Hey brains trust,
I need your help please! I'll try to keep this short...
I have 2008 and it was running fine. A little while ago the Secondary Air Pump made that screeching sound telling me it was dying. It made the sound one more time then died; no Check Engine Light. A few weeks later, I got a CEL and when I connected the OBD2 it gave me the famous P0410.
So I bought a Secondary Air Pump (eBay) and replaced it. To be doubly sure, I bought a Secondary Air Injection Valve (eBay) and replaced that too. I've been driving it for about 100 miles and no CEL; great! However, I need to perform the Driving Cycle since I've got emissions coming and I'm still showing the Fail (red 'X') for 'Cat' and for 'Air'.
So today I went for another drive trying to get rid of these 2 failures. After about 40mins of driving I connect the OBD2 and I get a Pending Code ... P0410. The CEL did not come on, but it will next time it fails again.
Question: What the bloody hell else could be causing this P0410 given I replaced most of the Secondary Air parts?
I must admit I don't hear the Pump going when I turn on the car, but not sure if I should hear it given it's new and maybe really quiet...?
Edit: I thought it could be the EGR given the old Secondary Air Pump had water in it, but the OBD2 indicates the EGR is fine.
Any help appreciated because my Emissions deadline is coming and I'm genuinely a bit lost.
Thanks!
