Just installed a Phatbox in my customer's Touareg. With engine running, there is a hum which turns into a whine with engine revving up. VW Service does not have a fix from factory yet. I suspect it needs a filter (capacitor) to suppress RF coming from the ignition system.
View 6 RepliesI have a 2007 SE with 3.3L and Auto transmission. 70k miles, regular service performed.
Starting a few months back, I've noticed a low volume hum/whine coming from the engine compartment. I notice it more when I'm in drive, but also notice it to a lesser degree when in park and revving. In drive, the sound gets just a bit louder and higher pitch, until shifts, then lowers at low RPM, growing again as revs move up.
since it happens in park, I'm thinking it is engine related, not transmission? (I usually change oil around 4k, sometimes as high as 5k)...
I have a 2000 model accent manual trans its just recently clocked 200 000 km I know the car has had problems but they are getting worse. Occasionally I have Problems starting the car in the past but it usually takes no more than 5 turns to get started but this is getting worse the other day it took about 5 min maybe more to get the car started I am guessing my starter motor probably Needs to be changed.
Next problem yesterday after I put a full tank of Premium 98 in the car its starts to rev itself changing the sound and note of the motor running constantly it has done this in the past but not so severely and It only seem to do so after putting petrol Especially when I put fuel From a servo I don't usually go to the car would have stalled more than once but didn't only because I tried to keep the revs up when it sounded like it was gunna die also I am pretty sure my fan was making some weird noises but the car has had no engine Light show and no Overheating.
My car is a 2005 V6 Touareg. It has 60.000 kilometers on it and had no major issues to this date. It was well maintained. Recently, it developed a problem with starting. Before I go into more details, I have to tell this: my car has two batteries, and they are in perfect condition, verified by the dealer. The spark plugs were changed at 45.000 kilometers. It has no rough running characteristics under heavy acceleration or any hesitation - from what I read, symptoms for bad ignition coils-.
When I turn the key for ignition, the engine turns over but instead of immediately starting, keeps cranking for 2-3 seconds, and finally starts with a slow idle. Sometimes the charging light remains on for several seconds due to the difficult starting and the slow idle, but this does not last and the cars start idling normally, as if nothing happened. This happens when the car sits overnight and the engine is cold. Once it starts, I cannot get the car to do this without waiting overnight. Summertime weather seems to contribute to this but I still get it in the cold winter weather.
Strangely, if I do not use the car for, say, 3 days, the car starts like the day I bought it, without the hesitation.
I took it to a dealer and told them to check it but they said it start normally. They checked to see if the car registers any error but it does not. I am sure of the quality of the fuel I am using. In any case, I tried several different brands from different stations just in case, but this did not make any difference.
Bad ignition coil, idling sensors or mechanism, something wrong with the intake manifold? Carbon build-up (although I have to say this is not likely since the catalytic converter seems to be fine which leads me to believe there is no excessive carbon buildup).
I have a problem in my Touareg 2005 R5 TDI, my heater blower works fine while ignition on. When I start the engine, blower starts for a moment and then stops .This problem happened first time before 2 months and suddenly blower worked fine till today.Now i have the same problem.I tried to replace the blower motor but nothing changed.
View 1 RepliesI have a whine that occurs while I am between 70-73mph. The sound goes away when I take my foot off the accelerator. I can sometimes but not easily make it occur at around 40mph as well. The sound is barely noticeable, but definitely there if you listen carefully. What it could be? I have a late 05 model and I have tested without the roof racks.
I also would lke to know if it is normal to hear something similar to a chain turning, this time when you let off the pedal and let the car just cruise. You can only hear it with the windows open especially inside a parking garage. I would think it is normal for the V8 engine or AWD setup, but not sure.
V8 driving from start up in cold conditions (below +15 Deg F) car parked outside overnight, I hear a transmission whine when decelerating. The whining rises and lowers in pitch as the tranny downshifts upon slowing down. It has only started doing this recently.
After the car has warmed up, the noise disappears. However, I find that it is strange that the car would suddenly start doing this, as I have driven that car in years past without the noise. If it had I would put it down to normal warm up noise.
I have noticed a high-pitched whine coming from the front end at high speeds. Above 90-95 mph any use of the accelerator results in a high-pitched noise, unrelated to RPMs. Past 120 it starts sounding pretty bad/loud. My guess is that the fuel pump is sucking so much gas that it is having issues, or the throttle control is just unhappy in that range.
View 4 RepliesThe vehicle is a 2005 Touareg 4.2 v8 with 81k miles. I purchased from a dealership and have been having nothing but problems from the day I purchased it. (2 months ago) the day after I purchased it check engine light came on, headlight range light, air bag light, and now this noise I have owned about 15 vag cars and also own vagcom no codes pertaining to this noise... Above 10-15mph there is an intermittent whine (high pitched) for the most part the noise is there most of the time.
It does not stop when in neutral not effected when the air is off or on, does not change if you down shift, no change if the wheels are turned. I broke down and took it to a very trustworthy Audi shop in the area and you guessed it the entire way there no noise... The tech drove it no noise so I had them flush and fill the trans as it was due for it anyways. They informed me that it was dirty and I figured that it may have taken care of it. Well after a 20 minute drive home the noise started again! I took a short video....
All of a sudden after coming back from an Alsp ski trip some sort of loud front drivetrain whine has developed. It's an 05 V8 with 4k miles on it. It's drivetrain because the whine scales with road speed and not engine rpm. It seems to only come from the front too. It starts to get real noticeable around 50mph and increases.
The odd part is I can turn the steering wheel maybe a quarter of a deflection either direction and the sound virtually disappears. I checked out the tires and the tear is good and no usual wear. I am thinking maybe a wheel bearing or a transmission output bearing. I just don't see how anything else could make this whine come out of nowhere so quickly.
This winter when car warms to temperature and with climate control in auto I get fairly loud grinding/whine sound from area behind radio.
If I turn fan off, still get sound; like dampers are moving and rubbing trying to adjust. Set vent buttons to center or top and will stop for a while. Reset to auto and noise starts with or without fan on.
Last trip to dealer they claimed it would not do it; seems like the car has to be warm and outside temperature below 35F. Do the dampers work - vacuum or electrical? Don't remember the problem last winter, this year have had condensate tsb done and also had dealer replace main control module. Wondering if they could have pinch hose or some how caused binding.
Whenever (almost every-time) I start my Treg the A/C comes on. It doesn't matter if I turn it off before (quad zone btw) turning off the car, it still comes on when I start it back up. The fans will be all the way down, but still on (though I don't think the fans are going at all.) Any way to disable this?
View 3 RepliesI've just acquired a 2008 Cranberry T'reg V8 with the Techno and Lux packages. Whenever any function on the Nav/Radio unit is activated, the radio turns on. For example, when shifting into reverse, this activates the reverse camera screen -- and the radio also turns on. Likewise, if I turn on the navigation screen, the radio turns on. This is kind of annoying if I don't want the radio on, but want other functions activated. Is there a setting that I'm missing? The only thing I can figure is to keep the volume setting at zero.
View 2 RepliesWhen I make low speed sharp turns, (like trying to make a U or K turn) the Treg kind of "lurches". Is this common? Is there a fix?
My Treg is a V8 PPS and is one of the first here in the US (took delivery 7/7/03).
I am due for an inspection for a 2004 Camry (4 cyl.).
I had the engine light come on with a P2231 or P2238 code on my OBDII tool. Car was running fine, no weirdness whatsoever. But I went ahead and changed the front sensor (Bank 1 Sensor 1). As soon as I changed the code went away and it is not coming out anymore, nor are other codes.
However, the engine doesn't idle after 5 minutes running. I have to keep revving it up at the light to keep going. I shut it off and it turns on no problem. But then it doesn't idle. What a pain, I used the Bosch O2 sensor bought from AutoZone.
Recently, when I start-up my 2004 V8 Tourareg, my downhill assit feature turns on. This occurs on "level" ground. It will go away when I turn off the engine and restart. I took it to the dealer and they said I needed a new rear differential motor. Only have around 4,500 miles on the SUV with zero off-roading time.
View 1 RepliesHave a seat and/or steering wheel that squeaks? If so did your dealer fix them? I have a driver's seat that squeaks when it adjusts for both entry and exit. It sounds like the leather is rubbing against something. The steering wheel squeaks during turns. I have about 3500 miles on my rig and the seat squeak appeared about 800 miles ago and the steering wheel squeak appeared about 500-600 miles ago.
View 9 RepliesI was heading home last night from work and noticed something odd. It was the first pretty cold night that we have had around 20-25 deg. and I took off from the parking lot like normal.
When I got to the first stop light about a mile down the road I heard what sounded like the engine revving up right when I took my foot off the gas pedal. It did this as I coasted to the stop light. It also did it again at the next stop light just up the street. I thought maybe it was the heater blower, but It really sounded and felt like the engine revving. The car did not accelerate or anything, is this part of the warm up or normal? I also have the lower grill blocked but I don't see how that would make any difference.
Pretty nice condition 2003 1.8t Passat 5 speed yesterday with 45k miles. nice price, mint interior, only a few minor blemishes on the bumpers.
Anyways, I was noticing that the gas pedal needs to be pushed in about half half before the car wants to move. I do not believe it was the clutch going bad as the engine wasn't revving when i was letting the clutch out, it just didn't seem to move until the gas pedal was half way down. again, no clutch slippage, engine was not revving.
I noticed that when I'm stepping on the gas pedal, revving up, when I release the gas pedal I can hear the engine revving up some more instead of slowing down.
When I release the pedal even if the revolution light on the dashboard shows that it is slowly dropping, the engine is still making the noise as if I am stepping on the gas harder for about a second.
Example: I am at a stop, when I start going from 0 to 30 mph, if I release the gas right away that's when I notice this issue.
This doesnt happen when I'm cruising on the same speed and suddenly release the gas.
I wonder if this is an indication the my tranny is having a problem.
I have a 2013 prius C 2...
I have noticed a couple times now on my Automatic S that the engine keeps revving an additional 1,000 - 2,000 rpms when I am braking going down a hill. Is this normal? It doesn't occur on flat roads or going uphill, but only downhill. It's almost as if it downshifts when I brake. Not sure if this is normal or not, but it just didn't feel right.
