Nissan Juke: MR16DDT 1.6T Timing Chain Stretch and Tensioner Failure

The MR16DDT turbocharged 1.6-litre engine used in AWD Juke models shares its timing chain assembly with the Qashqai and X-Trail. The plastic-tipped chain tensioner wears prematurely, allowing chain slack. Oil contamination from carbon buildup accelerates guide wear. If ignored, chain skip can cause bent valves and engine write-off. Documented extensively across NZ/AU Juke forums and UK owners clubs as the most serious mechanical fault on this platform.

• Rattling or slapping noise on cold startup from front of engine
• Noise fades after warm-up but returns on cold starts
• Check engine light with camshaft position or timing codes
• Rough idle or hunting on startup
• Timing warning lamp illuminated

1. 1

   Start cold and listen for chain rattle from the front right of the engine for the first 30 seconds.

2. 2

   Check oil service history — extended intervals dramatically worsen chain wear.

3. 3

   Scan for P0011, P0021 or timing-related codes.

4. 4

   Ask for evidence of chain and tensioner replacement.

Parts involved: Timing chain.

$2,200 to $5,500 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.

• “Has the timing chain and tensioner been replaced, and do you have receipts?”
• “Has oil been changed every 5,000–7,500 km with the correct 0W-20 or 5W-30 spec?”
• “Has a mechanic inspected for chain rattle on cold start?”

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.
