Hallo Zusammen, seit Montag bin ich stolzer Besitzer eines Qashqai +2, 2.0 tekna mit CVT-Getriebe.
Das Auto macht mir wahnsinnig spaß, allerdings "schaltet" die Automatik sehr kreativ, bei gleicher Fahrgeschwindigkeit und leichter Beschleunigung geht die Drehzahl mal deutlich hoch, beim nächsten mal nur minimal. Das ganze wie gesagt in gleicher Situation. Ich hatte auch nicht versehentlich auf manuell gestellt.
Nun meine Frage, gibt es die Möglichkeit, das Getriebe zu resetten? Im Netz habe ich nur was vom Micra gefunden und weiß nicht, ob es funktioniert. Laut meinem Händler habe ich die aktuellste Softwar auf dem Steuergerät.
Die Anleitung, die ich vom Micra gefunden habe, hänge ich mal hier dazu, ich habe sie in einem englichen Forum gefunden und hoffe, dass ich es hier dazu machen darf.
"a) CVT Memory Reset:
1) Start the car and wait until the temperature is normal (Cold Temp light off if fitted with one).
2) Do not open the radio (On Nissan Connect turn the volume all way to mute) or other electrical equipment (such as headlights).
3) Pull the handbrake up and hold until the end of the process (Don't need to hold it... just lock it on).
4) Press the brake pedal and keep it pressed till the end of the process.
5) Move the gear to the "N" position for 2 minutes (use a stopwatch and allow 2-3 seconds overtime).
6) After 2 minutes (and few seconds), move the gear to position "D" for 1 minute (and few seconds overtime).
7) End the process.
8) Turn off the car or drive away... anything you wish
At the end of this process the CVT TCU will have the factory settings, and will drive as it was new. The factory settings are based on the lowest RPM while driving, for the best fuel consumption.
I have tried this "Memory reset" and it worked like a charm. The fuel consumption is back on normal and the car feels like new (with a torque feeling around 3000 RPM ).
b) CVT Re-calibration:
1) Start the car and wait until the temperature is normal (Cold Temp light off if fitted with one).
2) Turn off the engine and start again.
3) Turn on the headlights.
4) Press the brake pedal and move to the "N" position .
5) Move from "N" to "D" to "L" then back to "D" and "N"
6) Repeat step 5) for 3 times with a tempo shift of 1-2 seconds.
7) End the process.
8) Turn off the car.
I haven't tried the Re-calibration yet because I didn't disconnect the battery till now.
How to verify if the CVT Memory did reset properly:
When driving away from a stand, on the first acceleration input the car will rev to about 2000 RPM and at around 20 kph the revs will drop to around 1000 - 1300 RPM and stay there till 50 kph, when the revs will slowly increase. The feeling will be like an engaged clutch and not as a slipping clutch as it was before. Also while driving and accelerating on a road, the car must feel "Torque" and the RPM should not rise fast, but the speedometer should show an increase in speed. Always when you press the acceleration after a brake, the RPM will rise, but after 1 second will fall a bit (200-300 RPM). If there is no fall, then a Memory reset is in need."
