That + the situation that you get petrol when you open water tap in that part of the world

I too was wondering how is that possible. But the way its written, the language lured me into believing it .

Anyways, I will surely get the EGR valve checked too.

Vinay did you check with Naveen that if he can clean EGR and Intercooler first ? Intercooler cleaning is straightforward as it is similar to radiator.

I do not know about EGR though , Can experts on this thread comment if EGR cleaning is possible at FNG ? Also should EGR cleaning be done as preventive maintenance ?

Hi Amit,

Naveen already checked and cleaned Intercooler and related plumbing but did not touch the turbo and EGR. I guess opening and cleaning EGR should be a straight forward job?

I'll suggest you open the EGR valve and get it cleaned. Please don't touch the Turbo as it is sensitive mostly, check the plumbing for the Turbo.

I am facing a similar issue with my i20 crdi (the 5 gear one). The car is 4 years old with just 27k on the odo. 6 months back i noticed that the car was belching black smoke on red lights everytime i accelarated hard. The car was rarely used those days( once in a week or so), so i guessed that would be the issue. 2 months back, the issue was becoming worse, black smoke in every 1-4 gears during turbo spools visible in the ORVM. And thick black smoke during sudden revving during idle. Mileage also took a hit and dropped to 10+kms, initialy i was getting around 19+.

Took it to the service centre and they said it might be because of a block in the EGR. They cleaned it and i took it out for a drive, smoke wasnt very visible this time but the FE had improved and was now 19+ again. Was all happy, and then recently the ghost seems to have come back. Belching thick black smoke during accelaration (i never floor the pedal, rarely ever use turbo for the kick of it). I followed my car to see how bad it was, and it is really really bad. Ive never seen a new diesel car emitting this much smoke. And i am very very concerned. Can anyone post your valuable insights on this
???

Fact file.

1. 27000 on the ODO. 4 years old.
2. Cleaned the EGR. Still belching thick black smoke during revving (past 2000rpm)
3. Sedated driving style. Shifts gear at 1800-2000rpm (should i rev more?? )
4. Engine noise on idle has increased. Sounds like my friends 10 year Accent now.

Do you stick to one fuel station to fill Diesel? I suspect Adulteration.Try filling from a different well reputed fuel station (I always prefer BPCL).Also do check the fuel filter and air filter.

Engine noise (read clatter) has increased; black smoke. How long has it been since you cleaned the EGR last?

I can think of:

• Air filter needs a change;
• Fuel filter needs a change and if possible get the fuel tank cleaned;
• Get the MAF cleaned so that fuelling is correct to the engine;
• EGR needs cleaning again;
• Check if all injectors are working!
• Last but not the least try changing the fuel station.

Almost certainly this is a turbocharger related issue. The engine simply isn't getting boost air from the turbo.
It could be connecting hoses, clogged intercooler, blower wheel or turbine caked with dirt/carbon, or whatever.

There is a remote chance that the HP fuel pump metering has gone awry; but this is very unlikely.

.

In that case, would the engine show some signs of sluggishness ?

Asking this for my Getz, which is emitting black smoke under hard acceleration.
Last October, EGR cleaning sorted out this issue and I'm doubting if that could be the culprit again.
Car in total has done 154k kms and approx 14k kms post EGR wash.

Was facing the same issue with my Linea sometime back.
Excessive smoke and lack of power every now and then.
Mechanic suggested to disconnect the EGR, did so, and no more black smoke,and lost power is back as well

Ironically, my car doesn't show any signs of power loss.

After EGR delete, did your mechanic delete the error code as well ?

Hmm, this is confusing. If boost air is not reaching the cylinders there would be a noticeable loss of power/acceleration.
I think you better try what Akshay has suggested.

I am lucky to have last of BSIII Linea MJD.
No Check engine light and error on MID.
BSIV cars have CEL on after disconnecting EGR.

Will clean the EGR and intercooler this weekend and check.
