That's rather bizarre. Is this the 'issue' which has been the subject of the recall for the D5 to update the software ? If so, I assume (for some reason) it does not affect the D4. The problem with this advice is that it goes against the 'advice' given by the display which asks if you want the system to search for the nearest filling station when you reach ONE bar.
Is there a link to this advice or was published in a TJ ?
The return feed into the spill compartment certainly explains my earlier problem with my V50 when 5 litres was insufficient to 'refresh' a near-empty tank.
