Replacing Solar Rain/Light Sensor And Condensation Sensor

IMPORTANT: Read and comply with notes on protection against electrostatic damage NOTES ON ESD PROTECTION (ELECTRO STATIC DISCHARGE).

Necessary preliminary work:

• If necessary, remove interior rearview mirror.

For equipment specifications up to 09/2009:

• without 2-zone automatic air conditioning (optional equipment 534)
• without 4-zone automatic air conditioning (optional equipment 4 NB)
• with Head-Up Display (optional equipment 610)

From 09/2009 onward, considered standard equipment and thus not dependent on equipment specifications.

Disconnect plug connection (2).

Unlock metal spring (3) in direction of arrow.

Remove solar rain/light and condensation sensor (1) from windscreen.

Installation note: Close plug connection (2) only after fitting solar rain/light and condensation sensor on windscreen! Carefully clean windscreen in the contact area with the solar rain/light and condensation sensor! Remove all silicone residues.

Fig. 333: Unlocking Metal Spring

Remove protective cover from the new solar rain/light and condensation sensor. The silicone-coated surface below it must not be touched! Press metal spring (3) centrally to ensure that there is correct engagement in both hooks (5) on every side of the retaining element (4).

NOTE:

• Solar rain/light and condensation sensor is automatically coded by junction box.
• Carry out initialization to calibrate the rain sensor to the windscreen.

VEHICLE PROGRAMMING AND CODING

NOTE:

• In order to avoid incorrect programming procedures and error messages, it is essential when working with the ISTA/P programming system always to use the version.
• Battery voltage must not drop below 13.0 V during programming. Connect battery charger prior to programming
  Use only BMW-recommended battery chargers*
  *Sourcing reference BMW Workshop Equipment Catalogue

Programming sequence via ISTA/P:

• Identify vehicle and read out control unit data
• Draw up and configure measures plan
• Prepare programming, export CBS/CKM data
• Carry out repair measures, replace control units if necessary
• Identify vehicle again after repair. Update measures plan
• Carry out programming
• Assess programming afterwards, import CBS/CKM data
• Programming successfully completed
