Another (other) fuel gauge problem. (And volt gauge.)

[M3 Compact]

Search reveals several gauge/cluster issues, but I haven't found one that replicates mine.

2005 A6 1.9 Tdi Avant Sport manual 6-speed....



Fuel gauge is consistently registering 1/4 of a tank more than it actually holds, but the warning light/buzzer works correctly.<- So I'm assuming it isn't sender unit related.

It's wedged right up when genuinely full and the light comes on when registering/displaying 1/4-1/2 a tank. It's been like this for 12 months/25K miles.

The volt gauge recently started wedging itself at the top of the display too, while running. It drops down to approx 1/4 when switched off, but takes a few seconds before dropping to the bottom and any electrical use sends it back up to approx 1/4.

It's as if both gauges are displaying approx 25% 'more' than they should....

I'm guessing at a cluster fault?

VCDS here tomorrow to tackle my A4 cruise activation problem. Any point in checking the A6 with VCDS???

TIA.

Simon.

Hiya mate, think it's a common cluster fault...
