BMW E60 Timing Chain: Rattling Noise and the Cost-Sharing Program
Quick summary. A metallic rattle at 1500–1800 rpm is an early sign of timing chain stretch in the BMW E60’s 2.0-liter engine. At the first sign of the noise, get to an authorized BMW service center right away: BMW has launched a cost-sharing program that covers the chain replacement. On early versions, chain life is just 37,000–50,000 miles.
The Problem
You get into your BMW E60, pull away—and under acceleration you hear a metallic rattle, like jingling chains. Sound familiar? This isn’t just some stray noise; it’s a signal that the timing chain has stretched. In the 2.0-liter four-cylinder, design features lead to premature wear of the upper chain. Ignore the symptom and you risk a snapped chain, damaged valves and pistons—maybe even a replacement engine.
Symptoms
- Metallic rattle at 1500–1800 rpm
- Fluctuating idle speed
- Camshaft timing faults (P0012)
- Sluggish acceleration
Causes
The engine uses a double-row chain, but the problem lives in the tensioning system. Poor lubrication and high thermal loads wear out the plastic guides and slip rails: they lose their shape and stop holding the chain. A chain reaction follows—the loose chain accelerates its own stretching, and the stretched chain overloads the tensioner.
Why 1500–1800 rpm specifically? At idle the chain runs quietly, and at high rpm engine noise masks the rattle. In the sweet spot in between, resonance from the chain and the worn guides becomes clearly audible.
Even with gentle use, chain life on early versions of the engine is just 37,000–50,000 miles. Repair statistics confirm the problem is systemic: the crankshaft was changed several times, the counterweights seven times, the tensioner kits three times.
The Fix
Step 1. Get to an authorized BMW service center. Don’t put it off: every day of driving with a stretched chain raises the odds of it snapping.
Step 2. Ask for a chain tension test. The dealer will run diagnostics and pinpoint exactly how far the chain has stretched and how worn the guides are.
Step 3. Replace the entire chain kit. That means the upper and lower chains, guides, slip rails, tensioner and, if needed, the sprockets. Skimp on any of it and you’ll be back in the shop within 12,000–19,000 miles.
The BMW cost-sharing program. There was never an official recall, but BMW launched a program of spot inspections and repairs. Once the defect is confirmed, the company pays for the labor and all components—chain, guides, slip rails, tensioner. The customer covers only the fluids: coolant and oil. After the repair, the warranty runs 7 years or 124,000 miles.
Used BMW E60 Buying Checklist
- Check for the rattle at 1500–1800 rpm
- Ask whether the chain was replaced under the cost-sharing program
- Request the repair paperwork and check the date—the warranty runs 7 years or 124,000 miles
- Verify a complete service history with records of oil changes
Updates After March 2011
From March 2011 on, the problem shrank dramatically: engineers changed the guide materials, strengthened the tensioner, and improved the lubrication system. The crankshaft, counterweights, and tensioner kits were all replaced. The odds of trouble on engines built after that date are far lower, but it’s not a full guarantee—hard use can still produce the defect. Regardless of model year, have the chain checked at an authorized service center.
The Bottom Line
A rattle at 1500–1800 rpm is an early sign of timing chain stretch and calls for an immediate visit to the service center. BMW’s cost-sharing program covers the chain replacement with a 7-year or 124,000-mile warranty. Buying a used E60? Check for the noise and ask for the repair paperwork—that’s what keeps a serious repair bill away.
