What's up guys!

Here in Brazil we don't have many Audis, it is very hard to find car mechanics with Audi knowledge.

I have just got an A4 1.8 T 2007 and here is the thing:

My English is poor, I don't know the correct terms you use, but I will try to explain what is happening:

When I put the car key in the on/acc position, after this screen appears:

it shows the 'oil pressure' warning and then 'Switch Engine Off and Check Oil Level'.

But the engine is not on!

If I turn the engine on, the 'oil pressure' warning never appears.

Oil level is just fine, I have no idea wtf is happening.
