Definite slow coolant loss 2019 40TDI 48k miles (1/3 litre over 250 miles). No visible signs of an actual leak. Checked oil filler cap, normal. Is this a common issue? Been advised not to put any of the propietory radiator sealant liquids in. Car still under extended warranty, would this be covered please. Any help appreciated
Have had a 4 month old 40TDI Black Edition for a couple of weeks now and this evening whilst out driving in Efficiency drive mode, the box kept switching to S gears from the expected E gears. After stopping and restarting engine E was auto selected again. Is this normal or do I have a fault already.
