hey guys aoa.
my brother owns a 2013 vitz and since he bought it i.e a few months back whenever we accelerate heavily it starts to smell like something is burning once the cvt is is action, i read about this in a few places, it said that this might be due to old cvt oil and the cvt oil should be changed after 40000kms ,since we bought the car at 45000kms I decided to change the oil, once we got the old oil out the mechanic said it was clean but I still changed it because I really hated this problem (the mechanic told me this smell is not related to the cvt oil),after the oil change I was very happy that theres no longer going to be that smell , I put the car under heavy acceleration and for a while I actually thought the smell has disappeared but right at that time the smell had started again, can you guys please help me what the cause of this can be as its very annoying and might be causing some serious damage to the car. thanks in advance(Y)
