Thanks for sharing Bro👍 So the permanent fix was to contact the dealer & have the module replaced for free bcuz there's a recall on'em, cool😉 Honestly that was a weird looking module, it looked like it belonged to a space shuttle not a car😉 & totally agree with you, European car's do not have any source of right info in any scenario, it's only the tech's ability & experience to troubleshoot these complex systems🤔 Great work Bro, Stay Safe👍
So my 2010 S400 having the same problem. Towed it to a shop and got a huge list of codes . Was told the hybrid battery was grounded ti itself. Aux battery with 2022 850 everstart was fried and all sorts of mods. Towed it home, and 2 days later, I got in it, and the anti theft went off. I got into it, and it cranked right up. Drove it and the hybrid batt is at 66 % and charges when i hit the breaks. However, the Ac stopped working, and the other day it said brakes unavailable. wtf! Can't be the batterys am thinking
There is no permanent fix, only a temp fix unit the unit fails again. If you look at the wiring schematics, the signal the stop and start the engine is part of the ME-SFI [ME] control unit using the electric motor. The automatic start can only be triggered if an automatic engine stop has been triggered, the protection switch of the high-voltage battery is closed; there are no faults in the high-voltage on-board electrical system via the ME-SFI, and the high-voltage interlock is open. Additionally, if the car is fitted with Distronic Plus even more issues exist. If the radar sensor control unit (SGR) with adaptive cruising control, withdraws approval from the automatic engine stop, this triggers an automatic engine start and Disctronic Plus can accelerate the vehicle . If approval is withdrawn by the ACC [KLA]control unit, the fully integrated transmission control (VGS) control unit or the energy management system, the braking torque must be high enough, over a specified deceleration torque to trigger an automatic engine start. Furthermore, the entire system is being calculated by the ME-SFI [ME] control unit in order to calculate and check for plausibility, of the fuel injection and ignition coils function, depending if the start is a torque-led start or a speed-led start. In other words, 31 separate control modules or components are connected to the ME-SFI module which controls the Automatic engine start. Also, the Power Electronics Module doesn't just fail due to overheating, or location, if that were the case all replacement parts would fail, regardless of their quality, making replacement of the unit futile; but rather due to excessive amperage being generated by the Electric Motor switching between individual operation modes, i.e. motor mode/alternator mode. Basically, the motor has three busbars; these three phases are regulated depending on the operation mode of the rotor position. If one of these phases fails, or the temperature threshold is exceeded, and controlled protection of the system is not limited, excessive power can be generated and overheating of the Power Electronics Module occurs, resulting in the eventual complete destruction of the affected phased regulator within the Power Electronics Module. Mercedes does not want you to know the true facts, being that it was part of their flagship S-class model and their blanket refusal to acknowledge the true reason behind the nightmare, not to mention the cost to many unsuspecting customers, who are still buying this piece of junk!
@@DallasAutoDiag Great detail, thank you , how come they didn't mimic Toyota's hybrid system ? I read somewhere they used Continental , yes the tire maker company.
Hello I have a problem with my car Mercedes S-Class 400 hybrid of the year 2010, sometimes I press the Start Stop button and the car it refuses to start I have to wait 30 minutes 15 minutes 40 minutes several times it ends up starting I also have another problem the power steering is hard sometimes not all the time and the brake pedal sometimes it is hard too, I brought the car back to Mercedes for a diagnosis I was diagnosed and I was told that the problem comes from the ECU that manages the hybrid that is at the bottom side gearbox and maybe the hybrid battery too but for me they are not strong on the flanges the fault codes of the diagnosis from Mercedes is: P0A6000 and also the code P0A6300 and also the code P0A5D00 I would like to know if you can help me solve the problem please is it the hybrid battery that is out of service or the ECU that charges the hybrid battery. Can you help me
Hi, did you solve the problem? I got exactly same problem like yours, sometimes starts sometimes refuse and after 10-15 min starts again. Please let me know. Thanks.

Lol
By the way, look me up on facebook it has my watsapp contact there if you want.
@@DallasAutoDiag Thank you soo much for your support, will do that, it's an honor for me😍

Excellent efforts 👌
Thanks
Do you convert S400 to a s350? And cancel out anything hybrid?
Sorry i don't
Is this recall just in Us/ Canada or worldwide?
Not sure. You have to call your local MB dealer
Hi what is the real name for the power electronics module so I can order it
You have to step outside of your comfort zone in order to grow.
Thanks for your advice.
How to find you in Facebook or whats app? please
Same name and logo
@@DallasAutoDiag ok thank you ❤️
What diagnostic software are you using? Link? Thanks
