Nissan Qashqai: 1.2 DIG-T Timing Chain Guide Disintegration

The HRA2DDT 1.2-litre turbocharged engine (marketed as DIG-T) uses plastic timing chain guides that are undersized for the sustained heat cycling of a turbocharged application. The guides crack and shed fragments into the oil sump from as low as 60,000 km, and once the guide fails the timing chain loses lateral support and can derail, jump timing, or snap entirely. This is a terminal failure mode that typically destroys the cylinder head and sometimes the block, as piston-to-valve contact occurs at high speed.

• Rattling or slapping noise from the front of the engine, worse on cold start but sometimes persistent when warm
• Plastic debris visible in drained oil or caught in cut-open oil filter element
• Check engine light with camshaft/crankshaft correlation codes (P0016, P0017)
• Sudden catastrophic engine noise followed by loss of power — chain derailment event
• Engine stall at speed with no warning, not restarting

1. 1

   Cold-start and listen carefully for any chain rattle or ticking from the front of the engine.

2. 2

   Check the oil filter cut-open for plastic debris fragments.

3. 3

   Request a Nissan dealer scan for camshaft correlation faults.

4. 4

   Verify whether Nissan's extended goodwill warranty for this issue has been applied, and inspect the service history for proactive chain/guide replacement.

Parts involved: Timing chain.

$2,500 to $14,000 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.

• “Has the timing chain, tensioner, and guides been replaced preventatively, and can you provide the dealer invoice?”
• “Was this vehicle inspected under any Nissan goodwill programme for the 1.2 DIG-T timing chain issue?”
• “Has the engine ever been replaced or rebuilt — if so, what was the documented reason?”

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.
