If you are thinking about purchasing one of these models from those years, this list will help guide you:

Audi A4 Oil Consumption

Oil levels have been known to drop significantly in some Audi A4s, particularly the 2l Turbo versions manufactured in 2007, after just 2500 miles of driving and would require refilling using around 1/2 gallon. If the level indicator illuminates, balance can be restored with just a quart of 5w-40 oil.

In certain cases, it may be necessary to add up to one quart of oil every five-thousand-eight hundred miles due to extreme oil consumption that results from inherent design flaws within the engine.

Unfortunately, there have been reports of failure in the oil rings that cause engines to overheat and, eventually, valves to break down.

Audi A4 Airbags Problems

The National Highway Traffic Safety Administration defined a recall (Campaign Number 21V874000) that affected roughly 208,332 Audi A4s in the years of production from 2017 to 2022 but is most noticeable between 2007 and 2011.

There are different types of airbag-related troubles ranging from airbag warning lights turning on, mostly due to corroded wires, to a more grave situation where airbags fail to deploy. The root cause of this problem is the oxidation (rusting) within the Passenger Occupant Detection System connection cable, leading to wrong diagnoses by the airbag system.

Audi A4 Speed Control Issues

Owners of Audi A4s between those model years reported experiencing an astonishing number of 99 cases involving speed control issues. Another common problem is unintentional acceleration, which is dangerous for drivers’ lives as cars go on without control.

Imagine a driver resting one foot on the brake pedal and another on the accelerator. While keeping pedal pressure on a brake-capable car, he decided to depress an accelerator after securing a suitable gap in traffic. Ideally, this would result in a sharp right turn into the next lane. In contrast, with these affected vehicles, the story becomes different. The car changed lanes, completely crossing from one side to another, while its driver had no control whatsoever over it towards moving traffic.

In some cases where drivers are powerless, cars have gone into reverse gear when they should be going forward, leading to lethal conditions. Additionally, vehicles have been known to accelerate inside parking garages, causing accidents inexplicably.

Audi A4 Engine Cooling And Powertrain

Enter into difficulties facing those with Audi A4 models manufactured in 2011, and you will see many problems involved. Commencing with power train issues, clutch failures emerge as a recurring theme, coming up at around mileages of about four thousand five hundred miles, followed by another high-occurring rate within twenty-eight thousand and thirty-one thousand miles.

Eventually, clutch slippage results in catastrophic “molten” conditions of the clutch, and, finally, this bearing fuses to the transmission shaft. In addition, abrupt engine seizures have been reported while driving at high speeds on highways.

The 2011 Audi A4 2.0 has been strongly accused of extensive oil consumption resulting in engine catastrophes, especially those beyond 25000-36000 miles. This oil consumption problem has led to many complaints because it can make an engine break down at high speeds. A much worse version involves a fire that starts from the front section of the A4. It is an acrid smell emanating from the air conditioning system that forebodes about the engine malfunctions, eventually causing such dangerous circumstances.
