My New Audi A6 Broke Down at Just 280 Km and Needed a New Differential
In my brand-new Audi New A6 Sedan TDI Quattro, which I purchased from the Doğuş Oto Esenyurt dealership on 12/05/2025 and took delivery of on 12/06/2025, "Drive Fault" and "Vehicle Network Fault" warnings appeared the very next day after delivery, with the vehicle at only 280 km.
Following the authorized service center's guidance, I waited for the part, and when the vehicle reached 10,000 km, the differential was replaced. Having a differential replacement on a brand-new, premium-segment vehicle from the very first day is already unacceptable, but my grievance didn't end there.
On 06/04/2026, when the vehicle had only 18,000 km, the same system group failed again; the screen once again displayed "Drive Fault," "Vehicle Network Fault," and "Driving Dynamics System Faulty" warnings. The fact that the same fault recurred despite the differential already having been replaced for the initial fault clearly shows that the vehicle is defective and carries a chronic manufacturing/system flaw.
I had also come from out of town, and I was left without a replacement vehicle!
Since my vehicle was no longer safe to drive, I had it towed from Mardin, where I reside, to Doğuş Oto Esenyurt's service center on 06/09/2026 via a tow truck. Even though I stated that I urgently needed the vehicle for my business activities and daily life, and that I had come from Mardin to Istanbul specifically for this process, I was told a replacement vehicle could only be provided 3 days later (06/12/2026). I've been left stranded in Istanbul for days.
In summary:
A severe fault occurring at only 280 km on the very first day of a 6-month-old vehicle, leading to a differential replacement,
The same severe faults recurring a short time later, requiring the vehicle to be towed to service again,
Despite this hardship, being made to wait days for a replacement vehicle, disrupting both my work and personal life,
This is entirely contrary to the quality, safety, and customer satisfaction standards expected from the Audi brand.
I am urgently requesting the following from Audi Turkey and Doğuş Oto officials:
That my vehicle be replaced with a new (brand-new) one due to the chronic and severe faults experienced,
That an appropriate replacement vehicle for my segment be provided immediately until this process is completed,
That I receive an urgent, written response regarding this process.
I expect a solution befitting the brand's name, focused on customer satisfaction, and permanent. Otherwise, I want to state that I will pursue my legal rights to the fullest extent.
