Those DTC's are corrupted. Try using a different code reader and report back.

Re: Check engine light

Sounds like you need to go smoke some rubber and bounce it off the rev-limiter LOL

P2002 Diesel Particulate Filter (DPF) Efficiency Below Threshold Bank 1

A 'crisp' run down the nearest freeway should clear that up for you...

Re: Check engine light

When it happened to me it was always an Evap error code. Has to do with vapors returning to the fuel tank.
Service guys would ask if I had a diesel when I called. Or had I just filled up recently?

Your results may be different.
