Fuel Gauge not functioning after filling to full

[spurs fan in a coupe]

Ok, I'll definitely take a look at the sender before buying a new one. I'm not sure how much gas is in my tank now, probably a bit less than half. How empty does it need to be to remove the sender without spilling any gas in the car?

It needs to be very low on fuel to avoid any mess

My lesson - don't top up. And if it goes wrong - wait a bit until it goes to below half a tank.
(That's not saying there aren't a host of other reasons that the most unreliable part is the Z3 can go wrong - tight competition with the OEM fan resistor pack)

What’s the OEM fan resistor pack problem?

One of the spot welds in the manufacturing process was defective and eventually the fan only works at the highest speed. It can be fixed by a bit of solder. Happens eventually on most cars (if you drive enough)

Is this for the aux fan ? I believe mine is always running, even immediately when starting the car up

No - the fan to the cabin
