Passat - Volkswagen :: 2005 - CEL Came On / Faint Exhaust Type Smell
CEL came on. No performance issues or noises coming from the car this time around. I did notice that after parking and killing engine, there is a faint exhaust-type smell though. I took the car to my local Advance Auto Parts and had them hook the car up to their computer for a diagnostic. Two codes came up.
1: P0431, warm-up catalyst efficiency bank 2 below threshold pending
2: P0431, warm-up catalyst efficiency bank 2 below threshold confirmed
The AAP employee didn't have anything to add to the code readouts. I'm concerned that this is a catalytic converter issue, and if that's the case, a repair would likely cost more than I'm willing to put into the car at this point. It has just over 125K miles on it.
Passat (B5) :: Ark Or Some Type Of Electrical Noise / Sparking When Hit The Brake
I was driving home from school today, first nice day in awhile windows open....... and i let my foot off the gas and hit the brake I heard an "ark" or some type of electrical noise. Kinda freaks me out a little, I turned off the music an tried to recreate it a few times, seems like the harder i hit the brakes the louder it is.....goes on for probably 2 secs max. Granted we have had 10 1/2 inches of rain here but still.....

I bought a 01.5 Passat a few months ago and it had developed an exhaust leak. So when I went to check under the car I found it was missing the catalytic converter.
View 4 RepliesPassat (B6) :: Exhaust Sounded Like It Has A Leak - Possible Blown Diverter Valve?
Was cruising on the freeway and all of a sudden my exhaust sounded like it has a leak!!! I gave it some gas and it got louder but the car didn't pull like normal??? No check engine light or anything crazy. I don't think the inter cooler pipes blew off because the engine didn't shut down and I was on cruise mode.
Its sounds like the turbo wants to spool but cant hold boost, can this be the diverter valve leaking or its blown?? I haven't had the chance to check which diverter PN# I have but Im pretty sure its the stock OLD version. I am the 3rd owner. 07 Passat FSi variant with 36K miles.
I hear the 07 FSi are know to have bad or weak Diverters.... I know I needed to go with a stonger TSi Diverter which I hope is the problem here....
Golf/GTI VI :: Loud Hissing Noise - Exhaust Leak?
I feel as though my APR turboback has an exhaust leak.
There is a loud hissing noise that overwhelms the exhaust, turbo and engine noise. What it is. Sounds like a loud hissing when then turbo begins to kick it. Not normal, and it slowly has gotten worse and more noticeable.
I have a feeling its the downpipe, but I can't check it myself. When i give it gas and the hood is open (at a standstill obviously), the engine compartment smells like exhaust fumes.
Could be playing mind games with myself. What do you all think? Any way to surely test and see? I am taking it to dealership on Tuesday to double check.
Camry :: Exhaust Leak - RPM Drop To 500 And Engine Shake Periodically On First Start
I have a 2003 Camry 4 cylinder with an exaust leak. On first morning start after the rpm drop to 500 the engine will shake periodically until I drive about half a mile then all is fine. I cleaned the trottle body at the area of the flap with throttle body cleaner and a tooth brush, and gave the car a tuneup. The problem went away for about 4 days but is back. What can I do to fix this.
View 2 RepliesFord - Explorer :: 2008 - Sound At Start Up At 63K Miles - Exhaust Manifold Leak?
I purchased my 2008 Explorer Ltd about 4 months ago with a 4.6L and 63k miles. I use it for towing a small travel trailer, so I don't put many miles on it. It's got about 66k on it now. According to OASIS, it has had all MFR maintenance performed up to the 60k mark.
In the past two months, it has developed a "sound" on startup. it goes away after about 75 seconds. To me it sounds like a typical exh manifold leak. That "3 cylinder, putt putt putt tractor" sound. There is no apparent affect on performance. It is definitely coming from the area of cyl #1. I have a recording here.
[URL]....
It is the "higher" of the sounds. The lower pulsing/whooshing is just regular engine noise. You can hear the regular engine noise as the camera pans to the back of the car.
What puzzles me is that the exh manifold sound goes away after 75 seconds or so. Holding the tailpipe shut for a bit builds up lots of pressure quickly. Do you think it IS, in fact, an exh manifold leak, and it seals up with thermal expansion as the engine worms up (75 seconds)? Is this a typical issue with the 4.6L
Ford 7.3L Power Stroke (1999-2003) :: Bump / Thump Type Noise When Start From A Dead Stop
For probably years, I have had a bump, thump type noise when I start from a dead stop... say at a red light. I had it in my head, maybe there was that much slop in the drive train... as old truck is over 400,000 miles.
Yesterday, I rebuilt the driver's side axle, bearing,seals, new hub...the works.. I heard that noise again later... and my thoughts were, I did all that work and I'm going to find a lower/upper ball joint is bad, although I did look at them and thought they were fine during the rebuild.
Had my wife get in truck.... and swing wheel back & forth... so maybe I could see what was loose.. or making noise.
I was shocked... just something I never thought of looking at. The u-bolts holding the leaf springs were loose... the whole axle was shifting back and forth on the axle. I've never touched those bolts....
Nissan - Sentra :: Slight Exhaust-type Smell And White Smoke
2000 Nissan Sentra with 105,000 miles. Runs great. All scheduled maintenance from the beginning. Grandma owned until I got a hold of it 2 years ago.
The beginning...
The car has had a slight exhaust-type smell for about a month. I thought it was either an exhaust leak or a small oil leak. I overlooked this as it was running great and I only drive to and from work at a total of 5 miles/day. I was going to be driving it about 20 miles so I figured I should just double check the oil.
Before my drive, I checked the oil and the dipstick said I had absolutely no oil. Backstory: I got my oil changed about 2 months ago and they broke the dipstick. They replaced it with a new one. I drove a few blocks to get oil. I purchased 2 quarts filled it up. I drove off and about a half a block later it started smoking bad. White smoke canvassing the whole street.
I turned around and went back to the auto parts store. I had a guy come out and look at it and he was baffled. The only thing he though was that it had run completely dry and it need more oil. We put 2 more quarts of oil in it (4 now) and it did not register at all on the dip-stick. A small oil leak was discovered coming from the head gasket (that was the smell). Also, there was no milkiness under the oil cap indicating
I decided to drive it back to work to leave it overnight. It smoked like hell and I made it about 4 blocks before it died. I pushed it the rest of the way and it stayed overnight.
The next day, I spoke to a mechanic friend. The only thing he could think of was that the dipstick was not the right size and it wasn’t reading any oil. The oil I put in was extra and the car was burning it off. He suggested I drain out all the oil and put 4 quarts in.
I drained all the oil but only 4 quarts came out. I added 3 quarts of oil and checked it again. Not it was reading about 10 times more oil than what I was supposed to have.
My mechanic friend said to start it up and the oil level should go down. I did start it up and the oil level did go down but it was reading about 5 times more oil than it should have. That is where I am at at this point. Hopefully it isn't a blown head gasket or piston.
Camry :: Strong Exhaust Type Smell In Cabin After Warm Up And Vents On
I just had a blown motor swapped with a used engine with around 50,000 on it in my 2002 Toyota Camry LE 4 cyl.
After driving the car enough to warm up I turned the vent on and in comes a fairly strong exhaust type smell.
I have driven the car for a little over an hour since the motor swap.
The car is driving fine with plenty of power and no sputtering or rough idling.
I just called my mechanic and he seems to think it is due to the oil that is present on/around the motor/exhaust from the swap that is burning off.
Golf IV R32 :: Distinct Exhaust Leak Noise Coming From Manifold Area
Finally got the car started after over a year of acquiring parts and labor. Cylinder 5&6 had misfires due to faulty injector harnesses. That issue has resolved. But I am getting a pretty distinct exhaust leak noise coming from the manifold area and i cannot figure out where it is coming from. We smoke tested it and still can't find the leak.
Things we checked:
-Head to manifold (all nuts tight)
-Manifold to turbo (all nuts tight)
-Turbo to downpipe (2 vbands both tight)
-Wastegate (2bolt manifold to adapter tight and vband adapter to wastgate tight)
-(2) O2 sensor plugs on the maniold (tight)
-All turbo hardware (tight)
-manifold and downpipe have no cracks

View 8 RepliesFord F-150 (2004-2008) :: 2007 - Whirring / Bearing Type Noise On First Start Up When Cold And Truck Sits Overnight
Ok, so my 2007 F150 Lariat super crew cab has been at the dealership for a week now with them claiming that a part is on back order. How hard is it for them to get in a right front axle?? Granted, it was in there for other stuff too (which they can not give me a straight answer on if they fixed or not cause they are claiming the technician hasn't done the write up on it yet). My main concern is that they are screwing me around or that something happened to my truck. I am planning on stopping by there on Wed. morning after I get out of work.
Are these trucks known for bad front axles or was there some kind of a big recall on them?
Other things it went in for was the radio having the CD's cycle through when you first start up the truck, but does not happen like that all the time. Black plastic driver side front door hinge is cracked exposing the metal reinforcing part. Whirring/bearing type noise when you first start up the truck when it is cold and sits overnight (which they claim they can't hear yet waited to bring the truck inside and check it out at 3PM when they had the truck overnight from the night before when I dropped it off.) and the front driveshaft not fully disengaging when the truck is in 2wd. Almost seems like the vacuum locking hubs are still engaged.
Ford F-150 (2009-2014) :: Ticking Sound During Cold Start Engine Warm Up - Exhaust Leak
5.0 coyote exhaust leak .. Since the cold weather has arrived i have noticed a new noise. During cold start engine warm up I hear a nice little tick-tick-tick which sounds to me like an exhaust leak. Is this a common problem? I have just over 58,000 miles would this be covered under powertrain or do they have some nice exclusions for exhaust?

View 14 RepliesFord 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.
