Skoda Fabia MK2 1.2 HTP BCM failure

Hi ,

Recently my Skoda Fabia 1.2 HTP  got water logged in heavy rain. After general service and cleaning all electrical connectors and relay now car starts and run as usual. power steering, instrument cluster,radiator fan, AC, and head lamps, tail lamps are functional.

However interior lights, flasher(indicators), brake lights, horn, wiper, trunk door switch are not working. After complete inspection I found BCM got partially immersed in water and PCB corroded and beyond repair. Can anyone suggest me suitable or upgradable BCM model number. Currently fitted with PQ25 6RU937084A

Thanks
