Engine warning light

[Duns]

Hi, wondering if anyone has this same issue and knows what the cause is.

The engine warning light light comes on and the ECO light on the left side turns off at the same time. I mostly drive the car in eco mode.

Then after a few hours the engine light goes off and the ECO light comes back on.

I’ve had my mechanic test it with the computer and it has come up with these codes:

Code P0015 Camshaft Position ‘B-Timing Over-Retarded (Bank1) and also P0365 Camshaft Position Sensor ‘B’ Cicuit (Bank1).

The car drives normally when this happens.

Any feedback would be great.
