1.8T Engine Notes Technical Support
Given the age of most vehicles with the 1.8T engine it is important for the vehicle to be 100% healthy before having any performance software installed. If your vehicle has any running issues in standard form our dealers will be able advice on how to proceed with rectifying issues. Any running issue needs to be resolved before the vehicle can be upgraded.
We get asked a lot whether you can run an atmospheric ‘dump’ valve on this engine. Whilst some people think they sound great the engine is not designed to run with an atmospheric valve, it needs to use a recirculating diverter valve to correctly function.
