How do you disable egr valve on a 1996 VW Passat TDI?

Answer 1

You should have VAG COM diagnosis equipment,or some another,which could allow you to make communication with ECU.Once you enter to Engine Control Unit ,you should log in by entering 12233,and then you should go to adaptation,and in group 3,EGR group, increase value from 32768 to 33768 and save it as value,it will turn your egr valve off,and give your ECU information to increase amount of O2 as well as fuel in it's a/f mixture,which will increase power of your engine.Afterward it's good to make test driving in order to check behaviour of MAP sensor,so if doesn't go above 2400mBar measured pressure,you can leave it in that position,it will not turn your Turbocharger off.
