P0400 - Exhaust Gas Recirculation Flow Malfunction

The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); on Facebook No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions.

Causes: A code P0400 may mean that one or more of the following has happened:

  • Plugged EGR passage which restricts the flow of exhaust gasses
  • Faulty EGR solenoid
  • Faulty EGR solenoid wiring/harness
  • Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
  • Faulty EGR valve

Possible Solutions: Since EGR valve designs are different, no one test will suffice:
  • Using a scan tool, operate the EGR valve with the engine running. If the engine stumbles, the problem was likely intermittent wiring problem or intermittent blockage problem
  • If engine doesn't stumble, operate the EGR valve manually, if possible. If engine doesn't stumble and die, the ports are likely plugged. Removal of valve and cleaning of all ports will be required
  • Checking of solenoid can only usually be done with a scan tool, because most solenoids operate with a duty cycle of voltage, rather than constant voltage
  • Check all vacuum lines, hoses, etc for any damage
  • Visually inspect the solenoid harness and the solenoid for damage
  • Replace EGR valve

Hope helps (remember comment and rated this).

The motor ligh its on whats mean?

You mean either the check engine light or the service engine soon light?

It means your computer detected a fault in one of the components it monitors and you need to have the codes pulled and the problem fixed.

Catalytic converter cause engine on ofter replace catalytic converter and clear the light drive abouse 100km engine lighe on can tell me why

Vw's are a little tricky, you have to call the dealer to tell you what the codes mean. Go to Auto Zone and have them read the codes for you. If they reveal what the codes mean thats fine. But if they don't, get them and send them to me . I'll help you out with this one.
