Discovery Sport exhaust
Exhaust and emissions parts for Land Rover diesels and petrols, including DPF and EGR components.
What is specific to the Discovery Sport
Exhaust and emissions parts on the Discovery Sport depend on the engine: the diesels (2.2 TD4 turbodiesel, 2.2 SD4 turbodiesel and D180 2.0 turbodiesel) use emissions hardware that the petrol engines (2.0 Si4 turbo petrol and 2.0 turbo petrol, 183kW) do not, and manifolds, pipes and sensors differ between them.
Have this ready when you enquire
- The 17-character VIN from your licence document, which identifies your exact L550 (sold here 2015–present) and its build.
- The engine code or number, because this model was sold with the 2.2 TD4 turbodiesel, 2.2 SD4 turbodiesel, 2.0 Si4 turbo petrol, D180 2.0 turbodiesel (Ingenium) and 2.0 turbo petrol, 183kW (Ingenium).
- A photo of the old part or its part number, if you can get to it.
Known Discovery Sport exhaust faults
DPF and EGR valve problems
Town driving prevents DPF regeneration, leading to blocked filters, and EGR valves on the diesels are a regular replacement item.
Parts commonly needed for the Discovery Sport
For the Discovery Sport, engine and emissions parts lead: timing chain kits for the 2.0 diesel, timing belt kits for the 2.2, turbochargers, EGR valves, DPFs and NOx sensors.
Discovery Sport exhaust questions
Why is my Land Rover exhaust blowing?
The usual causes are a failed gasket at the manifold or downpipe, a split flexi joint, a rusted pipe or silencer, or a loose clamp. A workshop can find the leak quickly with the vehicle on a lift.
Can I replace only part of the exhaust?
Yes. Land Rover exhausts are made in sections, so you can replace just the damaged section. Fit new gaskets, clamps and rubber mounts at the joints you disturb.
