Fuel Consumption CVT resetting

If you have replaced the battery, sparkplugs, EGR valve, or even recharged the battery, the CVT Module loses its settings and you start to burn twice as much fuel. The only way to solve this is to reset the CVT by either the computer at the dealer or following the below procedure. My milaege dropped from 11 litres per 100km to 6 litres per 100 km all of a sudden once I did the below procedure. I assume this is a flaw in the CVT module which loses its settings everytime you disconnect the battery.


Thanks to CVT!
1. Start the car and run it to operating temp (no other electricals must be used like aircon, radio, power windows, mirrors, lights). Keep the doors closed so that the dome light is not on.
2. Shut down the engine
3. Start engine again and turn on headlights, without operating any other electrical load (other than headlights).
4. From P(ark), shift to N, D, S, L, S, D, N while waiting at least 2 seconds before shifting to the next position
5. Repeat the N, D, S, L, S, D, N sequence for 3 times
6. Turn-off headlights
7. Shutdown engine
8. Drive and investigate if the fuel consumption decreases.
