Common Failure
The M270 2.0-litre engine is significantly more robust than the 1.6-litre version, but suffers from occasional high-pressure fuel pump (HPFP) failure, which can send metal debris through the fuel system. Timing chain stretch has also been reported, particularly on higher-mileage units with delayed oil changes.
The Mercedes CLA 250 is powered by two generations of 2.0-litre turbocharged petrol engines. The first-generation M270 (2013-2019) is significantly more robust than the smaller 1.6-litre M270 units found in CLA 180 and CLA 200 models, but does have known weak points including high-pressure fuel pump failure and timing chain stretch. The second-generation M260 (2019-present) suffers primarily from oil consumption due to piston ring wear. Every rebuilt engine supplied through EnginesMarket includes upgraded components designed to address the original failure point - plus a minimum 12-month unlimited mileage warranty.

Affected Vehicles
Mercedes CLA 250 (M270 DE20 AL, 2013-2019)
Typical Failure Mileage
60,000-90,000 miles
Root Cause
The high-pressure fuel pump sheds metal internally, sending debris through the fuel rail and into injectors. Contaminated fuel or pump manufacturing defects are the primary causes. Once the HPFP fails, the entire fuel system is compromised.

Our Recommendation
Our Recommendation
HPFP failure is one of those repairs where trying to cut corners backfires. If the pump has failed, replace the entire high-pressure fuel system at the same time. Specialist cost of £1,600-£2,200 is steep, but ignoring contamination leads to a £2,800-£4,500 engine replacement.

Mercedes CLA 250 Engine ReplacementFrequently Asked Questions
Question 1How much does a Mercedes CLA 250 engine replacement cost in the UK-
A Mercedes CLA 250 replacement engine typically costs between £1,200 for a used M270 unit and £4,800 for a rebuilt M260 engine. Specialist fitting adds £450-£800.
- Used M270/M260 engines: £1,200-£3,000 depending on mileage and condition
- Rebuilt M270 units: £2,800-£4,500 supply only
- Rebuilt M260 units: £3,000-£4,800 supply only
- Specialist fitting adds £450-£800; dealer labour is significantly higher
- 12-month warranty included on all rebuilt units through EnginesMarket
Question 2Is the Mercedes CLA 250 engine reliable- What problems should I watch for-
The CLA 250's 2.0-litre turbo petrol engine is significantly more robust than the smaller 1.6-litre M270 units found in CLA 180 and CLA 200 models. However, the M270 (2013-2019) can suffer from high-pressure fuel pump failure and timing chain stretch, while the M260 (2019+) has reported oil consumption issues.
- M270 HPFP failure sends metal debris through the fuel system
- M270 timing chain rattling on cold start signals imminent tensioner failure
- M260 oil consumption due to piston ring wear (40k-70k miles)
- Regular oil changes every 10,000 miles significantly extend life
Question 3How long do Mercedes CLA 250 engines last-
Well-maintained M270 2.0-litre petrol engines regularly reach 120,000-150,000 miles. M260 2.0-litre units are too new for full longevity data but are expected to achieve similar mileage with proper maintenance.
- M270 (2013-2019): 120k-150k miles with regular servicing
- M260 (2019+): promising design but oil consumption requires attention from 40k miles
- Regular oil changes every 10,000 miles (not Mercedes' 15,000-18,000 mile interval) significantly extends life
Question 4Which Mercedes CLA 250 engine should I avoid when buying used-
The M270 2.0-litre engine in the CLA 250 (2013-2019) is significantly more reliable than the 1.6-litre M270 found in CLA 180/200 models, but pre-2014 units have higher timing chain failure rates.
- 2013-2014 M270: monitor for timing chain rattle
- 2015-2019 M270: improved but HPFP failure is the main concern
- 2019+ M260: oil consumption is the main issue; check for service history with regular oil changes
- Always check service history for regular oil changes using Mercedes-approved oil
Question 5How much does timing chain replacement cost on a Mercedes CLA 250-
Timing chain replacement on a CLA 250 M270 engine costs £1,200-£1,800 at a specialist or £1,800-£2,500 at a main dealer. This is preventative work. If the chain has already slipped, full engine replacement at £2,800-£4,500 is required.
- Specialist preventative chain/tensioner replacement: £1,200-£1,800
- Dealer pricing for same work: £1,800-£2,500
- Rattling noise on cold start for 1-2 seconds is the early warning sign
- Once timing jumps, valves contact pistons - engine is beyond repair
Question 6Is it worth replacing the engine on a Mercedes CLA 250-
Yes, if the car is otherwise sound. A CLA 250 worth £8,000-£12,000 with a failed M270 engine justifies a £2,800-£4,500 rebuilt engine. For newer M260-equipped CLA 250s worth £15,000+, replacement is almost always worthwhile.
- CLA 250 with good body/interior: replacement engine is cost-effective
- Specialist rebuilt engines fix original design weaknesses and include warranty
- Compare against £4,000-£5,500 main dealer new engine quotes
Question 7Mercedes CLA 250 vs CLA 250 4MATIC - is the engine the same-
Yes, the CLA 250 and CLA 250 4MATIC use the same engine in each generation (M270 DE20 AL or M260 DE20 AL). The difference is drivetrain - front-wheel drive versus all-wheel drive - not the engine itself.
- Both CLA 250 and CLA 250 4MATIC share the same 2.0L turbo petrol engine
- 4MATIC adds approximately 1-2 hours to engine fitting labour due to additional drivetrain components
- Engine replacement costs are otherwise identical
