Ford P0400 and P0401 are fault code that relate to the EGR valve. Rather than replace this troublesome EGR valve the customer requested the EGR to be removed (blanked) and disabled by the software so as this fault cannot occur again.
The EGR Valve on the 1.8 TDCI mondeo is located on the top left hand side on the inlet. the EGR pipes are blanked at the exhaust side to prevent the flow of exhaust gas entering the EGR valve itself. We use steel blanking plates to ensure no gas enters the EGR valve, The blanking plates are accompanied with a remap to disable the functions of the EGR valve and prevent any fault codes and limp mode coming back.
If you are suffering from EGR faults or are looking to disable your EGR valve please feel free to get in touch. We are based just off of the A12 in Suffolk between Ipswich and Lowestoft in Saxmundham.
