Hi I have E32- it's 730 v6.
I had to change the gearbox oil, but I encountered the following problem.Bmw says that 3 litres of oil is enough, but my mechanic put 4 already and wants to put 1 more.he says it's not enough.How come there's such a big difference?
Is there a chance that my gearbox fits more than 3 litres, or my mechanic is wrong?
