I just thought that I would raise this here with you guys in case you are having similar issues.

A few of our AGOA members with G350's are experiencing some problems and a few are having the entire engine replaced due to catastrophic failure or damage. There seems to be a limited recall (service measure 1003) so it must not impact all models but it seems that with the recall they are replacing the sump which anecdotally is too small and causing the oil to overheat. The trouble with the sump fix is that what damage has already been caused?

I know very little else about it but if you have a G350 it might be worth approaching your dealer about this issue.

I cannot find this reference - a typical service measure number is "SM42.50-P-0002A". Try and get the exact document title , thanks

I have Just been informed that it is Service Measure SM 1003 Code:1204P01A81

Title is Check Engine Oil Quality and modify Engine.

Depending on the severity of the issue either modification and/or replacement of the engine may be necessary.

This is very interesting. I have a 2011 G350 with the smaller oil tank and when I questioned my dealer and then MBSA about the issue/recall they denied all knowledge. What should I do now?

Take it up with MB Germany, colleague of mine got a Very quick response from MBSA after going that route. It was on C-Class though. Thats after getting no joy from MBSA and local dealer.

why do Australia get looked after and we dont???
I don't think it is a matter of Australia getting looked after - I think that this issue came about because of a catastrophic engine failure on an AGOA member's G. It took MB a long while to determine the cause and now they have implemented this 'service measure' to increase the sump capacity from 9L to 14L and assess the level of sludging in the sump while doing this. Depending on the severity they are either:

  • Just bolting the modified sump back on; or
  • Replacing Crankshaft Bearings;or
  • Replacing the engine.
In all RHD vehicles they also modify the Drag Link and Auto Cooler lines to accomodate the revised sump.

The vehicles that I know of that have had, or are having engines replaced have done 30,000 and 18,000 kms repectively.

I would guess that MB are dealing with this issue in Australia where it was initially found and I would also guess that they would be looking at a longer term solution for other markets.

I would be pushing your dealer to find out more about it.

When they book you in for this service measure here; they tell you to expect about 2 weeks and give you a loan car.

I am hopefully attending a sump removal after Easter so I might be able to report more then. Don't wait for them to contact you, This service measure should be on their computers now.

Hi Peter,

Both vehicles had light - mainly highway use. No heavy off road and no heavy towing.

Both owners have been struggling to get a reasonable explanation of why this problem has occurred and why it seems to effect some vehicles more than others.

I assume the oil's used where factory / dealer supplied and no mucking about with the vehicles computer to make it "go faster ".

Hi John

Thank you very much for the detailed information. My car has done 18K so I guess I'm in the zone. The service manager at the dealership laughed it off (no surprise there as he also laughed off not filling the Adblue on it's first service and the vehicle not being able to go on a trip). MBSA also flatly denied any service notice and when I pressed them they said any damage done would be my fault! Not quite sure how that works as it's on a motorplan.

I'll send an email to Germany and cc MBSA.

This is not what I would expect from MB.

Both are obviously near new vehicles and have been serviced by dealerships only with no modding on either vehicle - obviously MB would not be replacing engines under warranty if they believed that the owners were at fault and likewise they would not be modifying all vehicles if they did not believe the problem to be systemic.
