Known issues and risks
Listed from most frequently reported, each with its source.
Oil dilution: diesel mixing with engine oil
Often reported
Users report oil dilution (diesel mixing with engine oil) due to DPF regeneration issues. This exceeds the allowable fuel content in oil, requiring early oil changes and increasing component wear.
Engine Internal
FAP/DPF clogging and frequent regenerations
Often reported
Many owners of the 2.0 TDI versions used in the A3 8V report issues with the particulate filter (FAP/DPF): more frequent regenerations than expected and failed regenerations.
Exhaust Emissions
Clogged EGR valve and performance loss
Often reported
In TDI engines, the EGR valve can become clogged with soot over time, causing power loss, rough running, increased emissions, and frequent DPF regenerations.
When buying a 2016 model 2.0 TDI, check service history, test drive, and look for engine/transmission warnings. Most commonly reported issues: oil dilution: diesel mixing with engine oil; FAP/DPF clogging and frequent regenerations; clogged EGR valve and performance loss.
