Passat (B5) :: Ratcheting Kind Of Sound On Start-up And Acceleration
Sep 30, 2008
I have a buddy who has an 01 B5 w/ 1.8t and 5 speed. He asked me to try and find out why it has been making a mysterious noise. I do all my own work, so I know a few things, but this noise has me stumped.
On startup, it will make an almost ratcheting kind of sound. Clattery, grumbly ratcheting sound... Goes away in a few seconds. It will also occasionally do this on acceleration.
Now, I am not hugely familiar with the 1.8t (in fact, my VW experience is largely a B4 TDI) so I'm not sure where to start.
One note though- I changed his oil for him, and the first startup right after the oil change the sound almost didn't happen at all. From then on resumed its obnoxious habit.
What this could be? Engine? Tranny? Something else? I didn't get a response over in the 1.8t area so I'm trying here.
Just recently his turbo has decided to contribute very little to power. You can hear it spool a little bit, but it's not what it used to be.
Just recently he had to have his intercooler replaced due to running over a semi tire. I have yet to pull his belly pan to look for loose fittings.

When I started the V^ Passat today it made a fluttering/imitation purring kind of sound...not re-assuring at all. What it could indicate? It only lasted a second then fadded out and ran fine.
maybe a belt tensioner or oil pressure regulator or something like that getting up to snuf?

I have a stock GTI MKVI and now if I turn or cut the wheel sharp to park (all at slow speed) I get a ratcheting sound from up front. It is not the suspension "clunk" that some lowered cars get.

Due to the clicking-ratcheting sound my 1997 Civic makes when I make hard turns or U turns, two mechanics (one drove the car) say that I need two new front axles at a cost of $400 ($200 each). I have driven the car like this for maybe a couple thousand miles before I looking into it. How much longer can I drive it like this before it gets dangerous or fails? I now only make gentle turns and so minimize the clicking-ratcheting sounds that happen only on hard or aggressive turns. The car only has 76,000 miles on it. Is it dangerous to keep driving it?

I have a 2005 F350 SD with 217K. It's got a Magnaflow aftermarket exhaust and newer OEM turbo. When I'm driving uphill and around 1800 RPM or higher, the engine makes this weird ratcheting sound when I let off the gas. It almost sounds like air is backflowing somewhere. It doesn't do it on level streets or downhills or when I'm below about 1500 RPM. The sound is not a metal on metal type sounds. It literally sounds like high pressure air backflowing somewhere or not being discharged properly. Also, I bought the truck used a couple months ago. So I'm not sure of all of the aftermarket upgrades done to the engine.

Just bought a 2005 4.6Lused. There is a "air escaping" kind of noise during acceleration. It sounds just like the AC system does sometimes after you turn off an engine. I thought originally that it by be AC related, but doesn't appear to be. At steady speed, it goes away, but comes on again with the slightest bit more gas pedal. In cruise control, it cycles on and off when the cruise accelerates up a hill,, etc. The sound is on the driver's side apparently close to dash corner.

Today on my 1-year-old RX 350:
moonroof makes a slight "ratcheting" sound when I raise or lower it,though Roof slides open and closed perfectly.

I have a 1997 Subaru Legacy sedan with a 2.2L engine with AWD. When I step on the brakes I hear a ratcheting type of sound and feel pulsations in the brake pedal.There is no problem with brake performance that I have noticed. We have replaced the front rotors and front brake pads.We also replaced the rear passenger side brake caliper. It still makes a loud ratchet/groaning-like sound. It makes the sound when you first start braking after starting the car and intermittently while driving. It's not constant when you step on the brakes.

It is a 2002 or 2003 Chevy truck with a diesel engine. He was going down the road the other day under normal driving conditions when the motor made a racket and then white smoke started coming out of the back like a chimney. The truck will still crank and run (and smoke), and now there is a knocking or tapping noise that is coming from the engine. The engine is running kind of rough, and has the tapping or knocking sound, but it will calm down for 1/2 a second at which time the rough idle and noise stop, but quickly return. There is no engine code showing, so my code reader is useless. I once had a Chevy 350 with a spun main bearing that sounds similar, but the motor didn't idle rough or smoke. I don't know enough about diesel engines. I was told there was a possibility of a bad injector pump or bad injector itself. Is there any way of testing this yourself, or does it require a shop trip?

For about the last month or so my car has been making a strange thumping kind of sound that is constant with vehicle speed. slow or fast. changed the rotors, pads, hardware, shoes and machined drums. also has a slight pulsation when coming to a stop. Thought it was the tires but they look good. can not find anything wrong.

Well I put some HID light in my 2001.5 GLX Passat an I notice that they are aiming kind of low. I know which slots are what. Ones for highering and lowering and the others from side to side. But when I'm trying to adjust them the up and down they work but when I'm trying to adjust the side to side they seem like they aren't moving. Which is a better way to tell? I put it right next to a wall 25 feet away in the dark but I really couldn't tell still. Plus it's not a straight line either. Since I have the perjecter lights their should be a cut off line right? Also is it like turning it right to make the light go right or left to go right, for the side adjustments?

This morning I just began noticing a low pitched whining sound when I accelerate at low speeds (below 30 mph). The sound seems to disappear at higher speeds for some reason. It bothered me so much that I arranged to have all the timing belt service done....I have been putting this off....84K miles now on a V6 Passat. I'm thinking it is the water pump noise, but I am not an expert on cars like most of you are. What all SHOULD be done when you change the timing belt?

I bought a used 2008 Rx350 with 75,000 miles 2wd ... The car runs great, gets the advertised fuel mileage etc.. The engine seems (is)noisy to me at idle. Can't hear it while driving. sounds like poorly adjusted valves.

If you have an intake and are under heavier acceleration, do you get any vibrations in the car while getting that growl sound?
I have the intake pipe zip tied so that it is away from the brake lines but I'm trying to figure out if the vibes are coming from just the sound frequency or something or if it's something else.

Just curious. I installed a set of Drive Gear springs on my auto passat and I have a "swoosh" kind of noise coming from I think it's the left front. (I think, might come from the others) It happens a lot on small bumps.

I just bought a 2006 Passat 2.0T FSI about 3 weeks ago, love the car so far. My only concern is within the last week i have started to have a little bit of a lack of power. The engine will give a surge of power and then kind of slow down for a minute then a surge of power and then slow down. Also the other day i started it up and it had a little bit of a rough idle until it warmed up, don't know if these are related. Has right around 91K miles right now.

So I had a weird problem this morning. I have a 2013 Elantra GT with about 27,000 miles on it. This morning when I went to start it, it tried to turn over once then stopped. Every other time I tried turning the key it didn't make any kind of noise and wouldn't start. Despite all the lights and radio and windows working fine, I still tried jump starting it, but to no surprise, that didn't work at all. Finally I tried using the shift lock to shift into drive then back into park again. When nothing worked, I tried making a complete guess and shifting it into neutral, when I was in neutral and tried turning the key, the car finally started. That happened about an hour ago and the car has been starting fine since.

To get straight to the point: I have a 2013 GTI that has recently started making a screeching noise on cold starts and during engine acceleration (not necessarily heavy load, but actual engine speed acceleration).
I recorded a video of it this morning and it is very easy to discern the sound. The car is APR stage 1 tuned and has a south bend clutch but I don't think either of those are related to the sound. The water pump has been replaced from the service bulletin, the auxiliary belt tensioner has been replaced because it started to make a noise (this noise is completely different). Otherwise the car has never given me an issue, it has been maintained exactly per the OEM repair schedule other then oil changes every 5k miles vs. 10k. I use mobil 1 0W-40 oil.

I noticed my 3.6L 4Motion is making a hard thump/ticking sound when the car accelerates from stop, and also on turns. I'm going to schedule service for the car next week and I wanted to get a little educated insight. This is strange because I just had two of my cats replaced last week.

Wife's car won't start today. Just get clicking sound when I put the key in, and a random message about airbag defective, or steering lock defective. We tried jump starting, but no luck. Do we have to pay to get it towed to the dealer, or will should they take care of that? I guess the starter went out?

Car will not start. No sound from fuel pump while cranking. Pulled up the carpets and pulled the cover and connector from the fuel pump. Ive heard the relay is the common problem. I tried checking the voltages on the harness and we get 0 while cranking. Pulled the relay and we get a resistance from T pin to pin 86. I did notice a yellow color on the white connector on the fuel pump itself around the middle two contacts.
