Ford Transit Custom: 2.0 EcoBlue wet timing belt (belt-in-oil) — premature failure, interval cut to 6yr/160,000km

2.0 EcoBlue wet timing belt (belt-in-oil) — premature failure, interval cut to 6yr/160,000km is a common engine fault on the Ford Transit Custom on the 2016–2023 cars, and we rate it critical. Putting it right costs $2,000 to $12,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 7 documented faults on the Ford Transit Custom.

What you are looking at

No photograph available

We do not hold a verified photograph of the Timing belt yet. We would rather show none than show a picture of a different part.

What goes wrong

From late 2016 the Custom switched to the 2.0 EcoBlue, which runs its cam belt in engine oil. Failed or frequent DPF regenerations dilute the oil with diesel, the diluted oil attacks the belt, and belts have let go at 50,000-70,000 km — well inside Ford's original 10-year/240,000 km claim, which Ford has since cut to 6 years/160,000 km. Belt debris can also block the oil pick-up and starve the engine. Failure means valve/piston contact and effectively an engine. Note this is the EcoBlue only — the earlier 2.2 is chain-driven.

What you would notice

  • Low oil pressure warning light
  • Rattle from the front of the engine
  • Rubber particles in drained oil or the filter housing
  • Sudden engine stoppage with no prior symptoms

How to check it

Where to look. Inside the front of the engine — belt runs in oil, cannot be visually checked

Service history is everything: correct low-ash oil at short intervals, and on any van over 6 years or 100,000 km, an invoice for the wet belt job (belt, tensioner, oil pump belt where applicable). Ask about the van's duty cycle — short urban runs mean constant DPF regens and the shortest belt life. No belt invoice on a 2016-2019 van = negotiate the full job off the price.

Parts involved: Timing belt.

What it costs to put right

$2,000 to $12,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Has the wet timing belt been done, with an invoice?”
  • “What oil and intervals were used?”
  • “Mostly urban or open-road use?”

Now check the Ford Transit Custom you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Ford Transit Custom buyer questions

Is 2.0 ecoblue wet timing belt (belt-in-oil) — premature failure, interval cut to 6yr/160,000km serious on a Ford Transit Custom?

We rate it critical and common on the Ford Transit Custom. From late 2016 the Custom switched to the 2.0 EcoBlue, which runs its cam belt in engine oil. Failed or frequent DPF regenerations dilute the oil with diesel, the diluted oil attacks the belt, and belts have let go at 50,000-70,000 km — well inside Ford's original 10-year/240,000 km claim, which Ford has since cut to 6 years/160,000 km. Belt debris can also block the oil pick-up and starve the engine. Failure means valve/piston contact and effectively an engine. Note this is the EcoBlue only — the earlier 2.2 is chain-driven.

How much does it cost to fix on a Ford Transit Custom?

$2,000 to $12,000 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Ford Transit Custom years are affected?

Our research records this fault on the 2016–2023 Ford Transit Custom. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Service history is everything: correct low-ash oil at short intervals, and on any van over 6 years or 100,000 km, an invoice for the wet belt job (belt, tensioner, oil pump belt where applicable). Ask about the van's duty cycle — short urban runs mean constant DPF regens and the shortest belt life. No belt invoice on a 2016-2019 van = negotiate the full job off the price.
