Common Failure
The M260 engine has a known cylinder head defect affecting exhaust valve seats - particularly on 2019-2022 models. Mercedes has issued an extended warranty (15 years / 150,000 miles) covering this specific issue. Other reported issues include CAMTRONIC system failures, timing chain tensioner wear, and oil consumption.
The Mercedes-AMG GLA 35's M260 engine delivers impressive performance but has developed a well-documented reputation for specific, potentially serious failures. The cylinder head defect - affecting exhaust valve seats - is the most significant concern, with some owners requiring replacement at as little as 11,000 miles. Timing chain tensioner wear, CAMTRONIC system failures, and oil consumption also feature prominently. Every rebuilt engine supplied through EnginesMarket includes upgraded components designed to address the original failure point - plus a minimum 12-month unlimited mileage warranty. Below we break down the most common AMG GLA 35 engine failures, what they cost to fix, and when replacement is the smarter financial decision.

Vehicle Value Check
Vehicle Value Check
A typical AMG GLA 35 is worth £30,000-£50,000 depending on age and mileage - the full replacement cost of £4,500-£7,800 is modest relative to vehicle value. Given the known cylinder head defect, many cars may qualify for Mercedes extended warranty coverage (15 years / 150,000 miles) - always check with your dealer before authorising any repair.
Our Recommendation
Our Recommendation
The M260 cylinder head issue is serious and can appear with minimal warning. If your AMG GLA 35 experiences misfires, rough running, or loss of power, have the cylinder head inspected immediately. Given that Mercedes has issued an extended warranty for this specific issue, contact your dealer first to determine if your vehicle is covered. If out of warranty, specialist cylinder head replacement at £2,500-£3,800 is significantly better value than dealer pricing.

Mercedes Benz AMG GLA 35 Engine ReplacementFrequently Asked Questions
Question 1How much does it cost to replace an AMG GLA 35 engine in the UK-
An AMG GLA 35 engine replacement typically costs between £3,500 and £7,800 depending on condition type and whether fitting is included. M260 2.0-litre turbo units range from £3,500 to £7,800 supply only.
- Rebuilt M260 (AMG GLA 35): £3,500-£7,800 supply only
- Reconditioned units: £3,800-£5,800
- Used engines from breakers: £2,200-£4,000 but higher risk
- Labour for supply & fit adds £1,000-£1,800 to any engine price
Question 2Is the M260 engine in the AMG GLA 35 reliable-
The M260 is a high-performance engine that delivers impressive power, but it has several well-documented issues that owners should be aware of. Post-facelift (2023+) M260 engines with 48V MHEV appear more reliable.
- Cylinder head / valve seat defect - extended warranty covers many 2019-2022 models
- Timing chain tensioner wear causing cold-start rattle
- CAMTRONIC system failures (expensive to repair)
- Turbocharger wear and oil consumption
- Regular oil changes every 5,000-7,000 miles are critical for longevity
Question 3What are the signs of M260 cylinder head failure in an AMG GLA 35-
The M260 cylinder head defect typically manifests as valve seat wear - symptoms can appear with minimal warning.
- Engine misfires or rough running
- Loss of power and poor acceleration
- Check engine light illuminated
- Rough idle, particularly when warm
- Some owners have reported failure as early as 11,000 miles
Question 4Should I repair or replace my AMG GLA 35 engine-
Repair if the failure is isolated (e.g., timing chain tensioner, turbocharger). Replace if there's bottom end damage, bore scoring, or catastrophic cylinder head failure.
- Timing chain tensioner replacement: £450-£750 - do this at first sign of rattle
- Cylinder head replacement: £2,500-£3,800 - for valve seat wear without piston damage
- Full M260 rebuild: £4,500-£7,800 - for catastrophic failure or 80k+ miles
- Given AMG GLA 35 values (£30,000-£50,000), a rebuilt engine is typically good value
Question 5How do I know which engine code my AMG GLA 35 has-
Check your vehicle log book (V5C) for the engine number, which includes the engine code prefix.
- V5C log book shows full engine number with code prefix
- Engine code stamped on cylinder block
- AMG GLA 35 (2020-present): M260.920 (2.0L turbo, 306hp)
- Service history documents list engine type
Question 6Can I fit a used AMG GLA 35 engine myself-
We strongly advise against DIY fitting on an AMG GLA 35. The transverse-mounted engine layout, 8-speed DCT gearbox alignment, and ECU coding requirements demand specialist equipment and expertise.
- Transverse engine mounting requires specialist alignment
- 8G-DCT transmission alignment needs precise setup
- ECU coding and immobiliser synchronisation required
- AMG-specific calibration and adaptations needed
- Specialist supply & fit costs £1,000-£1,800 - essential for an AMG
Question 7What warranty comes with a reconditioned AMG GLA 35 engine-
Every engine supplied through EnginesMarket carries a minimum 12-month unlimited mileage warranty, with many specialists offering 24-month coverage on M260 rebuilds. This includes parts and labour for any manufacturing defect or installation error.
- 12-month unlimited mileage is the minimum standard
- M260 rebuilds often include 24-month warranty
- All warranties cover parts, labour, and MOT compliance
- Extended warranties available at point of purchase
