Other Faults on This Variant

Timing Chain Rattle and Tensioner Failure

Critical

2012-201560,000–120,000 miles£800–£1500

The 1.6 CDTi A16DTH/DTJ engine is notorious for timing chain noise and failure, often from as low as 60,000 miles. This is the most serious known fault on the Astra J diesel.

DPF Blockage and Regeneration System Failure

Severe

2012-201540,000–90,000 miles£200–£1000

DPF blockage is extremely common on the Astra J 1.6 CDTi. The engine's tendency to get stuck in failed regen cycles results in diesel contaminating the engine oil — a serious secondary issue.

EGR Cooler Failure and Intake Contamination

Severe

2012-201570,000–130,000 miles£500–£800

EGR cooler failure on the Astra J 1.6 CDTi causes coolant loss and in severe cases, coolant enters the intake manifold. This is a more serious failure than a simple EGR valve block.
