1.9 TDI bsw Fabia - lack of power

[IsaacMor]

Hello guys i'm new to this forum since I bought 2 month ago a 2010 Fabia 1.9 tdi with 300K KM. 

The car is well maintained full service history at Skoda dealer till this day.

 

When I bought the car it drove like a train uphills and everything I have put it through.

The fuel cons was 7.5L/100KM in the highway and 8L/100KM in the city which it should be more economical...

The real deal was about 3 weeks ago when i drove the car and it felt like a bit more lazy, first and second gears pulls nice, but in 3rd gear the lack of power can be felt better, 4th gear from low rpm (1500-1800) it takes hard time to accelerate even from 2000 rpm it doesn't pulls like it used to be...  The same goes for the 5th gear, can't drive  more than 120km/h on uphills which previously i could drive there 150-160 easy. 

 

As I said the car has 300K km on the clock, fully serviced. When I bought it changed the fuel filter new 5w40 505.01 oil, oil filter. 

the car starts well and doesn't have any black smoke. I went to a guy I know who is servicing VW group car, checked the car with VCDS there were no codes, he took it to a spin, told me to change the mass air sensor. Changed it the day after the nothing has changed. He also check the injectors - they are fine, boost pressure sensor 3rd gear full load goes up to 2150 mbr which is good.

 

I checked all the vacuum lines, there are no leaks, checked the EGR which it looks pretty clean( the Previous owned changed it 70k km ago), the upper turbo hoses are well connected, no leaks, checked the turbo actuator it moves freely.

 

WHAT IS THE NEXT STEP? can the vacuum solenoid block can be faulty?  there is oil around the turbo inlet hose is that any problem? What can cause this kind of problem that the car isnt pulling well in low revs and cant get the power above 2k rpm in 4th and 5th gears. 

Is the fuel cons normal??

 

Thanks you for your help guys!!!

Hi buddy! Any updates on this? Have you managed to fix it?

[IsaacMor]

Still haven't, the car drives fine but lacks of power, the VCDS doesn't show any problems of signs of something wrong, this is totally wired. 

Some guy that seem to understand something told to me check the injectors by removing them(on VCDS the injectors seem to work just fine) .

I also think about changing the vacuum solenoid block, not a new one but a well working one, if it works bingo if not to the next... 

 

What about you what's your problem with your mighty 1.9 tdi?

That's a lot of oil leakage, it suggests the turbo is very worn and the intercooler is probably full of oil as well, I wouldn't be surprised if the impeller is showing signs of wear and there's excessive end play in the shaft. Take off the TIP and have a look.

That turbo looks screwed with that amount of oil also 1.1 bar is pretty low I’d say.
