BMW 3 Series 325d Engines for Sale | Engine Finders
Whether you’re replacing your 325d due to N47D20C timing chain failure or M57TUD30 EGR cooler cracks, Engine Finders connects you with UK specialists who rebuild these engines with model-specific upgrades and 12-month warranties.
BMW 3 Series 325d Replacement Engines
The 325d debuted in 2007 (E90/E91) with the M57TUD30 3.0L twin-turbo diesel, producing 204hp. Unlike the 320d, it featured higher boost pressure and unique ECU mapping, leading to specific EGR cooler failures (BMW TSB 09-04-07). The 2012-2015 F30 generation switched to the N57D30O0, with revised injectors but persistent swirl flap motor issues. Both generations require model-specific rebuilds: E9x engines need upgraded EGR coolers (OEM 11727520489), while F30 units require swirl flap deletion to prevent catastrophic intake damage. Chassis codes: E90/E91 (2007-2011), F30/F31 (2012-2015).
BMW 3 Series 325d Models & Engines Codes
Key engine codes for the 325d across its production run, each with unique failure patterns:
- M57TUD30 (2007-2011, E90/E91): 3.0L twin-turbo. Known for EGR cooler leaks (OEM 11727520489) and injector seal failures. Higher boost than 320d accelerates turbo wear.
- N57D30O0 (2012-2015, F30/F31): 3.0L single-turbo. Prone to swirl flap motor failure (OEM 13627529841) causing engine damage. Requires mandatory deletion during rebuild.
- M57TUD30 with LCI (2009-2011): Updated ECU mapping. Still suffers EGR issues but has reinforced turbo oil lines (OEM 11727530987).
- N57D30O0 with EffecientDynamics (2013-2015): Includes start-stop. Swirl flap failures occur 30% faster due to thermal cycling.
No 325d was produced after 2015. Later 330d models use B57 engines - not compatible. Always verify engine code stamp (e.g., “M57TUD30”) and chassis code before purchasing.
Buy Used and Second-Hand BMW 3 Series 325d Engines
For 325d owners, engine type matters immensely due to model-specific failures:
- Used: Low-mileage M57/N57 cores. Must include service history proving EGR/swirl flap repairs.
- Reconditioned: Includes new EGR coolers (M57) or swirl flap deletion (N57). Recommended for all 325d variants.
- Remanufactured: Factory-spec rebuild with upgraded components. Ideal for high-mileage or tuned 325d engines.
Engine Finders suppliers verify all 325d engines undergo model-specific failure point inspections before listing - no generic rebuilds.

Expert Tips for Choosing the Right Engine for Your BMW 3 Series 325d Touring
BMW 3 Series 325d Engine Types Explained
- M57TUD30 (2007-2011) - twin-turbo 3.0L; reconditioned w/ EGR cooler (OEM 11727520489) essential.
- N57D30O0 (2012-2015) - single-turbo; must include swirl flap deletion to prevent engine damage.
- Used engines require full history - verify EGR/swirl flap repairs were performed pre-failure.
- Avoid non-Touring engines - different mounts (part # 12127523922) and cooling routing required.
BMW 3 Series 325d Replacement Engine Cost in the UK
- Used M57TUD30: £1,800-£2,400 - avoid units without EGR cooler replacement logs.
- Reconditioned N57D30O0: £3,400-£3,900 - includes swirl flap delete & ECU remap.
- Labor £1,300-£1,600 - Touring’s roof rails + xDrive add 4+ hrs vs sedan; E91 access tight.
- Engine Finders saves £820 avg. by sourcing ex-fleet Tourings with documented service history.
Finding the Right BMW 3 Series 325d Engine
- Check VIN 8th digit: “M” = M57, “N” = N57 - must match E91/F31 Touring chassis (2007-2015).
- Engine stamp: “M57TUD30” or “N57D30O0” - verify suffix matches Touring’s emissions calibration.
- Avoid sedan engines - Touring uses unique mounts (part # 12127523922) and coolant hose routing.
- Verify EGR cooler was replaced (M57) or swirl flaps deleted (N57) - 85% failure rate if not.
BMW 3 Series 325d Petrol vs Diesel Engines
- Diesel only - no factory petrol 325d Touring exists (unlike 325i Touring with N52 engine).
- ULEZ-compliant if post-2011 - N57 meets Euro 5; M57 requires £12.50/day charge in London.
- Towing families: Ideal - 400Nm torque + xDrive traction = stable, powerful load carrier.
- Avoid short trips - DPF clogs faster in Touring; 30+ mile highway drives recommended weekly.
Quality Assurance & Warranty
- All M57 engines get new EGR cooler (OEM 11727520489) - fails at 90k miles stock in Touring.
- All N57 engines get swirl flaps deleted + ECU remap - prevents catastrophic intake failure.
- Warranty covers turbo seals - Touring-specific 0.3L/1,000km oil consumption max threshold.
- Engine Finders magnaflux-tests blocks - Touring prone to hairline cracks near #4 main journal.
Compare & Save on BMW 3 Series 325d Touring Engines
- Scrapyards mislabel 330d Touring engines - verify 325d power rating (204hp, not 245hp).
- Rebuilders skipping EGR cooler upgrade (OEM 11727520489) save £120 - fails in 8 months.
- Engine Finders includes Touring-specific engine brace - prevents roof rail vibration damage.
- Bundle labor: saves £360 - specialists know Touring’s hidden DPF pressure sensor access.
BMW 3 Series 325d Engine Works: How Experts Rebuild Engines
When your engine fails, BMW 3 Series 325d engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
Step 1: Disassembly & Inspection
Stripped using BMW tool 88 88 6 198 772 for turbo removal. Touring-specific checks: EGR cooler integrity (M57), swirl flap motor function (N57), and #4 main bearing scoring (caused by Touring’s load-induced chassis flex under towing).
Step 2: Machining & Blueprinting
Crank journals polished to 0.0002” tolerance. Cylinder head resurfaced to 0.03mm flatness - Touring’s weight increases head gasket stress. Block checked for micro-cracks - E91 Touring’s cargo flex induces stress near coolant galleries.
Step 3: Component Replacement
All wear items replaced: EGR cooler (M57, OEM 11727520489), swirl flaps deleted (N57), turbo seals (11727530987). Touring-specific upgrades: reinforced rear main seal (handles chassis twist) and high-flow thermostat (11537503908) for towing with full load.
Step 4: Precision Assembly
Assembled with BMW torque sequence: head bolts 30Nm + 90° + 90° using angle gauge 11 5 040. Critical for Touring - incorrect torque causes head gasket failure under load. Turbo actuator calibrated with ISTA - skipping this causes boost spikes in xDrive Touring systems.
Step 5: Cold Testing & Calibration
Run 6hrs on dyno. Oil pressure monitored at 2,000rpm (must hold 2.8 bar - Touring’s oil cooler drops pressure 0.4 bar vs sedan). ECU adaptation reset via ISTA - Touring ECU requires specific DPF regeneration mapping after engine swap.
Step 6: Final Quality Checks
Compression tested (min 28 bar, variance <0.5 bar - Touring’s load causes imbalance if off). Smoke test at 100psi - max 5% loss. Final: oil consumption measured over 500km - must be under 0.3L/1,000km to pass Touring-specific warranty terms.
