Disadvantages of the VW JN engine
- Most of the problems of this unit are associated with malfunctions of the KE-Jetronic system.
- The injection system cannot be called unreliable, just few people know how to set it up.
- Hydraulic compensators here do not like low-quality oil and can simply start to freeze.
- At high mileage, lubricant consumption occurs due to the occurrence of oil scraper rings.
- Weak points also include ignition system components and temperature sensor.
