Default Sender or Cluster?

Since this summer, my gas gauge has been reading off, and it has been progressively getting worse.
It stays full, when the tank is not.

Today, the 'Low Fuel' icon came on with the gauge reading one-half tank.
Trip computer 'miles to empty' was accurate at 25 mi.

I'm thinking this is a sender problem, not a cluster problem.
But then why do the icon and trip computer read correctly?

Default do you have a vag-com? do an automatic scan of all the modules...

and if it's a sender problem it'll show (most likely is).

Default Cluster

After having the exact same problem you've described happen twice, it's been the cluster and not the sender that's been the problem. I am currently having the same problem again and am probably just going to leave it be. Buying a third cluster seems ridiculous at this point. As you said, the trip computer works and I haven't run out of gas yet.

Default When i replaced my cluster the first time>>>

the fuel gauge was doing what you described Jeff, but my trip computer was off too....so that's weird....

I would bet on cluster too...one reading is correct..so i would go with that.

Default I'm not sure about this but:>>

is the "low Fuel" sensor the same as the fuel level sensor? Usualy they are not, but again, I'm not sure. Would be great to check on the Bentley but I don't have it at work.

Default Audi's position will be that is an anti- theft feature...

The thieves will run out of gas at 1/4 tank and only the lucky owner knows the secret.
This happened to me for the 3rd time yesterday.The final fix is printing out a label that says "tank is empty at 1/4 mark"
Cheers!

Default Cluster...>>

Same symptoms here. Does you gauge go to zero when you turn the engine off? If so, does it bounce up a quarter when you open the door and the cluster date/miles gets repowered for a moment? Mine did.

Cluster replacement solved it, for now. But with others' experience I am somewhat hesitant to assume this is fixed permanently. It's strange that the miles-to-empty has always been accurate. That has to get the fuel level from somewhere, how else would it know when the tank was refilled? So I've always assumed the fuel level sensor was Ok and the gauge was whacky.

Default First thing I would do is take out the cluster, and reconnect the 3 connectors on the back..

Just unhook, clean and reconnect and see what that does for you..
