Mercedes A-Class GRM (Gear Recognition Module) Gear Lever

 

This is a very common problem for the Mercedes A-Class (W168) A140, A160 & A190 with automatic transmission. The fault will cause the “F” light to appear on the instrument cluster and a jerky or clunky gear change. As the fault progresses this defect will also force the vehicle into limp home mode. The fault will normally be intermittent but if it is left for a long period then it will become permanent.
