Hello bro.Xentry/DAS is like a software or something that i can buy and install on my tool? Or is another complete separate tool? I think I see some new Xentry updates to buy online but they said are for newer after 2015 mb models. So I conect this Xentry thing on my usual OBD and I search something to modify in ECU about engine tipe, 272 or 273 ,after I search in transmission software to modify something? What you saying about some ticking box,or central box?what you mean,?sorry bro some terms I don't clearly understand, because I'm french, write you from France.

Something like this😉

Where abouts in French France are you?

 

oh ****, half price of v8 with shipping. I thought i can install a software on my scan coding tool. Maybe i will try to a garage after installation v8 ,maybe they can help me with ECU updates, cheaper maybe 500$ on a professional. What you mean to tick box,can't clear understand everything. And what you saying about central box? You mean gearbox ecu? So engine ECU and gearbox ECU must make some updates? I'M in Toulouse south France, bro, i work here from 17 years, original from Romania 🇷🇴 east border.Thanks

 

Central Gateway ECU CGW is the hub for all the various Canbus circuits.

On my diesel, I told the CGW that it had the higher output engine and it totally changed the performance of the car.

There's the option here to tell the car what engine is fitted.

Also, there's a similar option in the Engine ECU. My icarsoftMB2 sees two engine ECUs on my W221 S500... The 6 cylinder one and the V8 one. Obviously the car is a V8 but it suggests that the software is present for both and just needs activating.

Once it is installed, I may be able to assist with programming.

 

Hello, bro, just thinking about you. Yesterday late evening I passed my scan tool on my car and wanted to tell you, was very late here, I find in the CGW gateway the option to switch from 272 to 273 like 3 or 4 different 273....options. I don't switch yet because v8 not installed yet...lol but i find this with my MB coding tool. I was trying for a little while to search same switch option in engine ECUs and gearbox ECUs, I don't find, but was late, today I'm working, will try another time to see if I find option to switch to 273 in engine ECUs and gearbox ECUs. I succeeded to find in CGW. I think I will finally succeed. Thanks bro. Actually I have another very specific technical issue, if you have time to read, I will try to explain: First The ML 350 is 4matic and my front diff attached to the upper oil pan, and the 2 front axels crossed the upper oil pan from right to left trough front diff and oil pan. Now in the pictures from the v8 seller i don't see that place where must have bearing and front axel must cross trough the upper oil pan and front diff...so I asked the seller told me he pulled the v8 from anMl 550 2011,and the front diff came attached to the oil pan and axels crossed the diff but not trough oil pan, just crossed one side and other underneath the oil pan. Online spare parts shops tell me the front axels shafts and diff are interchangeable from 350 to 500 to 550.I know oil pan may different from S class to E class to ML,but in general same engine, different oil pans.So now in my 350 front axels crossed trough oil pan, you think the v8 seller tell me the truth and the ml 500 v8 engine front axels can cross underneath the engine and same time can be interchangeable with the ml v6 how the online spare parts showing? Also I tried to see if can buy Ml v8 oil pan online and I don't find specific ML upper oil pan to se if it has the place where axels may cross trough,all oil pans online from 273 ,don't show the cross trough front axels hole. So what you think you're S class v8 front axels cross trough upper oil pan?or is not 4matic? You have any knowledge of specific Ml w164 m273, or Gl x164 m273 engine upper oil pan and front axels cross trough, or underneath? Sorry bro, I was so long. I go back to work. Take your time to answer, I'm not hurry, if you have this specific knowledge, before I buy the engine. Have a great day and nice weekend. See you, thanks very much

 

Glad your investigation confirmed my thoughts re the engine coding👍

For the diff, I have only ever had V6 diesel 4matics and can confirm that the front diff and axle tube are indeed separate.

Do you have your 3.5 removed yet? I suspect that you will find that you are mistaken and that the front axle/diff is in fact a single unit totally separate from the engine pan. The ML front subframe is a beast and may be obscuring some of the detail.

Talking of the subframe have you confirmed if it is the same as the V8 one?

A.quick internet rummage suggests that you might need to replace your diff with one from the V8. Just be careful to ensure that the ratio is the same... If not then you'll also need the rear diff. At this point I would consider investigating if the axles are the same or if the 500 ones are thicker. You're already committed, may as well do it right😉

The transfer case is common to all and can simply be left attached to your gearbox. (With the running gear out, it would be a good time to replace the chain in the transfer case as a preventative measure.

 

.Hello bro. On the ml350w164 the front diff is a total separate piece from the oil pan, but is attached to the oil pan by 4 screws, underneath the passenger side engine support bracket. So,the right drive shaft attached between diff and right front wheel. On the left side drive shaft attached between left front wheel and cross the oil pan, attached to the left side oil pan with a sealed bearing, thiis left drive axel is longer, continues crossing trough oil pan from left to right came out from oil pan right side trough another sealed bearing, and clips inside left side front diff. In back to front diff is connected front transmission shaft who goes in transfer case. So now i se online those front drive axels and front transmission shaft are suitable and interchangeable between ml350w164 and ml550 w164 v8. May be front diff is not same interchangeable between them or does not have same attached sistem to the oil pan pass trough front left drive axel. Ma be pass underneath oil pan at the v8. IF YOU are sure front diff is not suitable and interchangeable between them, i leave the project and i buy another renewed v6 350 engine. I don't want to change front and back diffs I have them with E lockers ,off road package and transfer case with dual ratio.but if front diff can work on v8,I doit. Don't understand almost all accessories are suitable and interchangeably between the two engines, oly steering pump is not. Starter, alternator, pullies ,belt all same sensors, front drive shafts transmission shaft all same, it may be the front diff also, i don't know. So I pictures from v8 seller i don't see have that place trough where front left drive axel go inside oil pan sealed with a bearing and coming out from right side sealed with the bearing to oil pan, and entering in left side front diff. In those v8 pictures that crossing trough inside from left to right is missing to the oil pan. THANKS

Would suggest that the petrol front diff is a similar arrangement to the diesel ones... So should fit?

 

Hello yesterday I took down the skidplates from 350,and i can confirm front diff transmission axels set-up is the same to ml500. My bad 🤭 👎, usually I don't loose details and I pay attention for small details. Doing documentation for a 272 v6 4matic, crankshaft bearings, piston arms bearings ,problem i have on my ml350w164, I do it wrong documentation on a m272 v6 4matic E-class,thought ml is same. To E and C-class is low body, and front axels crossed trough oil pan into front diff. NOT SAME FOR ML SET-UP. MY BAD. I concluded now front diff on Ml350 ML500 petrol and diesel are same set-up. I don't pull yet my engine out, because I still use it with bad bearings until I decide what engine i buy, v6 renewed or v8 renewed. I find those on Chinese manufacturers at 1.700$ each with harness and all sensors, spark plugs and coils.without exhaust and ECU. One of them i choose will come in 50 days, so I still use my bad engine. If I take v8 I must buy another steering pump and the cooling fan for v8 not same with v6. Engine mounts and brackets came with v8.Now i think I'm good. Sorry for my bad. Thanks bro
