2.7T V6. Camshafts were removed without setting to top dead center. How should I reinstall to make sure timing will be correct?

Actually, I believe when the locking tools are in place, it is #3
that is at TDC.

Always use the required tools for this kind of job.

2markings on the camshaft must be in line with marking on the bearing caps. Everything I've read, between and AllData says TDC on #1 and only mentions that you should make sure the marks are properly aligned.

Unless you looked down the spark plug hole on #1 cyl, you would NOT
know that #1 was NOT at TDC when the Factory Alignment Tools are
used to put the engine at TDC.

This is why people get into trouble when doing timing belts ot head
jobs WITHOUT the correct tools.

They line everything up to #1 TDC and wonder why there is a problem.

The Audi Service Manual doesn't even mention #1 TDC. It just says to
align the TDC marks.

It's not until you look at the valve lobes or check which piston is
at TDC, that you notice that #3 is the one at TDC.

The markings on the bearing caps is for checking intake & exhaust
camshaft alignment (number of links in chain).
