C5 Allroad Fuel problem


Registered User
I am about to look at an 04 2.5 A6 allroad

apparently the owner says there is a problem with the secondary pump or lift pump or the pump that feeds the main pump (any of that make sense!)

I am assuming its is an in tank pump, havent found a schematic yet but does anyone have any experience of this?
easy job?

The lift pump does little more than move fuel over the tank baffles.
If its a fueling issue its likely to be the main VP44 pump...
Look for 00550 fault codes. You will find a few posts on here...
No cheap solution......
Just my 10p worth....

As above, most likely a dead injector pump, if it's cheap go for it and have the pump rebuilt...

Then you need to change one of the pumps that transfer fuel from one side to the other...
