Engine problems were noted not only for the Monjaro model, but also for Geely Tugella and Coolray. The reason is that the level of oxidants in Russian fuel is higher than in Chinese gasoline, which causes engine damage.
The engine control unit software update has already started for the Monjaro model. This upgrade allows the system to more accurately respond to fuel quality with different levels of oxidants, reducing the risk of breakdown.
Russian gasoline complies with GOST, but due to the high concentration of oxidants, this has become a problem for Geely.
The manufacturer recommends that all owners update the software to avoid damage — the work is free and takes a little time.
