Fuel pump failure on the 2006 Audi A4
When fuel pump failure gets reported
Owners of the 2006 Audi A4 report fuel pump failure at a median of 90,000 miles. A quarter of the reports come in before 45,000 miles and a quarter after 110,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 140,000 miles at the ninetieth, a spread of 128,000 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
27% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 12,000 miles | 44,135 miles | 90,438 miles | 110,000 miles | 140,000 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $600–$2,600 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 11 model years of this car. It shows up earliest on the 2009, at a median of 55,000 miles, and latest on the 1999 at 145,000 miles.
By volume the 2004 carries the most reports, with 48; the 2006 has 12. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

Took the audi a4 quattro to the audi connection of cincinnati dealership for a check engine light (cel) on p codes p2293 & p0089 which indicates a possible cam follower, cam shaft, and/or high pressure fuel pump (hpfp) issues back on thursday morning april 10th, 2014. Later, I spoke with lee at the service desk who stated that the cam shaft was worn and would be a covered item on this internal audi campaign; however, he would not be able to get to it until the next business day since it would take a full day to repair pushing it into friday.I received a call friday april 11th at approximately 11:30 a.m. And it was lee stating that the cam shaft would not be replaced due to an oil pressure issue that damaged both cam shafts and engine. He later stated that the engine would have to be replaced that could cost upwards of $8,000.00. I later suspected oil sludge issues that were also on a recall. Yes, the audi connection did later relent, after stating earlier that they would not perform the work, offering to perform the repairs at a later timeline; a timeline that I could not afford to be without a vehicle and paying on a rental.

How far this goes
Complaints are voluntary, so 12 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does fuel pump failure happen on the 2006 Audi A4?
Across 11 owner reports that included an odometer reading, half were filed by 90,000 miles. A quarter were filed before 45,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel pump failure on the 2006 Audi A4?
12 reports have been filed with NHTSA, about 0.7 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
