Mercedes A-Class GRM (Gear Recognition Module) Gear Lever
This is a very common problem for the Mercedes A-Class (A168) 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. The fault will normally be intermittent but if it is left for a long period then it will become permanent.
