Had mine for a few months now but last week or so it has been revving much higher in 1st and 2nd gear before then moving up the gears.

A definite change from normal.

What could be causing that or is this a common electronic fault e.g. the ECU needs to tell the auto gearbox to change at lower revs?
Many thanks

On my L322 ( basicaly the same engine and gearbox) it holds revs longer during warmup and while going up hills at slow speed. The official explanation for the former is to get the engine up to temps quicker but seeing as how engine temp is governed by load rather than revs I have a theory it's to keep oil pressure ( i.e flow) up during low rev/ high load situations. 2012 TDV8 Vogue (L322)

Has anyone else been driving it, or have you towed anything heavy recently?

My old D4 did this after I started towing a large caravan. It felt like it had over-compensated and it took a few months for the adaptive box to level itself out. FFRR SDV8 Autobiography
