This 2013 Audi A3 2.0 in to a local car dealership before coming where they had tried service regenerations and in tank treatments, none of which had worked.
We carried out the pre-clean checks and found 3 faults that would cause the DPF to block.
A blocked DPF is usually a symptom, not the cause.
After rectifying the cause of the blocked DPF we carried out The DPF Doctor 3 stage clean.
