Thanks for the reply. I only showed the eBay list because it was the only one available for fuel filter location for the searches I could find.
I was thinking I am having a fuel delivery issues as my X5 has been surging under acceleration (under load) and now engine malfunction reduced power light is on. I had the plugs changed last week because I thought at 70k miles it could be a plug. No codes stored or active during scan. I'm now thinking a coil issue, due to surging issue and now engine/malfunction light has just come on light. I'm still under CPO warranty, so another trip.....Thanks appreciate it.
