Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

Rod bearing wearS65B40€1,500–€2,800

Usually silent until it's not. Metal in the oil, then a knock, then a destroyed engine. Tight bearing clearances combined with low-viscosity oil and cold running wear the shells. BMW revised the bearing shells during production.

Check: Ask for a bearing replacement receipt or a recent oil analysis. This is the single question that decides an E9x M3 purchase. A car with documented bearings is worth several thousand more than one without, and it's cheaper to buy the done car.

Later parts: Revised bearing shells fitted later in production; most specialists still treat replacement as preventive maintenance around 100,000 km.

EnginecommonPartly detectableevidence: documented90–160k km

Dual-mass flywheel and clutch wearGetrag six-speed manual€900–€1,600

Rattle at idle with the clutch up that disappears when you press it, judder on pull-away, gearbox rumble. The dual-mass flywheel's springs wear. Diesels and tuned petrols wear them faster.

Check: Idle in neutral with the clutch up and listen, then press the clutch. A rattle that stops when you press is the flywheel. Also check for judder pulling away in first.

TransmissioncommonDetectable at viewingevidence: documented130–250k km

DCT mechatronic and clutch wearGetrag seven-speed M-DCT€1,500–€4,500

Jerky low-speed shifts, clutch adaptation faults, refusal to engage a gear, drivetrain warnings. The dual-clutch unit's clutch packs wear and the mechatronic unit's electronics and solenoids fail. Fluid service is required and often skipped.

Check: Drive it in traffic, not just on an open road. Low-speed crawling is where a tired DCT shows itself. Check the fluid service history; it needs doing roughly every 60,000 km.

TransmissionoccasionalPartly detectableevidence: documented90–180k km

Throttle actuator failureS65B40€800–€1,600

Engine warning light, limp mode, reduced power, actuator fault codes. The individual throttle body actuators wear internally. The V8 has two.

Check: Scan for actuator codes including stored history. Ask whether they've been replaced. Most cars have had at least one.

EnginecommonDetectable at viewingevidence: manufacturer80–180k km

Front control arm bushing wearE9x chassis€300–€700

Knocking over bad surfaces, vague or wandering steering, uneven front tyre wear, steering shimmy under braking. The front lower arm bushings are a known wear item on this chassis and go well before the ball joints.

Check: Drive over a rough road at low speed with the windows down and listen. Check the inside edges of the front tyres for feathering.

SuspensionuniversalDetectable at viewingevidence: documented80–150k km

Folding hardtop mechanism and hydraulic faultsE93 body€500–€2,500

The roof stops mid-cycle, refuses to operate, or throws a roof warning; hydraulic fluid weeping in the boot. Microswitches, hydraulic rams and the boot-floor mechanism all wear. A roof stuck half-open isn't a drivable car.

Check: Cycle the roof fully open and fully closed at least twice, watching for hesitation, and check the boot for fluid. A seller who won't demonstrate the roof is telling you it's broken.

ElectricaloccasionalDetectable at viewingevidence: documented

Run-flat tyres and kerbed or cracked wheelsE9x chassis€150–€900

Harsh ride, vibration at speed, slow punctures. Stiff-sidewall run-flats transmit impacts straight into the rim, and these alloys crack rather than bend.

Check: Inspect the inner rim edge of every wheel for cracks and hairline splits, not just the face for kerbing. Budget for a set of conventional tyres; most owners switch and the ride improves markedly.

SuspensioncommonDetectable at viewingevidence: documented

Roof drain blockage and boot water ingressE93 body€150–€900

Water in the boot or rear footwells, damp smell, corroded connectors under the carpet. The convertible's drain channels block, and the water goes into the car.

Check: Lift the boot carpet and the spare wheel cover, and press the rear footwell carpets with your palm. Damp here on a convertible is the start of an electrical problem, not the end of a cosmetic one.

Largely a non-issue on cars from southern Europe, a real one on northern and Baltic cars.Footwell module (FRM) failureTest every window, both mirrors, the wipers, all exterior lights and the central locking before you drive. If any cluster of these is dead, this is why.Rear shock mount wearLift the boot floor and look at the top of the shock towers for cracking or a lifted mount. Listen for a knock over bumps.iDrive CCC head unit failureTurn it on and use it for a few minutes: navigation, radio, settings. Reboots during that window are the fault showing itself.Coolant expansion tank crackingLook at the tank with the engine warm, dried coolant leaves a white or pink crust. Cheap to fix, but it tells you how the car has been maintained.

2On the driveInclude low-speed manoeuvring, not just an open road.

Check all four tyres are the same brand and wear, mismatched tyres destroy these.

3PaperworkOn these cars the folder is most of the value.

Rod bearing wearAsk for a bearing replacement receipt or a recent oil analysis. This is the single question that decides an E9x M3 purchase. A car with documented bearings is worth several thousand more than one without, and it's cheaper to buy the done car.Unregistered replacement batteryAsk when the battery was changed and whether it was registered. A car with a new battery, no registration and a scatter of odd electrical faults usually just needs coding.High oil consumptionBudget for it and check the level often. Consumption that's suddenly much worse than the car's own history is the warning sign, not consumption itself.

4OBD scanMandatory. A seller who refuses a scan has answered the question.

Throttle actuator failureScan for actuator codes including stored history. Ask whether they've been replaced. Most cars have had at least one.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

Mileage is nearly irrelevant next to the bearing question. A 150,000 km car with bearings, throttle actuators and a rebuilt history is a better purchase than a 60,000 km garage queen with none of it, because short-trip, rarely-warmed use is exactly what wears these bearings. So ask for oil analysis if there are no bearing receipts.

Service item	Interval	Cost
Rod bearings The entire ownership question, and the only genuinely dangerous failure	~100,000 km, preventive	€1,500–2,800
Engine oil A high-revving V8 with tight bearing clearances is unforgiving of tired oil	every 10,000 km or annually	€180–260
Throttle actuators Most cars have needed at least one; check for extended coverage	as they fail	€800–1,600

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record

There is no other engine like the S65 in a road car at this price: 8,300 rpm, individual throttle bodies, port injection so no carbon service, and a noise that justifies the fuel bill on its own. The ownership question is singular and unavoidable, rod bearings. Specialists treat replacement as maintenance around 100,000 km, and the car market has priced that in, so a documented car costs more and is nevertheless the cheaper car. Beyond that. Then budget for throttle actuators, an inspection-driven valve service, tyres, and roughly 15 l/100 km. Manuals are the enthusiast's choice; DCT cars are faster and need their own fluid service. Values are rising for good examples, which makes the wrong purchase expensive twice over.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
