Vauxhall Signum Catalytic Converter (2003-2008)

A catalytic converter is an essential automotive component designed to reduce harmful emissions from the engine exhaust gases. For the Vauxhall Signum, it helps convert toxic pollutants into less harmful substances before they exit the exhaust system, ensuring compliance with environmental regulations and improving air quality.

The Vauxhall Signum catalytic converters vary according to engine type and code:

• Diesel engines such as 1.9 CDTI (Z19DT), 2.0 TD DTI (Y20DTH), and 3.0 V6 CDTI (Y30DT)
• Petrol engines including 1.8 16V (Z18XE) and 3.2 V6 (Z32SE)
• Some models include DPF versions (diesel particulate filters) integrated with catalytic converters

Always verify the engine code and VIN for exact compatibility.

The specifications vary by model, including power, engine code, and position in the exhaust system:

• For example, 2.0 TD DTI engine uses reference BM80211H with a stainless steel construction, approx. 1200 mm length and 3.5 kg weight.
• 3.2 V6 petrol models have references like 13103940 / 13103942 with Euro 4 homologation
• Diesel units may include DPF catalytic converters like reference AS84046D for 1.9 TD CDTI DPF versions

These converters often come with mounting kits and warranties up to 3 years.
