Bought an IS220d SE-L a few months ago. Also well with it, just over 51k miles. I've started to notice a noise coming from it when idling, not overly loud but like its revving slightly higher(although doesn't show on rev counter) and when I push clutch in it goes back to normal. The clutch also makes a strange noise when engaging but not when disengaging. Like a spring noise. Hard to describe, sorry. This is my first post so hello to everyone, I've just changed to this car from owning SRI Vectras for years.
