As you drive, your vehicle’s oil and fuel produce vapors that are very harmful to the environment. The EVAP system works by drawing in fresh air, gathering the unburned vapors, and delivering them to the intake system, where they can be re-burned in the engine. If there’s a problem with the EVAP system, such as a leak or blockage, a trouble code will be generated, and the check engine light will come on. The EVAP system is a complicated network of hoses, valves, filters, and other components. Although it’s not dangerous to drive with an EVAP leak, it’s best to get the issue repaired as soon as possible. Issues with the EVAP system are one of the top 5 reasons for the check engine light to come on. EuroCar Service specializes in all European vehicles, call us today at 206-527-8828
