DEMA motorral szerelt járművek listája:

Engine DEMA commonly faces issues like carbon buildup on intake valves, turbocharger wear, and timing chain tensioner noise. For diagnosis, listen for rattling noises at startup indicating timing chain tensioner wear and use a diagnostic scanner to check for turbo boost pressure faults. Prevention includes regular use of high-quality fuel, timely oil changes with manufacturer-recommended oil, and periodic intake system cleaning to reduce carbon deposits. Solutions involve cleaning or replacing affected components: intake valves may require walnut blasting, turbochargers might need repair or replacement if worn, and timing chain tensioners should be replaced promptly to avoid engine damage. Regular maintenance is key to longevity.
