Hi all. I have an annoying rattle/vibration noise coming from behind the pedal area. It seems to only occur in D, and then only when on either the brake or go-pedal.

I do have an intermittent gearbox fault error, but this has only started since I had a Ghost immobiliser fitted and the installer did say it can throw this error up. I have had my local LR indy check the gearbox and they said nothing was obviously amiss.

Any ideas?

2014 L494, SDV8.

I have read in other similar threads a suggestion that wheel/tyre fitment may be a factor somehow. Currently on Discovery derived 20" alloys with 255/55/20 Pirelli Scorpions.
