AUDI A6 TDI DIESEL PROBLEMS EDMONTON (EGR FAILURE)
The Audi A6 TDI (2.0L diesel) from 2012 to 2018 has several common issues, with EGR valve failure and diesel particulate filter (DPF)
clogging being the most frequent. Edmonton’s cold winters and stop-and-go city driving are particularly hard on diesel emissions systems. Auto Imports services Audi TDI diesel vehicles in Edmonton.

- EGR valve clogs with carbon deposits — common 80,000-120,000 km
- Symptoms: rough idle, black smoke, power loss, check engine light
- Fault codes: P0400-P0404 EGR flow malfunction

$2,000-$4,000 DPF replacement
