Default Fuel gauge show empty

Hi

I have a 2006 2.7TDi. The fuel gauage shows empty, it happened quite quick, within an hour from 1/2 tank to need to refuel, so refuelled full tank, now shows totally empty, nothing there and stays like that, no change.

Audi dealer says fuel sender not working, need to replace fuel pump!!!, why is this?

cheers

I think they try to gyp you.
You only need to replace the Fuel Level Sensor, which actually is ON TOP of the fuel pump. I bet they will charge you for a "new" pump and will leave the old one in.
The level sensor has a floater that is not dependent in any shape or form of what the fuel pump does.
I don't think the TDIs (diesel?) have a much different fuel pump/supply.
If they do, I apologize for the wrong info.

It looks like nobody selling parts lists the 2006 2.7 TDI model.
Unless it is strange, it looks like the dealer has a niche with this model. Maybe that's the way the pump indeed comes as a "whole" unit, but I would really like to see it at the dealer.
Vagcat.com is also "mute" about this particular engine, so... I'm affraid you'll have to "trust" them.

I had the same problem in my 05 4.2. At least in the states Audi issued a TSB for 05 and 06 cars calling for a software update. If you want me to send you the TSB, which may save you the price of a fuel pump, send me a PM with your e-mail address and reference the gas gauge showing empty.

In the states the fuel gauge reading a false empty is common in the 2005 and 2006 cars. It turned out that the false reading was caused by a software issue, not the fuel pump. Audi issued a Technical Service Bulletin (TSB) on how to upgrade the fuel gauge software to fix the problem. It was done to my car, a 2005 4.2, a couple of years ago. I don't know if Audi had the same software problem in the UK.

For unknown reason, the fuel guage has started working again, after I re-filled the tank full again. Its been a couple of days and it is as normal, I am waiting for it to get to around 1/3 full when it last suddenly went down fast. I guess it still could be a problem with the fuel sender?

Same thing happened last night. Earlier in the day I backed the car out of the garage and parked it on an incline with the rear going downhill - no dash warning. About 10 hours later, started it up and immediately got a dash warning SERVICE with gas tank icon, fuel gauge on E, and miles left ZERO. After parking the car on level surface overnight gauge went to normal the next morning.
As with PO, there was approx. 1/3 tank of gas.

Hello Kevin, I have an Audi A6 2006 2.0 TDI, I had a similar fault the other day. Gauge dropped from Half to Empty. Filled the tank which was actually only half empty and is now currently showing full. Not sure if the error will still be there when it gets back down to half... Can you advise if the TSB Technical Service Bulletin was applicable to this model and could you send it me?

Here is a link to the TSB library that I created. You will find the fuel gauge TSB in the library.

Regarding the issue of the fuel gage. My wife completely drained the battery on our 2005 A6 3.2 one day. After jumping the car, the fuel gage showed completely empty despite it having 3/4 of a tank of gas. Day #3 after this problem, I filled up the gas tank full (just to make sure). After this I drove it around and the needle came off the peg and SLOWLY rose up to 100% full in a period of about 45 minutes of the car running. No issues since. Very strange...

Default Try using decent Diesel

I had this problem after filling up at a super-market. I switched to Murco and it started working again, then Shell was working for me for a few months although the unit has just stopped again, I do recall it first got triggered going up a very steep hill with a full tank. I am going to try some BP and let you know how I get on....
