Good afternoon everyone. I am sure this question has come up many times but I couldn't find anyone with a solution for this so I figured I would ask.

I have a Thermador cooktop that is about 14 years old. A few weeks ago one of the burners stopped sending spark to ignite the gas form the burner. We were told by the repair company (which have used in the past and trust) that the spark electrode was the culprit (the technician switched the part from front to back that the burner that wasn't working was now working) but that the part (part # 00415124) was discontinued years ago. I called the manufacturer (Bosch) of the part and they told me the same.

What are my options to replace or repair this electrode in this situation?
