Hello MB World!
Is it possible for me get hold of my car's actual km reading? I'm suspecting it has been rolled back?
Car has driven 138.000 km and check engine lamp came on. Limp mode, max 3000 rpm, Y74 pressure regulator code up. MB says that the pressure regulator that is mounted on is not original part??
Is it also possible for me to get all the services registered at MB as I have already an incosistency after contacting the MB that the car is supposed to have been in?
VIN:WDB2110071B131194
Thanks a lot in advance.
Cannot provide service history or assist with roll back, attached MB data card. MB service history is called Vehicle Master Inquiry, request VMI (dealership discretion to provide hardcopy). Y74 OEM is incorporated into fuel distributor MB does not list separately attached correct part # if it’s your intent to replace.

Thank you so much for the quick and informational reply.
I see.
Just to paint a picture of the case.
I am going for reclamation. Seller (dealer, not MB) has withheld information, critical for me and the car, and I have documentation to what I believe to be proof.
The thing is, I live in Norway. Legal terms are so important and jurisdiction is an issue I am well aware of. This is why this is so difficult. It gives the possibilities for loopholes to exist an taken advantage of. Someone with good computing and technical skills can manipulate so much for purpose of profit, meanwhile the owner is next to powerless to prove anything.
Anyway, I have a MB report that says the part mounted is not original, isn't that a factor? How can I have changed the part at some point after 97500km, and it broke again at around 137000? I maintain my cars myself, but I do know my limitations, so when it comes to big stuff, I ask for help. I have proof of all parts that I have changed myself. Wear and tear, calipers, breakpads, oil services, v-belt and such. When this came, I run a diagnose myself to see what's going on. After that it went to MB. After they reported about the part I've figured out from previous EU-checks (every other year mandatory check on the car for road safety) that ABS module has been replaced/fixed. The car had also a leak at the oil separator crankcase. Seller said they propably just spilled a little from last service. Lots of other inconsistencies as well.
Sorry for taking your time for this.
Now if I can ask your professional help again.
Could there be connection between no oil service in a long time before my buy (15months ago) and the leak in the oil separator, and then that affecting the pressure regulation valve/rail?
Again, your information is so much appreciated. Thank you.

Yes, if OS is left untreated it can result in damage to the engine. When the air-oil separator is not working properly, it cannot separate the oil from the “air” that it is sucking back to be combusted, and oil is pulled into the intake manifold. Worst case scenario, see attachment.

PRECICELY!!!! What other mechanics write as well!! The way you explain car mechanics though...to be admired.
The document you provided for measuring cylinder bores (worst case scenario that you are mentioning), is that what will happen if pressure regulating rail gets fixed, but not the oil separator?
And also, just to clarify it for me who is a DIY-er. What you are referring to as worst case scenario, is that the fuel injectors getting ruined??
WCS - referring to oil separator, cylinders should be proactively checked. Yes failing regulator can, of course, cause problems to to fuel injection system.

I see. Am I understanding correct that MB actually should have done a proactive check on the cylinders when they reported about the failing regulator?

Hello again. Sorry for the quiet period but these cases take time. I would like to ask if I may:
1. What happens if the oil service is not performed for around 42.000km (59.000km-101.000km interval) and then performed at 101.000km, and again at 124.000?
2. What can cause a leakage to the Oil Separator?
3. Could you please explain one more time what the attachment here is suggesting as worst case scenario if OS is faulty and left untreated?
MB says that they don't see that the leakage in OS can cause the pressure regulation valve to fail.
Again, many thanks umin advance for your ti.e and effort.
