OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Bosch 0 580 200 392 / Astemo 2503134
| Fuel pumps / feed units (aftermarket) | Bosch 0 580 200 392 (complete in-tank pump module with level sensor, petrol, connector parts included); VDO 2910000152800 (fuel supply module, diesel, 12 V); Astemo 2503134 (feed unit, diesel); Astemo 2503292 (feed unit, diesel); Hella 8TF 358 304-911 (feed unit with sender, diesel, two plugs 4-pin and 3-pin); Pierburg 7.05656.06.0 (feed unit module, 4 bar / 58 psi, 13.5 V, 9.5 A, 227 mm long); ERA 775547A (in-tank pump, 5 bar / 190 l/h, 7-pin); ERA 775299A (feed unit, 4 bar / 110 l/h, 5-pin) |
|---|---|
| Types & variants | Petrol TFSI engines take a 4-5 bar feed unit (Bosch 0 580 200 392, Pierburg 7.05656.06.0, ERA 775547A at 5 bar / 190 l/h for the higher-output engines, ERA 775299A at 4 bar). Diesel TDI engines use a low-pressure in-tank lift unit with swirl pot and pre-filter (VDO, Astemo, Hella, Topran 630 679, Ridex 1382F0002 at 0.5 bar), and the Hella and Topran diesel units carry a separate lever-type level sender with 3-pin and 4-pin plugs. ERA 770202A (4 bar / 140 l/h) and ESEN SKV 02SKV277 are bare in-tank pumps. |
| Genuine (OE) numbers quoted | 1K0 919 051M (Kamoka 8400010) |
| Fitment notes | Petrol and diesel modules differ in pressure and plug layout, so match the engine code before ordering; a bare 4 bar pump can be dropped into the original petrol housing, but diesel owners usually need the complete swirl-pot unit because the sender and pre-filter are part of it. Astemo asks for the assembly information to be observed, and Hella specifies qualified fitting. |
Audi A3 Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Audi A3, few faults pick a worse moment to happen than this one, which has a habit of leaving drivers stranded mid-journey rather than failing safely at home. Catching the early signs gives you a genuine head start before that happens to you.
Audi A3 Fuel Pump: What It Does
On the Audi A3, fuel reaches the engine at the pressure combustion needs thanks to the fuel pump, which draws it straight from the tank. It sits submerged inside the tank itself, and that positioning is a big part of why replacement takes more effort than the part's size would suggest.
Audi A3 Fuel Pump: Generations & Engines: Fuel Pump Type
| 8L Hatchback/5-door (1996–2003), 1.6/1.8/1.8T petrol & 1.9 TDI diesel | 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 |
|---|---|
| 8L S3 (1999–2003), 1.8T 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 |
| 8P Hatchback/Sportback (2003–2012), diesel (1.9/2.0 TDI) | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| 8P Hatchback/Sportback (2003–2012), early 1.6/2.0 FSI 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 |
| 8P Hatchback/Sportback/Cabriolet (2003–2012), 1.8/2.0 TFSI (EA888 Gen 1/2) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8P S3 (2006–2012), 2.0 TFSI | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8P RS3 Sportback only (2011–2012), 2.5 TFSI five-cylinder | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8V Sportback/Saloon/Cabriolet (2012–2020), diesel (1.6/2.0 TDI) | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| 8V Sportback/Saloon/Cabriolet (2012–2020), small petrol (1.0/1.2/1.4 TFSI, EA211) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8V Sportback/Saloon/Cabriolet (2012–2020), larger petrol (1.8/2.0 TFSI EA888) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8V S3 (2013–2020), 2.0 TFSI | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8V RS3 Sportback (2015–2020) & Saloon (2017–2020), 2.5 TFSI five-cylinder | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8Y Sportback/Saloon (2020–present), diesel (2.0 TDI) | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| 8Y Sportback/Saloon (2020–present), petrol TFSI (1.0/1.5 mild-hybrid) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump — the hybrid system doesn't change this; the combustion engine still needs its own fuel pump |
| 8Y S3 (2020–present), 2.0 TFSI | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| 8Y RS3 (2021–present), 2.5 TFSI five-cylinder | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |

Confirmed: A Genuine Safety Recall Worth Checking Your Car Against — Audi A3 Fuel Pump
This is genuinely worth checking directly on front-wheel drive models from 2015 to 2020: a confirmed recall addressed a suction jet pump seal inside the fuel tank that could fail, allowing fuel to flow into the evaporative emissions system and potentially leak out through the charcoal canister — a genuine fire risk in the presence of an ignition source. Symptoms have included a noticeable fuel smell in or around the car, and difficulty refuelling, with the pump nozzle clicking off earlier than expected. It's genuinely worth checking your specific VIN against the official recall register directly, and worth knowing this recall does not apply to Quattro all-wheel drive models, since front-wheel drive and Quattro variants use genuinely different pump assemblies — worth confirming your specific drivetrain before assuming this recall applies, or before sourcing any replacement parts.
It's also genuinely worth knowing an alarming account regarding the belt starter generator on 48V mild hybrid models: one documented case saw this component 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 of this being offered.
