I have an E46 2002 330CI auto. When I turn the ignition on everything seems ok. When I select drive (D) on the autobox the orange oil light comes on for roughly 10 seconds then goes off again. If I turn off, wait a bit, turn on, I can't replicate it. But if I leave the car for a while and try it again, the light won't come on until I select Drive. I've went through N and R and they're ok, it's only when I select D.
Any ideas? Is it low oil in the autobox? I've checked the engine oil level and it was a tiny bit low on the dipstick, topped it up by about 1L and it's at the max on the dipstick now. But the orange light still comes on.
Thanks for any advice.
