BMW 528xi lifters making a ticking noise not yet fixed on BMW 528xi

Some BMW 528xi owners report experiencing a ticking noise from the lifters, commonly attributed to faulty hydraulic valve lifters that may require updating or replacement. While a lifter bleed procedure is typically performed by BMW to address this issue, some owners find it does not provide a permanent fix. Additionally, low oil levels have been noted as a contributing factor, as running the vehicle hard on insufficient oil can lead to ticking noises. Owners are advised to seek the assessment of a reputable mechanic familiar with BMWs to accurately diagnose the issue. If the noise persists, an inspection of the pushrods in the valve train for damage or bending may be necessary, as these can also cause ticking sounds. Repair costs for lifter tick issues can vary significantly, making it important for owners to understand their options and associated expenses to make informed decisions.
