So, Mercedes have made a mistake 😕


It's needs to be drained and then re serviced with the correct oil. They have admitted fault and apologised.
It was only noticed as a different tech was topping it up once upto temp and notices the oil was gold going into the box so he immediately stopped and raised the alarm so to speak.
They said they will flush and it should be fine but any issues they will sort it.
Will it be ok ?

Otherwise you will always be "worried" about breaking down in middle of nowhere USA and stranded and then having to pay for a new gearbox since they were reason it failed.
go by mileage not months. so ask for it out to 150K miles.
