Renewing gas discharge bulb
  WARNING
t  Within the glass bulb of a gas discharge bulb, pressure can range from between 7 bar (cold) and 100 bar (hot). Temperatures can reach up to 700 degrees Celsius on the glass bulb.
t  Should the glass bulb explode, there is a risk of injury from burning.
t  The use of protective gloves and goggles is compulsory when removing and installing gas discharge lamps.
  Note
t  The left-hand side gas discharge bulb -L13- and the right-hand side discharge bulb -L14- can be checked through the control diagnosis of the onboard supply system -J519-.
t  The figures show how to change the left gas discharge headlight lamp.
t  Replacing the right gas discharge headlight lamp -L14- is done the same way.

  Caution
t  When fitting the gas discharge lamp , be careful not to touch the bulb with fingers. Greasy marks left by fingers on the bulb will evaporate on switching on the gas discharge lamp. Then the bulb will become opaque.
t  Do not apply mechanical force to the glass bulb of the gas discharge lamp . The glass bulb is extremely sensitive and is also under a high internal pressure.

–  When positioning the retention ring -arrow-, ensure the retention tabs -1- are housed correctly and interlock the two parts.
  Note
Do not look directly into the light beam; UV light beams from gas discharge bulbs have approx. 2.5 times more power than halogen bulbs.
–  Check headlight functions.
–  Check headlight setting and adjust headlight as necessary → Booklet101.
  Note
If you remove or adjust a headlight with a gas discharge lamp to the bodywork, after assembling or adjusting it again, you always have to readjust the headlights. → Booklet101.
