1997 993 Varioram

Engine

Vehicle Information: Year: 1997; Body Type: Coupe; Total Mileage: 69,xxx;

Greetings,During recent spirited drives, I've noticed an absence of the "intake note" change when the varioram sliders change the airflow in the induction system. After repeated attempts, I'm near certain that the varioram is failing to function properly. I understand that this system is controlled by a solenoid that activates at a specific RPM. Reviewing the relays/fuses associated with the electrical system, there are no relays/fuses listed in either the front or rear fuse/relay panals. Any other suggestions for trouble shooting, or should I proceed to the nearest holder of a Bosch Hammer?Thanks for you continued support and guidance!
