Hi all, First post... my corolla wagon makes a funny sharp hum noise when easing off the accelerator when car is warmed up . Also does same noise when warm started or shifting to park from drive(auto). Anyone on here able to help or experienced this issue ? Car has done 145,000km and just had service (mechanic couldnt work out the noise) recording of noise below Thanks, James Voice 001.m4a
