Removal

1. A mechanical cable is not used with the LCD instrument panel; the electrical sender bolts onto the gearbox in the same position as the conventional cable.

2. To renew a mechanical cable, first disconnect it from the speedometer head. If it is not possible to reach up behind the instrument panel, partly withdraw it (see illustration).

3. Working under the bonnet, free the cable grommet from the bulkhead and draw the cable into the engine bay. Recover the grommet.

4. Undo the knurled nut which secures the cable to the transmission (or trip computer speed sender, when fitted). Remove the cable.

Refitting

5. Refit in the reverse order to removal. The cable must not be kinked or made to bend sharply. If lubricant is applied to the inner cable, do not put any on the top 15 cm or so, in case it gets into the speedometer head.
