Instructions on replacing steering angle sensor - Vehicles before Mod. '03: Notes

As from model 2003 (3 range) there is a new steering angle sensor -C2-  installed. This internally modified steering angle sensor -C2-  is distinguished (externally) from previous steering angle sensors -C1-  by the plug connection being larger and in a different position. New steering angle sensor -C2-  : axial plug connection (below steering shaft); previous steering angle sensor -C1-  : radial (side-mounted) plug connection.

• In the event of replacement, the new steering angle sensor -C2-  can be installed retroactively instead of the previous version-C1-  .
• When installing the new steering angle sensor -C2-  for the first time in vehicles before model 2003, because of the modified plug connection (larger plug, position of plug and modified pin assignment), a new cable guide -B2-  (instead of the old cable guide) together with an adapter lead -E2-  must be fitted.

• The old cable guide -B1-  is distinguished from the new cable guide -B2-  (series implementation as of 2003 model) mainly by the cable rerouting at the end. The cable duct (ribs) of the new cable guide -B2-  are for laying the lead in sections (ribs in old cable guide -B1-  are uninterrupted).

• The adapter lead -E-  is inserted between the new steering angle sensor -C2-  and the existing (previous) lead -X-  . Next the joined leads -X  and E-  together with the plug connection are inserted in the cable duct of the new cable guide -B2-  and fixed with a tie-wrap (-arrow-  in Fig 4 ).
