How much does a Mercedes V167 engine replacement cost in the UK?

A reconditioned V167 engine typically costs £2,500–£15,000 supply only [MB‑QUOTE], depending on engine — the OM654 four‑cylinder diesel runs £2,500–£4,500, while the M177 V8 in the GLE 63 AMG can cost £8,000–£15,000. Fitting adds £780–£1,430. Use our calculator for a personalised quote.

Which Mercedes V167 engine is the most reliable?

The M256 3.0‑litre six‑cylinder petrol with EQ Boost (GLE 450) is the most advanced and generally reliable choice — it's smooth, responsive, and benefits from the mild‑hybrid system. The OM656 six‑cylinder diesel is robust but suffers from oil‑cooler seal leaks; the OM654 four‑cylinder diesel is economical but needs chain monitoring.

What are the common problems with the Mercedes V167?

OM654 diesels suffer timing‑chain stretch; OM656 diesels have oil‑cooler seal leaks; M256 EQ Boost engines can experience ISG (integrated starter‑generator) failure; M176/M177 V8 petrols can develop turbo coolant line failures. A recall (22V‑614) affects the M256 ISG. Regular servicing is critical across all engines.

Is the Mercedes V167 reliable?

It depends on the engine. The M256 is generally excellent but watch for ISG issues. The OM656 diesel is robust but has a well‑documented oil‑cooler seal weakness. The OM654 needs chain monitoring. The M176/M177 are high‑performance engines that demand meticulous maintenance. Overall, a well‑maintained V167 can be a dependable luxury SUV.

Which Mercedes V167 engine should I avoid?

No engine is an outright "avoid" — but an OM654 without documented timing‑chain replacement is one we'd approach with caution. Similarly, a high‑mileage GLE 63 AMG without full service history warrants careful inspection. Always get a specialist pre‑purchase inspection.

How do I know if my V167 engine needs replacing?

Key warning signs include: cold‑start rattle (OM654 chain), burning oil smell (OM656 seals), warning lights relating to the 48‑volt system (M256 ISG), coolant loss with no visible leak (M176/M177 coolant lines), or a top‑end tick that worsens (M177 lifters). If you experience any of these, get a diagnosis immediately — early intervention saves thousands.

Is it worth replacing a Mercedes V167 engine, or should I scrap the car?

Depends on the car's value. Against a well‑kept £35,000 V167, a £5,500 OM656 recon is 16% of the car's value — safe if the car is otherwise sound. Against a tired £18,000 example, the same recon is 31% — still safe but approaching our 70% Mercedes threshold. Use our 70% rule as your guide.

How long do Mercedes V167 engines last?

With proper maintenance, the M256 petrol can exceed 150,000 miles, and the OM656 diesel can reach 200,000+ miles with regular oil changes. The OM654 diesel is also capable of high mileage but requires chain monitoring. The M176/M177 V8s are durable but demand expensive preventative maintenance.

What is the difference between the V167 and C167?

Both share the same platform and engines. The V167 is the 5‑door SUV (2019–2023, this page), while the C167 is the SUV coupé (2019–2023). Costs vary slightly by body style due to labour access — see the C167's own Generation Page for specifics.

How do I find my Mercedes V167 engine code?

Listed on the VIN plate (visible through the windscreen) and in the vehicle documentation. The code is stamped on the engine block — on OM654/OM656 it's on the front left, on M256/M176/M177 it's on the right side. Tell us your variant and registration year, and we'll identify it for you.

The V167 rule

A £4,000–£7,000 M256 recon against a £20,000–£50,000 V167 sits at 8–35% of the car’s value — generally safe. Against a sub‑£20,000 example, the same recon can brush our 70% Mercedes threshold — we’ll honestly tell you to walk away. Against a well‑kept £40,000+ example, the same recon drops to a routine 10–18% — a straightforward repair decision. Value the car first.

OM654 2.0 diesel — cheapest recon and simple repairs.
Which V167 Costs Most To Own?

Common Problems

01

OM654

Timing‑Chain Stretch

Affected models:

V167 GLE 300 d, GLE 350 de (OM654 diesel).

Typical failure mileage:

60,000–100,000 miles.

Root cause:

The OM654 has a rear‑mounted timing chain that can stretch over time. Cold‑start rattle is the classic early warning — if ignored, the chain can jump and cause catastrophic engine damage.

Catastrophic (Replacement)

Our Recommendation

At the first sign of cold‑start rattle on an OM654, get the chain inspected immediately — a £600–£1,500 preventative repair is far cheaper than the £2,500+ replacement that follows if ignored.

02

M256

ISG (Integrated Starter‑Generator) Failure

Affected models:

V167 GLE 450, AMG GLE 53 (M256 EQ Boost petrol).

M256 ISG (Integrated Starter‑Generator) Failure

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The integrated starter‑generator (ISG) in the M256 EQ Boost system can fail, leading to loss of the 48‑volt mild‑hybrid functionality, warning lights, and potential drivability issues. A recall (22V‑614) affects the entire W167 GLE range.

Our Recommendation

If you own an M256‑powered V167, check if the ISG recall (22V‑614) has been performed. A £1,000–£2,500 repair is cheaper than the £4,000+ replacement that follows a full failure.

03

M176

/ M177 Turbo Coolant Line Failure

Affected models:

V167 GLE 580, GLE 63 AMG, GLE 63 S AMG (M176/M177 V8).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The hot‑vee design places the turbos in the V of the engine, and the coolant lines can degrade with heat cycling, leading to coolant loss and potential turbo damage.

Our Recommendation

If you own a V8‑powered V167, have the coolant system inspected annually — a £1,000–£2,500 repair is far cheaper than the £6,000+ replacement that follows a catastrophic failure.

Compare M176 / M177 engine prices for your V167

04

OM656

Oil‑Cooler Seal Leak

Affected models:

V167 GLE 350 d, GLE 400 d (OM656 six‑cylinder diesel).

Typical failure mileage:

80,000–150,000 miles.

Root cause:

The oil‑cooler O‑rings in the V of the OM656 engine can degrade with heat cycling, causing oil leaks that can drip onto the exhaust and create a burning smell. Labour is intensive as the intake manifold must be removed.

Our Recommendation

If you notice a burning oil smell or oil residue in the engine V, have the oil‑cooler seals replaced immediately — an £800–£1,500 repair is cheaper than the £3,500+ replacement that follows if the engine runs low on oil.
