 MPH when it was occurring in 3rd, 4th or 5th gear. No correlation to accelerating, decelerating, or coasting on highway that I could figure out.
Given that the snow was covering even the treated road surfaces, I suspected it might be connected to the ESP, so I turned it off for a while. Still happened.
I didn't notice any abnormal engine noises and it was fine on my ride to work in dry conditions earlier in the day.
I haven't had any work done on it recently and I am getting the 80K service done next week. It has no engine mods done at all. All stock.
Could it have been the tires slipping on wet spots? But happening so quickly the traction light never came on? Or should I look for other issues in the engine?

I purchased a 2014 3.6 SEL from a non VW dealer. They may have put regular gas in the car, I feel like it runs weird, feel a delayed throttle response and a little stutter before acceleration? or is it just me?

Our 2001 Passat wagon 4cyl turbo automatic has a random idle stutter. When sitting at a stop light the RPM's quickly drop and then regain idle. It happens at random times and only when idling after the engine has warmed up. It doesn't seem to matter if its in drive or park. What sensor could be failing or a possible cause? Over the past year the problem has increased from almost never to a few times at every stop light. My OBDII reader shows no codes. Car has 105K miles and I cleaned the throttle body.

2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?

I had the transmission filter and fluid changed at the local VW dealership had some issues with that but they straightened that out and its been fine for a while well then about 2 or 3 weeks ago i was trying to mess with an audi and hit the gas (has the 6 speed auto tranny) and the car kinda stuttered and the check engine light flashed probably 4 or 5 times then went off, it did that a few times after that then my wife was driving it and it did that stutter again and the light stayed on, the code said misfire on cylinder 2..
So I replaced the plugs today and it did fine at first but when i got to about 55-60 and went to speed up and it started to miss pretty bad then steadied out and sped up. no check engine light or anything but it was missing.

2009 Passat 2.0 TSI. Purchased new in Nov. 2009. The car is 2 years and 3 months old. It has 28xxx miles. Maintenance regularly performed. (Mobil 1 0W-40 every 4-5 thousand miles...)
I was driving the car yesterday afternoon when about 2 minutes after leaving home the car's check engine light turns on along with the EPC light after a minute. the car started to stutter with light smoke. I drove home immediately to call the dealership. I scanned the car and it had two cylinder related fault codes. I believe 'Cylinder 2...' and 'Cylinder disabled?' Unfortunately I did not write down the codes as I was in a fury.
The dealership tells me to bring the car in as soon as possible 10 minutes later, I turn the car on and relatively heavy white smoke continues with excessive stuttering especially while in park. Additionally, the muffler sounded as if it was sputtering out the white smoke (1920s train in color and noise). I drove the car slowly to the dealership and noticed difficulty accelerating to 15 miles per hour. I did not try to go above that.
I just had the intake manifold replaced 4-5 weeks ago since I had a check engine light related to that.

My check engine light came on and I had it checked at Advanced Auto and it said it had to do with my air intake so I checked if it was leaking and the hose closest to the engine has a big rip in it so I taped it for now.

Last night driving home my cel came on and I didn't hear anything off so I finished my drive home and scanned my car. The only code that came up was the p0171 code. I know it's a at system running lean code and I have looked and researched the issue. Some of the threads I've read have had bad endings, or this has caused their car to throw more codes the longer they drove it. I know about the maf sensor, checking for leaks, possible 02 sensor, things of that sort. My car is an 05 mk4 gli, apr stage 1, 007 dv, brand new n75, and brand new plugs/wires. Oil was also changed about 1000 miles ago. I'm trying to do this all myself if possible.

Whenever I have my fan on speed 1 or 2, it makes this fluttering noise that comes from the passenger floor cabinet. I stuck my head under there while it was on and was able to confirm that it's coming from the fan that's located under the glove box.
I'm thinking about taking the fan out to dissemble it and try to figure out what's making the noise. It almost sounds like there's a leaf or something stuck inside rubbing against the fan.

I have 6600 miles on my Prius. When I first go my prius I increased my tire pressure to 40 psi. At 5000 miles I got an oil change and my checkup. Took a road trip of 400 miles and got 53-54 mpg.
Just before my fill up at 5500 I put a screw through my front passenger tire. The last two tanks of gas I have only gotten 45 mpg and was ready to take the Prius back into Toyota and ask them to fix whatever they did to the car.. To make a long story short I decided to check the tire pressure on all the tires again. Three of the tires were at 40 psi and the one Toyota fixed was at 35 psi. I inflated the one tire to 40psi and not I'm right back where I was on the mileage. 52-53 mpg.

We took our 2008 Prius in for a check engine light. The dealership said oxygen sensor was faulty. Changed that and had them change the serpentine belt while there due to cracks in the belt. My wife filled up the car the next day ( it took 13 gallons) but gas gauge was not registering a full tank. We drove 67 miles and I decided to pull into a gas station and see how much it would take since the gas gauge was not working properly. It took over 7 gallons.
