"warning: Gearbox malfunction- you can continue driving" appears after about 15 minutes of driving. The car does not malfunction, changes gears without problems, and warning remains on screen. Car has 58K miles and has been well maintained. Took to Audi dealership and advised module G676 is bad. Cost to repair: $5334.39. There is a tsb for this warning on this issue for several years of Audi. Audi will not cover any of the costs to repair although they realize this is a common failure among this vehicle. This is a manufacturer issue!! why are they not being held accountable?

Mechatronic failure. Car was fully serviced and maintained by Audi however Audi will not pay for cost of replacement. Cost of replacement is $3,000 usd. Car displayed gearbox malfunction limited driving ability, parking brake failure then lost all drive and car was stuck in N. I was unable to shift out of gear and put the car in park this is a safety issue.

Hard clunk when selecting gears from P to R to D. when coming to a stop in traffic the car lurches forward like being rear ended. Sometimes after a complete stop has been made the car will surge forward a considerable amount which may possibly cause me to hit the car in front of me.

At 57K miles got trans overheating warning while driving on back roads and car started to loose power. After a few secs went away. On way home same thing happened and was able to limp to dealer. Dealer diagnosed w/ bad mechatronics unit which appears to be common problem w/ early B8 dsg transmissions.

Hard clunk when selecting gears from P to R to D. when coming to a stop the car lurches forward almost like being rear ended. Sometimes after a complete stop has been made the car will buck forward slightly

Mechatronics issue. Car will surge in stop and go traffic when operating at colder engine temperatures. Common issue amongst the 2010-2012 models.

Jerky dsg transmission shifts, whether downshifting or up shift. Going slow or fast, this only happens once trans is up to temp, I'm pretty sure my mechatronics unit is failing.

The S-tronic/dsg transmission is having issues downshifting. It will rev up high when coming to a stop as well. There is also a harsh clunk when shifting from neutral-drive-park. Audi recommended replacing the mechatronics unit in the transmission. The mechatronics circuit board has already been replaced at owners cost and now they want me to replace the entire mechatronic unit at my cost ($3800+). this is a common issue with these cars and there needs to be a recall for these transmissions. It is known that these transmissions are faulty and Audi does not want to take responsibility for these issues.

At approx 55K miles, mechatronics unit failed. Extremely rough shifts from 1-2 and 2-1, lurching forward after coming to complete stop. Dealership replaced mecharonics unit. At 74K miles entire dsg gearbox failed, while on highway with virtually no power or ability to accelerate. Luckily traffic was at near stop due to rush hour, was able to make it to next offramp in what they call 'limp mode'. dealership is replacing entire transmission.

Symptomatic dsg engagement issues. Braking down to 0 mph from gears above 1st will hold the gear until the last second before total stop where it feels the car is rear ended and loud bang in the transmission. Moving from reverse to drive and back can sometimes cause loud bang in transmission. Upshifting from 1st to 2nd sometimes has trouble getting into gear

I have just recently purchased this car from an older man who was very kind to the car. I have had this vehicle for the whole two months when I entered my garage to leave for the day I received a"gear box malfunction, you may continue driving: Limited functionality code" I have done my hours of research and have found out this is a simply a problem lot of people are having. This is something Audi is selling on their cars knowing these have issues!!!!! I want to take further action, Audi should step up and repair all the broken units they have been selling. These units have given 95 percent of Audi owners problems. Really makes me feel like I'll never buy another.

I was driving and came up to stop light. Car flashed up warning saying gearbox malfunction limited functionality. Car would not change up or down smoothly or quickly. Loss of power on every shift for over a second. Had Audi of stevens creek change dsg fluid a couple of week prior.

The dsg transmission is very jerky in 1-2 gears it operates as though the clutch is not engaging/disengaging properly. When traveling at highway speeds with the cruise control engaged the engine rpms wander as though the clutch is engaging and disengaging. Starting from a deadstop or driving at low speeds are very uncomfortable due to the jerky-ness.

While driving in rush hour bumper to bumper traffic the 2010 Audi S4 with the dsg S-tronic transmission becomes very jerky, causing it to surge when starting and stopping or driving at low speeds. As a result it is hard to control, especially in tight traffic, parking areas, or around pedestrians. Additionally, when coming to a complete stop when in this condition the shift from 2nd gear to first happen in such a way the it give the feeling that the car has been rear ended.

I was driving on a normal stretch of flat highway approximately 65mph and the dash lit up like a christmas tree out of the blue. Car indicated reverse gear not available, transmission warning lights, and tire pressure monitor system problem all at the same time. Car went in to a "limp mode" and it only shifted in even number gears, and felt like the car was dangerously unstable due to erratic missed shifting. The car had recently been in prior for a service check and had no codes or check engine light problems at all! after a little research it is a well documented problem that the mechatronics fails on this vehicle rather often. That was the problem. Cost of repair was near 3300$. I was approximately 4K miles out of warranty when this occurred, after numerous persistent exchanges with Audi of America they finally decided to cover the failure as I was considering seeking legal action. ( I had the part in hand and could submit it to failure analysis engineering for cause). On an poll on a popular Audi website, approximately 15% of these mechatronics have failed. The design issue is a circuit card embedded in hot transmission fluid that affects the hydraulic control of the transmission. If the transmission is damaged it can be over a +10K$ repair.

Dsg transmission (auto) is jerky. Does not engage smoothly and is very erratic. Can slam into the next gear.

Pulled out of parking lot and received a gearbox malfunction warning along with a TPMS malfunction. Warning on dash indicated that I could continue driving. I drove vehicle for approximately another mile and while going thru a roundabout, the car shut off. I was able to pull over to the side of the road and get the vehicle started again. I continued the rest of the way home for about 2 more miles. The mechatronic unit was determined to be faulty and was replaced.

Mechatronics unit failure in dsg transmission. Hard shifts from 1st to 2nd and 2nd to 1st while stopping. (vehicle makes loud drivetrain bang noise, shakes and stops abruptly when slowing down and trying to come to a stop, almost as if you slowed down to 5-10mph and then slammed on the brakes.)

- Savannah, GA, USA

Mechatronics unit failed in the vehicle automatic transmission. Transmission failure message listed on car dashboard. Car would not shift out of 1st gear and there was no reverse gear. Car had to be towed to the dealership for repair. Multiple web forum posts stated the Audi B8 models suffered this failure frequently.
