Passat (B5) :: Weird Noise When Shift - Vacuum Leak

I have a Passat 1.8t b5.5 with 150hp

Some months ago I chipped it and it drives very good and I also changed the diverter valve to a 710N.

But now it is fast, but sometimes it just feels like it doesn't hold boost as it should. and I hear a very loud psss sound just like a BOV when I shift. Could it be the 710N which has been broken? Or is it a vacuum line to the DV that has a leak?

Passat (B5) :: 2002 1.8t - Car Has Weird Whistle Noise

I was noticing today when i started my car that it was making a whistle noise. So naturally i popped the hood to find the source of the noise. It is from this hose that connects to my header it has this crack in it and it is sucking air in. My question is what is the name of this hose, and what does it do?

Ford F-150 (2004-2008) :: Weird Noise On Acceleration Sounded Like Exhaust Leak

Well lately I haven't driven my truck much. Usually only on the weekends if Im lucky. Well I drove it today and I noticed this weird noise on acceleration. I have the cam phaser tick and have had that for about 50k miles or so. I started to think I was getting a manifold leak and that's what I thought this noise was until when I pulled over and put it in park and revved it up I did not hear the noise again.

It only does it when you hit the gas until you get to a steady rpm. I only drove 5 miles or so. So I couldn't do much testing cause its late and I got to get up in 4 hours. I don't even know how to explain the noise. It kinda sounded like an exhaust leak but it was more of like a lite thud noise I guess. Like I said it only does it when I hit the gas when its in drive but not in park. I tried to explain it the best I could. I just hope its not phaser problems cause I don't want to dump a bunch of money into it.

Golf VI R :: No Turbo Boost - Weird Sound When Hit The Gas

I have a 2012 R with 85,000 miles, APR chip running 93 octane with a HPFP and VWR cold air intake. I was driving my car today (slow driving on highest) and all of a sudden I felt no turbo boost, and heard a weird sound whenever I hit the gas. Car moved but would not get above 3500 rpms and couldn't really get past 60 mph. Again, absolutely no boost (I have a boost gauge as well to verify).

About to drop off the car at a shop but had a couple questions:

1. If the turbo is blown, can I still drive the car to the shop (not too far) without damaging the engine itself?

2. if the turbos needs to be replaced, what are my options besides getting the stock turbo replaced, without getting some crazy setup? This is my daily driver and I don't want to spend money beyond what I need to get it fixed, but it there is a stronger more reliable turbo for about the same as a OEM, I would want to consider... Also price for OEM replacement??

3. Without the mechanic looking at it, I'm just assuming it's the turbo but what else could be the issue? All the lines looks intact and intake is fitted correctly. I did have issues with my cam follower getting damaged at 45,000 miles (there was a hole in it) and I have been replacing it every 20,000 miles since. Didn't have any issues for 40,000 additional miles, but could damage to that cause turbo failure?

Passat (B6) :: Weird Popping Noise Frequently?

So when the car is idling(warmed up) I suddenly have a random popping noise coming from the front passenger side of the car. It is about 9 pops evenly spaced about every 1/2 second and then it stops. This is all while not moving....Like when sitting at a light. Then about 5 minutes later it will do it again. It seems its becoming more & more frequent.

Golf IV / Jetta IV :: 2001 - Weird Turbo Spooling Sound By Passenger Side?

I just got a 2001 Jetta 1.8t 100k miles, and had some repairs done - timing belt - K03S Turbo - Forge Tip - 2.5 Turboback Exhaust. I bought the car without a working turbo, yesterday I got the car back from the shop and it was a night and day difference..... but to my point, today I had some CEL's pop - Charge Pressure control positive deviation, Pressure drop between turbo and throttle valve, and secondary Air injection system incorrect flow detected. Now I have never owned a turbocharged car before, but when my windows are rolled up and im accelerating, I can hear what I am guessing is the turbo starting to spin over by my passenger side(2k ish rpms+) except it doesn't have clean spin sounds, kinda sounds like bearings are goofed or something. This noise only happens when I am accelerating or cruising? I also have felt really no change is boost or power!!

Golf/GTI VI :: Loud Turbo Whoosh Noise - Boost Leak?

2012 TDI ... OK so out of nowhere, my car is making loud turbo whoosh noise, while I love the way it sounds, it's not normal or intentional, so I don't like it lol. I have an AWE intake, and a gutted turbo resonance damper. Is been fine and same sound ever since those mods but now out of nowhere it is really loud with the whooshing of the turbo.

Small video of it... [URL] ....

Pictures of turbo area .....

Anything look wrong? I circled that one area but wouldn't know if that's normal or not....

Passat (B5) :: 2002 Jitters Like Turbo Isn't Getting Enough Air Or Choking

Ok my issue is probably a simple and possible easy fix but I need to know what to do. Pretty much you're accelerating more aggressively and the turbo kicks in in between 2000-3100 rpms the car gets the jitters like the turbo isn't getting enough air or choking or something like that, ive been told that it might be a vacuum hose but idk where the turbo is located to begin with let alone where the vacuum hose is.

Also I have '02 passat 1.8T manual

Passat (B6) :: Weird Rolling Noise Coming From The Front Driver Side

Last night on our way home I was on the highway and we get into slow moving traffic around 25-30 MPH I get to heard this tap tap tap tap noise. which was going away when accelerating or braking.. and coming back when leaving the car rolling by itself... I did a bunch of recordings but this is the one you can heard the best... noise actually changes with speed and when turning, but again it goes away if I touch the brakes or the gas...

Noise appears to come from the front driver side.

Passat (B5) :: 2002 / 1.8 Turbo - Fan On Passenger Side Turns On Automatically Upon Starting Car

Noticed the car engine light was on and took it to the autozone to get read by the computer. They said it was probably the cooling sensor. Replaced that part. Still, the light remains. I did notice that the fan on the passengers side turns on automatically upon starting the car. I don't think that is right. I thought it only turned on when the temp rises or the Air conditioner is turned on? Could that be the issue?

Golf V R32 :: Siren Like Noise When Undercarriage Gets Wet Coming From Rear

As described, It presents when the rain is heavy and I splash the undercarriage with big amounts of water, then this very strong siren-like noise comes from rear and underneath the car. Once the car stops or undercarriage is no longer being showered by water from the splashing on the road, it quiets and stops. While present, if I stop the car the noise goes as well.

Some of my searches on google have come to other car forums and they are all seem to be happening on AWD cars, some blame the exhaust is affected by the cooling down effect of the water.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Turbo Noise From 5 To 15 PSI Intermittently?

I have an 02 crew cab SB 7.3L. The best way to I know to describe it is a sorta like a metal ringing noise. It just started this afternoon while pulling a 9k camper. It only does it under load. Boost stays the same and it happens in all ranges from 5psi to 15psi. It is intermittent. It sounds like it it coming from the turbo. I pulled off the boot and could not feel any play on the intake wheel.

After unhooking trailer and taking for a test drive I can not get it to do it again? The turbo was rebuilt about 4 years ago with a wicked wheel but has only seen about 18k miles since the rebuild. A quick look at the boots appear good but didn't get to take them off before going to work. I will try to post video.

Volvo - Xc70 :: Started Making A Loud Siren Noise In Rain

We were driving last weekend in a heavy rain storm when our 2004 XC70 started making a loud siren noise. The noise increased with acceleration. We pulled off the road, turned the car off. When restarted the sound was gone, but then returned again when driving in heavy rain. Any clues as to what is causing this noise and if it needs attention?

Golf IV / Jetta IV :: 2003 - Weird Coolant Leak - Goes Half Gallon Per Mile

i have a 03 gti vr6. 24v 6 speed. it started losing coolant the other day. but the thing is the radiator all the hoses and the water pump(s) are all dry. its fine when its cold, holds coolant just fine. but when it warms up its only fine at idle, so im guessing its some sort of pressure related leak. the car goes through half a gallon every mile or so. only the inner fender on the left side is soaked and the suspension components on that side as well.

Passat (B5) :: 2002 GLX V6 - Gas Leak And Strong Odor

Car: 02 Passat GLX V6 4motion
Mileage: 99k

Just recently bought this car (3 months ago) and I have had lots of issue with it already. I topped off the tank that same week and it started to leak gas right under the gas tank (driver side in front of the rear wheel).

No engine light came on. It leaked for couple of days for about an hour after I park the car then it would stop until I drive again. It did that for couple of days until the gas level went down to 2/3 then it stopped. Since then I stopped topping it off and it hasn't leaked.

However I always smell gas even when its not leaking. When I go around the car the odor comes from right in front of the rear wheel (driver side).

Prior History: This car was rear ended before and fixed up by the prior owner. The seller told me that he had recently replaced the fuel pressure regulator that week.

I took it to the mechanic and had them do a smoke test. They couldn't pin point the leak so they recommended replacing the entire fuel tank for $1800. I walked away and thought I would just keep the fuel level low and keep driving. However the gas smell really bothers me because the car is parked in the garage and the gas odor builds up to unbearable condition.

What could cause this issue? Does this has anything to do with fuel pressure regulator that was replaced? Anything to do with fuel pump because of the rear end accident or loose seal in that area? Do you think it is necessary to replace the whole tank for this?
