Touareg :: 2004 - Noticed Sudden Acceleration Hesitation
Oct 14, 2009
My truck is just turning over 100k miles and I still love her like she was new. Recently I've noticed accelerator hesitation (especially in slow traffic) that wasn't there before. Also something new, the fuel system no longer bleeds pressure when I remove the cap to gas up. I think the lack of fuel system pressure has something to do with the hesitation. I did the easy thing and replaced the gas cap. I asked the dealer and they checked fuel pump(s) output pressure and said they were normal.

Well - took my car into the shop today for the death lag, harsh shifting, and acceleration during braking. I've read much on this site about tranny flash and ECU flash, and was hopeful there was something available for my 2004 V8 (I just purchased it in late October, but was unsure what TSBs and campaigns had been applied before I bought it)...
In the end, dealer was able to replicate/experience the harshness problem, but was unable to come to a confident solution. My 86xxx VIN V8 Treg was not due/eligible for the much discussed tranny flash (my engine type was right, but the tranny flash was not listed for my car). In fact there were no recalls or campaigns due for my car, and there were no faults on the computer.
The dealer stated the cause as "Harsh shifting patterns". and fixed via "Reset TPS and TRANS". Essentially, I was told, let the adaptive driving feature relearn, and hopefully replace the previous harsh shifting pattern. My ride home from dealer was short, so not sure if there was any effect - but I'm not confident.

When checking the oil (dipstick) the other day, I smelled a "different" smell . . . so I turned the oil cap and saw GREEN oil on the bottom of the cap. I've used (use) ULSD/B5 in this TDI .

We have a 2007 Prius and have been very happy with it overall. The right rear tail light keeps burning out and we keep taking it back to the local Toyota dealer for replacement, but they have been very good about it. Though an annoyance, if that was the only problem we had I would not be here right now typing this.
Today my wife was driving and came to an intersection at a red light to make a right-hand turn. She braked coming into the turn and as she made the turn. What happened next scared her and is very concerning to us -

Here's the story on my truck. Spits and sputters between 40-60 during heavy acceleration and on rare occasions will jerk/pop while at a steady speed. No engine or wrench lights. I thought it might be the fuel filter and changed that, it didn't work. I also ran two bottles (on 2 separate occasions) of Duralube extreme fuel system cleaner, that didn't work either. So, I took it to the Ford dealer for a diagnostic. They had a hard time getting it to act up but said it finally misfired on #8 and recommended replacing the ignition coil and plug. I did that, still have the same symptoms. So, I thought it might be the fuel injector and changed that. Still same symptoms and ZERO dummy lights.
After several YouTube videos, I thought it might be the TPS and got one. Before I changed that however, I cleaned the Mass Air Flow sensor, still same symptoms. I finally changed the TPS, but the engine wouldn't start or run at all, no warning lights yet. When I put the old TPS on, it would run. I unplugged the TPS and it still ran but very rough. Now the engine light IS on! Thinking I purchased a bad part, I took it back to O'Reilly's and they warrantied it out and gave me a new one. I had 19 PO codes. I changed the TPS again, and, it won't start or run at all. Put the old one on and it runs. They cleared the codes and told me they think it could be the ECM/PCM.
Why will a new TPS not work? I still have the same issue of hesitation @ 40-60 during hard acceleration. No hesitation during a moderate acceleration.

Change the oil on my V6 2005 Touareg and noticed a slightly reddish color. Oil not burn.
Car was park a dealer for more than three weeks while they replaced the A/C.
My touareg never needs extra oil between changes and does not burn the oil. All temperatures are normal at 100 degrees weather.
What would cause the oil to get that reddish color?

What a year 2014 has been. I had a 2005 F250 6.0 that was stolen in March and totaled when found days later. My insurance gave me enough to pay off the loan and render me the obstacle of replacing it. I got my F250 pretty cheap so replacing it for the insurance pay out was non-existence. I ended buying a 2007 F150 EC 4X4 w/ the 5.4 and having 97,000 miles on it. Just as luck would have it, I had the F150 for about a week before the cam phasers went out. Luckily the warranty covered it enough to put in a new LKQ reman engine.
I got the truck back about 2 weeks ago and put 1,000 miles on it in a very gracious form. I have noticed since then that despite letting it warm up for 20 minutes, I could put the throttle on the floor and the outcome was very poor. It was almost as if I was attempting to pull a house down. I couldn't even get the tires to spin at all, not even on wet pavement. Now I know this is not my old F250 6.0 turbo diesel, but really, I expected more from a new reman engine! They used all components from the old engine except for new spark plugs and a fluid change. Why is this "new" reman engine so weak?

I have a 04 V8 with a hesitation in the shifting. The VIN is in the 44000's. The dealer says there is nothing they can do to flash the tranny, they've tried and it won't let them. I found the TSB referring to the engine code and they insist it doesn't apply to my vehicle. Is there anyway to find out for myself whether or not it is possible?

To make a long story long, my v6 developed a hesitation on startup after being driven and then sitting for a few hours. Sometimes so bad it almost dies - popping noise from under the bonnet and lurching would best describe the symptoms, the harder you press the accelerator the worse the symptoms. After about 5 to 10 seconds of driving goes away and never happens again until it sits of another few hours. Somewhat disconcerting when you decide to pull out in front of traffic....
Also recently started surging on freeway slightly and worse going up mountain passes at freeway speeds, may or may not be related. Does not have anything to do with brake predal being depressed, I can pressed the brake pedal and accelerator pedal at same time and car will rev and accelerate immediately upon brake predal release.
Talked to service advisor who told me that I needed to be sure and run premium in my vehicle which I always do. A couple days later with continued issues talked to my service advisor who then told me that the fuel in the NW had a problem and that I needed to run only mid grade and that would take care of the problem, which it did not. Talked to my service advisor again and he said that I needed to run only regular, that regular seemed to be taking care of the problem with the regional bad fuel all along he has been claiming that other manufactures are having the same problem Volvo, Saab, Ford on certain models.
I went along with one tank of regular did not make a difference on the hesitation, but made my vehicle more underpowered than normal. At this point I made a 2000 mile trip to CA and used CA fuel which is another completely different gas formulation than any other state in the west - 4 tank fulls of CA fuel made no difference same problem, both hesitation and surging. Took it back to dealer who then tried to tell me that it is a whole US problem with fuel....I wanted to call BS at that point, but agreed to let them keep it for a checkout, they kept if for 24 hours checking it out no codes, VW told them to run injector cleaner through it.

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.

Since we know that most VW service sucks, I'm taking my 04 V8, Nav/Air Susp 35k miles in tomorrow because the whistling/rubbing noise was bad enough on the ride home from work last night that it started freaking me out.
I want to tell the service department to at LEAST check the following:
Whistling: Gets worse with speed and when the car gets warmed up. Sounds more like rubbing when you get going. Check the drive shaft bearing.
Running Gear Fault: Check air suspension piston rings ( I need to look this up again) Something to do with the air bag or air pump seal.
Hesitation: There should be a TSB for this that can be fixed with a computer adjustment.

People are complaining about sudden acceleration with the DSG transmission. They had to up the warranty to ten years and fix cars too. After I read that I realized my TDI DSG has this issue but I just chalked it up to my driving. Sometimes when you hit the gas the car jumps B/C it drops a gear when it's not called for. I can't picture VWoA even entertaining this. Does the phrase "operating as designed" sound familiar?

I have DTC code P0100 so I got to the camshaft position sensor and noticed oil in the sensor. I can't imagine an electrical sensor is a good place for oil.

The owner of the car claims that there was sudden unintended acceleration, and it was 09' Sonata.
Video .....
I thought this should be very concerned to us, since we all drive 11' sonata & up. I heard Hyundai installs some kinds of system to prevent this incident to all cars manufactured after May of 2012.

My 2008 Volvo s60 did this in not one but two directions Volvo sent a corporate engineer but he found no problems but the also refused to check the ECM even after I insisted that this car always had low voltage issues...

I have an 04 V8 and have consistently noted a valve(?) clatter noise under moderate to hard acceleration. I mentioned it to my VW sales associate and he stated this is typical of this engine and that after warm up it should no longer occur. I hear the clatter at any time, warm or cold.

I've read several reports about failed water pumps. Well, Pearl stated leaving drops of pink coolant on the garage floor a few weeks ago. I thought perhaps I had overfilled the overflow tank so I just ignored it. Finally warmed up so this morning had a look. Water pump! Pulley had lots of pink decoration all over it.

While driving on the highway, I experienced sudden acceleration of the RPM's only on my 1997 PT Cruiser. What would cause this? I had to stop and shut the car off and it was okay when I restarted.

Clunking noise heard during stop, start and sudden acceleration, sometimes very loud sometimes very soft or almost non existent. Hard to locate as well. Feels like I'm about to loose my axle!
My BMW is a 1995, 530I with 154000 miles on it.
