DB9 Fuel Gauge not working...
Discussion
Sounds like a gauge failure. Not good news it that's the case. If it was a problem with the level sender I would expect the idiot light to come on.
Perhaps something might show up on diagnostics. If not, then I am guessing that it's all part of the same cluster and would cost megabucks to replace. There are specialists that can repair faulty clusters - I had this done in my BMW when the dealer wanted 600 quid for a new cluster. Ended up costing me £40.

to resurrect an old post.....
This weekend went to france.
Filled up, on the M25 (so maybe 20 miles later) fuel gauge fell to zero - no fuel light. After probably 20 mins back to normal.
In france, filled up - same as above.
Given that others have had this problem does anyone know what the fault is? Car is under dealer warranty etc. so I can make it there problem without issue, but wondered if anyone knew the cause.
I though faulty sender, but if that was the case would have expected the fuel light to have come on?

I had to get the sender changed on my vanquish which cost a fortune as the rear axel and suspension had to be dropped and tank removed. I have to say though the warning light came on each time. The fault started infrequently to start with but got worse and worse. I would definitely return it.
Happy New Year all!
Had this happen consistently on my car, every time I fill up to full, the gauge would drop to zero (but no warning light), then come back up after a while. Anyone had this look at or fixed? What was the outcome?
On another note, when the tank is filled to full, should the needle go all the to the top white mark? The few time I have filled to full, it always sits underneath the top mark. But when it drop to empty, it's always just below the bottom white mark.

i had a similar issue yesterday. the gauge registered empty tank, warning came up. this surprised me as had only done about 60 miles since last fill up.
went to fill her up asap and only took up 30 litres.
i have seen that this issue has been discussed before, but no real full guidance on location of faulty part, remedy, etc.
has any member tacked this issue?
cheers raj

Might be a bad fuel sender unit. Happened to me with my V8V:

thanks for the reply.
your write up mentions that it was a quick fix.
i am hoping so.
as i have read that that it requires the subframe to be dropped and petrol tank to be removed!!!
i have also read that it is work cleaning the contacts first.
cheers raj
I haven't poked around in a DB9's fuel tank, so I honestly don't have an answer for if it'd be different than it was with my Vantage. The Vantage's fuel tank is very easy to get into, though. Same tank layout for both cars, just not sure of getting to the access port at the top of the tank. On the Vantage, you only need to drop the rear subframe if you're removing the fuel tank. Hopefully you don't have to do that with the DB9!your write up mentions that it was a quick fix.

I've heard cleaning the sending unit's contacts can work. But it looks like the sending unit for the DB9 is pretty inexpensive, might be worth just replacing entirely if it's the problem. At that point, I'd decide based on labor rate.
