Nissan Juke: MR16DDT Intercooler and Boost Hose Failure

MR16DDT Intercooler and Boost Hose Failure is a common engine fault on the Nissan Juke on the 2010–2020 cars, and we rate it major. Putting it right costs $150 to $700 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 21 documented faults on the Nissan Juke.

What you are looking at

No photograph available

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

What goes wrong

The intercooler pipe routing on the MR16DDT turbo engine uses silicone and moulded plastic hose sections secured by clips. These boost hoses are subjected to significant pressure cycling and heat soak in the confined engine bay of the Juke. The clips loosen over time or the silicone sections split, causing a sudden partial or total loss of boost pressure. In some cases an unsecured hose can allow unmetered air into the intake post-MAF, causing rough running and rich fuelling that accelerates engine wear. A secondary issue is the intercooler end-tank plastic cracking on high-mileage examples.

What you would notice

  • Hissing or whooshing noise from the engine bay under boost
  • Sudden flat spot or loss of power under hard acceleration
  • Rough idle or rich fuel smell after a hard run
  • Boost gauge (if fitted) fails to reach normal pressure
  • MAF sensor fault codes stored (P0101, P0102) due to unmetered air

How to check it

Where to look. Intercooler to throttle body boost pipe, top front of engine bay; also intercooler-to-turbo lower hose

With the engine cold, squeeze all rubber/silicone hose sections in the intake tract for cracks or splits. Check all hose-clip positions for proper seating — a loose clip will be finger-tight rather than firm. During a test drive, apply full throttle briefly and check for a hissing sound or sudden loss of power that recovers when lifting off. Inspect the intercooler end-tanks for hairline cracks.

Parts involved: Turbocharger.

What it costs to put right

$150 to $700 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

  • “Have any intake or boost hoses been replaced, or has the car ever been diagnosed with a boost leak?”
  • “Has the car ever exhibited a sudden power loss under hard acceleration?”

Now check the Nissan Juke 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.

Nissan Juke buyer questions

Is mr16ddt intercooler and boost hose failure serious on a Nissan Juke?

We rate it major and common on the Nissan Juke. The intercooler pipe routing on the MR16DDT turbo engine uses silicone and moulded plastic hose sections secured by clips. These boost hoses are subjected to significant pressure cycling and heat soak in the confined engine bay of the Juke. The clips loosen over time or the silicone sections split, causing a sudden partial or total loss of boost pressure. In some cases an unsecured hose can allow unmetered air into the intake post-MAF, causing rough running and rich fuelling that accelerates engine wear. A secondary issue is the intercooler end-tank plastic cracking on high-mileage examples.

How much does it cost to fix on a Nissan Juke?

$150 to $700 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 Nissan Juke years are affected?

Our research records this fault on the 2010–2020 Nissan Juke. 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?

With the engine cold, squeeze all rubber/silicone hose sections in the intake tract for cracks or splits. Check all hose-clip positions for proper seating — a loose clip will be finger-tight rather than firm. During a test drive, apply full throttle briefly and check for a hissing sound or sudden loss of power that recovers when lifting off. Inspect the intercooler end-tanks for hairline cracks.
