This belongs in the MKIII section. <moved>

We'll need some more info to help. First off you should check for diagnostic codes, see the MKIII FAQ section for a thread on how to do so.

What engine do you have 7M, 1G, 1JZ? Is the car stock of is this a turbo swap? Is the engine from a different market? Ie: Is it a JDM or USDM engine, not AUDM.

A bad CPS may account for everything but the oil pressure. If it's anything like the USDM vehicles the AUDM gauge and ECU may not be compatible with the JDM oil pressure sender.
