• Sen pitäisi liikkua sen verran vapaasti, että kokeilet vaikka imaista siitä letkun reiästä.

• To test the EGR (Exhaust Gas Recirculation) valve solenoid in a 2007 VW Touran 2.0 TDI 16v, you can follow these steps:
  
  1. Locate the EGR Valve Solenoid: The EGR valve solenoid is typically mounted near the EGR valve itself, which is usually attached to the intake manifold or near the exhaust system. Consult the vehicles service manual or look for the EGR valve and its associated components under the hood.
  
  2. Inspect the Wiring and Connections: Ensure that the wiring harness connected to the EGR valve solenoid is in good condition, with no visible damage or loose connections. Make sure the connector is securely attached to the solenoid.
  
  3. Perform Electrical Tests: You can use a multimeter to test the EGR valve solenoid for proper function. Heres how:
  
  a. Disconnect the electrical connector from the EGR valve solenoid.
  
  b. Set your multimeter to the resistance (ohms) setting.
  
  c. Place the multimeters probes on the terminals of the solenoid connector. There are typically two terminals on the solenoid.
  
  d. Measure the resistance across the solenoid. Refer to the vehicles service manual for the expected resistance value. Its usually in the range of a few ohms.
  
  e. If the resistance is significantly higher or lower than the specified value, the solenoid may be faulty and require replacement.
  
  4. Apply Battery Voltage: You can also test the EGR valve solenoid by applying battery voltage directly to it. Heres how:
  
  a. Disconnect the electrical connector from the solenoid.
  
  b. Using jumper wires, connect the positive terminal of the vehicles battery to one terminal of the solenoid, and the negative terminal to the other terminal.
  
  c. Apply battery voltage for a brief moment. You should hear a distinct clicking sound as the solenoid activates.
  
  d. If you dont hear the clicking sound, or if the solenoid feels stuck or doesnt move, it may be defective and require replacement.
  
  5. Check for Vacuum Leakage: If the solenoid passes the electrical tests but the EGR system still isnt functioning properly, you may need to check for vacuum leaks in the vacuum lines connected to the solenoid and EGR valve.
  
  Remember to consult the vehicles service manual for specific testing procedures and values, as they may vary depending on the vehicles make and model. If youre unsure about performing these tests yourself, its always best to consult a qualified mechanic or technician.
