Re: Variator Change
I have never heard of too much oil causing this Diesel sound, too little oil maybe.
Its best to check your oil level is high enough before going to the garage as if you have let it run down on oil they might not do the work on warrentee, so check its properly topped to the max line and then take it in.
Get all the belts (any belt they have to remove should be replaced) and all the tensioners/belt stretchers etc replaced. If you need the full parts list let me know, I had the work done recently and will have a full reciept at home if you need any more info.
