Common BMW Issues (and what to do)
Oil/Coolant Leak While Driving
Oil filter housing leaks often go unnoticed because they typically occur only while the engine is running. Since the housing sits high on the engine, you may lose coolant or oil without seeing signs at home in Tualatin. A quick inspection at German Autowerks can confirm whether the housing is leaking and prevent further engine damage.
Battery low or draining (After replaced)
A BMW that continues to drain the battery usually has an unregistered replacement battery or a failing alternator. Battery coding is required on BMWs to ensure proper charging. If skipped, electrical issues can persist. Diagnostics allow us to determine whether the cause is coding, alternator output, or a parasitic electrical drain.
Smoke Inside the Vehicle
Smoke entering the cabin is commonly caused by a leaking valve cover gasket allowing oil to burn on the hot exhaust. This area sits close to the cabin filter, making fumes easy to draw inside. Repairing the gasket resolves smoke issues and prevents further contamination.
BMW Transmission Shifting Poorly
Rough or inconsistent shifting is often related to degraded “lifetime” transmission fluid. As the fluid ages, it darkens and loses lubricating properties. A transmission service with fresh fluid and filter restores smooth shifting and helps prevent long-term damage.
BMW Timing Chain Rattle
A rattling timing chain is a serious concern that should be inspected immediately. Several BMW engines are known for timing chain wear, and delaying repair increases the risk of catastrophic engine failure.
BMW Turbocharger Wastegate Rattle (Code Set)
A wastegate code or metallic rattle may indicate worn linkage or internal turbo wear. Because BMW boost issues share similar symptoms, accurate diagnostic testing is essential to determine the exact cause.
Carbon Build-Up on BMW Intake Valves
Direct-injection engines naturally build carbon on intake valves, reducing airflow and causing hesitation or misfires. Walnut blasting is the recommended cleaning method to restore proper airflow and engine performance.
