Disadvantages of the GWE20CB engine

  • In the first year of the engine’s release, owners of Wey crossovers complained about the oil burner.
  • However, already in 2021 this problem was solved and now such cases are rare.
  • Like all direct injection engines, it suffers from carbon deposits on the intake valves.
  • It is also worth noting that the original air filter poorly protects against sand.
