LAMP SETTING ON AN AUDI A8 4.0I TFSI QUATTRO
Important safety note
The following technical information and practical tips have been compiled by HELLA in order to provide professional support to vehicle workshops in their day-to-day work. The information provided on this website is intended for suitably qualified personnel only.
STEP-BY-STEP INSTRUCTIONS
Vehicle and work preparation
The Audi A8 is first parked on the prescribed lamp setting station and then prepared.
Such preparation entails the vehicle being visually inspected and a battery charger connected.
Positioning of the SEG
The next step is to position the SEG in line with the lamp. Information on SEG IV: Positioning is assisted by aiming the laser pointer at the light source.
Reading and setting the forward inclination
Reading the forward inclination
SEG IV - setting the forward inclination
The required forward inclination setting is read off the headlamp on the Audi A8 and set accordingly on the rotary control knob on the SEG IV. The forward inclination is set on the digital SEG V when selecting the vehicle model (see our practical example on the BMW 5 series).
Low beam test
SEG IV
SEG IV - result
SEG V - result
The low beam is measured first. The result can be read on the scale (SEG IV) or on the digital display (SEG V). In the example, the result is OK in each case – see our information box for a description of deviating results.
High beam test
SEG IV
SEG V
The high beam is measured accordingly. This is initiated on the SEG V via the display. The result of the high beam test is also error-free in our practical example.
PRACTICAL TIP
The SEG IV also makes it possible to measure lux values and thus check the glare effect.
Completion of testing
SEG V
Once the two main light functions have been checked, the measurement procedure is complete. With the SEG V, the results can be saved for later retrieval. The measurement for the other side of the vehicle is carried out in the same way.
What to do in the event of deviations?
Our example image shows the low beam set too low, using the SEG IV scale as an example. The lamp setting must be accordingly corrected.
