Hmm, been looking into the Ford vans, not at all keen on the Wet belt, asked Google and it may be okay but you certainly need to do the maintencance.
The
Ford 2.0L EcoBlue "wet belt" system, found in 3.5-tonne Transits since 2016, is a highly controversial design where the timing belt is submerged in engine oil. While designed to reduce noise and friction, real-world performance has led to significant reliability concerns across Europe.

Primary Problems and Risks
The biggest weakness of this system is
belt degradation caused by oil contamination.

- Oil Dilution: Failed DPF (Diesel Particulate Filter) regenerations can cause unburnt diesel to enter the oil, which chemically attacks the rubber compounds in the belt.
- Oil Pump Blockage: As the belt breaks down, it sheds rubber fibres and debris into the oil sump. This debris clogs the oil pick-up strainer, starving the engine of lubrication and leading to catastrophic failure or seizure.
- Sudden Failure: Experts warn that there is often no gradual deterioration or noise before the belt fails; it can be fine one minute and snap the next.

Early Warning Signs
If you own or are looking at an EcoBlue Transit, watch for these symptoms:
- Low Oil Pressure Light: The most critical sign that the oil strainer is already becoming blocked.
- Unusual Noises: Ticking, whining, or rattling sounds, especially on cold starts or during acceleration.
- Performance Issues: Rough idling, misfires, or a sudden loss of power during acceleration.
- Debris in Oil: Finding black rubber specks or "glop" during an oil change is a clear indicator of belt disintegration.

Revised Maintenance Requirements
Due to these issues, Ford UK officially lowered the replacement interval in 2024.

- Official Interval: Now 6 years or 100,000 miles (whichever comes first), down from the original 10 years/150,000 miles.
- Specialist Recommendation: Many independent garages advise replacement even earlier, around 60,000 to 80,000 miles, particularly for vans used for short urban trips or motorhomes that sit idle for long periods.
- Critical Oil Spec: You must use Ford-approved low-ash oil (WSS-M2C952-A1 0W-30). Using the wrong oil or skipping services drastically accelerates belt failure.

Replacement and Repair Costs
A wet belt replacement is a complex, multi-day job because it is located deep inside the engine.

- Preventative Replacement: Typically costs between £900 and £1,600 depending on the specific model (FWD vs RWD) and whether the oil pump belt and strainer are also replaced.
- Full Engine Failure: If the belt snaps, a new genuine engine can cost in excess of £10,000 plus several weeks of labour.

Is there a recall or a permanent fix for it?
There is
no official mass recall or a single "permanent fix" (such as a chain conversion) for the
Ford 2.0L EcoBlue wet belt system
as of early 2026.
Bristol Caravans and Motorhomes +1
Instead, Ford has addressed the issue by
significantly shortening the service intervals and updating their maintenance guidance to prevent failures.
Fleet News +1
Current Status of the "Fix"
- Revised Intervals: In 2024, Ford reduced the official replacement interval for the 2.0L EcoBlue timing belt to 6 years or 100,000 miles (down from 10 years or 150,000 miles).
- No Chain Conversion: Unlike the older 1.8L TDCi engines, there is currently no direct conversion kit to switch the 2.0L EcoBlue from a wet belt to a timing chain. The engine's internal architecture was designed specifically for a belt-in-oil system.
- Partial Recall History: While a specific recall was issued for some 2017 Transit Customs related to timing belts, there has been no universal recall for all EcoBlue engines. Repairs for premature failure are often handled on a case-by-case "goodwill" basis by Ford dealers, typically requiring a full service history.

Best Preventative Strategy
Since there is no "fit and forget" mechanical fix, owners must rely on strict maintenance:
- Frequent Oil Changes: Reducing oil change intervals to every 6,000–10,000 miles helps prevent fuel dilution, which is the primary cause of belt degradation.
- Oil Specification: Use only the Ford-approved WSS-M2C952-A1 (0W-30) oil. Incorrect oil grades can cause the belt to swell or delaminate rapidly.
- Proactive Replacement: Many independent specialists recommend replacing the belt at 5 years or 60,000–80,000 miles as a safety margin.
- Sump Inspection: When changing oil, experts suggest checking the oil pump strainer for any black rubber debris, which is a "canary in the coal mine" for belt failure.
I can banish her down there if I want to do important stuff in the back like annoy people on here or plot world domination. Stuff like that.
. As Okta above says, probably more commercial reasons for changing to Aisin. ZF have an extremely good reputation, being used in numerous high end vehicles.
