Autodata Technical Issue 29 – Difficulty selecting reverse gear in 2012 Mercedes-Benz Citan

30 August 2019

Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This month, the cause of a stiff, creaking gear lever in a Mercedes-Benz Citan is resolved.

Q. We have a problem on a customer’s 2012 Mercedes-Benz Citan. It is difficult to select reverse gear and the gear lever creaks when changing from 5th to 6th gear. We have checked the gear change cables and they operate smoothly. We suspect the clutch assembly may be at fault, but it seems to be working correctly in all other areas. Have you any ideas on this fault before we go ahead and remove the transmission?

A. We are aware of a reverse gear selection problem that applies to all Citan models with transmission code 700.720. The cause is contact between the gear lever mechanism and gear lever trim panel. Remove the gear lever gaiter. Modify the gear lever trim panel by cutting off the area (Fig 1).

Ensure any plastic swarf does not fall into the gear lever mechanism. Refit the gear lever gaiter and confirm the problem has been resolved.
