Hi,
First post on here! I recently picked up a 2012 150 GXL D4D.
So I've noticed that virtually every time I hit the brakes there's a whirring electric motor noise coming from behind the dash. It runs for about 2-3 seconds then stops until I hit the brakes next. I'm pretty sure it's the brake pressure booster running which makes a lot of sense. But I didn't expect it to:
a) run every time I hit the brakes, and b) be so audible from inside the cabin.
I can't find any mention of this noise on the internet so wondered if this was indeed a normal thing with the D4D Prado or something unique to mine? :S
Any guidance would be hugely appreciated!
Cheers,
Matt
