Hello Board, sure could use your help on this one.

Left my 2013 N55 135i idling at a slight angle, nose up, low fuel, in an effort to get car up to operating temp after I changed out the coolant reservoir and kept getting a low coolant alert. Purged it etc. All of a sudden it goes into limp mode and I get “misfires” on about every cylinder. Do my homework and it seems that at 91,xxx miles it’s might need plugs, coils, etc. Changed all the plugs and all the coils. Zr5tpp33 plugs. restart and runs fine for about a minute and bang, limp mode again. And again. Start researching what could be next, Camshaft sensor, crankshaft sensor, Vanos replacement etc. I have found many DIY’s on the Vanos replacement but I cannot for the life of me find a DIY on the camshaft sensors. Again the only codes I’m getting are misfires. No Vanos codes etc. I also have that radiator looking yellow warning graphic and a “low coolant” alert but nothing when I pull the codes.

Any thoughts?

Also, I did not check the gap on these plugs as the articles I read said they came pre gapped. I just looked and the box and it says .032. I believe our plugs are supposed to be gapped to .022. Can this cause the misfires?
