13 54 ... Supplementary work for basic throttle setting (S62)

2013 Mini Cooper Countryman, Standard TransSECTION 13 54 ... Supplementary work for basic throttle setting (S62)
WARNING: This page is about a different car, the 2003 BMW Z8, 2002 BMW Z8, 2001 BMW Z8, and 2000 BMW Z8. However, it is still accessible from the selected car via links, so may be relevant.

This work is carried out:

  • on engines with adjustable pull rods at both cylinder banks
  • if the throttle opening of 24.2 mm +/-0.5 mm cannot be achieved when the full-load adaptation stop is set

The non-adjustable pull rod (1) of cylinder bank 1-4 is replaced by an adjustable pull rod (2) (versions as on cylinder bank 5-8).

Clip in adjustable pull rod (2) of cylinder bank 1-4 on throttle side only.

Clip in adjustable pull rod of cylinder bank 5-8 on throttle and servomotor sides.

Turn back stop screw (1) a few turns.

This ensures that the stop screw does not influence the servomotor-side stop.

Activate servomotor at specified value 100 % and check whether measurement (A) = 24.2 mm +/- 0.5 mm is achieved.

If measurement (A) > 24.2 mm +/- 0.5 mm, shorten pull rod of cylinder bank 5-8 by turning hexagon (1) until measurement (A) = 24.2 mm +/- 0.5 mm is achieved at all throttles 5-8.

Activate servomotor at specified value 0 %.

Synchronizing cylinder banks with each other: 

Position adjustable pull rod (1) of cylinder bank 1-4 on servomotor side on ball head.

Turn hexagon to adjust length of pull rod (1) so that ball socket is aligned centrally to ball head.

NOTE: Do not clip in pull rod (1) yet.

Force off adjustable pull rod (2) of cylinder bank 5-8 on servomotor side.

Position dial gauge plates on throttle body of cylinders 2 and 3 and throttle body of cylinders 6 and 7. Mount dial gauges in dial gauge plate supports for measuring at throttle bodies 3 and 6.
