- Basic refinement levels
Engine #3 overview
The 1.5 TDCi 100 PS represents the sweet spot in Ford’s diesel range, offering balanced performance and economy. This turbocharged four-cylinder unit features variable geometry turbocharging and advanced exhaust gas recirculation for emissions compliance.
This turbocharged diesel employs a variable geometry turbocharger (VGT) combined with cooled EGR and selective catalytic reduction. The engine utilises AdBlue injection for NOx reduction and features a diesel particulate filter for emissions control.
Pros
- Excellent torque delivery
- Superior fuel economy
- Good all-round performance
- Proven reliability record
- Suitable for mixed driving conditions
Cons
- DPF requires regular regeneration
- AdBlue consumption adds running costs
- Complex emissions system
- Not ideal for short urban trips only
Engine #4 overview
The flagship 1.5 TDCi 120 PS delivers maximum performance in the Transit Connect range, featuring enhanced turbocharging and optimised fuel injection mapping. This top-specification diesel provides strong acceleration and excellent overtaking ability whilst maintaining respectable economy figures.
Built on the same foundation as the 100 PS variant, this enhanced version features a larger variable geometry turbocharger and revised ECU mapping. The engine maintains the same emissions control systems including particulate filter and AdBlue injection.
Pros
- Strong performance across the rev range
- Excellent for highway driving
- Good fuel economy for power level
- Refined operation
- Handles heavy loads confidently
Cons
- Higher initial cost
- More complex turbocharger system
- Requires quality engine oil for longevity
- DPF system requires careful maintenance
Maintenance cost
| Engine | Recommended Interval | Estimated Cost | Cost per 10,000 miles |
|---|---|---|---|
| 1.0 EcoBoost | 12,500 miles | £220-280 | £176-224 |
| 1.5 TDCi (75 PS) | 20,000 miles | £180-240 | £90-120 |
| 1.5 TDCi (100 PS) | 20,000 miles | £200-260 | £100-130 |
| 1.5 TDCi (120 PS) | 20,000 miles | £220-280 | £110-140 |
According to our Autopartspro mechanics, regular oil filter changes are crucial for turbocharged engines, especially the EcoBoost petrol unit which operates under high stress conditions.
Engine sound and character
The 1.0 EcoBoost produces a distinctive three-cylinder thrum that’s more noticeable at idle but smooths out under acceleration. Our specialists note that whilst initially unfamiliar to some drivers, this characteristic sound becomes less apparent once underway.
The 75 PS TDCi delivers a traditional diesel character with a purposeful rumble at low speeds. The more powerful TDCi variants benefit from better sound insulation and produce a more refined note, particularly the 120 PS version which maintains quieter operation even under full acceleration.
All diesel engines exhibit typical compression ignition characteristics, with cold start noise being most pronounced during winter months. The engine mount design effectively isolates vibration from the cabin across all variants.
Professional tip from our workshop: The EcoBoost requires a specific spark plug specification – never substitute with standard plugs as this can cause misfiring and catalyst damage.
