This kit will address issues that can cause limp mode, low power, low mileage and smoking in any 1999.5-2003 Jetta TDI, Golf TDI or 1998-2003 New Beetle TDI. This kit includes:

  • VNT-15 Turbocharger Vane Actuator (normally $99.95)
  • Mass Airflow Sensor: Choice between Pierburg insert, Huco MAF with Housing, or Bosch MAF with Housing. 
  • N75 Pressure Converter Valve by Pierberg (normally $69.95)
  • Replacement Vacuum Hose for Engine Engine Bay, 3 meters of small diameter and 1 meter of large diameter hose.

We've been receiving an increasing number of calls with problems related to the pieces in this kit - a seized actuator has been causing limp mode, a failed N75 valve has been causing a low boost condition, a weak MAF is causing low power and smoking, etc.

Most often the problem is solved with a combination of parts - for instance a malfunctioning N75 or leaking vacuum hose has not been able to keep the vacuum pressure required to move the actuator on the turbocharger, so the actuator arm has become stuck and also needs replacing. And if the turbocharger control system has been fixed but low power, bad economy may remain due to a weak MAF.

This kit covers all these possibilities, and at one time or another every car will require these pieces.

If you've been waiting replacing one or more of these items, order this kit.

1998, 1999 New Beetles and 1999.5 Jetta and Golfs will require the newer style N75 connector to use the new style N75. You can add one to you order below.
