The Engine number depends on the type of your car and model year. Usually written down in your Datasheet. I can see it with the vin in my EPC/WIS.
The number usually is located underneath the engine, not easy to describe. In the area where the engine and transmission meets. http://www.teilehalle-fm.de/ebay/Fot...4/CIMG9664.JPG
Very interesting. I thought all those issues were sorted by 2000, I have seen many M112 engines do over a million Km's in Asia without being touched but serviced to the book. This has always been considered a bullet proof engine.
boull, I meant to post yesterday but got tied up in trustee meetings.
When your tech fits the new engine tell him to ensure that all vacuum lines, breathers & the EGR circuit & valves are clean. Also make sure that the runner flaps etc. in the inlet manifold are clean. They get fouled up over time due to captive breathers.

Purely out of interest, will the 240 ecu run the 320? If the injectors are relatively slightly larger then the duty cycles might be spot on? Otherwise problems in open loop mode?
New engine deployed.
new issue came up ...
we recoded the differential to know that the engine has been swapped for a 320.
the thing that happens while driving is that when i floor it, as the RPM hits around 3000 or 4000, it cuts off and break your neck.. and then re-continue to close on the gear it is in.
the mechanic said that the issue is that the differential would need to be swapped with a 320 one!
what's next? ur transmission cannot sustain! u need to change that as well? :@
The differential simply puts the power to the ground...it's a set of gears...unless it's broken it shouldn't cut out at any specific RPM range...If it was broken it should've been doing the same thing with the old engine as well.

its not the differential, its the interaction between the computer and the differential.

nop that is being done on the new engine only...
he told me that since the engine is bigger now, and the differential was made for a 240 engine, that might be the issue...
now you threw me in a loop.. i dont want to pay money for something that will not fix my issue. then why is it that the numbers of the differentials are different?
we tried to see if the fuel pump was the issue, we linked a gauge to it to see if it is cutting the fuel on that selected RPM, turned out the fuel pump is working fine (around 400 something on the gauge)
this is the video i have done, parked on the side, then took my lane and floored it (D).. what you see it that when the RPM hits 3000rpm, lost like 200RPMs, (something is wrong) then jumps back like a bullet!
Ok that's better. Does it do the same thing with ESP off...have you tried putting it in dyno mode? Does it do it in every gear...what if you shift manually?
^ +1 - the yellow triangle flashing indicates that ESP is kicking in. This indicates that the system has detected some wheelspin or loss of traction, so it cuts the engine to help you regain control.
Yeah if it's not that then I would probably start checking the new engine...MAF, injectors, the fuel system in general, TPS etc...all this assuming it's not an ECU issue.
If the differential was an issue it should be making some sort of noise...plus start troubleshooting with the items that were changed, not components that worked fine before the "mods".
+1 not the differential, an open differential cannot do anything at all except work normally or fail catastrophically and have pieces of it everywhere. The different numbers probably refer to slightly different final drive ratio or a slight change to the design.
I still want to know what you do to make sure the fuel injection and timing is correct for the new engine while running on the ecu for the smaller engine. Just flash it?

Yup. Not a lot of details on how the engine was installed...however the fact that this mechanic recommends changing a diff in connection with this problem would probably make me take this car somewhere else

My question would be how the ECU detects wheelspin. I would think the ECU and/or TCU compares flywheel speed to some other sensored drive component down stream. If you overlay this with the changes made, the source of the problem will be nearby.

The ESP looks to the SAS & wheel rotational data from the ABS sensors. (Plus Yaw sensors etc.)
I would start by checking every harness connector you disturbed & giving it a clean with switch cleaner. Check the main ESP connector. The ESP unit is mounted on the face of the ABS block. Reset the SAS by turning the steering from lock to lock 5 times.
Good luck.

no this does not happen on every gear, only the gear that i start from.
this is on manual shifting and automatic as well.
i will go and check another opinion and take everything here into consideration.
by the way, did a change to the MAF, installed another used one and a new BOSCHE one and the issue still persisted.
but one small thing, the ESP kicks in after the engine takes of at around 4000 RPM.
when the issue is happenign the triangle is not flashing.. how can it be that the ESP is kicking in?
sadly, dono what happened to my cluster, cannot access dyno mode..
my cluster works by pushing it for like 30 or 40 seconds to get access to dyno mode, not working.. also did a 3 click on the reset and nothing happened as well!

Sorry for bringing up an old thread. I seem to have an issue with blue smoke on start for about 2 seconds or so. This appeared rather suddenly, three days after doing an oil change a while back. Googling brought me to this thread, and the above quote mentions a oil drain hole that can have a cast skin. None of the links work for me, returning a 404 error. Could someone possibly point me in a direction as to where this oil drain hole with a cast skin is situated? I have a 1998 model W210 E280 fitted with a M112 engine. I might also add, car has terrible gas mileage and a rather weird smell out the exhaust. By the way, its def blue smoke.
