My s-line wheels on B9 are 18 x 8 ET 40.
If you want to be sure about that take a wheel off and check the inner side of the rim,info should be on there

i wouldn see any problem fitting a 8,5 x 19 ET 43,meaning the wheel will be 0.5 inch wider and will be tucked in 3 mm more.
if you have an ET 40 they leave a tolerance for -5 + 5,meaning ET 35/ET 45 in youre case

Here's some info so you'll never have to be spoon fed again.

B9 A4 oem 18's .... 18x8 +40
B9 A4 oem 19's ... 19x8.5 +40

Your 19x8 +42 will tuck 8mm more than the oem 19's. Not a good look unless you run spacers. A 10mm spacer at minimum if your at stock height and more if your lowered.

Also Audi's run ball seat lug bolts. Most aftermarket wheels not specifically for Audi's run conical seat lug bolts.

B9 A4 hub bore is 66.56.
B9 A4 oem lug bolt size is 14 x 1.5 x 28mm (ball seat)
