Thank you for your efforts and time made this test for me. I'm really appreciated it. Please see the file with the comparison what I do with my and your data. You will see that my Audi is going slowly compare with yours and difference is 30% (5sec). And bigger fuel consumption. That's mean I have a problem. I think that I have fuel into the oil. I will know exactly after few days. Do you have experiance with such of problem? What I have to check at first. LOG-AudiA2_12tdi_3rd_kickdown_13052017.xlsx

Thank you. I would like to show you some question form another forum may it is good point for the next step. - Is the cooling liquid clear and clean. Do you need to fill it up. --------It was changed with new one before last week - is the oil rising? Do you smell diesel in it? ---I think is rising.It not possible to check the oil level because that stick is oiled to the small ball. Regarding the smell I'm not sure. - what's the pressure at the oilstick pipe when running? is it blowing, or sucking? -------Blowing - what's the mileage? ----- 135000km but I'm not sure because I'm not the first owner. Regarding the smoke ...no any sign of such a problem. The smell of the exhaus gases there are look clean.

Can you make the same tests on you car and I will compare the result? If it possible check and Basic setting (011) Charge pressure control as well. Thank you in advance.

I compare with my Skoda Roomster 1.9tdi where I can't see such of turbo lag. The diference is comming in trubo working on the same area and altitude. And that my car when I make the test in Basic setting (011) Charge pressure control - the deviation between "active"and "inactive" must be at least 100.0 mbar and my on car when the coolant temperature is 90degr. the deviation is maximum 70mbar. When the car is cold the deviation is 40mbar. When I make the same test on my Skoda whith cold and warm engine that deviation is near 120mbar. Another issue is fuel consumption which for this car is not normal. I never past more of 700 km witn one full tank 30l.

If this test was done with cold engine the result will be worse then with warm engine.

Hello, Here is the data. As you will see acceleration is slowly and turbo delay is big. 3rd_kickdown.bmp LOG-AudiA2_12tdi_3rd_kickdown_13052017.csv

Thank you for your advice, I will make it ASAP.

Hello Everybody, My Audi A2 1.2 tdi. Everything you need to know about it. The turbo is refurbish one of our company specializing about this service. On 1 week life. The VNT is working well and it is not blocked. N75 and N18 work well. Mass air flow sensor and intake manifold pressure / temperature sensor as well. No any visible any leakage from hoses, manifolds and intercoolers. EGR, air filter and fuel filter is new ones. No any alarm on VCDS. Running performance are 130 Tkm. The fuel consumption is 5l / 100km. When I drive the car, the car is in the middle of the road. Only about 2400U / min are then about 2bar of load pressure. In my acquaintance, if he gives at about 1500 rpm full throttle intake manifold pressure and charge pressure about 1 second delayed immediately high. I am grateful for every suggestion.
