Engine / equipment: 1.4 Turbo A14NET (Astra J, Meriva B, Mokka, Zafira C, Cascada…)
Period mentioned: 2009–2018
Symptoms: Chain rattle, engine light and lack of power. Note: a rattle lasting only 1–3 seconds on a cold start is usually the dual-mass flywheel, not the chain.
Possible cause described: The timing chain on the 1.4 Turbo stretches, a different problem from the naturally aspirated 1.2 and 1.4.
Check for the garage: Listen to how long the noise lasts on a cold start and check chain stretch with a diagnostic tool before replacing it.

Faulty 4x4, heavy steering and a flat battery caused by the Mokka's rear differentialTransmission

Engine / equipment: Opel Mokka / Mokka X with all-wheel drive (4x4)
Period mentioned: 2012–2019
Symptoms: Together or separately: a 4x4 fault warning, loss of power steering assistance at times and a battery that drains while the car is parked.
Possible cause described: According to L'argus, the three symptoms have a single cause: a failure of the rear differential (the all-wheel-drive coupling). In France, Opel covered it as a technical defect for up to 5 years or 80,000 km.
Check for the garage: Note whether the 4x4 warning and the heavy steering appear together. With heavy steering, do not drive on. At the garage, have them check the rear differential and its module before replacing the steering or the battery.
