Why does the Volkswagen mechatronic unit fail?
1 Answers
Because the transmission mechatronic unit has high requirements for shifting and maintenance, if the lubrication level of the transmission fluid fails to meet the standard, the transmission will suffer from prolonged insufficient lubrication. This accelerates wear and tear on the transmission, leading to mechatronic unit failure and shortening the transmission's service life. Symptoms of a faulty transmission mechatronic unit include: 1. Illumination of the gear position indicator on the car dashboard. 2. Vehicle shaking, inability to upshift, loss of odd-numbered gears or even-numbered gears, and in severe cases, the vehicle may become inoperable. 3. Appearance of fault codes indicating failure to engage gears, or accidental opening/closing of the clutch.
