2010 X6M engine ticking sound and misfire when warm
Hello everyone! My 2010 x6m has 65k miles. After 5 min of driving, engine developing ticking sound under normal acceleration and when RPM reaches idle speed, cylinder 5 starts to misfire with codes 2B1A 2B23. Sound is coming from high pressure fuel pump. After the car parked for an hour, ticking sound and misfire disappear when engine is cold. Please help

Could be timing chain…I had a similar issue. Rod bearings were shot. Expensive…
