Audi A4 Fuel Pump: Specs, Fitment & Common Faults
Confirmed: a genuine, massive-scale recall covering 1.2 million vehicles addressed a fire risk from an overheating coolant pump — Audi's first attempted fix, a software update, wasn't effective, requiring hardware replacement in two stages.

| Types & variants | On the B8 the split is petrol in-tank feed unit versus diesel feed unit, plus a separate diesel in-line pre-supply (lift) pump and a bare 5 bar pump that fits into the existing swirl-pot housing; the diesel modules are the ones quoted at 206 mm with a metal housing. no pre-supply pump is listed for the B9. |
| Genuine (OE) numbers quoted | 1K0 919 051 BE (Kamoka 8400057); 1K0919051BG (Kamoka 8400060); none quoted for the B9 |
| Fitment notes | Petrol B8 and B9 cars use an in-tank feed unit that may or may not include the gauge sender, so check which the old unit carries before ordering; B8 diesels have a tank module plus an external lift pump and the bare Pierburg or Magneti Marelli pump can be fitted into the original housing. |
Audi A4 Fuel Pump: A Part That Fails at the Worst Possible Moments
Rather than failing conveniently while parked, this component on the Audi A4 tends to give up mid-journey, which is about the worst possible moment. Learning to recognise the early symptoms is the best defence against being caught out.
Audi A4 Fuel Pump: What It Does
The Audi A4's fuel pump function — pulling fuel from the tank and pressurising it for the engine — is straightforward, but its usual location isn't: it sits submerged inside the tank itself, which is precisely why access for replacement is more work than the part's size suggests.
Audi A4 Fuel Pump: Generations & Engines: Fuel Pump Type
| B5/B6/B7 (1994–2008), 1.8T/2.0 FSI petrol & 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 |
|---|---|
| B6/B7 S4/RS4 (2003–2008), 4.2 V8 | 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 |
| B8 (2008–2015), 1.8/2.0 TFSI petrol (EA888) | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| B8 S4 (2009–2016), 3.0 supercharged V6 & B8 RS4 (2012–2015), 4.2 V8 | 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 |
| B8/B9, TDI diesel (2.0/3.0) | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| B9 (2015–present), 2.0 TFSI petrol & S4/RS4 | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |

Confirmed: A Genuine, Massive-Scale Safety Recall Worth Checking Your Car Against — Audi A4 Fuel Pump
This is genuinely worth checking directly on 2013-2016 models: a confirmed recall covering 1.2 million vehicles addressed a genuine fire risk from a coolant pump that could overheat, caused by the pump becoming blocked by debris in the fluid or moisture causing an electrical short. It's genuinely worth knowing that Audi's first attempted fix for this issue was a software update, which reportedly wasn't effective, meaning the recall ultimately required a genuine hardware replacement carried out in two separate stages — first with a like-for-like replacement pump, then again later with an entirely new pump design once it became available. It's genuinely worth checking your specific VIN against the official recall register directly, and confirming both stages of this recall have actually been completed on your specific car, rather than assuming an initial visit covered everything.
It's also genuinely worth knowing an alarming, honest account worth being aware of regarding the separate 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. The owner reported similar experiences documented across several other models in the range — worth persisting with an escalation, potentially through the Motor Ombudsman, if you encounter a similar refusal without clear supporting evidence.
