Lot 410: 2016 Audi S6 Prestige

Based on my research, here are the most common reliability issues with the 2016 Audi S6:

Major Issues:

1. Turbocharger Oil Strainer Clogging - This is the biggest issue. Audi issued a major recall (22V178000) for 2013-2017 S6 models because the turbocharger oil supply strainer can become blocked, causing turbo bearing failure. This can lead to complete turbo failure costing $8,000-$12,000+ to repair. The recall addresses this issue, but if not done, it’s critical to have it checked.

2. Mechatronic Unit Failures - The 7-speed S-Tronic dual-clutch transmission’s mechatronic unit is prone to failure, especially the cooling and pressure solenoids that start sticking around 80,000-100,000 miles. Repair costs are typically $5,000-$7,000.

3. Timing Chain Tensioner Issues - The timing chain tensioners can fail between 80,000-120,000 miles, potentially causing catastrophic engine damage if the chain skips.

Moderate Issues:

1. Carbon Build-up - Direct injection causes carbon build-up on intake valves, requiring cleaning every 60,000-80,000 miles.

2. Electrical Gremlins - Various electrical issues including MMI system problems, sensor failures, and wiring issues.

3. Oil and Coolant Leaks - Various seal and gasket failures leading to leaks.

Maintenance Costs:

• Annual maintenance averages $1,000-$1,500
• Major services (60k, 80k, 100k miles) can be $2,000-$4,000 each
• Turbo failure repair: $8,000-$12,000
• Transmission mechatronic: $5,000-$7,000

The Good News:

• The 2016 model year is actually considered more reliable than 2013-2015 models
• Many issues have been addressed through recalls and updated parts
• When properly maintained, these cars can be reliable daily drivers

Recommendation: If you’re considering this 2016 S6, make sure the turbo oil strainer recall has been completed and get a pre-purchase inspection focusing on the transmission operation and any signs of turbo issues. The car you’re looking at appears well-maintained with 24 service records, which is a good sign.
