@Gransportmy point was that the engine falls within the range where there were bad balance shafts. The failures take time to manifest. If it runs well then it is likely OK for now but one should be aware that the possibility exists that it can go bad given the range of engines with the issue. That is all.
The balance shaft issue can be determined as follows: Mercedes-Benz, with the improved parts, has engine serial numbers that are higher than M272 Engine Serial No. 2729..30 468993. This vehicle has engine 272964 S/N 30 425118 which falls within the range of engines having the bad balance shaft (the timing chain-driven gear on it wears down). Whether a CEL is showing now or not does not indicate that the engine could have this problem tomorrow or two years from now. Some engines can go a lot of miles without showing the issue. When it does appear you will see faults showing cam timing issues which relate to the timing chain slipping or jumping timing and the engine will have serious problems at that point. I have looked at several beautiful cars that are basically worth maybe $1k or less since a replacement engine will be necessary, or to replace the balance shaft (not a cheap fix) if the rest of the engine is still intact. I bought a ML350 with a munched engine because of this and parted it out. I have an 07E350 right now I am working on due to another issue, but it has an engine with S/N 506393 and should be good with that issue.
This car has a 722.9 7spd transmission VIN WDBUF70J34A437569 Model Year 2004 Model E 500 Engine 113967 30 542791 Transmission 722901 00 013083
