Model Year:
As of 2020 up to 2022
Equipment:
Fuel tank, 90-liter (M–no. 0I2)

If this is the case, it is not possible to rule out any perceptible noises due to the low relative movement of
the fuel tank.
Action required: Check retaining strap for fuel tank and replace it if necessary, depending on the result of the check.
Information

retaining strap.
Therefore, please order a retaining strap only if not OK.
