N62 4.8is- Engine REBUILD after Valvetronic/Vanos issues/codes

[nick325xit 5spd]

There's a whole bunch of power codes in there that suggest that the battery died or got very low. When I have a sea of codes, I generally clear them and see what comes back after a drive. There's a good chance you'll have a lot less of them to deal with. BMWs throw all kind of errors when the voltage gets too low.

Edit: Also, charge the battery and confirm that the alternator is outputting ~13.5v or higher.

I genuinely would not do any other diagnostic work until you've done that.

Thanks Nick,

I cleared the codes but the Vanos codes come back (as do some others).

ECM (Engine Control Module - DME/DDE)
DTC Qty (4)

27BE DME: Camshaft Control, Exhaust, Bank 2 - Output Stage
2732 DME: Function, Camshaft Control, Inlet, Bank 2
2821 DME: Variable Intake System - Temperature Warning Threshold
2820 DME: Variable Intake System - Plausibility

I'll pop the battery on charge, clear codes again then see what remains.

How did the start sound to you?
