Question Car goes into limp mode - error codes

Today when I started my car the yellow engine light came up and the car goes into what I think is limp mode. No turbo is present (I think) and the transmission wont kickdown at all.

I've red out the following error codes: P2668 who I managed to erase and P3002 who wont go away. Anyone here who knows what the codes means? The car is a S320 CDI.

From my research it seems like something is going wonky with the accelerator pedal position sensor. This will cause limp mode. You will need star diag to further diagnose.

It was a sensor in connection with the particle filter who was the problem according to Star. Havn't got the part yet, so I have to wait and see if the problem goes away.

3002 is for the DPF differential pressure sensor (when you read codes with Star).

It could be the actual sensor or just the tubes, check those. A relatively common issue with V6 CDIs/DPF cars.
