2009 BMW E63 M6, Sapphire Black
Yeah it’s weird. Ecs only list the bmw coils in their kit.Where did you buy them, don't see them at ECS?
Here’s the link. I just tried to find it again but couldn’t. But went back to my old orders and got it. It’s weird.Where did you buy them, don't see them at ECS?
What was the issue with fuel system?@SunglassesGuy I think he's referring to the kits they sell. The BMW kit for $1300 or the ECS assembled one for $750.. Which really brings my point to light. I'm fine with the $1300 since its the proven coil choice.. but what are the chances of me getting the $750 kit with new spark plugs too and maybe having one dud or two. That $450 price difference could go towards plenty of other wear items on the car like a front set of Zimmerman rotors.. But I rest my case. I'd just rather have a running vehicle than chance the dud or crap ignition coils with all the variance of stories good and bad I'll just be going BMW OEM for the spring.
You have a leak inside the tank, that's why fuel is not being transferred to the pump side.What was the issue with fuel system?
Follow what @platii says, I used a ratchet strap to pull the lines through, I pulled my system 3 times because of a loose connection or leaky fitting. What was the icing on the cake for me to get a new unit was a pinched line preventing proper fuel flow. Once the line was fixed and I gave adequate time for the fuel pump to prime by turning the ignition on and off without turning the car on about 5 times for 30 seconds a piece.. What is your mileage?What was the issue with fuel system?
I have same issue. Left side (fuel filter side) has all the fuel. Right tank is empty. If I put some gas manuelly in the fuel pump side, my car starts without issue but it die after few miles. Because fuel pump pushing all the gas through filter driver side tank but fuel filter is not pumping back to fuel pump side. Both brand new pump and filter/sending unit.
Apprecaited for help.

God bless you. I will take fuel pump and filter out and see whats going on. I hope I will success.You have a leak inside the tank, that's why fuel is not being transferred to the pump side.
You either kinked the line while passing pulling the lines from the passenger side to the driver side during installation, or one of the connection after passing pulling the lines at the filter side is not properly connected and it leaks fuel.
Read the thread carefully and pay attention to these posts, the answer is there for this case, posts# 172,181,182,196,206.
The best way to pass the lines is tie a rope around the connection before pulling the lines during removal and tie the same rope to the new connections so they don't get tangled and pull the rope and lines carefully to the filter side again.
I post to the bimmerfest, somebody gave me this link. They say that somebody has similar issue on m5 forum. So I came here. Apprecaited for all your help. Thank you so much@mrbattals
This is M5 forum, many things doesn't apply to your car, if you post in the 525 forum you may get better information related to your specific codes.
I think the fuel tank and pumps principle is similar.
First fix the fuel problem delete the codes and test again.
Tank cap fault, code be blocked carbon canister (you can apply air to the inlet to clear it) or bad tank vent valve.
Mixture faults most likely caused by blocked air filter, bad or dirty MAF or wiring, air/vacuum leaks, blocked injectors, bad spark plugs, oxygen sensor or cat, many things, this require knowing full history of the engine and multiple testing to know what is the mixture condition, is it lean or rich and why the DME is throwing codes at you.
Using ISTA/INPA BMW software (free software) will help you do some testing/view values/ and set a path for you to troubleshooting.
