[Solved] vw / passat / b6 2.0TDI CBAB - High fuel consumption passat b6 2.0 TDI CBAB

Hello,
I have Bassata b6 2.0 TDI CBAB I have a burning problem.
The computer shows fuel consumption of 5.5-6.5L while in reality fuel consumption is about 9-10l / 100km.
I went to a mechanic and examined DPF and it is only 3% full.
The EGR and exhaust gas cooler are removed together with programming from a computer.
Please help . Thanks in advance

Logic suggests that fuel is escaping (leaking). Often at the fuel cooler.

Thanks for the answer, of course, I will check, but unfortunately it doesn't smell of oil anywhere

Unfortunately, my car does not have a fuel cooler because it is on a comon rail. I also noticed that oil is coming.
The mechanic checked the injection molding machine and said it was ok. Help me please because I have no more ideas.

Can anyone help me?

Did you check the flow meter?

Yes, the flow meter has been checked

the mechanic said the flow meter is good

Oh come on. He said? Let him give the parameters. Expected and delivered air mass and not said.

he checked his parameters on the computer and said that they are ok and what should these parameters be ????

The computer gives expectations regarding the revolutions and load and also gives how much air it gets.
But I see that your knowledge is quite small and I suggest changing the mechanics and let another take care of it. No offense mate, but some things are better to give to someone who knows about it.

Is it possible for you to recommend me if you obviously know someone from the Miechów area near Krakow ????

We don't know at what rate the oil arrives. A small amount of oil is usually due to a clogged DPF. The arrival of more oil may indicate damaged rings or a broken piston or pistons caused by the most likely pouring injection.

Under the computer will not show the actual dose. Similarly with DPF. Depends on driving style (city driving, traffic jams) and fuel quality. Please check if it blows strongly from pneumothorax, which will exclude damage to the rings and the piston, however, this is not a reliable control as it can blow through leaking valve seals. Nevertheless, a skilled mechanic will recognize the symptoms by pneumothorax. Another and basic diagnosis is checking compression in cylinders.

ok thanks for the info, when it comes to oil it came about 4mm on 800km

It's a lot. Oil for immediate change because it is diluted.

After testing the pressure in the cylinders, it turned out that the pistons and rings are ok. The mechanic has the same car and 2.0 TDI engine on pump injections with increased power to 160HP and stated after driving my car that it has better acceleration and is stronger. Analysis on the computer showed that the car has 420Nm. Is it possible that in this car chip tuning could be uploaded and therefore it has such combustion and this oil is added (oil in oil)

Everything is possible in diesel. I know the case where the turbine was overclocked and blew as much as it should and the injection was pouring. Despite this, the car had a shoe - until and the patient is an Audi A4 B5 with 1.9 TDI.

How long has your friend got this car? Have recently bought because maybe in the engine there is a doctor instead of oil that good pressure has come out. And with combustion they are probably injections to be replaced.

Car not long ago bought, so I don't know what could have been done before. I changed oil for a new one and made only 1000 km on this oil

So we know something. Probably the injection is pouring. The reasons can be two, either developed atomizer nozzles or broken springs. Please give injections to check or regenerate. There is another third possibility, namely the possibility that the previous owner installed other injections to increase the power. As for chip tuning, I doubt it because it should display relevant software data on the computer.

Hello
The car was made, the reason for such combustion was clogged DPF after its elimination, the combustion is like on a computer and of course the fuel does not get into the oil.
Thanks in advance for your help.
