Thanks for asking your question. I will try and help you out. Sorry for the delay.

If your fault says intake valve oil pressure, this indicates a low intake valve oil pressure. I've seen this many times.

This code is cause by several things.

The first and most common is a leak on one of the Iva housings.

Second is a leak at the Iva control valve

Lastly is a faulty Iva pressure sensor.

Please reply back if you need more help or have more questions. I am happy to assist.
