hi guys,
I'm new to this site and recently bought a a2 for my wife, which I have to say was a good idea. We are saving on fuel cost significantly compared to our former bmw 330i....

However, I have a huge issue. If I fill the tank up, the fuel meter shows the capacity filled, which is great... you drive a little while and the gauge shows EMPTY....then it goes back to normal, and somtimes it moves from empty to full...

Strange!! Today it is perfectly fine driving in to work.... any help guys and advice is really appreciated???


Ok, so now I can read it.

Replace the complete unit with one from a breaker's, it will be a *lot* cheaper. Check first the VAG-Com, though, it should tell you if there's a sporadic connection.
An FSI tank sender will not do if it's a 1.4 as the sensor values changed at some point in 2003. If it's a diesel, just replace and away you go.
Disconnect the battery before you do it. The tank is under the RHD rear seat - take the seat out and turn the black plastic cap.

thanks`

wicked....i was not aware that such part can be found easily... so before attempting the breakers yard, shall i verify the connection? and exact sensor? once i have established, then go and hunt for one at a breakers?
 
Something like that, yes. Check the connectors first and see if someone will read it with Vag-Com-

I think the sensor and pump is one unit, I'm not 100% sure.
