2003 - 607 Diesel electrical issues

Hello,



I've got a few problems with a 607.



When starting there are no lights on the dashboard, and although the car starts it seems slightly sluggish to start. The odd thing is the interior fan also keeps running at full after the engine is stopped and the only way to get it to shut off is to disconnect the battery.



I've got one of those cheap Bluetooth OBD error code readers and it returns the following:



Confirmed Trouble Codes

-P0026: Intake Valve Control Solenoid Circuit Range/Performance (Bank 1) (Powertrain, Generic)

-P00C2: ISO/SAE Reserved (Powertrain, Generic)



I've been searching through various sites but there seem to be multiple causes for those codes and none match the dash light and fan issues I'm seeing.



Does anyone have any ideas?
Please help.

Thanks!



I didn't find the right solution from the Internet.
