What are you using to read the DTC's ?

That's quite a range of fault codes has any work been done on the vehicle recently ? Has the air filter been changed and the air box lid is not properly seated ?

using a delphi ds1500 and also a elm with forscan same codes with both its had a full service but it had done 400 miles to Cornwall before anything happened  another site suggests egr but confused as theres no codes for the egr strange thing is it will idle for ever with no problems it only happens when driving
