What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 773 complaints with NHTSA about the 2006–2008 Audi A4, and 426 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 38,000 and 88,000 miles. The median is 63,241 miles.
The most-reported areas are the airbag system (39.8% of complaints, typically around 82,000 miles), the exterior lighting (23.3% of complaints, typically around 58,000 miles), the engine (5.8% of complaints, typically around 84,000 miles).
4 recall campaigns cover this generation.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 63,241 miles; the figures below show which parts of the car run ahead of that and which run behind.
The airbag system accounts for 39.8% of complaints (308 reports, 54 of them with a mileage figure), with a median of 82,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 62,000 and 112,000 miles.
A single system taking 39.8% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The exterior lighting accounts for 23.3% of complaints (180 reports, 147 of them with a mileage figure), with a median of 58,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 42,000 and 77,500 miles.
The engine accounts for 5.8% of complaints (45 reports, 35 of them with a mileage figure), with a median of 84,300 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 61,000 and 95,000 miles.
The electrical system accounts for 5.2% of complaints (40 reports, 31 of them with a mileage figure), with a median of 68,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 38,100 and 89,000 miles.
The transmission and driveline accounts for 4.8% of complaints (37 reports, 34 of them with a mileage figure), with a median of 66,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 43,000 and 96,000 miles.
The engine and its cooling system accounts for 3.0% of complaints (23 reports, 19 of them with a mileage figure), and it fails early — a median of 35,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 9,000 and 72,300 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2006 model year drew the most — 343 complaints — while 2008 drew the fewest at 204. The median year sits at 226.
Recalls and what they cover
NHTSA records 4 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
The campaigns cluster around the airbag system (4). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
Of the 773 complaints filed against this generation, 25 reported a crash; 6 reported a fire; 16 reported an injury. Crash-involved reports represent 3.2% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 38,000 and 88,000 miles, with a median of 63,241. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the airbag system and the exterior lighting are where this generation's reports concentrate, so those are the areas worth a specific look. The exterior lighting in particular shows a median failure mileage of 58,000, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
Documented problems
Engine — High Pressure Fuel Pump Cam Follower 2006–2008 (2.0T FSI only)
The bucket-style cam follower that rides between the intake camshaft lobe and the mechanical high pressure fuel pump wears through and can be punctured, after which the pump plunger contacts and destroys the camshaft lobe, and metal debris enters the oil. Symptoms are power loss, rough running and a check-engine light. The follower is a wear item that owners must inspect periodically; the defining B7 2.0T FSI failure.
Engine — Timing Chain Tensioner 2006–2008
Hydraulic timing chain tensioner wear on the FSI engines, permitting chain slack and, in the worst case, timing jump.
Engine — Intake Valve Carbon Deposits 2006–2008 (FSI engines)
Direct injection means no fuel washes the intake valves, so carbon accumulates and causes misfires, rough idle and power loss; requires periodic walnut-blasting.

What owners reported
No failure, accidents or injuries. The problem is a lag in acceleration at throttle tip in. The lag can cause dangerous situations when pulling in front of traffic and the car fails to accelerate in a timely manner. It has caused us to become hesitant when driving the vehicle and we lack confidence when pulling…

Right and left dipped headlight warnings appear frequently since the year i purchased this car. The headlight flickers/pulses, then goes out and the warning appears. Turning lights to the off position and back on generally brings both headlights back on but the same headlight or other side will often fail moments…

This problem has occurred many times since i have owned the car with increasing frequency. Now the issue is happening every time i drive the car. The issue is that when my lights are on, they will flicker and go out. I will get an error message that says "dipped headlight". The only solution to this problem is to flip…

I have the a4 w/ 3.1 Liter v6. Almost immediately after purchase, transmission exhibited bumpy lurching start from stop. Audi diagnose said that's symptomatic of this transmission and engine combination. Nothing could be done to prevent. Within 1st year, the car would stall and completely shut down, necessitating…
