What is the fault performance of Passat waste gas valve?

Passat (view transaction price | vehicle model details) Failure performance of waste gas valve: 1, EGR long-term closed state, which has an impact on vehicle emissions, that is to say, emissions may not meet the standards. 2. When 2.EGR is turned on for a long time, the vehicle will emit black smoke, the acceleration will be weak, and the fuel consumption will increase. At this time, the EGR valve must be replaced or cleaned.

Waste gas valve, also known as oil-gas separator and pressure control valve, is installed between the compressor outlet and the condenser inlet to improve the heat transfer effect in the condenser and evaporator by separating oil and gas. Its function is to recycle automobile exhaust gas to the cylinder for combustion, and this small amount of exhaust gas reduces the temperature of the cylinder and the NOX content in the exhaust gas during combustion.

When the automobile exhaust valve fails, the engine will light up the fault light, and the owner had better go to the 4S shop to check the reason.

Generally, the automobile waste gas valve with long service time is easy to fail, while the automobile waste gas valve with short service time generally does not fail. The waste gas valve needs to be replaced after it fails.
