Unless you are very skilled at swapping computers on the MB, and have a ton of tools and time, I would sell the S550, and buy a S65 or S600.
The money and time you save will pay for the better car.

Swapping a different engine onto this vehicle will need lots of customizing...... Whether you try a M275 or M278 there will be to many differences. On another note the M278 and M273 DO NOT USE the same block. I have seen M272/M278 go past 300k miles on plenty of cars with no issues.

These vehicles feature a CANBus electrical system.
put extremely simply, there can be multiple units connected by a single wire ... which unit activates is determined by a signal sent through that same wire to that unit’s address. In addition, the controller for this can vary the voltage sent.
The likelihood that what’s needed to operate a different engine exists with your current electrical system is probably zero.

Read it again.... It doesn't say they are the same block. Yes, they are both V8, same bore pitch and ALUMIMUM engine block. Trust me when I tell you they are not the same block. How many have you taken apart?? I have only been working strictly on Mercedes Benz since 2006. Don't believe everything that is on Wikipedia.

S550
4matic is garbage. lets see... front cv axles... benz wants about $1000 each. Front differential was thought to be bad... replaced it only to learn the shaft that runs through the oil pan had to be replaced along with the oil pan. Then the transfer case inside the transmission which made a ton of bearing noise. Replaced the bearings and the noise went away however there was a vibration in the car from 4matic that I was never able to track down and fix. I sold the car for 3 grand a few months ago. Spent 6 grand trying to fix 4 matic. A s550 with rwd is the way to go... That motor was very reliable and I would have kept it if not for 4 matic

I apologize for bringing up this old thread. I had a similar issue with my vehicle recently; it turns out that I had a discharged battery which is a common cause for this issue. Then you can jump to the conclusion that you had a defective voltage regulator on your alternator w\that is responsible for charging your car’s battery. I did a lot of searches on this issue and came across an in-depth article that may be worth reading. Search for "Mercedes-Benz Stop Vehicle Leave Engine Running on YOUCANIC" and you will see an article that goes over common causes and possible fixes. You can read about it yourself. I hope this information can assist someone else with a similar issue.
