Evening all my car has auto boot opener/closure. It hasn’t worked for about 2years so today I decided to investigate. I checked wiring coming into boot on n/s hinge and around 11 wires where worn and shorting together and on wire split. I soldered and insulated wires. And all good switches on bootlid lit up and it now works... however only opens halfway. I checked in the manual and it says opening height can be set to halfway or ful on saloons and estates via menu on dash. I followed instructions and checked but can find the option in the menu... any ideas guys???
