My fuel guage is displaying 0 - nothing.

did a scan with the vagcom and got :

so looked this up:

######
Possible Symptoms

Fuel reserve displayed value 0 (empty)

Possible Causes

Wiring between Fuel Level Sensor (G) and Instrument Cluster: Open or Short Circuit

Possible Solutions

Check Measuring Block Value
########

Where is the fuel level sensor ?
and how do i "check the measuring block value" ?

doubt the wiring is just going to fall over randomly, so presume maybe the unit has become faulty and ill need to change it? does the tank need to be dropped and drained for this ?

or is this an easy DIY job ?

i knew something else would go, been something every 2 months so far..
lovely

thanks

probably the sender in tank
you can get to them without taking tank out but needs to be below 3/4 full
unbolt the big plate 3 screws
then unbolt the sender/pump assy top to gain access

incidentally has started working again now.. i think something is obviously not quite tight if moving the car around has put it back in place.


excuse my ignorance, big plate 3 screws ? do i need to access this from the underside of the car, or is this somewhere under the back seats?

under back seat or boot carpet

anyone know where to source this part? or is it a seat/vw jobby?
