What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The E60 M5's screaming S85 5.0L V10 shares the M-division rod-bearing weakness: marginal bearing clearances mean the rod bearings wear prematurely, ticking at low rpm and eventually spinning a bearing and destroying the engine. Preventive replacement (often every ~80,000-100,000 km) is considered essential maintenance, not optional. A cheap E60 M5 with no bearing history is a large financial risk - engine rebuilds run into five figures - so bearing history is the make-or-break check.

What you would notice

  • Ticking or knocking at low rpm
  • Falling oil pressure
  • Metal in the oil / on the sump magnet
  • Rumble on start-up

How to check it

Where to look. Connecting-rod bearings inside the 5.0L V10 bottom end

Demand documented rod-bearing replacement with km. Listen for a low-rpm tick, ideally get an oil analysis, and budget heavily if bearings are unknown. A specialist pre-purchase inspection on an E60 M5 is money well spent.

What it costs to put right

≈A$3,680 to ≈A$7,360 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Have the rod bearings been replaced, and when?”
  • “Any ticking at idle, and what does the oil look like?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car still has money owing on it, has been written off or reported stolen, what kms it showed in past sale ads, whether it has had accident repair claims and what it is worth today. That comes from the official records for that plate. Enter the plate and its state for the A$17.90 Vehicle Check, or the full history from A$24.99.

How much does it cost to fix on a BMW 5 Series?

≈A$3,680 to ≈A$7,360 at independent workshop rates, shown as an approximate guide in Australian dollars. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which BMW 5 Series years are affected?

Our research records this fault on the 2005–2010 BMW 5 Series.
