If you're searching for BMW 118d timing chain replacement cost, it's important to know that there isn't a fixed price. The work required depends on the engine fitted to your vehicle, its condition, mileage, and whether any additional components need replacing.
At Bimmer Garage Nottingham, we specialise in BMW diesel timing chain inspections and replacements, helping owners prevent costly engine damage through early diagnosis.
Does the BMW 118d Have a Timing Chain?
Yes. Every BMW 118d diesel is fitted with a timing chain, not a timing belt.
Depending on the model year, your BMW 118d may have one of these engines:
- M47 2.0 diesel – Earlier E87 models
- N47 2.0 diesel – Many E87 and early F20 models
- B47 2.0 diesel – Later F20 models
The N47 engine is the one most commonly associated with timing chain wear.
Common Symptoms of Timing Chain Wear
A worn timing chain often gives warning signs before it fails.
Look out for:
- Metallic rattling on a cold start
- Rattling noise from the rear of the engine
- Engine management warning light
- Rough idle
- Reduced engine performance
- Difficult starting
- Timing-related fault codes
If you notice any of these symptoms, it's important to have your BMW inspected as soon as possible.
Why Do Timing Chains Wear?
Several factors can contribute to premature timing chain wear, including:
- Extended oil change intervals
- Incorrect engine oil
- Low engine oil level
- High mileage
- Worn timing chain guides
- Weak chain tensioner
Regular servicing with the correct oil can significantly extend the life of the timing chain.
What Is Included in a Timing Chain Replacement?
A professional timing chain replacement should include:
- New timing chain
- New chain guides
- New timing chain tensioner
- Replacement seals and gaskets where required
- Fresh engine oil and oil filter
- Timing verification using specialist tools
- Complete diagnostic checks
Replacing the complete timing chain system helps ensure long-term reliability.
Can You Continue Driving With a Noisy Timing Chain?
It is not recommended.
Driving with a worn timing chain increases the risk of:
- Timing chain failure
- Bent valves
- Damaged pistons
- Severe engine damage
- Complete engine failure
Early diagnosis is always the safest and most cost-effective approach.

The exact cost of a BMW 118d timing chain replacement depends on the engine variant, the condition of the timing components, and whether any additional repairs are required. Timing chain replacement on the N47 engine is labour-intensive because the chain is mounted at the rear of the engine.
