09 Jetta Throttle Oil Leakage
More than 90% of the oil leakage problems are caused by the rubber sealing ring inside the gearbox being alternately changed by cold and warm temperatures for a long time, which leads to a large loss of plasticizers and softeners, corrosion, aging and hardening. At first, there was oil leakage, and then it began to drip slowly. After a long time, the sealing ring broke.
