I would also like to ask for my case, I went to Perodua Service Centre this morning for my MyVi second service and after inspection, they suspect possible oil leakage under my vehicle.

They suspect the root cause of the leakage is due to broken
1. Drive Shaft Oil Seal
2. Drive Shaft Boot

They still couldn't 100% confirm on this, so they asked me to drive for a few weeks and get back to them to check. I actually noticed some oil drops under my vehicle few months ago but that just happened occasionally and I don't feel any issues when driving.

And then I asked them whether can these be repaired or must be replaced. They said those part must be replaced if found broken. So, may I ask if anyone knows the price range of the above items?

If the price to replace at Perodua Service Centre is to high, can I find a better alternative outside? If I do, will this void my warranty?

Thanks for the advice everyone, I never think of my warranty. Maybe after a few weeks, I will go back to the service centre and ask them about this
