What changes
Transmission 02, adaptation 218D = 00. The gear number is shown only in S; in D it is just 'D'.
Details
Transmission adaptation 218D (ZF 8HP automatic and S tronic): what the cluster shows in D and S. Values: 00 in S only, 01 in D only, 02 in D and S, 03 never. The parameter itself is confirmed for A4 B9, Q5 FY, Q7 4M and A6 C8, but the mapping of numbers to variants comes from a single source so far, so check the result on the cluster. Some gearboxes do not accept the parameter — a3c then refuses before writing. To restore the previous value, roll back from the history.
Other options
This is one option of the “Gear number on the cluster” setting: only one can be active.
