WARNING: This page is about a different car, the 2015 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

-- Let the engine run at idle for a few minutes. Do not use accelerator and then stop the engine. The fuel system bleeds itself.

-- Replace the affected component if there are leaks in spite of correct tightening specifications.

-- Perform a road test and fully depress the accelerator pedal at least one time.

-- Check the high pressure system again for leaks.
