How much does an M260/M264 engine replacement cost?

A reconditioned M260/M264 typically costs £4,500–£7,500 supply only [MB‑QUOTE], varying by displacement (1.5L vs 2.0L) and variant. Fitting adds £650–£1,300 depending on labour rates.

Is the M260/M264 a reliable engine?

The M260/M264 are considered reasonably reliable in early production, earning 3.0★ out of 5 [MB‑VERIFIED] — but well-documented cylinder head failures and timing chain issues mean diligent maintenance is essential.

What is the most common M260/M264 failure?

Cylinder head failure — specifically exhaust valve seat wear leading to misfires and compression loss — typically appears between 40,000–120,000 miles. Mercedes issued extended warranties for the M260 in some markets.

Which Mercedes models use the M260/M264?

The M260 (transverse) powers A‑Class, B‑Class, CLA, GLA, and GLB. The M264 (longitudinal) powers C‑Class, E‑Class, CLS, GLC, and G‑Class — the key difference is engine orientation.

How long does the M260/M264 last?

With meticulous maintenance, 160,000–190,000 miles is achievable — but high‑mileage examples often require significant expenditure on cylinder head or timing chain work. The 48V mild-hybrid system can also introduce additional complexity.

Verdict & Rating

Rating:

3

out of 5

85% confidence – based on cross-referenced specialist reports, owner forums, and documented warranty extensions; proprietary enquiry data pending full verification.

The M260/M264 are refined, efficient modern fours – but cylinder head and timing chain failures are well-documented and expensive to fix – buy only with full service history and warranty cover.

Best for:

Drivers who want a modern, efficient Mercedes with the latest technology and are prepared for specialist maintenance.

Avoid if:

You need bulletproof, low-maintenance reliability on a tight budget – older <a href='https://mercedesengines.uk/engine/m274'>M274</a>/M270 engines are simpler and more proven.
