On the 2021-2025 Opel Mokka 1.2 PureTech (EB2/EB2ADTS, 3-cylinder turbo petrol), 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; shed particles clog the oil pump pick-up strainer, starving the engine of oil, and the belt itself can skip teeth or snap. Because it is an interference engine, belt failure typically destroys valves and pistons. Affected cars also show excessive oil consumption. Stellantis acknowledged the defect and runs a PureTech compensation platform covering documented oil-consumption and premature-belt expenses on 1.0/1.2 PureTech cars, with extended warranty up to 10 years / 112,000 miles under conditions.

This issue also affects: Audi A4, Audi A1, Audi A5

Common Symptoms

Rattling/whining from front of engine
Excessive oil consumption between services
Oil warning light
Loss of power or sudden engine failure
Metal/rubber debris in oil

How to Fix

Strictly follow the (shortened) oil-and-belt service interval with the correct low-SAPS oil; replace the wet belt, tensioner and oil pump strainer preventively (many indies convert/replace early). If oil consumption or belt debris is found, submit a claim through the Stellantis PureTech compensation portal / authorised dealer; catastrophic failures require a full engine rebuild or replacement.

Typical repair cost:$700 - $6,000
