The BMB engine Reliability
- The BMB engine is a 2.0-liter inline 4-cylinder gasoline engine with a maximum power of 150 hp, featuring 16 valves and a DOHC (Double Overhead Camshaft) setup.
- It utilizes the FSI (Fuel-Stratified Injection) system for direct fuel injection and incorporates continuously changing valve timing technology. The timing is driven by a durable toothed belt.
- The engine is known for its longevity, with a resource of at least 250,000 km, and it can run on both 95- and 98-grade gasoline.
Most Common BMB Engine Problems
- BMB engines may face starting difficulties in extreme cold conditions (below -15°C). It is recommended to change the timing belt more frequently in colder climates like Russia (every 90,000 km) compared to Western Europe (every 180,000 km).
- The direct injection system in BMB engines can lead to carbon deposits on the valves over time, blocking specific channels and causing a noticeable decrease in power. Resolving this issue may require engine disassembly to remove carbon deposits.
- High-mileage BMB engines can experience oil consumption issues due to thin piston rings.
Tuning Prospects
- It is possible to reflash the BMB engine’s electronic control unit (ECU) for a power increase. This tuning can be combined with a cold air intake system and a catalyst-free exhaust to achieve approximately a 15 hp boost, which is a budget-friendly tuning option.
- While more complex mechanical modifications like changing camshafts, throttle valves, or installing a turbocharger are theoretically possible, experts generally consider them inefficient in terms of time and money. Instead, it may be wiser to invest in a vehicle with a more powerful factory engine if additional power is desired.
