Part Number: 7021081. How does this repair service work?. 20-02 Two Speed Error On. We test it and then repair it. Warranty is for 1 year. The warranty starts from the date of departure of our repair center.

This is a repair service for defective controller modules, not a replacement part purchase. You must ship your module to the repair facility for diagnosis and restoration.
The service covers multiple controller models including E35, E32, E42, E45, E50, and E55 (Part Number 7021081). Common issues repaired include dead/no power, display failures, non-working gauges, broken connector pins, water and corrosion damage, button failures, hydraulic issues, two speed errors, low battery voltage readings, and lighting problems.
The repair process is straightforward: purchase the service, receive packaging instructions, ship your controller base, and the facility will test and repair it within 3-5 business days after receipt. Your repaired module ships back with a one-year warranty covering defects from the original repair (excluding lightning damage, physical damage, and unrelated failures).
Important fees apply: if your module arrives in working condition, a 30% non-refundable testing fee plus return shipping applies. If the module cannot be repaired, a 50% repair attempt fee is charged. Additional modules for testing incur a $20 flat bench fee each plus return shipping.
Contact the seller before ordering if your symptoms are not listed or if your board has been previously serviced or has missing parts, as these are not accepted for repair.
