Auxiliary air valve, Repair Service

This is for repair of your auxiliary air valve with new internal parts, NOT a part that is being sold.

Before purchasing this repair service, please verify that your auxiliary air valve has a resistance in the 10s of Ohms between the two contact pins in the back. If you see infinite resistance, please clean the contacts and try again.

After confirming resistance in the 10s of Ohms you can purchase the repair and send me your broken Auxiliary Air Valve. It will be opened up, fitted with new internal parts, tested and resealed.

Parts from Germany, labor and shipping back to you is included in the price.

To see how the repair is being performed, please check my YouTube video below.
