Audi a4 2006 lighting issue

[Ozzy997]

Hi guys

Strange faults developed on the audi it's a 06 plate saloon,

Interior light switch is always set in middle position which is light comes on when doors open.

Recently the interior lights front and rear are staying on constant even though doors bonnet and boot is closed .

Only time the light goes off is when I take the key out and lock vehicle using remote or when I turn the interior light switch to off position.

Everything else is working fine

Any help would be appreciated
