Used Audi Exhaust & Emissions Parts

The exhaust and emissions system plays a critical role in your Audi's performance, emissions compliance, and engine sound. From the catalytic converter to the rear muffler, each component must function correctly for smooth operation and UK road-legal status. Used Audi exhaust parts from our breaker network offer substantial savings — particularly on expensive items like catalytic converters and DPF filters.

DPF (diesel particulate filter) units for the 2.0 TDI and 3.0 TDI are among the highest-value exhaust components sourced through our platform. New DPF units from Audi dealers can cost over £1,200. Our vetted breakers supply used units checked for blockage and physical condition at a fraction of that price. AdBlue SCR (selective catalytic reduction) systems fitted to EU6-compliant TDI engines are increasingly available as older EU6 vehicles enter the breaker pool.

Exhaust manifolds — particularly the cast-iron units on the 2.0 TDI B8 A4 which are prone to cracking at the EGR port — are consistently requested items. Lambda (oxygen) sensors for upstream and downstream positions across all TFSI and TDI engines are stocked by the majority of Audi specialist breakers in our network.
