Hi guys, me again with more problems.
So I ended up putting new plugs and delphi coils in my e90 335i.
I warmed it up three times, and my car automatically took off its engine light for misfire cyl 2. Everything ran great. However, yesterday I let my Dad take my car to work and he said the engine light came on when he was coming back. I checked to see the codes with the jb4 and there are 9!!!!! However, the jb4 only read out 7, for two of them it kind of lags, it does not show the speedo and tach moving but it still waits for the two codes to go through.
Here is what the JB4 gave me:
2E7
2E19
2E1B
2E1A
2E1D
xxxx Tach and speedo didnt show these two codes?
xxxxTach and speedo didnt show these two codes?
29F5 I know these are cat codes which is fine
29F4 I know these are cat codes which is fine

What is going on with my car?

The 2E codes are for "firing" cyl 2, 3, 4, and 6.
I just replaced new coils and plugs, what can this be?

Make sure you seated the coils properly or you will get those codes.

reseat the coils and make sure they are fully on the plugs

also what plugs? you gap them or they were pregapped

[IvansE90]

Bosch ZGR6STE2 plugs, I did not gap them.
Delphi Gn10571 coils.
I pressed the coils really hard to make sure they are seated. Here is the weird part, my obd scanner only shows the 2 cat codes. Is the jb4 glitching?
And the other thing is, the car runs good with the new plugs and coils even with these codes. I deleted these codes with jb4 and will see if they come back but im stumped. P.S my car does blow white smoke at times which is not condensation! However, i am completely catless with muffler delete.

Make 100% sure you plugged the connector onto the coils as far as you can. Those coils are for N55 and do not have the mechanism that "pulls" the connector onto the coil when you close the lever on top of the coil like the N54 coils do. You have to push the connector as far as possible, then close the lever. If you don't you could get misfire codes.

[Jeff@TopGearSolutions]

Yea as others mentioned I dont think the coils are seated fully.

If they are still fully seated then you may want to look into your white smoke issue is that is a different problem.

Otherwise I'd reinstall a fresh map and firmware on the JB4.

I will check that today when i finally route my usb cable to the glove box!

This exact thing is happening to me and jb4 was showing me codes for 2step?

I get the same 2E1x codes randomly. Car doesn't run any different and I do have a 2-step so.. yeah. I just clear them.

I recently purchased a brand new set of bosche coils and got a bad batch. No idea which one was bad, but didn't want to deal with it so returned all 6 and purchased the new and updated Eldor ignition coils off ecstuning. All my problems went away and the car pulls hard Here's the part # just in case:12138657273

I would go ahead and replace them. I had the same codes appear when I installed my jb4 and I didn't replace the coils. I ended up replacing all of them and no more codes.
