Here is what I got from an independent mech the other day.

P0116-coolant temp circuit
P0455-large EVAP leak
P0513-incorrect immobilizer key
U0426-invalid data received from immobilizer control module

I had a few other codes but once I cleaned my MAF sensor it removed my check engine light. So now my question is, is can anyone help me out with these? Anything I can do myself or am I in the hands of LR or and indy mech?

 

I have the same issue with mine. P0513 incorrect immobilizer key.

It came up with U0426.
My fob was not opening the doors unless I was at least one foot away. I had replace the fob batter once already this year. The dealer said just put in a new battery. I did but it no resolution. It made it worse.
I believe that there is a code lost communication with instrument control panel, is actually messing around with various components in mine and throwing problems around. Not sure of the fix. Have been trying for 5 months now. If you find out post your results.
