Hi guys i have a startup issue with my 2015 s63l (long wheel base) has the m157 biturbo engine. Sometimes when i go to start my car it diesnt start up sometimes and then it will start fine most times, ive had it checked and few error codes, (see attached files) ive been told its a relay switch.
But i have no clue what part i need to get and what needs changing, anyone have any ideas please
So far it seems like i have fixed it, and the error codes have not re-appeared. For future refrence is anybody does run into a similar issue like mine or has similar error codes here is the fix i did:
In the engine by on drivers side, I opened the fuse box and replaced 2 relay switches; H slot (Starter Circuit Relay 50) and G slot (Circuit 15 Relay In Engine Compartment) see picture for the old relays below:
(old relays in fuse box) Here is the Photos of the new relay switches now:

The part numbers are diffrent i guess updated parts i got them from the dealership and i gave them the part numbers of the old relay switches and told me these are the new updated ones with new part numbers.
