Passat (B5) :: TDI Resonance Noise At 1700 RPM
Jul 18, 2006
I own an '02 Passat 1.9 TDI 130, approx 100k on the clock, runs like a dream apart from one thing:
A resonance has appeared at about 1500-2000 rpm. Sounds like a knocking of an airbox or something, had the car on ramps but no luck. not the exhaust or anything obvious like the engine cover.
Happens both when moving and standing still. not too loud but enough to anno. What it could be? worn engine mounts? the lights shake quite a bit a tickover....

I have a 2008 Mazda3. The car has a replaced engine with 24,000 miles on it. The engine was put in before I bought the car.The car and engine run like a top; except at certain RPMs and when in gear. When I have the car in any gear (auto), the engine makes a rougher noise at RPMs 1400-1700. As I apply more gas, the RPMs seem to get stuck at 1700, then it will break through and run smooth 2000+ RPMs. The engine sounds perfect at all RPMs except 1400-1700 when in gear. When I have it in park and rev the engine, the engine sounds perfect at all RPMs.

Getting a weird resonance around 1,500 rpm? Noticed while driving at town-speeds. For a while I thought it was coming from the subwoofer, but I now know, it's the engine.
Car in motion, I engage the clutch, and watch the tachometer needle go down. Just as it passes 1,500 rpm I get this deep, bass noise from the engine. For about half a second, then it fades as the needle goes further down. I can replicate it while parked, at idle, by just pushing the throttle enough to get the rpm at that range. Boomy.
On cold days sometimes the engine runs around that range until it warms up, which makes the car sound really kick ass. In fact, someone heard it in our office's garage the other day and commented that my car sounded "too powerful for stock"...
It's by no means a "bad" noise, in fact I kind of like it. But I'm still wondering if it's a sign of something suspicious.

I have a 2011 stock GTI with DSG. 7,000 miles. I just noticed the car has a resonance / vibration / cyclical pulsing / cyclical drone at EXACTLY 65MPH and again at 75MPH. It feels like the pavement has rumble strips every 100 feet or so. I feel it in the floorpan and slightly thru the pedals. You can also hear it- mid-pitched- like a higher male voice tone. It pulses about every second or slightly less for about a half second. It is slightly faster at 75MPH than 65 MPH.
There is NO shimmy in the steering wheel. It is rock solid stable.
I can't place if it is coming from the front, rear, left or right.
Happens in every gear- regardless of RPM.
Happens the same turning left vs. right.
Happens with and without AC on.
Happens with and without the brakes on and/or parking brake on.
I rotated tires front to back with no difference.
Of course, I spend most of my driving time at these speeds and it is making me CRAZY.
BAD WHEEL BEARING??

After almost 12,ooo miles, I'm starting to experience some kind of buzzing resonance that come through to the dash, console, and can feel it in the gas pedal. It's weird because it will happen when accelerating and decelerating too, but not it's not a constant occurrence. I wondering if the motor mounts are loose? The ICE runs great and the transmission seems to be operating as smoothly as ever. It's just odd that this started just recently.

The engine light came on with only 1700 miles on it. Is there a check list that I can go over to find the problem. I want to check it out myself before I take it to the stealers I mean dealer Or is there a way I can check it on the MFI?

My 2005 yukon runs rough between 1300-1700 rpm, seems to run fine at all other rev's, doesn't matter what gear I'm in, (trying to troubleshoot put in low to see what it would do, same problem) if it's in the rough zone and I punch it it smooths out and runs fine, I've tried injector cleaner (Techron), premium gas, but it still does it....

I have 2011 Sonata Limited 2.4L I have a rattle that seems to come from the engine compartment near/thru the dash/driver area. I am getting pretty good at replicating the issue. When I accelerate or decelerate thru 1500 - 1700 rpm the rattel/vibration happens. If I can continue to keep the same rpm level the rattle remains. It tends to be even more frequent when the AC is on. I have had the dealer look at 2-3 times and they cannot seem to remedy the problem.

Recently bought an Audi A4 Quattro from a dealer with 112,876 miles on it.. The car runs absolutely beautiful, it up-shifts and downshifts without any noticeable issue, it changes gears without any issue, however... When I am trying to maintain a stable speed of around 35 - 40mph and my engine hangs around 1700RPM it'll bounce up and down slightly..
The revs will hop between 1700RPM up to around 1750RPM and then back down, and then up again.. It's hardly noticeable and the only time it causes any issue/delay is when it hops above 2000RPM and then back down... Is the torque converter the issue or what else could be the cause? Timing belt has been done, spark plugs have been checked, oil has been changed.

I have a 2008 F150 with a 4.6 litre in it. Last year I dropped a couple of plugs and had a factory new, second generation 4.6 installed. The motor only has about 25,000 on it while the rest of the truck has about 160,000. I was driving back roads in western Mass and went over a small, about four inches deep, pothole. I was driving about 35 miles per hour.
I didn't get any associated master warning lights. The RPM started rolling back from about 1700 to 0, and when they got to 0, the engine shut off. There was no previous sign of a fuel pump going bad, or of a bad fuel filter, which is also less than a year old. The truck has plenty of electrical power and turns over strong but won't start.
I checked the #9 fuse as identified in the manual but couldn't find an actual relay for the fuel pump, so I'm assuming it just has the 20 amp fuse which was good by the way. I'm thinking that the fuel pump would have given a few warning signs, but maybe not.
I did check the emergency fuel shutoff switch to make sure that it had not activated when I hit the pot hole and unless I'm resetting it incorrectly, it doesn't seem to have been set off.

I just bought my first truck ever, ended up with a 2002 F250 SuperDuty V8 5.4. I'm fairly handy with vehicles but can't seem to figure out the issues I'm having. I searched the threads and have tried a number of this solutions, but to no avail.
1) The truck runs smooth above roughly 1700 RPM, but between 1300&1700 there is a distinct stutter and shaking of the entire truck. Although the check engine light does not come on the Scanner indicates a misfire in cylinder #3 and I've replace the plugs and coil, but it's still there. Fuel filter has been recently replaced and seafoam run thru the tank and vacuum line. The mechanic at the local mom & pop shop said it is most likely a damaged valve in #3. Am I missing anything? Do you think a valve job is necessary?
2) When I got out of the truck tonight the radio stayed on, I tried the WD-40 fix (no luck), additionally checked the fuses (all in proper condition). Not sure if this relates but the auto door locks started acting up as well and the door ajar light stays on all the time. I saw a post about a "VSM" but what or where that is.

I have a 2012 4x4 EB CC. In 6th gear, on the highway between 1200-1700 RPM's, during a slow acceleration, it feels like it is missing or shuddering. It is most pronounced going up a hill, and/or towing something. As soon as you get above about 1700, it goes away. Rig needs to be fully warmed up (not just the engine, but tranny/drivetrain). Needless to say, this is generally from about 52-65 mph, which is most highway (not freeway) driving I do. At times it's so bad my wife says it's time to get a Chebby.
Had it in about a year ago, couldn't duplicate it. Took it in this last week. Did the TSB on the plugs, and was told that would fix it. It didn't. Took it back in; they couldn't duplicate the issue. Rotated the tires hoping that might do something. Took the head service guy for a ride, and made it happen; it was very obvious then. It seems like the tachometer should bounce or shudder a bit when it's doing it, but nothing. It's going back in on Monday to see what they can do.

I have a 06 f350 with 5.4 140k miles. Recently it has been shaking bad on idle but only in gear and it's hard to start when cold. The exhaust is moist at all times and the fluids never leak. When you floor it it hesitates feels like it's overly rich but if you let off a little it stars to pull again. Also while cruising at 1500-1700 rpms in any gear it will surge and skip. Only time it will miss and the CEL comes on is over 4000 rpms for a random misfire. Just put new coils in new fuel pump and filter. There has always been a cat code but it never effected the drivability. Could it be injectors?

The video below IS NOT my truck, though my truck makes the same sound. Mine isn't nearly as loud as the truck in the video at idle, but gets much louder when under load at about 1700-1900 rpm. If you take it easy accelerating it doesn't get any louder than at idle. At cruising speed in third it isn't audible. The trans in my truck is a 1979 C6. Again, not my video. Same noise though.

I've have a rattle right here since day one of owning the car (5 days ago!) -- If I hold right on that box while I drive, it goes away immediately. It seems like the piece isn't "clicked in" all the way ...

So after getting my car back after 7 days. Was getting my Heater core replaced. I now hear a clicking noise from my fan. Doesn't matter if its hot or cold it makes this clicking noised from the Fan. It does it from Low to Mid but stops at high speeds.
What could it be? Here is a video of the sound. [URL] ....

I just started getting a humming sound at 55+ mph coming from the front left side of the car. the pitch of the hum changes with the speed of the car and goes away as you slow down. i can't hear anything when i roll the window down because of the wind.
i plan to let it get worse until i take it to the dealer. they do not fix anything unsell it is totally broken.

I just brought a Passat b6 2010 with 10k miles. One thing is concerning me - DSG.
I have no problems as for noise or weird behavior when moving or changing gears at low or high speeds, low or high RPMs, but when i am at a full stop (with parking brake on) and shifting from P to D or from D to P, I hear a couple of clicks (sometimes 2 clicks, sometimes one click, sometimes 3 clicks) that happens between half a second to one second after i shift. It sounds like a stick car is being shifted, only louder. The clicks sound weird and "dry".
I made two videos, first one is outside and the second is inside a garage so it is possible to hear it better. Pay attention as it happens just after I select either D, R or P. It happens when moving from:
P to D - louder
P to R - louder
R to N
P to N
D to N
And vice versa.

Just wanted to know if its common to see tires on a '06 B6 3.6L with stock 17" wheels, start to hum from scalloping after just 12,500 mi. They sound like a truck with super duty mud tires. These are the stock Michelin HR 17" that came mounted on the car at time of delivery. The car has been to its routine service intervals. No jack rabbiting. Just freeway driving. There's plenty of tread on them, and the noise seems to be coming from all four.

On the way to an appointment an big noise started, like the exhaust was broken. See picture, how can I fix it, pull the part but do not see how the portion that got loose is hold in place buy that metal plate. Or do I need to tale it to the dealer.
Notice that there is no a lot of welding to hold it in place, that is amazing. It looks that it should be weld on the outside to avoid this problem.
