I noticed that around the EGR valve. I have oil remains and in some area have marks like oil spraying. Please take a look on the pictures. Do you think that my engine loose the boost pressure because of some gaps into the EGR valve or the reason is something else. Please be informed that I still driving the car with 4,8l average fuel consumption.

I will try to make this test again when the weather condition is better. What I remember on VCDS (ECU => Measurement => Block 4 Value 4) shows 0.0. But I will check again.

Finally I made my rolling test. I can't say that was in the best weather condition. It was a little bit strong side wind. But I made in the both direction and calculate average result. Please take a look over the file let me know what is the result and what is your opinion. Thank you. rolltest_EN_Audi_A2_1.2tdi_BG.xls

Hallo, Ich möchte nochmal nach der Hydraulikpumpen-Demontage und der Reparaturanleitung fragen. Ist es irgendjemand Erfahrung mit diesem Teil?

Thank you very much for instruction and for the file as well. Can you tell me which group is the best to use for the speed measurement with VCDS? May I use the time frame from the VCDS as I will save a log file durring the test? And another question. When I examined the file , inside i saw 18 measurements with different start speed. I have to do it in the same way or only one meassurement 120-0km/h is enough. Enclosed I sent you the English version of this file. Probably it will be helpfull for someone else who doesn't speak German. rolltest_EN.xls

Dear Frends, I still haven't chance to check the car rolling/driving resistance. But I found the right road for this test. Unfotuntely it is about 2 hour driving from me. Can you tell me again from which speed I have to start and to stop 0km/h? Thank you.

I live in the mountain, and in the our area the roads with same altitude is not so much. How do you this will invove to clutch learning process? What have with car that the creep point is come faster and when I drive off and switch from 1 to 2 gear you can feel shake from this quick engagement of the clutch. The same with the car with manual gear box if you pull quick you leg from the clutch pedal.

Good evening, How much the field 1 in group 25 is relevant for good creep point?

Getting more...

Are you sure? I pass more than 30km and didn't see so much difference.

I'm agree what Mankmil propose. I think we should start with way. Can somebody confirm that he did two or three basic setting with modi KNZ and he had the same good result all time? Base on this we can think, why this way is workable? What I inderstood that durring basic setting the gear controler build the basic point and namely open clutch position 4V.

I know this procedure but when is already done. I mean on 25 filed 3 is 0. What I understood in this case this learning process is finnish.

I understood already that is better to flowing not to be stable and knoking. I hope that you are understood me. I want to know which is the clear setup procedure for modified KNZ to don't have this problem after Basic setting procedure. To be honest now after many Basic setting and assembling and disassemblig of the KNZ I succeeded to have flowing KNZ in N gear procedure. But my creep setting procedure isn't pass very well because I have to much creep now. And because I have to repeat this procedure and this is only possible after basic settings. What I have to make to pass this procedure without this knoking effect?

I understood what you mean. But when I have new clutch and I expected it to be worn durring the time, from which value is good to start. And why when I make basic seeting after this the value for open clutch is 4V and I have this knoking problem. if the begining is 1.9 it should calculate 3.9V not 4 volts just to keep this 2V difference.

Wie viel nach den Grundeinstellungen wird die KNZ Voltige, wenn ich in den Anfang 1.6V gesetzt? Ich möchte Ihnen mitteilen, dass ich eine neue Kupplung installiert habe und vor einigen Wochen.

Können Sie mir erklären, warum muss ich 1.6V nicht 1.9V setzen?

Was meinen Sie? Ich habe verstanden, dass die egine dowm ist, weil KNZ aus dem Bereich geht, dank der knorrigen Wirkung. Die Frage ist, warum nach der Grundeinstellung dieser Effekt erscheint und wie kann ich es lösen?

Hallo, Ich werde glücklich sein, wenn Sie Ratschläge über das Problem geben, was ich mit meinem Auto sah. Ich kaufte von MIchael den Hall-Sensor und installiere auf dem Auto. Ich setze die Cluth geschlossene Position auf etwa 1,9V. Aber nach den Grundeinstellungen, wenn ich den Motor auf die Gangstufe N starte, fließt der Kupplungszylinder jetzt und macht Knutscheffekt (siehe Video) und nach einigen Minuten der Motor aus. Könnten Sie mir sagen, ob Vorstellung, warum ist es passiert? Kann ich das lösen? Vielen Dank im Voraus 20170802_220244_001.mp4

Hallo Audi A2 Fans, Ich habe Frage für die Hydraulikpumpe selbst. Ist es möglich, repariert zu werden oder nicht?

What about the tyres. What are your tyres? I tthink for this test they will be important as well.

Hello again, Thank you for the ideas how to check the rolling/driving resistance. The test with 120km/h to 80 km/h I uderstood how to make it. But for the test with gliding from a constant speed until the vehicle stops, from which speed I shoud start. I live in the mountain around 1000m above see level. And around me I can't find straight road 2km long. The maximum what Iknow is 500m long with not so good asphalt road cover. But if I can went to the field area but this is will not happen soon. Please give me your data and in what condition was taken and will try to find the way to repeat the test.

I hope that I will can repeat later to make the comparison. But what have to check on the car concern this problem. May be I have to pass a wheel align test.

I spoke with specialist about oil measurement. He told me that the way as I measured it not the right one. I have to start the negine for 30sec-1min and after I can check the oil level. In this way the oil level is correct so I can say that we can stop to thinking about this problem with fuel into the oil. Lets focus over the slower rises of turbo charger and bigger fuel consumption.

Thank you for your new data. Now I see that you EGR works properly. Regarding the time you reach 3000rpm for 10sec. Which is, I think the correct result. Here is my replies of your questions To summarize your symptoms: -increased fuel consumption ------ Yes 5l/100km -charge pressure rises slower than usual, which should mean lower engine power (or increased rolling / driving resistance) ---Yes, it is, just we have to find what is the reaso for this -fuel deposition into oil ---- This morning I check the oit level when I leave the car all night without oil stick inserted, just to be sure that I have accurate measurement. The oil level is near 8mm up then acceptable high level. Concerning charge pressure i would check the following: -all pressurized air pipes are airtight, including intercooler? - We check the several time and intercooler is well. No any sign or sound which shows leakige problem. -compressor wheel of the turbo does not have too much play? ---- The si comming from MOTO SYSTEM Germany which is specialized for such of service. Before to instal it which check everything what you ask me. -compressor wheel is entirely intact without noticeable wear at the blades? ----- No noticeable wear -youstatist that the turbo is a refurbished one, which is the mechanical adjustment of the bolt. ----we not adjust the bolt because We expet this to be done from the supplier and from our side looks to be OK. To be honest this is the second turbo from MOTO SYSTEM because with the first one considering the problems what I have I return the turbo and ask for another one. Because I think that the problem comes for turbo charger. And the turbo have and 1 year warranty so, I couldn't expect that thay will try sell me turbo which is not works properly. I think that the problem comming from lower engine power and lack with exhaust gas which is not enough quantity to turn turbo wheel. But what is the reason of this and what is connection with high oil level. About increased rolling / driving resistance, do you have idea how to check this?

Please take a look on comparison of EGR between both cars in the same condition. Do you have idea about this difference? Why you specified Exhaust Gas recirculation is always 1000? Are you sure that your EGR is working? I forgot tha mension the I live is 1000m above the sea level. EGR comparison.xlsx
