So I'm a new owner of a 2012 LR4, 33K miles on it. Have noticed a couple noises that seem odd.
1. Have some ticking that is noticeable at idle and lower RPM (up to ~2K or so). It is NOT injectors and does not sound "normal", but haven't heard any other 5.0V8 LR4's to compare it to. Sounds valvetrain related based upon pitch and frequency. Doesn't matter if cold or hot, can hear either way. Took it to the dealer for this one, but they say the noise is too faint for them to diagnose yet. They don't feel it is timing chain tensioner related, as in their experience you hear that when cold and it makes a big racket. Basically told me to bring it back when it gets worse (still under warranty).
2. When sitting at idle with radio off, sometimes I hear what sounds like an electric motor hum noise coming from the passenger dash area. Goes for a few seconds then stops. Then happens again within less than 30 sec - 1 min. I tried listening at the engine bay to see if it was coming from there, but I couldn't hear it or it didn't happen while I was listening.
Anyone else experience these?
Thanks
Rich
