Reconditioned BMW 3 Series Engine for Sale with Up to 40% Discount & Warranty

Replacement BMW 3 Series Engine Supply & Fit Service with Up to 24 Month Warranty

At BM Engine Works, we focus on a single goal: keeping every BMW 3 Series car—whether it is a BMW E90 320d diesel or the latest BMW 3 Series XB1141O1 B48B20B PHEV 2.0 petrol hybrid—running with power, refinement and peace of mind. Our Rainham based workshop holds one of the largest stocks of quality used and reconditioned engines for the BMW 3 Series car in the UK. Each replacement engine is compression tested, inspected and ready to fit, so you spend less time waiting and more time driving. We supply nationwide and, if you choose our in house fitting team, we will even recover your vehicle and return it road ready with a free warranty for up to twelve months.

Because we rebuild in house and partner with trusted suppliers, our online prices are typically up to 40% lower than main dealer quotes, meaning you get a quality engine at the cheapest online price. Yet every engine leaves the bench with genuine gaskets, fresh fluids, and dyno sign off. That blend of affordability and factory grade quality has made us one of the most trusted engine specialists in the UK.

What is the common problem with the BMW 3 Series engines?

Across the generations, BMW 3 Series engines remain dependable, but each model or engine code has its own common engine problems. On early N47 2.0 litre diesel units, a stretched or snapping timing chain is the best known issue, often flagging the need for engine repair with a metallic rattle on cold start. Later, B series diesels solved most of the chain wear, yet even they benefit from regular oil changes. Petrol cars can suffer from VANOS solenoid sticking, oil filter housing leaks and high pressure fuel pump failure. Keeping fresh oil, OEM filters and using quality diesel or petrol prevents nine out of ten failures reported by owners.

How much does a replacement BMW 3 Series engine cost online?

Prices for our car engines for sale vary with engine code, type and condition. A quality used BMW 3 Series engine starts from hundreds of pounds, while a fully reconditioned BMW 3 Series complete engine from our range of reconditioned and used engines costs more because of new bearings, chains, seals and machine work. Thanks to our volume purchasing and in house rebuild facility, online quotes through our “Get Quote” tool are commonly 30–40% cheaper than a franchised dealer offering only brand new units. Taxes, fitting and delivery are itemised up front, so you know the exact figure before we turn a spanner.

Where can you buy a reconditioned BMW 3 Series engine for sale in the UK online?

You are already in the right place. When you shop BMW engines with us, our store lists every engine we sell—reconditioned and used—alongside mileage, engine code and build specification. Stock spans M47, N20, N47, N54, the BMW 3 series engine XB1141O1 B48B20B PHEV 2.0, and the sought after S55 for M3 models. Each of our BMW 3 Series reconditioned engines is stripped to the bare block, cleaned, honed, then rebuilt with new OEM pistons or rings, chains, gaskets and seals before bench testing. A certificate of build accompanies every unit for your records. UK wide delivery or supply, and fit at our Essex workshop is available, ensuring you get the engine you need promptly.

Is a second hand BMW 3 Series complete engine a reliable replacement option?

Yes—provided the second hand engine comes from a reputable supplier, is low mileage and is properly inspected. Our quality used and reconditioned BMW 3 Series engine stock is sourced from late model salvage with full service history, providing an affordable used BMW engine option. We run a compression and leak down test, inspect the timing components, replace service items and record evidence before shipment to ensure you receive a quality engine. That is why we can offer a free warranty on every second hand BMW 3 Series engine we dispatch, giving peace of mind that you would expect from a reconditioned unit at a lower price point.

What advantages do our used or reconditioned BMW 3 Series engines offer?

• Cost saving: Buying a reconditioned and used BMW 3 Series engine from us can save thousands versus fitting a new engine.
• OEM standards: Our reconditioned engines offer a rebuild to original tolerances using BMW or equivalent parts.
• Environmental benefit: Choosing a second hand or rebuilt unit means one less new engine needs to be manufactured.
• Free warranty: Up to 24 months' cover is included for every type and condition of engine we sell, whether 320d diesel, 2.0 petrol or hybrid.
• Fast turnaround: Large on shelf stock and UK wide delivery minimise downtime.

These advantages make a replacement engine for BMW 3 Series from us a smart, sustainable and wallet friendly choice.

How do online prices for BMW 3 Series engine parts compare to dealer quotes?

Dealer parts come with a premium price tag and are limited to current stock. Our online catalogue lists new, used engine parts and re machined components—blocks, cylinder heads, injectors, turbos—at a fraction of dealership RRP. Discounts come from bulk buying and in house machining. For example, an OEM timing chain kit for an N47 diesel can be 35% less on our parts portal, and a remanufactured turbo for an E90 320d diesel engine is typically half the showroom price. Because prices update by day, you should always contact us to get the cheapest price available that day.

Can I select my BMW 3 Series engine replacement by model year and spec?

Absolutely. Use the “Select Your BMW 3 Series” tool to pick from all BMW 3 Series models (E36, E46, E90, F30, G20), engine size (1.6, 2.0, 3.0, etc.) and fuel type to find the right engine for your BMW 3 Series car. The catalogue then filters every engine we sell, from second hand BMW 3 Series E90 320d diesels to the latest B48B20B PHEV 2.0 petrol hybrid. If you already have your engine code like N57D30A, M57D30 or N47D20A, we can match it instantly. Not sure which version you need? Contact us with your registration, and we will confirm the exact unit, ensuring a fit when you order.

Why are BMW 3 Series engine replacements the cheapest online with our shop?

2. Direct supply chain: Engines come straight from auctions, insurers and fleet disposals—no middlemen.
3. High volume sales: Moving hundreds of engines each month lets us keep margins low while including a free warranty.
