How much does a BMW 2 Series F22 engine replacement cost in the UK?

A reconditioned F22 engine typically costs £2,500–£12,000 supply only [BMW-QUOTE], depending on the engine -the four-cylinder petrols sit at £2,500–£4,500, the B58 at £4,500–£7,000, and the S55 M2 Competition at £6,000–£12,000. Fitting adds £520–£1,170. Use our calculator for a personalised figure.

Which F22 engine is the most reliable?

The B58B30O0 (M240i, 2016–2021) is the F22's most reliable engine -BMW's modern turbocharged straight-six is smooth, responsive, and genuinely robust, addressing many of the N55's weaknesses. The B48 four-cylinder is also very reliable, and the B47 diesel is improved over the N47.

What are the common problems with the BMW 2 Series F22?

The N20 four-cylinder (pre-2015) suffers from timing chain guide wear -a failure that can destroy the engine. The N55 six-cylinder (M235i, M2) has oil leaks and charge pipe failures. The S55 (M2 Competition) has a known crank hub spin risk. Diesels: the N47 has timing chain issues (pre-2015), while the B47 is improved.

Is the BMW 2 Series F22 reliable?

It depends heavily on the engine and year. The B48, B58, and B47 (post-2015) are the most reliable. The N20 and N47 (pre-2015) carry timing chain risks. The N55 is decent but has oil leak and charge pipe issues. The S55 is robust for a high-performance engine but requires diligent maintenance and budgeting for crank hub work.

Which F22 engine should I avoid?

Pre-2015 N20 (220i/228i) without documented timing chain replacement -it's a well-known weakness. Also avoid pre-2015 N47 diesel without chain history. The S55 M2 Competition is fantastic but expensive to maintain; if you're not prepared for that, skip it. Any engine without full service history is a risk.

How do I know if my F22 engine needs replacing?

Timing chain rattle on cold start (N20, N47), oil leaks or loss of boost (N55), crank hub symptoms like misfire or timing codes (S55), persistent warning lights, or coolant loss are the key warning signs. Use our diagnostic calculator for a personalised assessment.

Is it worth replacing an F22 engine, or should I scrap the car?

Depends on the car's value. Against a £15,000 M240i, a £4,500–£7,000 B58 recon is 30–47% -well within our 70% BMW threshold. Against a £8,000 228i, a £2,500–£4,500 N20 recon is 31–56% -borderline but often viable for a well-kept example. For an M2 Competition at £25,000+, a £6,000–£10,000 S55 recon is 24–40% -a repair decision, not a scrap question. Value the car first; if it's a pre-2015 N20 without chain history, walk away or budget for the work immediately.

How long do F22 engines last?

The B58 and B48 can comfortably exceed 150,000 miles with proper servicing. The N55 is capable of high mileage but oil leaks and charge pipe issues require attention around 60k–100k miles. The N20's timing chain is the limiting factor -addressed proactively, it can reach 100,000+ miles. The S55 is robust but high-strung; treat 50,000 miles as a major service checkpoint.

What is the difference between the F22, F23, and F87?

The F22 is the 2 Series coupé (this page). The F23 is the 2 Series convertible -it shares the same platform and engines but has a folding soft top and slightly different chassis bracing. The F87 is the M2 -a high-performance version of the 2 Series, with a wider track, aggressive bodywork, and more powerful engines (N55B30T0 or S55). The F87 is covered on its own Generation Page.

How do I find my F22 engine code?

Listed on the VIN plate and vehicle documentation; the engine code is also stamped on the cylinder block. For petrol: N20B20 (early 220i/228i), N55B30O0 (M235i), B48B20 (later 220i/230i), B58B30O0 (M240i), N55B30T0 (M2), S55 (M2 Competition). For diesel: N47D20O1 (early 218d/220d) or B47D20 (later).

Overview

BMW 2 Series F22 -Overview

The F22 is the first generation of the BMW 2 Series coupé, launched in November 2013 as the successor to the E82 1 Series coupé.

Designed by Christopher Weil, it introduced a new naming convention for BMW's compact rear-wheel-drive models, reviving the spirit of the legendary BMW 2002. Built on a shortened version of the F30 3 Series platform, the F22 features a 50:50 weight distribution, MacPherson strut front suspension, and a five-link rear setup. The engine line‑up evolved significantly: the launch N20 four‑cylinder and N55 six‑cylinder were replaced by the more modern B48 and B58 from 2016. The high‑performance M2 (F87) arrived in 2015, with the M2 Competition following in 2018. Production ended in 2021.

Best & Worst Engines

Best Value

B48B20 (230i)

“The B48 four-cylinder delivers 248 bhp -more than the N20 it replaced -with better reliability and fuel economy. It's the sensible choice that doesn't feel sensible: 0–60 in 5.6 seconds and a genuine 40+ mpg on a run.”

Who it's for: buyers who want daily-driver usability with genuine performance.

Highest Risk

N20B20 (early 220i/228i, pre‑2015)

“The N20's timing chain guide wear is well-documented -a failure that can destroy the engine. BMW revised the guides in 2015, but early cars remain a gamble without documented chain work. The plastic charge pipe is another common failure point.”

Who it's for: only buyers with documented timing chain replacement or post‑2015 cars.

Most Expensive Failure

S55 (M2 Competition)

“The S55 is a high‑performance version of the N55 with twin turbos and a closed‑deck block. It's robust for what it is, but parts are expensive, and a full engine replacement can exceed £10,000. The M2 CS's 444 bhp variant is even more costly.”

Who it's for: buyers with deep pockets who want the ultimate F22‑based M car.

Most Overlooked

N55B30T0 (M2, 2015–2018)

“The original M2's N55 is often overshadowed by the later S55‑powered Competition, but it's a more characterful engine -less clinical, more engaging. It's also cheaper to buy and maintain than the S55 cars.”

Who it's for: buyers who want M2 performance on a tighter budget and prefer character over outright pace.

The F22 rule

A £4,500–£7,000 B58 recon against a £10,000–£20,000 M240i sits at 23–70% of the car's value -at the upper end, that brushes our 70% BMW scrap threshold. Against a £15,000+ example, the same recon drops to 30–47% -a repair decision, not a scrap question. For an N20 228i at £8,000–£12,000, a £2,500–£4,500 recon is 21–56% -borderline but often viable for a well‑kept example. Value the car first; if it's a pre‑2015 N20 without timing chain history, walk away or budget for the work immediately.

Key Takeaways

Which F22 Costs Least To Own?
B48B20 (230i) -modern four‑cylinder, no major known issues, cheaper parts than the six‑cylinders.
Which F22 Costs Most To Own?
S55 (M2 Competition) -crank hub risk, expensive parts, high running costs.
Which F22 Is Best Value?
B58B30O0 (M240i) -the definitive F22 engine, modern reliability, strong performance.

Common Problems

01

N20

Timing Chain Guide Wear (Pre‑2015)

Affected models:

Typical failure mileage:

Root cause:

Tiered Cost Table

Our Recommendation

If you're buying a pre‑2015 N20 F22, look for documented timing chain work or budget £1,200–£2,500 immediately. A preventative chain and tensioner replacement is dramatically cheaper than the £2,500+ replacement that follows a failure. On a car worth under £8,000, evaluate carefully before committing.

02

N55

Oil Leaks & Charge Pipe Failure (M235i, M2)

Affected models:

Typical failure mileage:

Root cause:

Tiered Cost Table

Our Recommendation

If your N55 develops oil leaks or a loss of boost, have it inspected immediately -a £500–£1,200 gasket and charge pipe repair is far cheaper than the £4,000+ replacement that follows a catastrophic failure. On an M235i worth over £12,000, this is a manageable cost of ownership.

03

S55

Crank Hub Spin (M2 Competition)

Affected models:

Typical failure mileage:

Root cause:

Tiered Cost Table

Our Recommendation

If you're buying an M2 Competition, budget for a crank hub fix if the car is modified or you plan to modify it -£1,800–£3,000 is cheaper than the £6,000+ replacement that follows a failure. On a stock car, it's a risk you can manage, but the peace of mind is worth the cost.

04

N47

Timing Chain (Pre‑2015 Diesel)

Affected models:

Typical failure mileage:

Root cause:

Tiered Cost Table

Our Recommendation

At the first sign of cold‑start rattle, get the chain inspected immediately -a £650–£1,800 preventative repair is dramatically cheaper than the £3,200+ replacement that follows if ignored. On an F22 worth under £8,000, this decision alone determines whether the car stays economically viable.
