ds3 problem , what are these fault codes?

[peter789456]

hi, my wife has a ds3 1.6 diesel. the car drives fine but won't rev over a certain amount (so mainly this is an issue for overtaking) on the computer screen it keeps flashing up with something to do with fault , take it to a garage . she has to just click the screen every time to dismiss it. we had a local garage plug it in and ran diagnostics on it. The mechanic was unsure. The service light on the dash is also illiminated. Could the computer be at fault or is one of these codes causing it. The picture attached is the faults. There is also sometimes an issue where we fill the car with ad blue and sometimes it still thinks it requires some more ad blue, but not sure if this is related? any help is much appreciated.

Majority of the fault codes throw up on my DS3 Diesel are usually caused by DPF being full
Has that been checked
A fault will be causing the light- whatever the fault is. Sometimes a secondary light comes up on the dash to explain the fault further. But sometimes it doesnt
Have you googled these fault codes?

hi, thanks for replying. nope haven't had the dpf checked - do you think that could be the first thing to try? did your dpf cause the car to restrict revs? not googled the fault codes , cheers
