Hi everyone, thought id ask before i book this one in to be looked at: Main boot lock inoperable, doesnt unlock from key fob nor driver door switch. Checked Comfort Settings - all looks ok, (auto unlock). Window section locks and unlocks as it should but tailgate stubbornly stays locked. (Its not frozen either). I dont have the elec auto close/open option. Any ideas or is it a dealer job?! Cheers .
