2004年11月27日 · in VCDS for EDC15 ALH cars the n75 value shows the percent the VALVE is CLOSED. so if you see 100% that means 0% vacuum is being passed -valve is fully closed, not passing any vacuum through, so vanes wide open, least boost. 0% means valve is fully open, full vacuum, for max boost. for MAS15 (wastegate cars - AHU) and EDC16 cars (BEW PD cars in ...

2012年3月16日 · Replaced a very frayed vac line between the n75 and turbo gate activator. Have good vac level up to the valve, and if i bypass it, connecting the vac line straight to the turbo activator, i get boost just fine. How do I check the n75 valve to make sure it's the problem component instead of some other component causing bad signal.

2010年5月1日 · The only vacuum lines left on the car are the line to the booster, and the three lines for the N75 valve. I have a boostvalve, but have removed it from the car to reduce variables Tested vacuum from pump at idle (~25 in.Hg) The car should run at about 19 psi (RC2)

2002年7月15日 · The Haynes paper manual says that the resistance should be 25-45 ohms. I checked my N75 and another one on my other tdi that is having no problems. Both times I get 16-17 ohms. I suspect the manual is wrong. I'll check the …

2005年4月22日 · All fingers pointed to the N75 valve. I am getting repeated CEL, with N75 failure code. I tested for voltage at the N75 connector as per VW service manual - all OK. The original N75 valve tested OK per VW service manual as well. Even though the original valve tested OK, I installed a new one to eliminate any doubt. All this to no avail.

2010年3月31日 · The N75 plug (not plugged in) should have 12 volts on 1 pin and the the other may have low voltage if any. The 'other' would come from the ECU and be pulsed as needed. The 16.4 ohms is in the range. The N75 resistance should not change with temperature. Yours is in the range. You did not mention what problem you are having.

2010年10月6日 · The N75 valve is like a switch controlling the turbo wastegate actuator. The wastegate itself is normally closed allowing exhaust gases to spin the turbo. When the wastegate actuator opens the wastegate, exhaust gases are diverted away from the turbo. This is necessary as excessive boost would...

2024年9月26日 · Then you have access the N75. The job of the N75 is to control the variable vanes of the turbo by vacuum so that the boost stays at the correct level as decided by the ECU. The boost sensor (AKA MAP sensor or N18 sensor) you changed reports to the ECU about how much boost exists. This is so the ECU can order your N75 to move the vanes accordingly.

2003年12月1日 · N75 should be the same. I plugged both outs, and applied vacuum on the in. Then took my fingers off the outs. Did this a few times, and the sound changed... Like it was stuck before and now not anymore. And its been working great and no codes. Again, this was the egr and not n75, but same concept. I think I have a spare n75 if you think you ...

2013年11月8日 · The N75 valve is like a switch controlling the turbo wastegate actuator. The wastegate itself is normally closed allowing exhaust gases to spin the turbo.
