I have read the codes for a neighbour with a 2003 2.0 DTI. I have repaird a split in the vacuum pipe that goes to the turbo. The car was runing with no power. The car is running ok now however an intermitant car spanner light keeps popping up.
They have had a garage clean the EGR for them. I think it could still be sticking..
P0400 Exhaust Gas Recirculation Flow Malfunction .
P0650 Malfunction Indicator Lamp (MIL) Control CircuitMalfunction.
They are a nice elderly couple who I would like to help out.
They have had the car back and forth to the garage with no joy and big cost.
I hate it when garages take a lend of folk......
