P0492 that (really) wants to stay... Over the last month I’ve been troubleshooting a [P0492] Secondary-air system bank 2] error, which triggers the CEL of my ’03 Boxster S (DME 7.8). I’ve taken apart the entire vacuum system, replaced any/all components that were faulty/worn out, but the error keeps re-appearing every couple of days. Now, the car runs perfectly well, it’s just I don’t enjoy a CEL light in my dashboard… With Durametric, I can validate: Secondary air pump (also works during the first 90 seconds of a cold start) Secondary air pump solenoid (I can hear it clicking) Can this be a VarioRAM issue? I’m asking because VarioRAM is installed in bank 2 in a Boxster, whereas the secondary air pump is in bank 1 (not sure if the description means physical location in the car or not…) Both are connected to the same vacuum system I cannot trigger the solenoid using Durametric. I believe they call it [intake Pipe Swithover] – can somebody confirm if this is the right activation?? I’ve also confirmed the solenoid works OK on a test bench - but again, doesn't work with Durametric CEL usually comes on if I’m just cruising (very rare) of after a cold start, during the first 5 minutes of driving. What am I missing??
