BMW M3 (E90/E92) buying guide
The S65 V8 is the reason to buy this M3 and the thing to check first. Ask for receipts for connecting-rod bearing work, test for throttle actuator faults and idle problems, and look for valve cover oil leaks. A car without bearing records should be priced as if the job still has to be done.

Inspection checklist
Engine and records
- Connecting-rod bearing receipts
What to look for: Invoices with part numbers, date and mileage, ideally from an S65 specialist. Wear often gives no warning before damage is done.
- Idle and low-rpm noise
What to look for: Ticking or knocking at idle and low rpm points to bearing wear. An idle that hunts can point to the idle control valve or a vacuum leak.
- Fault memory
What to look for: Have the fault memory read. Throttle actuator faults cause limp mode and lost power; also look for misfire and gearbox entries.

Connecting-rod bearing wear
Severity: High- Affects
- S65 · All years
- Symptoms
- Ticking or knocking at idle and low rpm, metal particles in the oil or filter, loss of oil pressure. Premature wear is far more common than complete engine failure.
Throttle actuator failure
Severity: High- Affects
- S65 · All years; no typical mileage
- Symptoms
- Fault codes, limp mode and lost power. When one actuator fails, specialists usually replace both.
