No-start or intermittent start failure on the 2005 Audi A6
Only 3 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When no-start or intermittent start failure gets reported
There are 3 reports of no-start or intermittent start failure on the 2005 Audi A6, 3 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 88,000 miles. It is the 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 105,000 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 $200–$1,800 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 5 model years of this car. It shows up earliest on the 2016, at a median of 40,000 miles, and latest on the 2012 at 165,000 miles.
By volume the 2006 carries the most reports, with 7; the 2005 has 3. 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.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
On 1/25/2007 car was cold in garage. Would not start on first or second attempts. On third attempt the car turned over but the epc light illuminated and the entire vehicle was heavily shaking and rocking back and forth. No power to drive the vehicle. Had it towed to the dealership (schaumburg audi). Dealer said the computer recorded multiple cylinder misfires but that there was nothing else they could find wrong. Car was kept overnight and returned to me when no further problems could be found and the event could not be replicated. Nothing was actually repaired and no parts replaced. *jb
I have a 2005 audi a6 I drove the car for 2 weeks went out to start the car and it would not start the wheel was locked gear shifter locked. I had the car towed to audi of south burlington. I told them I believed it was a issue with the access start control unit as I had read it many times over from others who had experienced the same issue. They told me it was the ignition switch replaced it to the tune of $881.00 and sent me on my way. Luckily enough I was not stuck with a no starting car in an emergency or unsafe situation. 3 weeks to the day same issue. Back at the dealer guess what it's the access start control unit. When is someone going to hold audi accountable for this common problem? This could pose a serious safety issue for the consumer stuck with a completely non functioning car because it happens just like a light switch with no warning!! Let me illustrate this for you... You're out in a snow storm, you have your children with you, you have no cell service.... Ok you pull over or shut your car off for any reason, although it has been starting back up this time it doesn't. This isn't a safety issue when they find your…

How far this goes
This page is kept out of search results because 3 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 3 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 no-start or intermittent start failure happen on the 2005 Audi A6?
Across 3 owner reports that included an odometer reading, half were filed by 105,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is no-start or intermittent start failure on the 2005 Audi A6?
3 reports have been filed with NHTSA, about 0.2 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.
