Vehicle is still new and should be under warranty, if so, I would let the dealer sweat over it. Our database does not have any information on the codes you posted.

This is the code I found for Audi vehicles.

P1025 AUDI - Fuel Pressure Control Valve Mechanical Malfunction

Possible causes- Fuel pressure control valve circuit is short to ground
- Fuel pressure control valve poor electrical connection
- Faulty fuel pressure control valve

This one is different for Mitsubishi.

P1025 MITSUBISHI - Exhaust Engine Oil Control Valve Circuit

Possible causes- Exhaust engine oil control valve circuit is open or shorted
- Exhaust engine oil control valve circuit poor electrical connection
- Faulty exhaust engine oil control valve circuit

I am not sure which is the correct component fault in your case.
