Question about 2005 Volkswagen Golf
Fault reads: EGR System Insufficient flow: P0401.
Cleared fault light using a VAG5053 but light comes back on within a few days.
Would like to know where the EGR Valve is (Picture would be great) and how to test, clean or repair it.
Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)
Hope this helps, D.
