After months of testing, VDS performance are pleased to announce that we are now able to carry out a complete inlet valve clean/de-coke service for all TFSi engined vehicles.

Our comprehensive service involves removal of the inlet manifold followed by extensive cleaning of the individual inlet valves and ports to remove all traces of carbon build up,  restoring lost power and reducing misfires and poor economy.

Our inlet valve clean/de-coke service includes all necessary cleaning materials as well as OE replacement injector seal kits and a new inlet manifold gasket.

We strongly recommend that the fuel injectors are thoroughly tested and cleaned at the same time as they are also prone to blockages caused by carbon build up
