Exclamation Mercedes C350E 2017 , Issue!

Hi Guys,

I had a question and hopefully some one has experienced a similar problem,

I have a 2017 C350E Hybrid, It's done 50,000kms, A week or so ago i started experiencing a issue with the transition from Electric to Petrol, the car kicks in very aggressively like there is a delay, before it was smooth change the stop start ect, and at the same time i noticed my ac isn't cooling anymore? i'm not sure if this is something related to each other? any way being a w205 and i have had them in the past i changed the main battery in the trunk and also the 12V AUX battery in the car, but this hasn't done anything the aggressive change is still there but if i drive in petrol only it's fine, so no issues with trans and if i drive EV only it's fine,

I pulled out some Error codes and the one that kept coming back after erasing the codes is P052E71, But surely that can't be the cause can it?

I have attached the pictures for the fault codes,


Again many thanks
