The Discovery Sport Si4 was the petrol variant in the pre-2019 Discovery Sport range, alongside the diesel eD4 and TD4 models. It uses the Ford EcoBoost 2.0-litre four-cylinder petrol engine — a turbocharged unit shared across several Ford and Volvo models of the same era, as well as other Land Rover applications. The Si4 badge distinguished it from the diesel options in the range, and it was available throughout the L550 generation from its 2015 launch until the 2019 facelift, when the diesel-focused Si4 was discontinued and petrol variants were rebadged under the P-series naming convention. The Discovery Sport Si4 is no longer in production, but we continue to rebuild and replace engines for every one still on the road. Land Rover Discovery Sport Si4 Engine Compatibility Before we quote or supply anything, we confirm: Your Discovery Sport is the Si4 petrol variant (not a diesel eD4/TD4) Your engine code (Ford EcoBoost 2.0L) Your generation (L550, pre-2019) Drivetrain and ancillary specification Any electronics or ECU considerations specific to your exact build This is why we always start with your registration rather than a generic Discovery Sport quote — it protects you from paying for parts that don't fit your actual car.

Do you rebuild Ford EcoBoost Discovery Sport Si4 engines? Yes. We replace timing chains, bearings and gaskets as standard on every Discovery Sport Si4 rebuild.

Yes — nationwide recovery is available from £70, and most vehicles are collected within a few hours of booking. How long does a Discovery Sport Si4 engine rebuild take?
