sorry it did not work for you R.

Sorry to hear that ,I cant think of anything else as I had stopped when I changed the O2 sensors. Mind you I was chasing this starting 10/15 started with cleaning IACV,DISA, MAF and inspecting the intake boots,whatever was in the area,didnt touch the fuel injectors but treated 2 full tanks of gas with cleaners,didnt work,still getting intermittent P1093 code,lived with it and reset as needed, only thing i changed was the fuel filter since it was original at 120k,up until 3/16 when it was warmer when I was able to check the O2 sensors....hope somebody on here with more expertise can help you out, try our brothers at e46fanatics, see if they can help you out...X5 3.0 now has 125K miles, nothing new added since the last oxygen sensor was changed,no P1093.

Previously, cleaning the idle control valve resolved this issue for us in 2016. Well, 42,XXX miles later and the P1093 code is back on.

Just replaced both pre-cat sensors again, no luck there.

Cleaned my MAF with MAF specific cleaner, put a big bottle of Lucas complete fuel injection system cleaner in the tank. Drove 130 miles this week, the light came right back on.

At 132 miles, the service engine soon light turned off on its own! The code was gone for about a day, several drive cycles. Then it returned. I thought this was quite unusual. Anyone have some insight?
