Extent of work
At every inspection, the CHP will be reviewed in accordance with optimal defined diagnostic routines.
In addition, basic maintenance work such as renewing the spark plugs. All necessary materials and labour costs other than oil and coolant are included – the disposal of used oil and oil filter is also included. On new spare parts you get 12 months warranty, if it is not subject to wear.
The individual steps can be found in the following table.
