Help!!!
 

Hi everyone.

My Merc Benz CLA 180 2014 was involve in an accident and more of the accident affect the engine underneath, but after I fixed it everything was fine until I notice it was doing hard starting like take few seconds before it start, then I diagnose it and this is what I got: (The position of stored the exhaust camshaft bank 1 is implausible relative to the position of the crankshaft there is a signal above the permissible limit value.) but when the guy that diagnose it clear the error MSG the car started normal and check engine light go off but after few minutes I restart the car again and it hard start again and check engine back on.

Also I notice when I accelerate I heard a rattling noises in my engine. I am not sure what is going on because the car is moving normal.

Can someone pls explain what this mean to me. I have change the Crank and Cam sensors.
