P1527 BMW -

Question

I accidentally unplug the ECU connections while the car was running. Now the car has this code plus its idling really rough. What to do…thinking maybe a ECU reflash would do the trick? Please help. Thanks

P1527 Camshaft Position actuator "A" control circuit signal low Bank 1

Circuit low, this is more of a power supply problem to the variable valve timing actuator (VANOS) of the inlet camshaft.Check the charging system , A DME reflash will not do the trick.
