Hey everyone! So my MK7 1.8T Golf has an IS20 w/ APR tune. Recently its been throwing the EPC light every time I start driving. No light at cold start though. Here are a few possibilities on my mind:

1) Actuator voltage: current voltage reads 3.02 Volts. This is a IS12 actuator btw. I've read a few places that ideally it should read around 3.50-3.90 Volts.
2) Damaged BOV?
3) Turbo inlet: Not sure if I am just imagining it, but I think I might've seen a crack on the turbo inlet pipe.

Which one of these seem most plausible? Or any other possibilities to consider?

The BOV is not very likely. Adjust the voltage and see if it comes back. Obviously check the TIP for cracks.

Check for exhaust leaks at the turbo housing.
