So I got the bad news from mechanic today that the issues I was having with 4WD was because there was water in the front diff and need a new one. Apparently got in through some leaky diff oil seals. Has anyone else had this issue? The breather is up in the engine bay and I know I haven't gone through any water that deep.
But he also mentioned that he can't clear a fault code to do with the YAW sensor. He mentioned that it could be to do with the stability control. I remember the light flashing a few times when I first bought the car as the tyres were bald and slipped around a bit. But since I got new tyres it never flashed up again. The button to turn it on and off doesn't seem to do anything either.. doesn't matter if I hold it down or just press it. I did a bit of a search and there isn't much info on the topic. Would anyone know what could cause the issue? Toyota quoted $1200.00 for a replacement YAW sensor but said they have never sold one before.
