Hi all, I recently ran a ODB II on my car and it’s came up a couple of fault codes, as follows: P20EE Nitrogen oxide (NOx) sensor, catalyst, bank 1 - efficiency below threshold Status: Pending Engine control unit P003D(75) Intake camshaft profile control A, bank 1 - stuck on Status: Test failed, Pending, Test failed since last DTC clear, Test not completed during this operation cycle And to add to this, it’s regening every 100 miles and recently went into limp mode with a coil light on the dash, but it’s running normally now. Has anyone had these faults? And if so, what’s involved and the cost of these fixes? Thanks in advance
