Before you buy a used Opel Mokka (B).
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.
The essentials.
- 6 documented, sourced faults across its 3 engines.
- 2 of them depend on the equipment or the production date: ask what this car has.
- 1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
- According to the data we have, the engine with the fewest documented faults is the Mokka-e (Electric).

Which engine has the fewest documented faults?
| Engine | Documented faults | Recalls |
|---|---|---|
| 1.2 Turbo (PureTech)Petrol | 32 with conditions | 0 |
| 1.5 Diesel (BlueHDi)Diesel | 31 with conditions | 0 |
| Mokka-eElectricFewest documented | 1 | 1 |
According to the data we have, the engine with the fewest documented faults is the Mokka-e (Electric).
By fuel type, the one with the fewest documented faults is: Electric.
We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.
Official recalls: ask before you pay
A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Opel dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 6 checked
Timing / lubrication
Look out for: Oil pressure warning, hard brake pedal or reduced assistance, oil consumption, blue smoke, squeal at the front of the engine, turbo whistles or loses power.
Ask them to check: Measure the belt through the oil filler opening with the manufacturer's tool. Confirm whether the vacuum pump campaign was done.
Exhaust and emissions (AdBlue)
Look out for: Emission system fault message and a “starting impossible in X km” countdown, AdBlue/UREA warning and engine light.
Ask them to check: Diagnose with Diagbox or equivalent: AdBlue pressure, flow test and tank temperature.
Timing system
Look out for: Rattle from the top of the engine, loss of power; in severe cases the chain breaks and the engine fails.
Ask them to check: Ask the dealer whether the car is in the campaign (free inspection and replacement if needed) and whether the 8 mm chain is fitted.
Charging (on-board charger)
Look out for: AC charging (home or public) becomes erratic, drops from 11 kW to about 7 kW or fails completely with messages such as “Charging paused” or a critical error. DC fast charging keeps working.
Ask them to check: Test charging on a three-phase and a single-phase AC point, read the charger codes with DiagBox and check whether it has already been replaced and by which version. Claim warranty or known-defect treatment before paying.
Automatic gearbox
Look out for: Hesitation or a jolt between 1st and 2nd, torque converter shudder in traffic, harsh or delayed shifts and a gearbox fault warning, especially on 2017–2019 3008s.
Ask them to check: Check oil level and condition, update the gearbox software at the dealer and, after an oil change, record it with DiagBox and reset the adaptations.
Electrical and electronic systems
Look out for: Engine or electrical-fault warning light, a hot or burning smell under the bonnet and, in extreme cases, an engine-bay fire.
Ask them to check: Check the recall by VIN; do not pressure-wash the engine; with the warning or a burning smell, stop and park outdoors.
