Passat (B6) :: Loss Of Power / Jerking And Black Smoke
Jan 10, 2013
Vehicle details : PASSAT 2.0 TDI 170 BHP DSG - 2007 ... 160KM
Problem:-
>>RPM doesn't climb as it should and esp in the run up to 3 gear and the DSG up shifts too quickly 4th and 5th
>>Loss of power. Pressing the gas pedal during all this leads to lots of black smoke and jerking but eventually the car picks up rpm and speed. Am I stuck in limp-home mode here?
>> No CEL light (yet)
The problem becomes very prominent when the engine warms up fully. Its drivable before that. Driving it in Sports mode is the only saving grace. Note that the car it is nothing like how it should be in sports mode, but feels better. I can hear the turbo whistle only when the engine is cold.
Initially, the Engine mounts were thought to be the culprit (for jerking and then ECU reducing power) and then later the EGR value unit (jerking/pinking and power loss).
Work done so far :
1. Original VW Timing Belk Kit (incl water pump) - September 2012
2. Engine Mounts changed - - September 2012
3. Has been plugged into VAG Diagnostic software and an intermittent error was detected for EGR.So, EGR valve control unit was changed - late December 2012
4. Engine Oil (5W-30, fully Synth) and filter changed three time in space of last 10K KMs after I bought the car in September 2012. This is something I wanted to get done anyway to flush the engine
5. Used injector cleaning additives couple of times -December 2012
6. ECU (error-code) reset procedure, just a couple of days ago. This actually seemed to remove some of the jerking and loss of power, but it appears to be coming back now.
7. Transmission reset - yesterday . Did this anyway although the DSG seems to be fine, no problems with the gear shifts

I have had a problem where truck would start jerking and sputtering in a certain town at low speeds. Today it happened in a new place. Barely got it to start back up. Was running rough after the puff of black smoke. Its stranded at a gas station. Recently replaced my sending unit. Was running good. Clean gas tank. Fuel lines tight. Where should I begin? I have an ICP sensor in the glove box. Truck wouldn't start.

I have a Santa fe 2002 crd 2.0 4x4 and recently had a lot of black smoke and a loss of power when driving, it starts fine but when revving it blows black smoke from exhaust and has no power to pull away, been told its possible turbo problem or fuel problem.

Initially I used to get cutting out of the engine randomly whilst driving which everyone believes is linked to an ECU issue i believe...I added some reddex fuel cleaner and that seemed to clear the problem up for myself which is a diesel 2.2 ...
However I was beginning to have starting issues where i would need to pump the gas to get the car started...I changed the battery and the glow plugs and yet i was still having issues. I had the air intake and filter looked a diagnostic test run both showing no issues and then one day I was driving and suddenly i got a huge loss of power and black smoke out of the exhaust....Seriously i had no grunt and i was a hazard to cars behind me....!!!! It was weird how first thing in the morning it seemed fine but later in the day i was getting this problem over and over again and eventually the car wouldnt start without a jump from another vehicle..
Any how i took it to various garages but in the end i took it to Rockar Hyundai at Dartford (i cannot recommend enough) but simply all they did was look at the fuel filter and saw that one of the injectors were faulty...After changing this the problem still occurred but again only when the car was warm...They then looked at the pipes leading to the injector that was faulty and then found that there was a crack/split in it and obviously when cold it was sealed but when warm was opening and i believe letting in air.... Anyhow they have changed that and the car feels great and no issues...

Truck has been running like a champ the entire time I had it. Took it in yesterday for an oil change. They also changed the fuel and air filters.
Drove off the lot and noticed some loss of power. This morning truck still feels sluggish but it is also blowing out black smoke pretty much every time I touch the gas pedal. I am even being super gentle with it. Starting from a stop, I hit 1500rpm and it's blowing thick black smoke as if I was flooring it. Same thing while rolling to get a bit more speed to pass.

Today I was riding along and all of a sudden I noticed a loss of power. I look in the rear view mirror and get into the pedal and a lot of black smoke. When I get to where I'm going and stop I noticed the idol was a little loopy. I never saw a check engine light. I have the Edge insight. I had two codes. P1000 OBD System readiness test not complete. P2290 ICP TO LOW.
When I would reset the codes the P1000 came back instantly every time. I parked the truck for about an hour. When I started it back up everything was normal. The power was back and no smoke. This happened two more times throughout the day. I have heard people describe a sticking EGR Valve causing these symptoms. Is that where I should start looking or is the ICP the culprit or something else?

So my 1987 Econoline Van was running fine until recently we noticed loss of power going up the slightest of hills and it will only hit 55 max with gas to the floor. Its shooting out black smoke and also dying when we stop. We are getting very poor fuel economy as well.
We got a tuneup, oil change, new air filter, etc. We also had a few electrical issues due to a short we thought we had fixed completely... So I'm wondering if it could be the timing? Cause it'll idle low, then high, then bog down and lose power...
Also was thinking maybe bad fuel pressure regulator or fuel pump....but how would I check this? And since we did experience a short, could we have blown a sensor too?

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 ?

I have a serious issue with my 2004 F250 6.0. Pulling a trailer something under the hood sounded like an explosion and lost power and boost. The truck started blowing black smoke from the tail pipe. I could see no psychical damage to anything under the hood. There was absolutely no power but managed to cripple home. What happen.

2001 1.8T ... using oil 500ml/100km
- Blowing smoke-intermittent
- Power loss-intermittent
Some jelly white stuff in oil may not be related... Service techs looking at turbo....

So the wife was following me home yesterday and I got on it at a stop light. She said that I had a puff of black smoke come out when I shifted gears. The car is a 2006 2.0 m/t w/ about 60,000 miles. Never had the oil light comes on but dipstick is always dryer than it should be although dealer always says I'm fine. Today my brother-in-law was following me and I told him to watch. He said he never saw a puff when I was shifting but that once at idle he saw a slight black smoke. Car is cpo for another year or about 13,000 miles so it's not an immediate issue but if it's a problem I want it fixed before warranty expires. Is this just normal?

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.

While I was pulling off and boost started to build up I heard a loud "pop' ( sounds like when you disconnected the hose from an air compressor ). After this happen the car doesn't wanna idle or rev up past 2k rpm'ish. I was getting a ton of black smoke from the exhaust and had a very heavy scent of gas. Does this sound like a blown turbo symptoms?

I have a 2003 with 150k miles. My 6.0 has black smoke and can barely crawl up a hill. Dealership is 30 days out for an appt. Air filter, oil change, alternator, and batteries are new. I removed the EGR valve and cleaned, but the valve seat is not perfect. I can see 20 to 30 mil gap around half of the seat. Is this ok or will that little gap cause this?
Hoses all look good. No alarm lights. I have no diagnostic tool but I can use a meter well. It did have an airbag light but I found the fuse missing and replaced it. The air filter alarm switch fell apart but I bypassed it till I get new part. No alarm lights now.

So I am not sure exactly what is going on with my truck. It is a 2004 F250 has a 6.0 L. Sometimes when I take off from a stop the truck has no power and blows some black smoke. Then the turbo kicks in and all is fine. It comes and goes when it pleases no matter the temperature. What started happening is when I drive it a steady pace on the highway sometimes the turbo gets quieter and louder and quieter and louder sometimes when it gets quieter I see a little bit of black coming out of the tailpipe. Sometimes it doesn't do it at all. Also sometimes when I let off the gas the truck sounds like it's trying to laugh at me like a wastegate is fluttering.

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

Short version is that I just did the EBPV delete with new pedestal and turbo exhaust outlet and put a new turbo middle cartridge in as mine had blown a seal and possibly broken the shaft. Once I got it all put together, I took it for a test drive and it was building 20PSI like it used to but I didn't have the accumulator and turbo mated up fully so I had a leak there.
I corrected that and now don't get any boost until I get to about 2500RPM and then it only builds to about 10PSI. I've double and triple checked all my connections, boots, etc. and everything is tight on the intake, intercooler, up-pipes and collector, exhaust and the spider, I can't see or feel any problems there. I tried disconnecting the MAP sensor and it might be a little better but not even close to normal.
Tried disconnecting the red line from the wastegate and plugging it with no difference. I'm stuck, and frustrated. I do have AE, watching the MGP looks like the MAP sensor is working. I feel like I'm overlooking something simple but I just can't figure out what it is...

I have an Excursion with 220k miles. I've owned the truck for 6+ years and had very few problems. I change my own oil and fuel filters, but beyond that I know next to nothing about the diesel motor. I do run a DP Tuner with the standard 80 hp program. And a 4" exhaust. Everything else is stock. I do keep it plugged it for the oil heater and the battery tender just about all the time now.
This latest issue started yesterday morning when my wife jumped in a cool truck to take the kids to the dentist (not warmed up but still 55 degrees ambient). A few miles down the road (35 mph max) the motor began stumbling and rocking and black smoke coming from the exhaust with reduced power. She pulled off and kept it running (very rough and rocking) and put it in park for a minute. When she put back in drive, it shifted heavily but the power was normal so she went on her way without any problems. The only report I got sounded like the motor was just cold and rough, so I thought nothing more of it.
Yesterday evening we drove it about 70 miles on the highway (72 mph max) with no issue at all, but when we continued on surface streets toward our destination (50 mph max) it did the same thing, but would not settle back down. I kid you not that it went through gallons of fuel the last 12 miles or so, just dumping black smoke out the exhaust. It felt to me like we were running 1/2 the motor, like the plugs weren't lit. Very rough and rocking and very little power (comparatively, at least). I had to switch to manually shifting the trans to get going and the shifts were much rougher than usual. Idle was low and rough but it never stalled. Behind me there was a huge smoke screen this entire time.
We made it to our destination and parked it. Did our thing and after 5 hours went out with finger crossed. Started right up and ran perfectly the entire 91 miles home. No motor or trans issues at all. Currently running 10/40 synthetic oil that I just changed about 2000 miles ago. Oil level is perfect. 3/4 tank of fuel with standard level of Diesel Kleen added. Fuel filter is less than 10k miles old. Temps yesterday were 65-70 on the drive down and 50-55 on the way back.
I jiggled all sorts of connectors this morning and didn't find anything loose.
