Hello, can someone please help me have bought a Mini r56 174 ps with engine damage, have bought a used engine with new control chain set, all built in etc. But the engine does not start because it has no ignition spark have checked everything: NWS, KWS, all plugs what could this be still. The control unit? Or can the control time be adjusted? I don’t know any more would be very happy about advice, have also this error in it.
