Hello and I apologize if wrong forum but it's a general question and I'm desperate to fix this.

Hi,

I have a 2012 Cl63 Amg 59k miles bought at auction with flood damage title but no sign of water intrusion

and injectors on passenger side not actuating in Xentry test with a new ECU. New plugs wires and coils and 02 sensor. Still no actuating of those injectors slow acceleration. I cannot locate area of water or flood intrusion. Really at a loss. I'm getting misfire crankshaft errors below. Any ideas? Someone removed the injector soundproofing or padding insulation and high pressure fuel pump insulation. The Sam's have been checked and replaced the fuel pump relay just in case. Any help would be aporeciated. Any specific steps with Xentry?

Do you have DTS Monaco? Xentry sucks for diagnosis unless you are paying for the online version. If I was you, I would connect through Monaco and see what other modules are flagging. 1864 and 1764 seem to be camshaft position sensor issues. Look in your IPB and see if you have a magnetic cam position sensor/adjuster on the front or back of you headers. Those are known to go bad and have had recalls, not sure about your model, but yeah. Also have wheel speed sensor error there from the looks of it. From the looks of this, you have a camshaft position sensor failure, not anything to do with the crankshaft imo. Some models have a magnetic timing adjustment that can, on the fly, wind back (or forward can't remember), the timing which could, in theory, cause you to have misfires, poor performance, and other things, if it was not functioning as it should. That wheel sensor thing can also cause a myriad of issues. Brake light switch and wheel sensor were the two things that cause me to chase my tail the most... But yeah, Monaco will give you way more detail than the vague crap you will get from xentry. Also if your testing equipment is not perfectly set up, you can get only partial compatibility within xentry for actuations. Adaptations, unless you want to spend the $60K a year or 100 a day or whatnot, are also non-existent in Xentry. DTS or Vediamo are the way to go myguy.
