Hi a few times now when under load, or on the motorway for a longer period my car drops a gear shows the engine management light and wont change up gears unless i switch off and on.
Everytime this happens i get the same code.
P246309 the soot content of the dpf is not ok there is a component fault.
P0299FA The boost pressure of turbocharger 1 is too low.
I have changed the turbo pressure transducer, still the same issue.
Any help where my next move goes to eliminate this issue.
