Around with the vestra 2.0 dth !!!

Good to all, to see with a 2.0dti 16v vectra, when you accelerate it, everything goes "firewood" and it is turned on in the picture and everything is lazy (the turbo stops entering), I have reviewed all the depression sleeves to the electrovalvulas (including the AA and heating), the electrovalvulas give I think I think I think 32 ohms, they seem to be well. Turbo ok, if I disconnect the tube from the admission pulmonic electrovalve For looking at the vacuum depressant ... and these electrovalves it carries, I think they hide some mystery, because when some, or bridges the air exit, do they fail ..? Let's see if anyone has encountered this breakdown and its solution, because it is said that it is famous in this model, but nobody knows how to determine what Concha happens ... greetings !!

Hi Ismael53, tube a similar exprence in an Opel/Chevrolet Combo Motor Y17DT and Y13DT. According to my info, these systems should be very similar to the case you have. The switchboard that controls the engine (ECU) has direct interference in the pressure nephew pressure. On the one hand it receives info of the pressure in the multiple, on the other hand calculates according to several parameters an ideal pressure slogan and compares with the one that currently exists. To be able to regulate it, it has an electrovalvula that crosses the depression of the engine depressant, it is consumed to place the turbo wastegate (pressure limiting valve) in the desired position to control supercharging pressure. The ECU Motor sends digital pulses (PWM) to the electrovalvula and thus "regulate" the void that produces the depressor (position the Wategate with pressure). In my case in the problems that I saw, they were not exactly the same, in one the ECU could not control the pressure and was escaped from the consuigna ranges, and not being able to control the preion enters the pre -technction mode and leaves you with a reduced flow of injection, while generating the code. (Trisada Electrovalvula Produced Loss of Depression).
In the other case it was that when taking out the starting engine to repair it, when installing it they squeezed the emptiness conduction that VAT from the control electrovalve to the turbo. In any case, I recommend Scanare, because there is not only one type of error in these systems with respect to the supercharging pressure control. Eg another similar case with a friend that the control unit towards everything positive to raise the pressure of supercharging. However, I didn't succeed. In this case, the code referred to the spare -food was always lower than the calculated slogan value (in this case Wastegate Valve stuck open). In the previous cases the pressure was about the slogan, and also the module tried to control it, Pèro could not. d ehecho with the connected scanner and an vacuometro connected to the pressure electrovalcvula for pressure ECU that varies the impulse width (controls current), closed or totally open. In the first case if the Fuciona OK system should obtain atmospheric pressure, in the second the depression that the vacuum pump can generate. Finally when the depressant fails, problems are generated in all empty controlled systems (codes), however when the problem is in a single system, specific codes are generated to each system. This is why Diagnsys the Scanner is so important. I hope it serves you, we are in touch greetings.

Thank you for the answer, it agrees more or less with what I imagined, it is in the case that you comment in which, it reduces injection flow when I turn on failure, the thing is that the Turbo Regulation Electrovalve And even the brake servo, lest he is punctured, to look at everything to see. greetings

Hi Ismael, the valve is progressive according to the digital impulse width sent by the ECU, it is the major way to precisely control the current that passes through the valve, therefore the mangotic field that is generated in it. Sludos cordials.

Hi Ismael53, did you solve the problem, if so, I intended to know what it was, if you fancy, eat the diagnostic experience? Slaudos to all.
