Hi everyone wanted some help if anyone on here can! So I have a 2015 Mercedes c63s edition 1 car was running fine or I thought it was until I took it to dyno to just see what the car outputs anyhow car came back running around 470 which was quite low then started to get the flashing engine light took it to a specialist engine place after taking it to Mercedes several times having new coil packs new spark plugs oil change and everything still not finding the issue in the end amg specialists diagnosed the piston rings to be clogged on two pistons car had a whole rebuild new turbos new radiators and now engine is all sweet anyhow after doing the run in miles the car is in soft limp mode and not running nowhere near how it should plugged a scanner in and faults that I’m having are related to my exhaust valves anyhow I’ve changed both the rear exhaust valve actuators and still got the same issue the middle valve has been cut out and got a exhaust valves simulator in their so I’m assuming theirs a fuse maybe that is blown but unsure can anyone help on this
