Common Failure
Timing chain tensioner failure is a well-documented issue on the N13 engine. The original timing chain guides and tensioners were prone to premature wear, leading to chain stretch, rattling noises, and in severe cases, catastrophic engine failure. Typical failure mileage: 50,000-80,000 miles. BMW did not formally acknowledge this issue for the N13 in the UK/EU market.
The BMW 1 Series 114i uses the turbocharged N13 engine family - a 1.6-litre four-cylinder that delivers 102 hp. While economical and pleasant around town, the N13 has a well-documented weakness: the timing chain system. Replacement demand for the BMW 114i is almost entirely driven by timing chain failure, with owners searching for "114i timing chain" and "114i engine replacement" when the tell-tale rattle appears. Every rebuilt N13 engine supplied through EnginesMarket includes upgraded timing chain components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.
Why the BMW 1 Series 114i N13 Engine Fails Prematurely

Typical Failure Mileage
50,000-80,000 miles
Root Cause
The timing chain, guides, and tensioners on BMW's N13 engine were poorly designed and constructed. The tensioner can fail, allowing the chain to become slack, which then rubs against the guides. Because the N13 is an interference engine, a stretched or snapped timing chain can cause pistons to collide with valves - resulting in catastrophic engine failure.

Vehicle Value Check
Vehicle Value Check
A typical 2012-2015 BMW 1 Series 114i is currently valued at approximately £3,000-£7,000 depending on mileage and condition [THIRD-PARTY - Auto Trader / Parkers market observation]. This places the 114i in the "repair or used engine typically makes more sense than a full rebuilt unit" bracket for lower-value examples. If your 114i is worth under £4,000 and the engine has suffered catastrophic timing chain failure, evaluate scrap value first - replacement cost may approach or exceed the car's market value. For well-maintained, higher-spec examples (M Sport, low mileage) worth £5,000+, a reconditioned or rebuilt engine with warranty is a viable investment.
Our Recommendation
Our Recommendation
If you hear the characteristic "death rattle" from the timing chain on cold start, act immediately. A £800-£1,200 specialist timing chain replacement is far cheaper than a full engine rebuild. If the chain has already snapped, the repair bill often exceeds the car's value - in that scenario, compare rebuilt engine prices through EnginesMarket against the cost of replacing the car. For owners planning to keep their 114i for 2+ years, a reconditioned N13 with upgraded timing components and warranty offers genuine peace of mind.

BMW 1 Series 114i Engine ReplacementFrequently Asked Questions
Question 1How much does a BMW 1 Series 114i engine replacement cost-
A BMW 1 Series 114i engine replacement typically costs £1,695-£2,600 for a reconditioned or rebuilt N13B16A unit supply-only. With supply and fit, expect £2,500-£3,800 depending on the specialist and location.
- Used N13B16A engines: £1,250-£1,600
- Reconditioned N13B16A: £1,695-£2,100
- Rebuilt N13B16A with warranty: £1,900-£2,600
Question 2What are the signs of timing chain failure in a BMW 114i-
The most common warning signs of N13 timing chain failure in a BMW 1 Series 114i include a rattling noise from the engine on cold start (the "death rattle"), rough idling, poor engine performance, and in later stages, the engine management light illuminating.
- Rattling noise lasting 1-2 seconds on cold start is the earliest warning
- Ignoring the rattle can lead to chain skipping or snapping
- A snapped timing chain on an N13 engine usually means catastrophic engine damage
Question 3Is it worth replacing the engine in a BMW 1 Series 114i-
A 2012-2015 BMW 1 Series 114i is typically valued at £3,000-£7,000. If your 114i is worth under £4,000, a full rebuilt engine may not be economically viable - consider a used engine or scrap the car. If your car is worth £5,000+ (low mileage, M Sport spec, good condition), a reconditioned engine with warranty is a sound investment.
- Vehicle value is the key factor in the decision
- Used engines offer a budget-friendly alternative
- Rebuilt engines with warranty suit owners keeping the car 2+ years
Question 4How long does a BMW 1 Series 114i engine replacement take-
A BMW 1 Series 114i engine replacement typically takes 2-3 days for a specialist to complete, including removal of the old N13 unit and fitting the replacement. Timing chain replacement alone (without full engine removal) can be completed in 1-2 days.
- Supply-only: engine delivered next working day in many cases
- Supply and fit: allow 2-3 working days
- Mobile fitting options available through some specialists
Question 5What's the difference between the BMW 114i and 116i engines-
Both the BMW 114i and 116i use the same N13 family of 1.6-litre turbocharged petrol engines, but with different power outputs. The 114i produces 102 hp (75 kW), while the 116i produces 136 hp (100 kW). The underlying engine block and many components are shared, but the 116i has a different ECU map and potentially different turbo hardware.
- Same N13 engine family - many parts are interchangeable
- 114i: 102 hp, 180 Nm torque
- 116i: 136 hp, 220 Nm torque
Question 6Does a BMW 1 Series 114i rebuilt engine come with a warranty-
Yes - every rebuilt BMW 1 Series 114i engine supplied through EnginesMarket comes with a minimum 12-month unlimited-mileage warranty. This covers the engine against manufacturing defects and component failure, giving you peace of mind when investing in a replacement N13 unit.
- 12-month warranty is standard on all rebuilt engines
- Some specialists offer extended warranty options
- Always confirm exact warranty terms with your chosen supplier
