How much does a Mercedes Vito 109-119 CDI engine replacement cost in the UK?

A used Mercedes Vito engine typically costs between £900 and £2,500. A fully reconditioned unit costs £1,800 to £3,500 before labour, VAT, or ancillary components. A new OEM engine costs £2,500–£4,000+, with labour pushing the total above £5,000. Use our calculator for a figure specific to your van.

What are the common problems with the Mercedes Vito 109-119 CDI?

Timing chain stretch on the OM622 (109/111 CDI) — a critical weakness with repairs costing up to €4,000, timing chain stretch and guide wear on the OM651 from ~120,000 km, injector failures on both engines, EGR clogging and turbo issues on the OM651, and DPF/AdBlue system problems on modern Vito diesels.

Is it worth replacing a Mercedes Vito 109-119 CDI engine, or should I scrap the van?

Depends on vehicle value and condition. Against a well-kept £6,000–£15,000 Vito, a £2,500–£3,500 recon is 20–60% of the van's value. For a clean OM651-engined 114/116/119 CDI with full service history, replacement is often worth it. For OM622-engined 109/111 CDI vans, carefully evaluate the cost — these engines are problematic and you may be better off replacing the van.

How do I find my Mercedes Vito 109-119 CDI engine code?

Listed on the VIN plate and vehicle documentation. The Vito 109 CDI and 111 CDI use the OM622.951 (1.6L, 88–114 hp). The Vito 114 CDI, 116 CDI and 119 CDI use the OM651.950 (2.1L, 136–190 hp). Front-wheel-drive Vitos have the 1.6L engine; rear- and all-wheel-drive Vitos have the 2.1L engine. Tell us your registration date and we'll confirm it for free.

Can I repair the Vito timing chain, or does it need engine replacement?

Yes — if caught early. On both engines, a preventative chain replacement (£800–£2,000) is far cheaper than a catastrophic engine failure (£3,000–£5,500). At the first sign of cold-start rattle, book an inspection immediately. On the OM622 (109/111 CDI), timing chain wear is particularly common — some owners report failure before 150,000 km. Regular oil changes with the correct MB-spec oil are essential to minimise chain wear.

Common Problems

1. Timing Chain Stretch (OM622 — Renault 1.6 dCi)

Symptoms: Rattling noise on cold start, power loss, engine backfires, rough idling, check engine light

Typical mileage: 60,000–90,000 miles — premature wear before 150,000 km

Repair cost: £800–£2,000 (timing chain kit, tensioners and guides)

Replacement cost: £3,000–£5,500 (if chain snaps — full engine replacement)

🔴 Immediate - if you hear rattling on cold start, book an inspection today

Our recommendation:

The OM622 1.6-litre engine is the most problematic engine in the W447 Vito range. Timing chains can wear prematurely, requiring replacement before 150,000 km. Mercedes' decision to fit Renault-sourced engines in entry-level Vitos has resulted in significant reliability issues. Repair costs can reach €4,000 for a chain and injector replacement. At the first sign of cold-start rattling, get the chain inspected immediately. A £800–£2,000 preventative repair is dramatically cheaper than a £3,000–£5,500 engine replacement. If you're buying a Vito, avoid the 109 and 111 CDI models — they are considered a "version à éviter".

1. Timing Chain Stretch (OM622 — Renault 1.6 dCi)

Symptoms: Rattling noise on cold start, power loss, engine backfires, rough idling, check engine light

Typical mileage: 60,000–90,000 miles — premature wear before 150,000 km

Repair cost: £800–£2,000 (timing chain kit, tensioners and guides)

Replacement cost: £3,000–£5,500 (if chain snaps — full engine replacement)

🔴 Immediate - if you hear rattling on cold start, book an inspection today

Our recommendation:

Read the full timing chain failure guide

2. Timing Chain Stretch & Guide Wear (OM651 2.1L)

Symptoms: Rattling noise on cold start for 2–5 seconds, metallic noise from the front of the engine, misfires, cam/crank correlation fault codes, check engine light

Typical mileage: 75,000+ miles — can stretch from ~120,000 km

Repair cost: £800–£2,000 (chain kit, tensioners and guides)

Replacement cost: £3,000–£5,500 (if chain jumps — full engine replacement)

🔴 Immediate - if you hear rattling on cold start, book an inspection today

Our recommendation:

The OM651 2.1-litre engine is "fundamentally reliable" — 200,000–300,000 km examples are common. However, the timing chain is the single most critical failure point. If the chain stretches beyond tolerance or a guide fails, it can cause misfires and cam/crank correlation codes; if it jumps a tooth, catastrophic engine damage occurs. At the first sign of cold-start rattling, get the chain inspected immediately. A £800–£2,000 preventative repair is dramatically cheaper than a £3,000–£5,500 engine replacement.

3. Injector Failure (OM622 & OM651)

Symptoms: Rough idle, misfires, reluctance to start, injector leak-back, black smoke, engine warning light

Typical mileage: 60,000–120,000 miles

Repair cost: £400–£800 per injector

Replacement cost: N/A — repair only (does not progress to engine replacement if addressed)

🟠 Check - book inspection urgently if symptoms appear

Our recommendation:

Injector failures are a common issue across both Vito CDI engines. On the OM622, injectors are a key weakness. On the OM651, early Delphi injectors are known to fail. A common symptom is reluctance to start due to excessive injector leak-back. If you experience rough idle or starting problems, have the injectors tested. Catching this early prevents fuel system contamination and more serious engine damage.

Read the full injector failure guide

4. EGR Clogging & Turbo Issues (OM651)

Symptoms: Hesitation, rough idle, loss of power, limp mode, whistling from the engine bay, oil mist

Typical mileage: 60,000–120,000 miles

Repair cost: £300–£800 (EGR cleaning) / £1,000–£2,500 (turbocharger repair or replacement)

Replacement cost: £3,000–£5,500 (if ignored — full engine replacement)

🟡 Monitor - book inspection if symptoms develop

Our recommendation:

The OM651 engine suffers from EGR clogging due to soot buildup. Turbo issues including oil mist, whistle, low boost and lag are also documented. One owner reported a broken EGR pipe due to thermal stress and carbon buildup on a Vito OM651. If you experience hesitation, rough idle or power loss, have the EGR system inspected. Regular motorway driving can help mitigate carbon buildup. A £300–£800 repair is far cheaper than a £3,000–£5,500 engine replacement.

Read the full EGR failure guide

5. DPF & AdBlue System Issues (OM651)

Symptoms: DPF warning light, reduced performance, limp mode, AdBlue countdown warning, engine warning light

Typical mileage: Any mileage — short urban journeys accelerate the issue

Repair cost: £300–£800 (forced DPF regeneration) / £1,000–£2,500 (DPF or AdBlue system repair)

Replacement cost: N/A — repair only

🟠 Check - book inspection if warning appears

Our recommendation:

DPF and AdBlue system issues are common on modern Vito diesels. The DPF can become clogged if the van is used primarily for short urban trips. AdBlue system faults can be difficult to diagnose and expensive to fix. If a warning appears, book a forced regeneration or system inspection immediately — ignoring countdown warnings can prevent the vehicle from starting.

Buying This Vito 109-119 CDI? Check These First

Buy If

OM651-engined Vito (114, 116 or 119 CDI) — the 2.1-litre Mercedes diesel is fundamentally reliable
Full service history with regular oil changes using MB-approved oil
No cold-start rattling — this is a critical warning sign
Documented timing chain and injector work on higher-mileage examples
Evidence of regular motorway driving (DPF health)

Avoid If

OM622-engined Vito (109 or 111 CDI) — these are the problematic Renault-sourced engines
Cold-start rattle with no documented timing chain history
Poor service history — the OM651 is reliable but needs proper maintenance
DPF, AdBlue or check engine warnings — emissions system repairs can be costly

Closing Verdict

The Vito 109-119 CDI badge spans two very different engine generations. The OM622 (109 and 111 CDI) is a Renault-sourced 1.6-litre diesel that is widely considered unreliable — owners report timing chain wear before 150,000 km and injector failures with repair costs up to €4,000. Avoid the 109 and 111 CDI models — they are a "version à éviter". The OM651 (114, 116 and 119 CDI) is a robust and proven 2.1-litre Mercedes diesel — "fundamentally reliable" with many 200,000–300,000 km examples. Buy a 114, 116 or 119 CDI with full service history. Buy on documented history, not on price alone.

Buying Checklist

Before you buy a used Mercedes Vito 109-119 CDI (or before you commit to an engine replacement), check these:

Engine Type — Check the badge: 109 and 111 CDI use the problematic OM622 (Renault 1.6L); 114, 116 and 119 CDI use the robust OM651 (Mercedes 2.1L)

Cold Start — Listen for rattling or ticking from the engine (timing chain warning — this is critical)

Injector Health — Any rough idle, reluctance to start, or misfires? (Injector leak-back)

Service History — Including which engine (OM622 or OM651) and confirmed oil-interval discipline

DPF & AdBlue — Check for warning lights; short journeys are a red flag

Turbo Health — Listen for whistling; check for power loss or oil mist

Engine Warning Light — Have codes been read? Look for timing, injector or emission-related codes

MOT History — Check for emissions-related failures
