Oil type and threaded screw advice

[TaylorK]

I was hoping somone could help me out. I noticed my car is low on oil and I'm unsure which oil to use as I don't know if I have a dpf or not. My car is a 2007 a3 sline with the 140bhp tdi engine and it is serviced yearly. Hopefully that is enough information to go on.

Also, my numberplate bulb has gone out... but I cannot change it as it looks like the screw has stripped and won't budge. Does anyone have an idea of a way to remove it?

Those screws are hopeless!! I had to use long nosed pliers on mine to pinch the screw head and twist it out failing that might be easier to just buy a new unit, not too expensive
