w222 3.0 bi turbo m276 de30 turbo misfiring coils
So I'm having an issue with
P13B2 00 Electrical fuse 1 for the ignition coil has malfunction
P035196 -- (and so on) The actuation of ignition coil 1 - 6 has internal component fault
P030400 --(and so on) Combustion misfiring cylinder 1 - 6
(im using autel608, my xentry has expired)
I have borrowed just in case, all coils and ignition plugs from a healthy cls400 and the problem still persist..
I have check all the ecu connector, cmp / ckp connector for oil contamination and they all fine. Although the timing in & ex solenoid has leak oil residue, i doubt that this cause the problem because as I handle many 400 series before, its only an external leaking issue (messy engine because of oil fumes)
I may have consider ECU fault but, i hardly find info on ME17.7.2(and above) that have internal ecu fault ( as the ecu are now protected with several fuses through the connection sleeve)
I have check the compression ration and all of them are fine within spec, 150+/-
I have checked fuse 101-106 for the connector sleeve in front fuse box and they all fine, maybe i need to disassemble the front fusebox?
I'm just at lost, and what haunt me is the P13B2 dtc, it might have wiring issue but I havent found any;
Have any of you guys experience the same problem?
Thank you guys
In a way it is good news that it is happening on all of your cylinders as that eliminates a lot of things as you demonstrated with changing the coils / plugs from a known good car.
