WARNING: This page is about a different car, the 2018 Volkswagen Jetta, 2017 Volkswagen Jetta, and 2016 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Replace the bolts that were tightened with an additional turn.
Replace the O-ring for the plug if it is damaged.

NOTE:

There is a risk of destroying the toothed belt by bending too sharply. The toothed belt is made out of a fiberglass cord webbing, that can be damaged by bending to sharply.

Never bend the toothed belt with a radius less than 25 mm.

The bend radius -r - on the toothed belt -2- must for this reason not be under 25 mm (approximately half the diameter of the toothed belt -1- on the crankshaft).

-- Install the toothed belt -1- on the crankshaft toothed belt sprocket -2- from underneath.
