OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 986 580 832 / Astemo 2503546

Accuracy note: Covers the Audi A1 (8X 2010-2018) 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)	Bosch 0 986 580 832 (in-tank fuel pump / feed unit, petrol, no pressure or flow given); Hella 8TF 358 106-431 (complete feed unit with sender and gasket, 5-pin, no built-in pressure regulator); Astemo 2503546 (complete feed unit with sender, diesel); Pierburg 7.07795.41.0 (bare electric pump motor, 0.5 bar, 12 V, 5.7 A, 229 mm long, 2 connectors — a pre-supply/lift type pump); Delphi FG2423-12B1 (feed unit module without pressure sensor, 266 x 108 x 123 mm); Meat & Doria 77007 (feed unit module, 4 bar); ERA 775299A (feed unit, 4 bar / 110 l/h, 5-pin, blue housing); ERA 770202A (bare in-tank pump, 4 bar / 140 l/h, 12 V)
Types & variants	Petrol cars take a 4 bar swirl-pot feed unit with the level sender built in (Hella, ERA 775299A, Delphi, Meat & Doria), or a bare 4 bar in-tank pump (ERA 770202A, Bosch) if only the motor has failed. Diesel cars use a low-pressure lift unit at around 0.5 bar (Astemo 2503546, Ridex 1382F0110, Pierburg 7.07795.41.0) because the high-pressure pump sits on the engine. The Delphi FG2423-12B1 and FG2498-12B1 modules are supplied without the pressure sensor.
Genuine (OE) numbers quoted	1K0 919 051M (Kamoka 8400010); 1K0919051AE (Meat & Doria 77007)
Fitment notes	Check petrol or diesel first, as the two feed units are not interchangeable; the bare ERA 770202A or Pierburg motor can be fitted into the original housing when the sender and swirl pot are sound, but a full module with sender is the safer fit if the fuel gauge reads erratically. Hella notes the unit has no system pressure regulator and should be fitted by qualified personnel.

Audi A1 Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Audi A1, this particular failure has a knack for terrible timing, stranding drivers mid-journey instead of giving fair warning while the car's parked up safely. Spotting the early signs early enough is what stands between a routine fix and a roadside breakdown.

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 A1 Fuel Pump: What It Does

Getting fuel from tank to engine at the correct combustion pressure is down to the fuel pump, and on the Audi A1 that pump sits inside the tank, submerged in fuel. That location is exactly why swapping out such a small part is rarely a quick job.

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.

8X (2010–2018), 1.0/1.2 TFSI (EA211)	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
8X, 1.4 TFSI (various power outputs)	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump
GB (2018–present), 1.0/1.5 TSI	Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Audi A1 Fuel Pump

Audi has issued confirmed recalls on related models covering a coolant pump fire risk affecting 1.2 million vehicles across the range, and a separate fuel tank suction pump seal recall specifically on front-wheel drive models. It's genuinely worth checking your specific VIN against the official recall register directly.

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, where a documented failure at just 47,000 miles was met with a refused goodwill contribution from Audi UK.
