What owners report
Owners of the 2008 Audi A4 report two dominant themes: a large wave of Takata passenger-front airbag recall notices, often with parts unavailable for long stretches, and engine complaints — chiefly excessive oil consumption and premature camshaft / high-pressure fuel pump wear. Other recurring reports include transmission shuddering at low-speed downshifts, exterior lighting faults (headlights dropping out), stuck or surging accelerator pedals, and early tire sidewall failures.
- Air bags
Passenger airbag recall with no remedy available
- 108 complaints (62%)
- median 88,000 mi at 9.5 yrs old (25 state mileage)
- 5 mention a crash, fire or injury
- filed 2016–2026
Owners describe receiving Takata passenger-front airbag recall notices and then being unable to get the repair done, with dealers reporting that the correct kit or part is not in stock and no timetable given. Some complaints describe driving with the passenger seat unoccupied as advised in the notice, or an airbag warning light on. Several owners also report airbags not deploying in a collision, which they connect to the open recall. Filed from 2016 through 2019, mostly on vehicles with 40,000 to 125,000 miles.

What to check: Ask for documentation that the passenger-front airbag recall campaigns were completed, and have a dealer run the VIN to confirm no open campaigns. An airbag warning light should be diagnosed before purchase.
2 excerpts from owner complaints in NHTSA records
“Takata recall. I received a notice in march of 2017 of a recall on my vehicle for the takata passenger frontal airbag. Ten months later, repair is not available nor have I been notified when parts will become available. This has caused undue hardship. My dealer has offered no compensation in the form of a loaner or other assistance.”
NHTSA complaint #11052495, filed 2017-12, 63,000 miles“Takata recall my complain is the lack of importance by Audi and takata when they dont have a time table as to when parts are going to become available to fix this problem and they dont care if you have to sit your spouse or children and potentially expose them to a tragedy, should you be involved in a auto accident. In my case I have 2 vehicles, different manufacturers and both of them have the same recall for the air bags.”
NHTSA complaint #10906042, filed 2016-09, 112,000 miles - Exterior lighting
Headlights dropping out (dipped headlight warning)
- 10 complaints (6%)
- median 73,500 mi at 8.0 yrs old (8 state mileage, few)
- filed 2012–2019
Owners report a "dipped headlight" message on the dash followed by one headlight flickering or going out while driving at night, sometimes coming back after restarting the car and later failing completely. Complaints mention adaptive/dynamic headlight range faults and describe difficulty getting the issue resolved, with some noting the bulb is hard to reach. Reported from about 12,000 to 123,000 miles, in several cases on vehicles over five years old.
What to check: Test all headlight functions, including high beam and range control, and look for a dipped-headlight warning. Ask whether bulbs, ballasts or the headlight unit have been replaced.
2 excerpts from owner complaints in NHTSA records
“Headlights shut off while driving at night. I have looked at many forums and have seen this a problem in over 70 percent of Audi A4 b7 owners. This is an extreme hazard and needs to be fixed. My headlights shut off while driving at 8 pm. They would flicker, but would not re fire. I am speaking about the bi-xenon headlights for the 2006 - 2008 Audi line. I ended up driving home with my fog lights on.”
NHTSA complaint #10478060, filed 2012-10, 68,000 miles“I have the dipped headlight problem in my 2009 Audi A4/b7 driver-side headlight. I have my lights set to always be on. Every now and then I'll see the light flicker or go out and get the dipped headlight warning. What I do is turn my lights fully off, leave them off for a few seconds, and then switch them back on. This seems to fix the problem. Until now the headlight completely goes out with only the (dipped headlight) warning on my dashboard. …”
NHTSA complaint #10505484, filed 2013-04, 69,000 miles - Engine
Excessive oil consumption on 2.0T engine
- 11 complaints (6%)
- median 48,000 mi at 4.6 yrs old (8 state mileage, few)
- filed 2009–2024
Owners describe adding roughly a quart of oil every 1,000 to 3,000 miles, with the oil light coming on despite oil being present, and say dealers initially called the usage normal before later attributing it to bad seals or piston rings. Some complaints mention the engine being taken apart or rings replaced to address consumption. Widely reported from around 19,000 to 105,000 miles, usually noticed within the first few thousand miles of ownership.
What to check: Check the oil level and dipstick condition, ask how often oil is added between changes, and look for records of any consumption-related engine work. Follow the oil level between services.
2 excerpts from owner complaints in NHTSA records
“I have had repeated issues with oil consumption. Oil overconsumption has been the subject of a class action lawsuit for 2009-2011 a4s. For some reason the 2008 was not included in the lawsuit. I have had to top my oil off every 3,000 miles, at a minimum, for the entire life of the vehicle. This has been a safety issue numerous times where I was not close to any facility that sold oil and was forced to drive the car on low oil a long distance in order to top it off. …”
NHTSA complaint #10786163, filed 2015-10, 105,000 miles“I recently purchased a 2008 Audi A4 2.0 with approximately 37,000 miles on it. I've driven the car less than 3000 miles and had to add 1 quart of oil every month of ownership (3). Audi dealership says this is normal. Like the previous complaint listed on this topic, I too have see a number of blogs on the subject of the 2008 A4's having issues with excessive oil consumption. I've also seen mention of a technical service bulletin being issued by Audi on this but I've yet to find it.”
NHTSA complaint #10424608, filed 2011-09, 37,000 miles - Vehicle speed control
Stuck or surging accelerator pedal
Mentioned in 6 of 60 sampled complaints
Complaints describe the gas pedal sticking open or the car continuing to accelerate after the driver lifts off, requiring braking, shifting to neutral or shutting off the ignition. In other cases owners report a lag followed by a sudden surge when accelerating. Some complaints were tied to a fuel pressure regulator or throttle issue diagnosed by a dealer. Mostly reported between about 11,000 and 64,000 miles, across a range of model years in the sample.
What to check: During a test drive, check that the pedal returns smoothly and that acceleration is progressive from a stop and at highway speed. Ask whether the throttle body or pedal assembly has been serviced.
2 excerpts from owner complaints in NHTSA records
“I was driving on a parkway and moved into the left lane to pass and when I accelerated, the gas pedal stuck and would not release. The car continued to accelerate -- I braked to slow down however, the gas pedal was still stuck. After tapping on the gas pedal for about 10 seconds, it finally released.”
NHTSA complaint #10494695, filed 2013-01, 52,000 miles“After reaching an appropriate speed on a highway, I eased off the gas pedal but the car continued to accelerate. I removed my foot from the gas pedal entirely but the pedal stayed down. I shifted the car into neutral, turned on my hazards and pulled over to the breakdown lane. I got out of my car and checked the still depressed pedal to see if anything was obstructing it and there was nothing. I pulled the pedal up and the engine stopped revving.”
NHTSA complaint #10483293, filed 2012-11, 29,911 miles - Engine
Camshaft and high-pressure fuel pump wear
- 8 complaints (5%)
- median 70,750 mi at 7.3 yrs old (6 state mileage, few)
- filed 2012–2022
Complaints describe premature wear of the camshaft lobe and cam follower, sometimes with a P0087 code, causing rough running, surging, hesitation and loss of power. Owners report the follower or pump being replaced without the camshaft, and repeat repairs at similar mileage; several note a warranty extension applied to earlier model years but not to the 2008. Typically reported around 60,000 to 85,000 miles, with some repeat repairs about 13,000 miles after the first.
What to check: Ask whether the cam follower and high-pressure fuel pump have been inspected or replaced, and request service records showing camshaft work. A pre-purchase scan for fuel pressure codes is worthwhile.
2 excerpts from owner complaints in NHTSA records
“Problem with my vehicle is the high pressure fuel pump and camshaft. Apparently there has been a warranty for 2007 and older models and I was also told by a dealer that 2009 and new models were covered. The warranty was an extended to 10 years/120,000 miles for this issue. I called corporate also to see if there may have been a mistake at the dealer that my vehicle was not covered and they said it was not mistake. …”
NHTSA complaint #10736172, filed 2015-07, 95,550 miles“Problem: premature wear of the cam and cam follower resulting in p0087 errors. This causes the car to run very erratic, surging and bucking and a general loss of power. There is an Audi TSB (technical service bulletin) on this very issue for my 2005, 2006 and 2007. This is a very wide spread problem! My 2008 Audi should be covered. --- at around 60k miles the car started experiencing the dreaded premature wear of the cam lobe follower and the high pressure fuel pump lobe. The follower was replaced but the cam was not. …”
NHTSA complaint #10462685, filed 2012-06, 61,087 miles
Buying note. Check the VIN for open airbag recalls and confirm any completed remedy in writing, then verify oil consumption and camshaft/fuel pump service history on the 2.0T. A careful test drive for transmission shudder and headlight faults rounds out the picture.
Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample. The excerpts come from NHTSA's public complaint records and are unverified; capitalisation is normalised, NHTSA staff notes are removed, and shortened text ends with “…”. Something wrong? Request a correction.
NHTSA recorded 175 consumer complaints for the 2008 Audi A4. 72 of the complaints include a mileage, and 38% of those were filed for vehicles with under 50,000 miles; the median is 62,000 miles. Of all complaints, 8 involved a crash, 1 a fire, 4 an injury, according to the filers. NHTSA lists 4 recall campaigns and 451 technical service bulletins for this model year. Compared with the other 6 Audi A4 model years that have at least 25 complaints and are old enough to compare, this one scores 100 out of 100, where 50 is a typical year for the model (more complaints than typical for this model). The comparison allows for the era and for how long each year has had to collect complaints, but not for how many vehicles were sold.

Example complaints
Air bags: “No air bags available after 2 years. Now I am told that there no new bags and the 1st recall bags are no longer available. This after I received numerous notices to get it fixed! At no time was I assisted by my dealer ship north shore Audi, in brown deer, wi. I find this unacceptable and unethical! Please help me. When I called Audi corp. They were even less helpful than the dealership. This after wanting on hold for over 30 minutes!”
NHTSA complaint #11035726, filed 2017-10, 65,000 milesEngine: “I too am having issues with my Audi A4 turbo I have to put oil in my vehicle seems like every month or so. I've had the car for only 6 months and I have had 2 oil changes and about 10 quarts of oil in that time. My mechanic says with synthetic oil you should only need oil changes twice a year. I too keep getting told this is normal...this is not normal, there should be something done about this situation....this can not be good for my engine. …”
NHTSA complaint #10595440, filed 2014-06, 59,000 milesTransmission and drivetrain: “It happens when I turn the car on and I go to park it. When I pass reverse. It seems to happen a lot more often after it rains. My transmission is going into limp mode due to a major fault. Code p0706: transmission range sensor circuit range/performance the transmission range sensor tells the TCM the position of the gear lever. It also contains a neutral safety switch, which ensures that you can only start your car in neutral or park. …”
NHTSA complaint #10993863, filed 2017-06, 11,000 milesExterior lighting: “My car gave me this message left headlight main beam dipped and the left headlight went off. The left head light come on for a while when I start the car in the night for a while and then goes off when I am on the road. I checked with the Audi USA customer service line and they didn't give me any plausible explanation. I went online with my car problem and found out that many Audi 2005-2009 have the same problem and the Audi dealerships don't want to deal with this issue with their cars”
