Smoke Testing

WARNING: This page is about a different variant/trim than selected.

Smoke testing should be used to identify a leak only when instructed by Retailer Technical Support. Refer to the manufacturer's instructions for information regarding using the smoke test equipment. Smoke may be introduced into the fuel system through the purge hose, the fuel filler neck or the DMTL  filter housing. When introducing smoke through the DMTL  filter housing, use the Jaguar Land Rover Approved Diagnostic Equipment to perform routine - Evaporative System Diagnostic Check - to make sure that the DMTL  changeover valve is energised and the DMTL  pump is running.
