Fuel sender unit

Hi
To my knowledge there's usually a plate bolted down either under the back seat or maybe in the boot/trunk if you locate and remove that it will allow you to access the sender unit for the fuel tank which the Micro filters are attached to, the sender unit usually unscrews anticlockwise or they can be bolted with several little bolts, be careful when removing the sender unit as there quite easy to damage
I hope this helps Nick

Hope you used factory sender. Aftermarket senders have contact problems. Audi updated their senders to gold contacts to improve performance. Moving it by hand may force good contact as opposed top free floating in tank
