Has anyone any ideas

[Davsky]

Hi all
First post so please go east on me.
Got a E88 120d msport convertible with a few issues.
1 cold start - sometimes it does sometimes it doesn’t. Had new injectors, glow plugs glow plug control unit and fuel tank pump, all thrown up codes and been replaced but non start from cold is still not consistent
2 EPS fault light comes on after start up and stays on, power assistance -sometimes it does sometimes it doesn’t?
Any help will be greatly appreciated
Dave
