HIGH fuel pressure

[E220silver]

High all
ive recently bought myself a 2007 w211 e220 2.2cdi .
last couple of weeks the engine management light has come on , ive taken for diagnostics but not star system diagnostics , they've both came back and said fuel pressure , well first one said fuel pressure ans second one said high fuel pressure . the symptoms im havin while driving is slow acceleration after about 15 mins of driving . anyone out there got an idea what the most likely cause of the problem is ?

possibly fuel rail high pressure regulator (seals)

yesterday and today the engine management light never came on at all ?

Had a star diagnosis and it came back with injector number 2 is faulty . Replaced it with a new one yesterday and the engine light is still on

Did you reset codes? Did you check wires (contacts withdraws easily inside connector, or wire is worn)

I didn’t do the job myself I had it done at a garage , he cleared the codes and the light came back on after 10 mins driving .
I phoned him when I got home and he couldn’t believe it .
Gotta bring it back to him later today so he can scan it again and see what it comes up with .
