Amarok horn siren after starting and is intermitted

[PieterM]

Hi, my Amarok D/C auto recently started with intermitted problem. After starting the engine before driving off the horn start to siren but the hazards do not come on. VW Vredenburg advised that I have to reolace computors to value of R4000 after troubleshooting, now the fuel gauge don't work after troubleshooting. They reckon that the imobilizer do not talk to the horn/alarm but everything else regarding imobilzer work just fine. Doors lock and unlock normal. Any advise will be appreciated
