    Hello, forum members. I have the following problem, the car on a cold engine normally walks for about 10 km, then it starts to cut it off as if the turbo did not work at all, I will add that the turbine I never heard the symptoms that it was raining. Best of all when it comes to normal fisie shows the increase in combustion when I press the pedal into the floor, then how it cuts off the zero reaction goes like with 70 hp and on the computer when burning also zero reaction when I press the pedal to the floor. The symptoms are such that when it starts to slurp it is sometimes like gently pressing on the gas at constant revs it will sometimes be put off by the meter and pulled out normlanie but the longer I go the less chance there is. Of course, at the beginning of the filters (air and fuel) I mentioned excluded. I suspect vacu pompe because when I press a few times when driving, i.e. 3.4 times pulsationally, the brake gets hard and no reaction, I have glued the vacuum from vacuo because I have the original Luka. The vakuometer the mechanic measured the pressure was inappropriate but I do not know exactly what the values were. The pushers were regenerated a year back, i.e. the replacement of the sprays so much that the glass on the roller is already worn and the deviations are different on the computer up to -2.6. Now I do not know what to pay attention to whether the flow or turbo that already throws oil on the intercooler, but the geometry was checked and the barbell is also right, in vacuo or maybe this shred the camshaft I will add that today I still had a problem with firing on warm when I came back because I was doing 80 km. I'm asking because I've got a little money in this car and I do not want to exchange everything and put thousands in this car how to diagnose the cause someone can tell something because the mechanic prompted the exchange in vacu and how it does not break it later turbo for regeneration also I do not really smile . Can it be the symptoms of this threadbare roller that I do not evenly work on all pumps, but now I am having problems with this but I am surprised that if it is silted, it is gentle to gas or 3 or 5 gas, and after a while it will rarely get gas into the floor and pulls later 4 and 5 just keep it on rotation, it goes normally as it will catch and let go gas and it is silting again what else I noticed it is strangely hard to sound like a muffler blown especially warm (exhaust system excluded checked and everything is ok) . I explained best how I can do all the symptoms and what I noticed in advance thanks for help because I've had enough of this car for 4 years alone. greetings :)

    Hello. The injection error is almost limit but it does not have to prove the damage itself, but the condition of the engine. The ripped shaft is known to be replaced but if it was its fault problem would constantly annoy in every speed range. The turbine does not have to throw oil at the intercom, but it may be that the geometry will be baked. I would like to bet on the problem with it, however, we still have too little data we need real-time parameter data. It's firing on a hot engine, how it looks, you have to spin 5min or 5sec? last worked there was a topic on the electrode with the fact that on the priv I told my friend to change the fuel and how he took the hand off, the error codes are sure to have some.

    today I just turned up this problem, I was shooting 3 times for 10 seconds and nothing for 4 of them started off once, but once it goes silly, it usually happens that when it is running it will cut it off and there is no chance that the norm will pull when it goes I'm firing a ride and it's normal for a while. I do not remember errors anymore, n75 (http://allegro.pl/zawor-doladowania-turbiny-egr-n75-audi-a4-1-9tdi-i5621009400.html) this sensor was replaced by a new one and nothing helped ... (the fuel was also lane from various stations).

    When it comes to silting, I bet on the geometry of the turbine, unless the error related to the supply of the valve. With the ignition, the pump in the tank, the engine speed on the starter is too small, the shaft position sensor ......

    but, again, the geometry is controlled by the vacuum from the pump, which also does not require me ...

    As you do not even know what the vacuum is there. And after firing the pear draws the barbell of the turbine to the end?

    that's what I'll check today so maybe I will not be misleading (probably around 0.9 should be at the exit and on the potato 0.63) and the bar was checked only mechanically not before vacuuming with vacu ... I check everything and write :)

    And will not it be a flow meter? I would like to add that today the car started to waver on the turnover at 1300 and then it dropped again to 900?

    Turbo cleared, barbells as it should be, geometry in order, small regeneration done / Trying blinds egra also nothing helped / Replacing the flow with good equipment and the same / I spread my hands already and goes to clairvoyant ... Maybe some suggestions?

Topic summary

The discussion revolves around performance issues with an Audi A4 B6 1.9TDI 130PS, particularly when the engine is cold. The user reports that after approximately 10 km of driving, the vehicle experiences a significant loss of power, akin to turbo failure, with no response when the accelerator is fully pressed. Initial checks ruled out air and fuel filters, leading to suspicions about the vacuum pump and turbo geometry. Various responses suggest potential causes including injection errors, turbo geometry issues, and vacuum control problems. The user has replaced the N75 valve and checked the turbo's mechanical components, but the problem persists, prompting further investigation into the flow meter and vacuum levels.
