Common Failure
The OM651.940 suffers from timing chain tensioner seal failure causing cold-start rattle. Injector seal blow-by and EGR cooler cracking are also common on higher-mileage examples.
The Mercedes Vito 109-119 CDI range relies on the OM651 2.1-litre diesel - a robust commercial workhorse that has developed a well-documented reputation for specific, predictable failures. Timing chain tensioner seal failure (REC-005099) dominates replacement demand, while injector seal blow-by and EGR cooler cracking also drive significant repair enquiries. 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 Vito 109-119 CDI engine failures, what they cost to fix, and when replacement is the smarter financial decision.
Why the Vito 109-119 CDI Rattles on Cold Start
Affected Vehicles
Mercedes Vito 109 CDI, 110 CDI, 113 CDI, 116 CDI, 119 CDI (2010-2024, OM651.940, OM651.955, OM651.958)
Typical Failure Mileage
70,000 - 120,000 miles
Root Cause
The OM651 timing chain is located at the rear of the engine block. A faulty tensioner seal (REC-005099 recall) allows oil pressure loss, causing chain slack and a characteristic rattle on cold start. The chain stretches and guides wear over time. If ignored, the chain can jump teeth, leading to catastrophic valve and piston interference.

Vehicle Value Check
Vehicle Value Check
A typical W639 or W447 Vito 109-119 CDI is worth £4,000-£15,000 depending on age and mileage - the full replacement cost of £2,500-£4,200 is modest relative to vehicle value for most examples. For vehicles worth under £4,000, evaluate repair options carefully.
Our Recommendation
Our Recommendation
We recommend replacing the chain assembly only if cold-start rattle is recent and cylinder compression remains stable. On a Vito with confirmed chain jump, metallic knocking, or diagnostic timing deviation codes, a rebuilt OM651 is the only economically sound choice given the extensive labour required for engine-out diagnostics and the high risk of repeat failure with stock components.

Mercedes Vito 109-119 CDI Engine ReplacementFrequently Asked Questions
Question 1How much does a Mercedes Vito 109-119 CDI engine replacement cost in the UK-
A Vito 109-119 CDI engine replacement typically costs between £1,500 and £4,500 depending on engine code (OM651.940, OM651.955 or OM651.958), condition type, and whether fitting is included.
- Rebuilt OM651.940 (109-113 CDI): £1,500-£3,300 supply only
- Rebuilt OM651.955 (116-119 CDI): £1,800-£4,200 supply only
- Used engines from breakers: £800-£2,500 but higher risk
- Labour for supply & fit adds £800-£1,200 to any engine price
Question 2What causes the OM651 timing chain rattle on cold start in a Vito 109-119 CDI-
The OM651 timing chain rattle is caused by tensioner seal failure allowing oil pressure loss, leading to chain stretch and guide wear.
- The chain is at the rear of the engine - most repairs require engine removal
- REC-005099 recall addresses tensioner seal leaks on 2014 Vito models
- Cold-start rattling indicates chain elongation requiring full engine-out replacement
- Rebuilt OM651 units include updated tensioner seals and hardened guide rails as standard
Question 3What are the signs of injector seal failure on a Vito 109-119 CDI-
The OM651's injector seals typically show warning signs before complete failure.
- Loss of power and rough idle
- Diesel pooling in the valve cover around injectors
- Increased oil consumption and sludge buildup
- Check engine light with rail pressure error codes
- Hard starting when warm
Question 4Should I repair or replace my Vito 109-119 CDI engine-
Repair if the failure is isolated (e.g., timing chain tensioner on OM651, injector seals, EGR cooler, AdBlue injector). Replace if there's bottom end damage, bore scoring, or catastrophic timing chain failure.
- OM651 timing chain replacement: £1,200-£1,800 - do this if rattle is persistent
- Injector seal & EGR replacement: £800-£1,400 - catch it early
- Full OM651 rebuild: £2,500-£4,200 - for catastrophic failure or 120k+ miles
- Given Vito 109-119 CDI values (£4,000-£15,000), a rebuilt engine is typically good value
Question 5How do I know which engine code my Vito 109-119 CDI 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
- Vito 109 CDI: OM651.940 (95hp)
- Vito 110 CDI: OM651.940 (95hp)
- Vito 113 CDI: OM651.940 (136hp)
- Vito 116 CDI: OM651.955 (163hp)
- Vito 119 CDI: OM651.955 or OM651.958 (190hp)
Question 6Can I fit a used Vito 109-119 CDI engine myself-
We strongly advise against DIY fitting on a Vito 109-119 CDI. The OM651's rear-mounted timing chain and ECU coding requirements demand specialist equipment and expertise.
- Engine must be removed to access rear timing chain - requires proper lifting equipment
- Subframe must be lowered on W447 models - not a driveway job
- ECU coding and injector calibration require Mercedes-Benz Star Diagnosis tools
- Specialist supply & fit costs £800-£1,200 - worth every penny
Question 7What warranty comes with a reconditioned Vito 109-119 CDI engine-
Every engine supplied through EnginesMarket carries a minimum 12-month unlimited mileage warranty, with many specialists offering 24-month coverage on OM651 rebuilds. This includes parts and labour for any manufacturing defect or installation error.
- 12-month unlimited mileage is the minimum standard
- OM651 rebuilds often include 24-month warranty
- All warranties cover parts, labour, and MOT compliance
- Extended warranties available at point of purchase
