Hi could you explain why did you divert the whole circuit to the turbo? All is very simple. In a collector the gage pressure\vacuum is established. When you release a pedal, egr Is opened on 100 % and is closed air valve as on 100 %. Pressure falls to certain parameter. If simply to establish a plate that parameter it will be too small - result check vsc. If submit air from turbo we can't to receive vacuum in a collector! I have egr closed for over 5 days and there are not any errors on VSC. For sure if you remove that circuite and just close the valve you will also see that VSC won't trow error. But it is a matter of personal choise I think. Thank you for the clarification and have a great time driving :) Rgds

Hi Guys I need a repair manual for IS 220D. Can anybody help me? Thank you Rgds

Not sure for that. I have had BMW 330D with closed EGR valve. I have driven it over 150 000km and I did not have any problem with the turbo. Probably on theory you are right. But having in mind that gasses in turbo are traveling so fast I cannot imagine how can EGR probably cool them. Whatever, I like the way my car has waken up and I do not want just to clean the valve but I think I will leave it that way. Another thing I will do will be to remove the stupid filter for the gasses and the stupid 5th injector and if succeed in doing that I will be very happy :) Rgds

Hello Tani, I'm interested in blocking the valve but when i cleaned it for the first time a couple of months ago i saw that there is a solenoid opening and closing the valve I guess when it's necessary. If i understand well there has to be some sensor telling the ECU to open or close the valve but if you block it this sensor will somehow notice it. Please monitor it for a few days and let me/us know if there are any issues. I hope there aren't any problems because it would be great to get a bit of more power with such a simple modification. Rgds Georgios Don't worry close it. This valve is controlled by ECU but ECU cannot measure if gasses are passing. So closing it does not mean you are blocking the movments of the valve controlled by ECU you are just stoping the gasses and they are thrown through the generation. I will update after several days. Today I did 50-70km urban cruise and no problems occur. Rgds

Greetings from Bulgaria Today I closed the EGR and the car waked up. Nothing happens no errors neither switch to recovery mode. EGR is not connected with computed on this engine and can be closed without problems as for the fuel consumption it remains the same. 11-13lt/100km urban drive 7-8lt/100km highway drive. Regards

PROBLEM FIXED!!! It was very dirty EGR. The guy who was repairing the car told me he had the similar problems with EGR valve and he closed it. Just put a small thin metal between EGR tube and the valve itself and the car waked up. All you sould do is to unskrew two studs on EGR tube and slide a small metal between tube and valve. The difference it obvious and significant. Nothing happend with the computer no warning light neither any errors. For all of you who want to try just know that the EGR valve in this engine could be bypassed without any errors.

VIF not sure but REDEX yes. I will try that.

Greetings from Bulgaria. I have the same issue. The car is clumsy and sluggish. When I try to accelerate it stumbles untill it hits 2500rmp and the turbo is on. The engine often turns off when it is cold and I should turn it on again and again. When the car is cold I should pump on the acceleration pedal several times before release the clutch and the car moves or it will turn off. No warning lights on the dashboard. Will try to clean the EGR tommorow. Please give me any advice.
