2. Rattling / scratching noise on load changes during no-load operation
The noise only occurs briefly. After driving for a short period to warm up and with light changes between coast mode and traction in 1st and 2nd gear, the noise is clearly audible. In the case of vehicles with petrol engines at 5000 rpm and with diesel engines at 4000 rpm. The noise only occurs briefly.
