Hi, I have been given a list of fault codes from my vehicle,  listed below are said codes.

The dealership says to be having all these codes at one time would indicate the dpf filter and egr system has been altered/ tampered with, obviously being a diesel.

 

Would this be true? Thanks.  
 

 

Last Trouble Code(s)
P008A: Low Pressure Fuel System Pressure - Too Low
P0401: Exhaust Gas Recirculation Flow Insufficient Detected
P242C: Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 3
P244A: Diesel Particulate Filter Differential Pressure - Too Low (Bank 1)
P1335: Ford: Throttle Position Sensor in Exhaust Gas Recirculation (EGR) - Operating/Range Problem
P0490: Exhaust Gas Recirculation Control - Circuit High
P042F: Exhaust Gas Recirculation A Control - Stuck Closed
P042E: Exhaust Gas Recirculation A Control - Stuck Open

    Problems start upstream - so looks more like EGR trouble, which is then affecting things later in the system. The DPF is the a$$hole of the car, pretty much anything upstream goes wrong and it also throws errors! For example, if you have too much EGR it will clog the DPF. The DPF suffers for other problems.

    I’ve had confirmation that the DPF has been removed :).
