The chirp is probably the direct injection fuel pump.

If the ticking sounds like a typewriter then it's the direct injectors.

The thing is, direct injection requires absurdly high pressures (up to 3000psi) to overcome cylinder pressures, so the system is going to be noisy. I know someone with an Audi TT-RS and it has the same typewriter sound.
