2004 VW Sharan Mk1: ABS, ESP & MANUAL Indicators On - 00003-Control Module/Defective Diagnosis

Hello. The patient is Sharan from 2004. While driving, when parked, the ABS, ESP and MANUAL indicators light up without difference. After connecting to vcds an error appeared
00003-Control Module / Defective.
After turning the ignition off and on, everything returns to normal and after some time the same happens again. While the error is constant, I checked the power supply and the mass of the module are all ok. The plug at the controller is not tarnished. Due to the fact that the module is not cheap, I would like to make sure and advise what else to check?

Probably the driver is damaged.

There are no non-original devices in the car?

This is often a problem

Hello again, the fault has not been removed, it seems to have intensified. When there is an error related to ABS when braking, the fuel gauge goes down and the reserve lights up, it looks as if it depends on the ABS error, when there is no error in the ABS system, the floats work normally. What does a pressure modulator have to do with a float?
