Audi Q3 Fuel Pump: Specs, Fitment & Common Faults

On the Q3, Audi has genuinely issued confirmed recalls on related models covering a coolant pump fire risk and a fuel tank suction pump seal.

Generation covered: this guide is for the third-generation Q3 (F3, 2018–present), with particular focus on 2018–2023 registered examples now old enough for parts to be a common search. Check your logbook or VIN if you're unsure which generation you have.

OEM Part Number: 5QA919050C (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Hüco 132799 / Astemo 2502799

Accuracy note: Covers the Audi Q3 (F3 2018 on) 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 132799 (diesel feed unit); Hüco 133529 (petrol in-tank feed unit with sender); Astemo 2502799 (diesel supply module); Delphi FG2698-12B1 (feed unit, without pressure sensor and seal, 0.95 kg); Meat & Doria 771078 (feed unit); ERA 775722A (feed unit pump motor, 12 V); Ridex 1382F0461 (diesel feed unit, 4.5 bar, 4-pin, right-hand fitting); Metzger 2250576 (feed unit with sender, 4.5 bar, 7-pin).
Types & variants	Diesel supply modules (4.5 bar, 4-pin, right-hand side) versus petrol feed units with sender; the ERA and Vika items are bare pump motors for the existing housing; no pre-supply pumps are listed.
Genuine (OE) numbers quoted	5QA919050C (Meat & Doria 771078)
Fitment notes	Diesel and petrol modules differ, the diesel unit fits on the right side of the tank, and only the bare pump-motor listings can be fitted into the old housing.

Audi Q3 Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Audi Q3, there's rarely a convenient time for this to fail — it tends to strike mid-journey rather than while the car's sitting safely on the drive. Knowing what the early symptoms look like buys valuable time to get ahead of it.

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 Q3 Fuel Pump: What It Does

The job here is simple in principle — draw fuel from the tank, deliver it to the engine at the right pressure — but the Audi Q3's fuel pump sits submerged inside the tank, which makes physical access for replacement far more involved than the small part itself implies.

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.

8U, 1.4 TFSI & 2.0 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

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Audi Q3 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.
