Auxiliary heater Q7

How can I access the auxiliary heater on a Q7

Passenger side wheel off and remove the inner wheel arch liner. You can do tests on it in vcds if it’s misbehaving. Common problem is them locking on older cars and the fan randomly operating on them overnight and flattens the battery overnight. You can remove the fuse for it in the car if it’s causing a problem.

Any ideas where this fuse for the aux heater is located? For the Q7 4M etron in particular.
