Car just died on me

2006 Audi A6 3.2, 150 000km, original fuel pump AFAIK.

Was driving home yesterday, with cruise control on at 80 km/h and the car just died and the EPC light came up.
Motor will crank and sort of fire but won't keep going.
I got it towed home ( thankful only about 4 km away ) and busted out the VAGCOM cable and software to see whats going on.
I found 3 fault codes. Saved them, cleared them and tried to start...same thing.
It looks to me that the fuel pump has failed.
No Audi dealer within 200 km of me and I don't think I'd get them to do it anyway.....

Local VW dealer is not interested...weird....

I cannot hear the pump when I turn the key on and don't recall if i should be able to to or not? I never took any notice.....

Anybody know if the tank has to be dropped to change the pump?
I should be able to change it myself, except not keen on laying on the ground to do it....lol

Anybody know of a good source for a new pump, besides Audi? Not sure our local autoparts store would be much help.

Steve

It could be fuel pump failure/fuel pressure regulator clogged or fuel filter.

Check for any Leake in fuel line.
Check when was fuel filter replaced.
If fuel pressure regulator is old replace it.
Have your high pressure fuel pump checked.

I will start with fuel filter.

Aah...

From the last code it looks like fuel pump is creating the Drama mate.

Check the fuse first and then fuel pump.

I checked the fuel pump fuse: ok.
Each time I turn the key on I can hear a faint buzz for a second near the tank. I gave the fuel tank a bit of a thump, and the car started.
I guess that is the problem and needs changing.
Are there 2 fuel pumps on these cars? A LP pump in the tank and a HP pump in the engine bay?

Steve
 
Yes you do have a LPFP in the tank. It's a easy removal and install. OEM part no 4F0919087F.
 
Got the car taken to a local mechanic a few days ago. They are having problems finding a new one. Had one sent from E/States and its wrong....

Quote from Audi was ~$730 and its on backorder anyway.
messaged Lintrex in Perth...no go....
Mechanic is waiting for replay from Pace. ( not sure where they are....)

Anybody got a good source for things like that?
Can see them in the US, but not sure if thats an option. (postage )Have emailed Europarts in NJ to find out.

Still waiting to hear.....One of those *may* work....listing says it fits one version of the A6. 'AUK' is in my VIN so it should work.
I might need to get a pic of the old pump to compare.

No car...feel like my throats been cut....lol
Steve
 
They had a car model picker on ebay for the VDO pump I just had to guess which variant yours was. Looking at the compatability table on the listing it covers pretty much all A6 variants from 2005 to 2011.

Mechanics finally admitted defeat.....so I have to buy one myself.

Thanks for th Europa tip. I bought that one. Postage was $105US but it still came out at half the cost than if I bought from Audi. Got a fuel filter as well.
Coming via Fedex so should get here quick. We will see.

Thanks or your help guys.
 
The FP from Europarts arrived yesterday and my wife had time to take it around to the mechanics the same day.
I was a bit nervous whether it was the right pump as it came from the US and would cost alot to send back. Not to mention more time off the road....
I cracked and rang the mechanics to find out. It was the correct one and my car was ready...woo hoo.
Thanks for the heads up on Europarts and the correct pump part number guys. Pump was $219 US but with exchange rate and FexEX ( eek! ) it came to $530 AUS. Still cheaper than Audi but still spendy....
I bought the old pump home to pull it down to see what was the cause of stopping. Not gone in yet.It looks like it would be easy to just replace the pump itself and then have a spare assembly.
Not sure I would need one though...who knows. Also other parts may have aged and be ready to fail...
