I can say that the CBS is totally B.S. After I had my first oil service at 2000 km CBS showed that 13000 KMs left for second oil service. Now I am at 5600 KM and its showing 8000 KMs left for the service. I visited the service and they reset the CBS nothing has changed. Service tech. advised me to change engine oil at every 10.000 KMs.
Now I am deciding to rely on my own CBS
Only parts to replace regularly is air filter, oil filter and engine oil.
First oil service at 10.000 KMs.
Second at 20.0000 KMs.
Third at 30.000 KMs.
and this will keep going on at 10.000 KM intervals. I will also change diff and transmission oil at every 30.000 KMs.
Nothing will hurt.
