OEM Part Number: 4G0919050A (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Hüco 132741 / Astemo 2503142

Accuracy note: Covers the Audi A6 (C7 2011-2018) as listed in the UK aftermarket catalogues. In-tank fuel pumps are sold two ways: as a complete feed unit (the pump in its swirl pot with the fuel-level sender and float) or as a bare pump that is fitted into the old housing, and petrol and diesel versions are not interchangeable — most diesels have only a low-pressure lift pump in the tank, with the high-pressure pump on the engine. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check fuel type, the plug pin count and whether your car has one sender or two (saddle tanks on 4x4 and some larger cars) against your VIN before ordering.

Fuel pumps / feed units (aftermarket)	Hüco 132741 (petrol feed unit with sender); Hüco 133142 (diesel feed unit with sender); Astemo 2503142 (diesel feed unit with sender); VDO 2803580184302 (petrol feed unit); Pierburg 7.02550.61.0 (bare electric pump, 3 bar, 1 connector, 7 A, without sender); Ridex 458F13815 (bare electric pump, 3 bar, 2 connectors); Metzger 2250674 (in-tank feed unit with sender, 10-pin).
Types & variants	Complete petrol or diesel feed units with sender versus bare 3 bar in-tank pumps that go into the existing housing; the 10-pin Metzger unit shows the C7 module carries more connections than the B8-era units.
Genuine (OE) numbers quoted	4G0919050A (Metzger 2250674)
Fitment notes	Petrol and diesel modules are separate parts, both supplied with the gauge sender, while the bare Pierburg or Ridex pump suits a repair that keeps the original swirl pot and sender.

Audi A6 Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Audi A6, few component failures are as inconveniently timed as this one — it has a habit of stranding drivers mid-journey rather than giving a clean warning while the car is safely parked. Knowing the early signs buys valuable time to get it sorted before that happens.

Before you buy: fuel pump specifications vary by engine size and fuel type, and petrol/diesel versions are never interchangeable. Always confirm against your VIN before ordering.

Audi A6 Fuel Pump: What It Does

The Audi A6's fuel pump draws fuel from the tank and delivers it to the engine at the pressure required for proper combustion. Almost all modern versions sit inside the fuel tank itself, submerged in fuel, which is partly why access for replacement is more involved than the part's small size might suggest.

Audi A6 Fuel Pump: Generations & Engines: Fuel Pump Type

Accuracy note: these are documented patterns by generation and engine family, not a substitute for confirming your exact engine code — always verify against your V5C before ordering, since petrol and diesel pumps are never interchangeable.

C6/C7 (2004–2018), 1.8/2.0/3.0 TFSI petrol	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
C6/C7 (2004–2018), TDI diesel (2.0/2.7/3.0)	Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump
C6/C7 S6/RS6 (2006–2018), V8/V10 petrol	Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine
C8 (2018–present), all petrol, diesel & S6/RS6	Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering

Confirmed: A Genuine, Massive-Scale Safety Recall Worth Checking Your Car Against — Audi A6 Fuel Pump

This is genuinely worth checking directly: a confirmed recall covering 1.2 million vehicles across this range addressed a genuine fire risk from a coolant pump that could overheat, caused by the pump becoming blocked by debris or moisture causing an electrical short. Audi's first attempted fix was a software update, which reportedly wasn't effective, meaning the recall ultimately required hardware replacement in two separate stages. It's genuinely worth checking your specific VIN against the official recall register and confirming both stages have been completed.

A genuinely useful inspection tip worth knowing if buying a used fuel pump: physically checking the electrical connector for melting or browning is a good way to spot a failing unit before buying it secondhand.

It's also genuinely worth knowing an alarming account regarding the belt starter generator on 48V mild hybrid models: one documented case saw this fail at just 47,000 miles, with Audi UK refusing a goodwill contribution and claiming the ignition had been left on, despite no diagnostic proof offered.
