Nochmals, tut mir leid aber schwarzer Rauch beim Kaltstart

[Math]

Sehe bild bitte, bisschen gas geben mit kaltstart...fast schon ofters erwähnt

abder trotzdem stelle ich die frage noch mal.....

seht mehr aus wie Öl anstelle von Ruß...oder Ruß  und Kondensation

 miteinander vermischt?

Is das normal...?

Kondenswasser mit Ruß vermischt - einfach mal gescheit warm fahren und nochmal testen.... Bin mir fast sicher, dass das dann weg ist.... Muss ja nicht immer direkt vom Schlimmsten ausgehen.

Wie alt sind die PDE?

Wie alt ist der Turbo?

Steuerzeiten im Soll?

Ölverbrauch?

 

Fährt der Wagen Kurzstrecke oder Langstrecke? Ist die Beobachtung von dem vorherigen Fahrtprofil abhängig?

Wenn du kein Ölverbrauch hast, kann es sein, dass unverbrannter Diesel sich mit Ruß vermischt bei Kurzstreckenverkehr ansammelt und dann sowas rauswirft.

fine, so ask the question in english anyway. We need more information.

[Math]

bret, what info?

I dont get it why this engine smokes heavily at cold start....I wonder if all 3 cyl.  1.4 TDI have this behaviour?

I dont know nothing concerning history PD, Turbo etc. 

I dont know of any vacuum leaks or bad components....changed filters etc. No specific error codes....no MIL light..nothing just black smoke whit little higher rev....  

For the rest no problems, runs just fine....(though I think I noticed some change when disconnecting Air Mass Meter, but probably im seeing ghosts)

Im kind a enviroment freak and this is quite annoying..i already told im looking for other car, but this diesel affair makes thing hopeless to sell...

(now they probably tell me to go to English forum..)

So it is still the Nov 19th Problem at engine start? Just the splatter on the ground, or visible smoke behind the car? No more of this once it's running for a little while?

[Romulus]

Good that you are on speaking terms with us again. We are a very helpful bunch of enthousiastics, but the answers we can give are as good as the information we get.

 

We are talking about an AMF engine, not BHC engine, right?

How much did the car drive until now (km-stand)?

What do you know about service history?

How old are the fuel filter and air filter?

How old are the unit injectors? Were they ever replaced?

How old is the turbo? Has it ever been replaced?

Is the timing of the engine all right?

Does it consume notable amounts of oil?

Are there any DTC, failure codes to be read using OBDII?

 

Do you drive short or long distances? Is the effect depending on how you used the car before?

Both splatter and visible smoke af engine start, seems thé lower outside temperature, thé more.

When engine hot, nomore.

Read the reported engine temperature at cold start and compare with the outside temperature. Should be fairly close to each other. If not, change the green temperature sensor:

How Read the reported engine temperature at cold start ? OBD?

Yes, for instance using Torque. 

 

How long did you own the car now? How many kilometers driven since?

[McFly]

At cold start: Black smoke, grey smoke, or white smoke?

The splatter is very likely due to only short operation intervalls accumulating condensate in the exhaust mixed with grime. Grime is always there, if it becomes worrisome you could think about a leaking exhaust return valve. Something, that reduces oxygen while still maintaining manifold pressure. Or PDEs that are wearing out due to age, i.e. that don't spray as fine as they used to do.

Smoke Mixture of all...

Yeah all can be so true, i don't plan however on checking or replacement PDE.

Oh u Mean leaking EGR valve? Thought exhaust valve.

My guess would be to rich Mixture...due to leaking injectors but that also a wild guess

[McFly]

So it is only a puff of smoke after startup? Like after a few seconds it's back to normal? That would indicate that either oil or fuel is accumulating in the engine while parked. That's typically leaking PDEs or some oil from leaking valve stem seals. I'd figure PDEs are more likely. If it would be white smoke it could also be coolant. Your coolant is clear and free of oil I assume w/o any loss?

 

But, if you don't want to investigate and fix it you'll have to live with it.

Not for sure, but all indications are pointing that way unless somebody else here comes up with a simpler explanation. 

Do you have VCDS or similar? At least you could check on the PDE correction values to keep the idle stable. That would give a feeling if one is completely off. But I don't know if that would also indicate a probably leaking one...

[Romulus]

Simple start: temperature sensor.

If not that, probably PDE.

[Romulus]

There are two. Read the article and the wiki.

[Artur]

It's a double temperature sensor. One for the dashboard and the other one for the engine control unit. The latter is the important one and delivers wrong numbers maybe. So you have to check.

Nope. For the system it's still working. It doesn't know the sensor is lying. There seems to be no plausibility check.

Faulty sensor doesnt make sense to me,  then engine would be smoking all of the time if computer it thinks engine is to cold, to rich mixture and it does not, only at engine start it smokes.

Anyway I just to a look and swapped it with another working sensor (how do they manage to put that thing where it sits....so little working space like I said hate working on this engine)...
but no result like I thought so...and broke the electric connector on top...now hopefully it still connects properly...

I notice after some time smoke gets less...so like McFly my diagnosis are faulty PDE, fuel is accumulating in the engine, and that I aint gonna fix...

Still thing I find little bit strange that when I give a little gas it smokes heavily, at idle less...but that is probably due to the fact that it injects more fuel at higher rev and together with the fuel already in the engine its much more fuel...or?

 

Many thanks you all...(now can I still ask other things in English if i want to...:-))

that depends. if the consumption is "too high", then it's possible that it's just because too much fuel is being burned... and then you get nice black smoke...

Diesel, no mixture, just injection of given quantity of fuel at a given moment. Too cold measured temperature would give hard running engine and higher idle rpm.

 

As said, symptoms could relate to the temperature sensor, which is a cheap and "easy" fix. Now that you excluded this one, you know what you might be up to. BTW, just a thought: I think that 206Tkm is rather young for serious engine trouble and fairly low for a 16+ years old diesel car. Are you sure about the mileage?
