Bad blend AIR/ FUEL

[firesun]

I also do not want to watch Videos of a broken Car It is a waste of time and no alternative to making measurements.

It was for me to show how gov is exagerating!
No matter forget it then

I have not reread the 100 posts in this thread but have you changed the DPF? My first reaction to the video is that it is a cracked DPF internals allowing soot to go through

 

[firesun]

I am not equipied with DPF!
I just changed my catalyst... Maybe it is not jointed as well as it should
But do you think that my problem can be that circuit in the pic i joined?

8E0906627C TRANSDUCER OF PRESSURE

 

[firesun]

i mean the hoses of this

Maybe you will never pass the test given no DPF and the age of the car and engine ? Do the same test standards apply to this car as cars fitted with DPF ? Non DPF diesels will smoke especially as the injectors get older and worn and fouled

Oh what a nice question!
I will ask technical control and get back to you!
I will pass this test by hook or crook!
I have an AUDI A4 B5 and its tests are very very good!
It has no DPF!

It's a 2008 model. Were they required to have DPFs?

ETA: A bit of searching on the web indicates the earliest they would have been mandatory was the in summer of 2009 for Euro5 cars, and that they were never fitted to VW's 1.9L TDIs...?

I guess no because my motor don't have
It is a 2007 year millesim 2008

If it's the injectors case why VCDS can't say me this?

VCDS can only tell you what the car knows.

VCDS can only tell you what the car knows.

Please remember that VCDS (any diagnostic machine) plugs into a 16 Pin DLC. It can only read what that DLC is writing which in turn is limited by the sensors fitted. That then is only processed data not Raw or Organic.

Just like food - Processed will hurt you - Organic will Preserve you !!

Surely as a Robotics and Automation Technician you will / should already know that ?

I am technician working on robotics and automatas

Let me guide you. Aircraft Technicians only specialise in one discipline ! Easy !!

Unlike Proper Automotive Technicians. We do it all and we do it well !!


Automation and Robotics which you boast about is childs play. What do you know about the tech in a modern car ? I guess you would be ok with Electric Windows, Seats, Mirrors.

A Convertible Folding Roof will quite likely destroy you !!

You need a reality check !


I could adapt to your job in a year, You could not adapt to mine in 10 Years !!

Injector spray patterns are critical to get good combustion in a diesel. As injectors wear and foul the spray pattern is affected leading to increased smoking due to poor combustion. This mechanical wear in an injector cannot be detected by the car until the injector fails badly and even then it will be an indirect indication via things like fuel supply pressures or mileage measurements or exhaust catalyst or DPF issues depending on the car and the sensors it has.

Hello brother!
Thank you for your reply!
Yes i really agree with you! First i thought when VCDS show me injection values next to zero, that they were healthy!
With reflexion, time and a lot of help from Dr Sheldon and Mr Uwe that i can't thank them enough, i understood when i looked up my dashboard again and saw 280 000 kms that injectors have to changed a long time ago!
I have ordered 4 BOSCH injectors AUDI remanufactured of course...
i will receive them next week and mount them asap!
After this i will surely have better results concerning my problem!
Get you back of that results at the same time.
Thank you

Hey Dr Sheldon !
How are you today?
I won't say no to you anymore so i will learn from you even i think it's mad or no use to do this instead of that! LOL
I have althought my proper opinion of the evolution of the rapport between progress in general and human kind !
I won't expose that point of you that you couldn't disguise!
if you really want to take to my opinion just let me know and we will have PM so we can better exchange! Just ask!
Thank you again Regards

No thank you ! I have a full and varied life of my own !

Look closely at a PD injector ! It has thousands of drillings to disperse / atomise the fuel !

 

[firesun]

Hello Dr Sheldon!
Yes they have almost 280 000 kms and i rarely clean them with some chemical solutions so i guess the are in addition to be dirty worn!
So when i receive the new ones i will take a look to them and take some pics too to show you the spectacle.
Any more advices to when i will change my injectors? I am all listening to your preciouses advices...
Thank you!

Hello all,

Here are the model of injectors i received yesterday!

 

[firesun]

Hello Dr Sheldon,
Tomorrow is the D day!
I have a rdv to change my injectors at the mechanical.
I decided to change also the in parallel of the injectors the double temperature sensor (Double capteur de temperature - 059919501A).
Can you confirm with me that it have an impact with smokes if this sensor is faulty?

 

[firesun]

Hello all!
Today i wanted to calibrate the throttle body!
I found that channel 60 or 98 on VCDS was marked error!
Can you tell me if it is normal or not?
