Hello guys. I have a problem with my 2005 s600. I have a misfire at cylinder 1-2-3-4-5-6 from the start. Any suggestions or help will be appreciated. Thanks

Most likely the coil pack, second most likely is the voltage transformer between the two coils. Look at www.v12icpack.com.

what I would do first is rent, his rebuilt, voltage, transformer from him, as it can be easily changed in five minutes on top of the engine. If that solves it, you keep the rental voltage transformer. If it doesn’t solve it, you return the voltage transformer rental and buy the coil pack.

This is the most common failure item of the car

start searching on these forums and you will find lots of info on this subject, which is not rare.

When you're misfiring from an entire bank then it's the voltage transformer.

Do NOT change parts WITHOUT a SDS diagnosis (i.e. reading MB fault codes).
The ECU may be shutting down these cylinders deliberately to protect damage to the cats.

Exactly what Kraut said. Never throw parts at the problem, get a diagnosis first. A diagnosis over the internet is impossible, so find a mechanic that knows this platform.
