ML350 bluetec 2010. W164
low acceleration

in my ML350 Bluetec 2010 last week I change 6 fuel injectors , air inlet manifold valve , maf & new air filters

the car acceleration is bad especially when climbing hills or mountain and delay in response when press acceleration paddle
the scan tool reads nothing ( only code P246B permanent , I think this because I delete DPF & ad-blue )
I check electric fuel pump it reads 8 bar ,
I went to several workshops they are confused on says pressure control valve other says high pressure pump last one tell me to change the engine 😟 they make me down
yesterday I'm driving on little slop hill the engine turned off after the car stops start the engine and go

Any kind help please

thanks

There are no "P" codes whatsoever in any Blue module. You need a scanner that will read codes in all modules.
