WARNING: This page is about a different car, the 2015 Volkswagen Beetle. 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 part if there are leaks in spite of correct tightening specifications.

-- Perform a road test and press the accelerator pedal all the way down at least one time.

-- Check the high voltage system again for leaks.
