Skoda Felicia Headlight Adjustment

[simonsheil]

A common problem with the Skoda Felicia is the loss of the internal adjustment on the headlight system and the aim being too low with insufficient adjustment on the thumbwheels to correct this leading to an MOT fail.

This is caused by the loss of hydraulic fluid from the headlight adjustment system which can only be remedied with the replacement of the whole system.

An alternative to this is to alter the adjustment mechanism so that the thumbwheels adjusters can be used. The headlights can then be adjusted using the thumbwheels which are fitted to the top of each side of the headlight unit. The outer ones alters the headlight beam vertical aim and the inner ones the horizontal aim.

The photo shows the back of the left hand headlight and the various adjusters. The right hand side is a mirror of this although to gain access you will need to unclip and remove the top of the air filter.



The next photo shows the adjuster mechanism removed. It is held in place by a bayonet style clip so simply twist and pull out of the headlight to remove. To allow more adjustment on the thumbwheels the nut need to extend further form the adjuster.



If you simply try to unscrew the nut it may turn the internal of the adjuster at the same time. To prevent this pull the nut in one hand while holding the adjuster in the other. You may need to grip the nut with pliers to do this. Then with your third hand clamp the plastic with another set of pliers. You can now simply unscrew the nut. Once you have unscrewed it put the adjuster back in the headlight and see if the adjustment is within range. If not simply remove and unscrew the screw a little more.
