So, my car is 2015 cls63s, i put 39,000 miles on it. It's modifed include Spark plugs, air filter, catless dp, IPE cat back exhaust, lowering spring and tune. Car was running good until last i month i installed my lower spring, at that time, car start to misfire,first time i went to dealer, they didn't see any codes, so they just updated my ecu then gave the car back to me, but the problem is still there, this time the CEL start flashing,i was read code show cylinder#6 ignition coil fail P0356, i went to dealer second time, then they replaced the igintion coil of #6. It looks like the problem has been solved, but just one day after I took my car back, another ignition coil broke down and the car start misfire again, this is time code is P0357=iGNITION COIL g PRIMARY/Secondary circuit. Now its back to dealer again! Has anyone encountered a similar problem! need help!!
Here is the invoice of second time dealer give to me.
Who did your tune? Was it canned or a dyno tune? Very obvious the dealer is looking to status 8 your car at this point, something in your mods is causing this (obviously not the springs).

its eurocharged，actually the first time i went to dealer，they updated my ECU，which mean after that i was running stock ecu file，but the problem is till there，It looks more like a circuit failure，in my engine bay，i have the exhaust valve control module，I wonder if I broke the module circuit when installing spring?i dont know if that is possible

I really doubt you broke something having to do with your ignition system while installing lowering springs. My point is that it may have been something to do with your tune. Did they dyno tune your car or just flash it?
