- Perform test step 29
1) The Tiptronic Switch -F189- receives its tiptronic gate recognition information or tiptronic up- and down-shift information via
the large magnet which is mounted on the lateral gate cover of the gate cover. If the switch has become detached, the gate
cover must be replaced.
