BMW X2 sDrive18i Engine Supply and Fit for Bexley and South East London

If your BMW X2 sDrive18i engine is losing coolant, misfiring or has failed completely, our team can repair it, or supply and fit a reconditioned or used B38. We work with X2 owners across Bexley and South East London.

The 1.5 Three-Cylinder B38 Petrol Engine Behind the X2 18i

The X2 sDrive18i (F39) uses BMW's B38A15A, a 1.5-litre three-cylinder TwinPower Turbo petrol engine. Depending on the version, it produces 136–140hp (100–103kW). It drives the front wheels through either a 7-speed Steptronic DCT or a 6-speed manual gearbox. The same B38 engine family is used in the BMW X1 sDrive18i and the MINI Cooper 1.5. Even so, we check the engine code and specification against your registration before supplying an engine.

Reconditioned or Used: Clear Advice on Both Options

A reconditioned B38 comes back with fresh wear parts and a known starting point. A used, low-mileage engine is the lower-cost route. We explain the differences in cost, condition and expected life so you can choose the right option.

Finding the Real Cause Before Replacing Anything

Coolant loss and misfires on the 18i can have several causes, including a leaking hose or thermostat housing, a failing ignition coil, or head gasket failure. We test properly first, so you aren't paying for an engine replacement your X2 doesn't need.

These are the engine jobs X2 18i owners bring to us most often, from head gasket repairs to complete engine replacement. Each one starts with an inspection and a clear quote, and no work begins without your approval.

Replacement Engine Supply and Fit

When a B38 has suffered serious internal damage, for example from overheating or oil starvation, a replacement engine is usually the most practical fix. We source a compatible 1.5 petrol unit, transfer or renew the ancillaries as needed, and fit it at our workshop. The engine then gets fresh oil, filters and coolant, a fault-code check and a road test. Your BMW X2 sDrive18i engine supply and fit quote covers the engine and labour together.

Head Gasket Failure and Coolant Loss Repair

Coolant loss is one of the most talked-about problems on the X2 18i. On the B38, a failing head gasket can let coolant escape externally or leak into a cylinder. Signs include white smoke, a misfire on start-up, or an expansion tank that keeps needing a top-up. We pressure-test the cooling system and check the coolant for combustion gases to confirm the cause. If the gasket has failed, we remove the cylinder head, check it for flatness, and fit a new gasket and bolts. Caught early, this repair can save the engine from overheating damage.

Reconditioned and Used B38 Engines

A reconditioned BMW X2 18i engine is stripped, inspected and rebuilt with new wear parts where they're needed, then tested before fitting. Depending on what the inspection finds, those parts can include gaskets, seals and bearings. A used, low-mileage B38 is the more affordable option, and we check it for oil condition, leaks and signs of overheating before supply. MINI Cooper 1.5 engines share the B38 design, but their ancillaries and software differ, so we confirm compatibility first. Both options carry our 6-month warranty.

Engine Rebuilds

If the damage is limited, for example after a short overheating episode, rebuilding your existing B38 can be the better-value choice. We strip the engine, measure wear, find out why it failed and quote only for the parts it needs. A BMW X2 18i engine rebuild keeps the original unit in your car. We'll compare the rebuild cost with a replacement so you can decide with confidence.

Misfire Repairs

A misfire on a three-cylinder engine is easy to feel, usually as shaking at idle, hesitation or a flashing engine light. Common causes include worn spark plugs, a failing ignition coil or fuel injector, and on the B38, coolant getting into a cylinder. We read the fault codes, test each cylinder and check compression where needed. That way, a misfire that comes with coolant loss is investigated properly rather than treated as a simple coil fault.

Turbo Replacement

A failing turbo on the 1.5 petrol engine can cause a lack of power, whistling, smoke or limp mode. Turbo damage is often linked to oil supply problems or contamination, so we check the feed and return lines and the oil condition before fitting a replacement. That helps the new turbo last and protects the rest of the engine.

Timing Chain and Oil Leak Repairs

Like other BMW B-series engines, the B38 has its timing chain at the gearbox end, so replacing it usually means removing the engine. A rattle on start-up or timing-related fault codes are the warning signs. We also repair oil leaks from gaskets and seals around the cylinder head and sump, which can damage belts and wiring if left. Every repair starts with confirming exactly where the problem is.

Our workshop in West Thurrock (RM20 4EL) sits just across the Dartford Crossing from South East London. Drivers from Bexley, Sidcup, Thamesmead, Erith and Greenwich can reach us via the A2 or A206.

Getting Your X2 18i to Our Workshop

If your car is driveable, book a drop-off and come across the Dartford Crossing. The crossing charge is paid separately through Dart Charge. If the engine is overheating, has failed or isn't safe to drive, don't keep driving it. Call us to discuss how to get it to the workshop, and we'll keep you updated at every stage.

6-Month Warranty on Every Engine We Fit

Reconditioned and used BMW X2 sDrive18i engines that we supply and fit carry a 6-month warranty. If a covered fault appears during that time, contact us and we'll inspect the car and explain the next steps. Ask for the full terms before booking.
