Mercedes Benz CLA 180/200 Petrol Engine ReplacementCompare Prices & Get Quotes

A Mercedes CLA 180 or CLA 200 petrol replacement engine typically costs between £900 for a used unit and £3,500 for a rebuilt M270 engine, with M282 rebuilt units reaching £3,800. Specialist fitting adds £450-£800.

• Used M270/M282 engines: £900-£2,200 depending on mileage and condition
• Rebuilt M270 units: £1,800-£3,500 supply only
• Rebuilt M282 units: £2,200-£3,800 supply only
• Specialist fitting adds £450-£800; dealer labour is significantly higher
• 12-month warranty included on all rebuilt units through EnginesMarket

The M270 1.6-litre petrol in pre-2014 CLA 180 and CLA 200 models is the least reliable of the petrol range due to timing chain tensioner failure. Post-2019 M282 1.3-litre units are more reliable but can suffer from carbon build-up and cylinder deactivation issues.

• M270 timing chain rattling on cold start signals imminent tensioner failure
• Pre-2014 M270 units have the highest failure rate
• M282 engines require regular high-quality fuel to minimise carbon build-up
• Both engines benefit from oil changes every 10,000 miles (not Mercedes' 15,000-mile interval)

Well-maintained M270 1.6-litre petrol engines typically reach 120,000-150,000 miles. M282 1.3-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
• M282 (2019+): promising design but carbon build-up requires attention from 40k miles
• Regular oil changes every 10,000 miles significantly extends life

The 2013-2014 CLA 180 and CLA 200 with the M270 1.6-litre engine carry the highest risk due to timing chain tensioner failure. Post-2019 M282 1.3-litre units are significantly more reliable.

• 2013-2014 M270 (CLA 180/200): highest complaint rate for timing chain issues
• 2015-2019 M270: improved but still monitor for chain rattle
• 2019+ M282 (1.3L): fewer major failures; carbon build-up is the main concern
• Always check service history for regular oil changes

Timing chain replacement on a CLA 180/200 petrol costs £1,000-£1,500 at a specialist or £1,600-£2,200 at a main dealer. This is preventative work. If the chain has already slipped, full engine replacement at £2,500-£3,500 is required.

• Specialist preventative chain/tensioner replacement: £1,000-£1,500
• Dealer pricing for same work: £1,600-£2,200
• Rattling noise on cold start for 1-2 seconds is the early warning sign
• Once timing jumps, valves contact pistons - engine is beyond repair

Yes, if the car is otherwise sound. A CLA 180/200 petrol worth £6,000-£10,000 with a failed M270 engine justifies a £2,500-£3,500 rebuilt engine. For older, high-mileage petrol models, a used engine at £900-£1,800 is often the smarter financial choice.

• CLA 180/200 with good body/interior: replacement engine is cost-effective
• 120,000+ mile examples: consider used engine over rebuilt
• Specialist rebuilt engines fix original design weaknesses and include warranty
• Compare against £3,500-£4,500 main dealer new engine quotes

The CLA 180 and CLA 200 share the same engine family in each generation (M270 1.6L or M282 1.3L) - the difference is purely in engine mapping and power output. Reliability is identical between the two variants.

• Both CLA 180 and CLA 200 use the same M270/M282 engine hardware
• Power difference is electronic mapping, not mechanical differences
• Service history matters more than which variant you choose
