The novelty received a modernized power structure of the body, a modified line of engines, a redrawn interior and a retouched exterior. At first glance, it is not so easy to distinguish it from the pre-reform version.

      Check connectors & hoses. look for leakings.
      Of no – then it could be a pump, intake or an electrical problem. Good luck.
