What is the 2013-2019 Opel Mokka 1.4 Turbo Timing Chain Stretch / Cold-Start Rattle (A14NET/B14NET)?
The 1.4 Turbo petrol (GM Family-0, A14NET/B14NET) fitted to the first-gen Mokka and Mokka X suffers from timing-chain stretch and tensioner/guide wear, often appearing from around 80,000-100,000 km. A stretched chain alters valve timing and, if it skips, can cause serious interna… Repairs typically run $600-$1,800. Severity: high.
What is the 2021-2024 Opel Mokka Mokka-e Onboard AC Charger (Mahle 11kW) Failure?
The electric Mokka-e (and Corsa-e platform sibling) suffers from failures of the Mahle 11 kW three-phase onboard charger (OBC). When it fails, the car can no longer AC charge from a home wallbox or public AC point (often showing 'charging at 0 miles per hour' or charging briefly… Repairs typically run $0-$2,500. Severity: high.
What is the 2021-2025 Opel Mokka 1.2 PureTech Wet Timing Belt Degradation / Failure (Mokka B)?
The second-generation Mokka B (built on the Stellantis CMP platform) uses the PSA/Stellantis 1.2 PureTech (EB2) three-cylinder turbo with a 'wet' timing belt that runs submerged in engine oil. Fuel dilution and oil contamination cause the belt rubber to break down prematurely; sh… Repairs typically run $700-$6,000. Severity: high.
What is the 2012-2019 Opel Mokka Mokka A 1.7 CDTI Water Pump / Timing Belt Drive?
The 1.7 CDTI water pump is timing-belt-driven in this engine. When the pump seizes or its impeller fails, the timing belt can be ejected — leading to valve damage. Failure typically appears between 80,000-130,000 km, often before the recommended belt service. Repairs typically run $700-$3,000. Severity: high.
What is the 2013-2019 Opel Mokka Dual-Mass Flywheel Rattle / Clutch Judder (Manual Diesel)?
First-gen Mokka and Mokka X manual diesels (1.6/1.7 CDTI) commonly develop a metallic rattling or ringing noise from the bellhousing area, most noticeable at idle when warm or on the over-run. The cause is wear of the dual-mass flywheel's internal damper springs, sometimes accomp… Repairs typically run $800-$1,600. Severity: medium.
What is the 2014-2019 Opel Mokka Air Conditioning Condenser Leak / Compressor Failure?
The Mokka/Mokka X air-conditioning system frequently loses cooling performance at relatively low mileage. Common root causes are a leaking condenser (mounted low at the front and vulnerable to stone damage and corrosion), a defective expansion valve, or a failing compressor; 2018… Repairs typically run $200-$900. Severity: medium.
What is the 2015-2019 Opel Mokka 1.6 CDTI EGR Valve & Cooler Carbon Clogging (P0401)?
The 1.6 CDTI diesel (B16DTH/B16DTU, 'Whisper Diesel') in the Mokka X is prone to heavy carbon build-up in the EGR valve, EGR cooler and intake, especially on city-driven cars. The ECU infers EGR flow from the MAF signal, so any restriction triggers P0401 (insufficient EGR flow) a… Repairs typically run $150-$700. Severity: medium.
What is the 2013-2019 Opel Mokka Diesel Particulate Filter (DPF) Clogging & Failed Regeneration?
On the CDTI diesel Mokka/Mokka X driven mainly on short city journeys, the DPF cannot reach the temperature needed for passive/active regeneration and progressively clogs with soot, often as early as 30,000-50,000 km. This produces reduced power, increased fuel use, repeated rege… Repairs typically run $200-$1,500. Severity: medium.
What is the 2020-2024 Opel Mokka Mokka-e 12V Auxiliary Battery Drain?
Mokka-e (and closely related Corsa-e, Peugeot e-208, DS 3 Crossback E-Tense — all CMP/eCMP platform) drains the 12V AGM auxiliary battery during long parking spells, leaving the car unable to wake or charge. Owners report drain as fast as 3-5 days of inactivity. The MyOpel smartp… Repairs typically run $0-$350. Severity: medium.
