Some 'normal' oil in 'atf only' box
Hi,
I just found out that my wife put some normal oil in the "atf oil only" part 2 days ago. Drove 200km since, didn't feel anything unusual. Apparently the warning light for oil came on so she thought she's add some.. Says she was "surprised it was almost full so added just a tiny bit". Doubt I'll get more accurate numbers.. So do I need to go to a mechanic to have it drained asap?
It's a 120d with manual gearbox
