Because this fault code is often caused by defective wiring, we advise to thoroughly check this first. Verify that the wiring is correct, to eliminate problems. Especially the loom between the shift motor and the mechatronic is very sensitive. If the wiring is verified to operate correctly then it is probably the shift motor of the Easytronic that is defective. This fault can be fixed by remanufacturing the transmission. Create a remanufacture order, follow the steps on the website and send the part to us.

Note: When an Easytonic is send for remanufacture, the TCU, the clutch actuator, shift motor and the TCU wring loom. We need all these part to be able to test the complete system. The clutch pump is very delicate. It is better not to send this pump to prevent it being damaged during transportation. Disconnect the clutch pump, before the TCU is send to us.
