Passat (B6) :: 2008 - Blowing Out Black Smoke On Hard Acceleration?
May 1, 2008
Ok so the wife and I were heading home, she was in her 2.0t sedan, I was in my 3.6 4motion wagon. I got stuck behind a slow driver on the highway (doing 50 in a 70 mph zone) so I get in the passing lane and I floor it to pass him. When I get home, my wife tells me she saw a good amount of black/blue smoke coming out my tail pipes when I went to pass the other driver. This is on a engine with 2400 miles.
I take a look, and the chrome exhaust tips I had installed not long ago are now all black, covered in a oily thick residue. These same exhaust tips were on my previous 07 3.6 4motion wagon for 10k miles and was still shiny when I took them off. but after about 1k miles on the 08, they are now all black. I check the oil and it still reads full.
So what could this black smoke and this oily residue on the exhaust tips be caused by? should I be concerned? Engine runs fine with the exception of sometimes stalling when trying to start it after a short stop. (VAG-COM doesn't show any error codes logged.

My 2006 F-250 (6.0 Diesel) started blowing black smoke under acceleration yesterday. It has 181k miles on it now. No loss of power, no rough idle, no smoke unless there's a load on the engine like accelerating, but then it doesn't matter if it's 1500 or 3000RPM, just the higher the RPM the more smoke it blows from the exhaust, dark black.
The truck has ARP headstuds, no programmer. Replaced both batteries and the A/C system about 2 weeks ago. About 3000 miles ago it got new glow plugs & harnesses, new alternator, all fluids changed, new aftermarket EGR cooler, new EGR valve, new turbo & actuator, new EBP sensor, new HPOP incl pipes and IPR.
Trucks starts up just fine, runs normal, just yesterday going down the Freeway about 65mph I noticed it started smoking black going up a hill, then smoke went away going downhill... Now every time I accelerate it's smoking black. Taking off from a stop sign it made a little puff of white smoke then went back to black smoke, but that only happened once.
Where I should start looking? No codes so far. But I have an AutoXRay EZ-Scan 6000, what sensors do I need to look at?

I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.

Well my problem went from bad to worse. My 05 started running rough at idle, then smoothed out a bit but started smoking on acceleration a little. At this point it felt like it had more power than ever before and even ran smoother running up to 3k RPM before shifting (manual transmission). But now it's smoking so bad, I can't really drive it. It's smoking white or gray at idle but blowing black smoke on acceleration. I had a cylinder 5 contribution code but with the amount of smoke it's hard to believe only one injector is a problem. I pulled the EGR valve and it doesn't look stuck open but I'm going to replace it anyway.

I've been told by friends driving behind me that every time I accelerate I emit a plume of black smoke followed by a stream of black colored "water". I checked today by having the wife rev the engine to 4.5k...sure enough, black water shoots out of my exhaust, probably 3 oz. I also see a black puff of smoke which I assume is more normal than the water. Is this commonplace ?

6.0. 115,000 miles. Everything stock, except bully dog intake filter.
I replaced the FICM recently, with one that I bought from the guy who makes those cool You Tube videos, Diesel Tech Ron. I also replaced the EGR valve. I also replaced the intercooler boots on the hot side. I cleaned the intercooler pipes. I cleaned the intake filter as well. I'm still blowing out black smoke, if I floor it when I need to pass someone.
Follow up question: I bought those boots from Riff Raff Diesel and I bought new clamps, too. I'm not sure if I installed correctly. It's already blown one off (it blew the top of the intercooler pipe off, by the turbo, but the boot stays on the turbo) and I put it back on and tightened it all the way down, and I've had to re-adjust 2 times, now, since it acts like it still wants to slip off. Do I simply have the other ones misaligned???

Driving home 2003 6.0 started blowing a ton of black smoke, cars wouldn't get behind me. Found an exhaust leak on the driver side up y pipe. Would that cause this much smoke? 2 codes were 0284 and 0281, I replaced those injectors about 10k ago, at the same time replaced turbo, hpop, egr valve and cooler delete, and new oil cooler.

Found a 2004 Ex, Eddie Bauer edition says it has injector issues, blowing black smoke........ It is apart cause he thought it was the EGR. Has 245,000 on the clock. If the body is super clean I'll give him a offer, it's going to get a motor either way and I'll have my Ex back.............I really miss that truck!

I bought a 2003 Vw Gti 1.8t ... What to do or look for when something goes wrong . About a two months after driving it, it won't idle and it shuts off while in Neutral . I've done my research and i believe he didn't install the BOV in right, only bc it is not recirculates the air. Make sense? Is there ANYTHING i can do so it will run better and idle?

Ok I have a 2004 f250 6.0L, has 104k on it. A little back story... truck was running well when I started to get surging on takeoff and it was blowing black smoke when it surged. After it hit 1600 rpm it would blow out and run normal. So did some research and found it could be the FCIM, I have the 4 pin and tested it and had 48.5v so it tested good. Did some more research and found symptoms leading towards the ICP so I replaced that and the ICR also.
Upon doing this my surging issue cleared up but now I'm getting a miss around 1200 + rpm weather it's in park Reving it or driving, but it is not throwing any codes, I did check with my code reader. I have also changed both fuel filters and have the EBP sensor on order as I hear they can be troublesome. My question is what should I do next or look at? I was trying to avoid the dealer so I can learn more about the truck in diagnosis.

I have just replaced the EGR cooler, Oil Cooler, professional turbo reconditioning, both dummy plug's and stand-pipe's, blue spring, fuel filters, oil changed, cleaned the EGR valve and intake manifold. I am in the process of doing a coolant flush when my issue occurred. I was on the road for about 10 minutes when I lost power and started blowing black smoke. I have normal power till about 45 mph then nothing. I can baby the truck up to 55-60 and then nothing and the whole time blowing black smoke.
I stomp on the pedal with no power. I hear the whine of the turbo. The truck idles and sounds fine. My SCT showed my oil and coolant temps within 15 degrees. I opened the hood and saw soot all over the top of the engine from the compressor to the EGR valve and all in the valley from valve cover to valve cover; but more so on the driver side to FICM. I obviously didn't connect something properly. I am just about to remove the intake manifold and reinstall, but before I do just wanted some input.

I have a 06 6.0 Powerstroke 6 Speed every time I get on it or even try to get going I have no power and I have pure black smoke blowing out the exhaust somebody told me to change the fuel filters which I did which they were pretty nasty then after I did that I seem to still have the same problem so then they told me to check the EGR valve put injector cleaner in it to clean the injectors which I have not done a gr or injector cleaner yet just wanted to know, what it could be or what I can do to prevent the black smoke I have no power either...

I have a 2003 F250CC 7.3 with 200,000 miles on it. I just purchased this truck about a month ago. My question is it blows black smoke. A little at idle but mostly when you give it any pedal. I have replaced all of the injector o rings and that didn't make a difference. Then I had it tested and it failed a CCT test on #2 cylinder. I have an injector to put in it, but am curious to find out if 1 bad injector would be enough to make it smoke all the time. I keep getting P1211 ICP pressure above desired. I had a friend of mine who used to work at a ford garage take a look at it with his computer and he said that everything looks good other than the CCT test.

After running perfectly fine all day my truck will seem to bog down and when I press the accelerator the reaction is extremely delayed and tons of black smoke will come out of the tail pipe before the truck actually gains power and takes off. The check engine light has been coming on but will turn itself off after the truck has been shutdown a few times....

So I've been having issues with starting my truck lately. It was really hard to turn over, would start really hard when it did and would blow some black smoke. Turns out my starter was bad so I replaced it with a DB Electric high torque starter. Now it starts up great... for the most part.
I'm still having some black smoke when it's a cold start and/or I have the key set to "On" to warm the glow plugs for a few seconds. It's almost like the starter is turning over the engine, but for the first few turns it sounds empty or hollow (at least that's the best way I can describe it). After the first turns it will sound normal how it's supposed to and will fire up shortly after but with some black smoke.
If my car is already warm it cranks right up without any smoke unless I have the key set to "On" for a few seconds to warm the glow plugs like I said earlier. Pretty much if I warm the glow plugs it makes it harder to start up for some odd reason.
What might cause this or how to fix it? Maybe some of my glow plugs are going bad, or possibly my IDM? I used to have the P1670 code by itself, however, that went away when I replaced the starter. I also just replaced my camshaft position sensor just to be sure it wasn't going bad. I've also been having some boost pressure leaks if that's relevant at all.

I was towing my camper uphill and my 03 6.0 started missing and blowing black kid smoke. Next thing I know I hear a loud pop and steam is coming from under the hood and the truck dies. I pull over and discover the degas lid is stuck on and the bottle came apart at the the seam and the truck will not start. 6.0 with 120k miles

Was hauling a bobcat this AM and noticed something odd in my rear view. Under steady accelleration (either light or heavy foot pedal pressure - steady either way), the exhaust would puff out sporadic extreme dark clouds of smoke. The puffs weren't fast like every cylinder rotation.. but every second or so.. puff of very thick black smoke mixed in with the expected black smoke we see.
Truck has 350k miles with regular oil changes. Year ago someone hooked the injectors up to the computer software (buzz test) and all of them checked out to be in very good condition.
The same tech pointed out some dark blowby at the uppipe on the back of the engine. Other than that the truck is in pretty good condition for its age. What could the sporadic very thick/dark puffs of black smoke indicate?

Our 2008 Acura MDX started blowing black stuff through a/c system (driver and passenger sides). When I picked up a piece of it and crushed it in my hand, it would disintegrate into almost a powder-like substance.
We took it to the Acura Dealer and according to them interior filter and a/c vent look fine and they would have to take the whole dashboard apart to see if there is a problem. What it could be? It's not affecting the performance of the car and the AC seems to function just fine. This black net-like particles started last summer.
