If you receive customer reports in the above model vehicles of the oil level warning message frequently appearing in the instrument cluster, "Oil
level too low" or "Check Engine Oil Level at Next Service Stop", but the oil level is correct on the dipstick, there could be several causes depending
on the vehicle. This document is a consolidation of those possible causes.
1. Model 203.087/092 and 211.087/287, Equipped with M272 - Erroneous IC Warning Display "Check Engine Oil Level at Next Service Stop":
Oil level warning message frequently appears in the instrument cluster, however the oil level correct on the dipstick, the cause may be the
incorrect oil data record stored in the ASSYST control unit (Model 211), or instrument cluster (Model 203). To resolve, perform the following
procedures.
Message:
"Pour in one liter of oil at next refueling stop" (Model 211 4MATIC with M272 up to 6/2005) "Check oil level at next refueling stop" (Model
211 4MATIC as of 6/2005 and Model 203 4MATIC with M272 as of production startup)
1a. Adaptation of Modified Oil Data Record with SDS 10/06 or Later
Model 203 4MATIC with M272 Engine, up to VIN F886321: Control Units -> Information and communication -> ICM - Vehicle code 12
/ NO -> CU adaptations -> select code 807 -> select national version select M272 all-wheel drive change status 3 "or higher" confirm
selection.
Model 211 4MATIC with M272 Engine, up to VIN X218820
- Check whether CGW programming is possible by using SDS: Control units -> Body -> CGW -> Control Unit adaptations -> Control
Unit programming. If yes, perform control unit programming and then perform parameterization in ASSYST. If no, perform
parameterization in ASSYST.
- Perform parameterization in ASSYST by using SDS: Start Control -> Units -> Information and communication -> ASSYST -> CU
adaptations -> select engine M272 -> Select national version -> Select engine for ASSYST M272 Model 211 all-wheel drive "National
version" status 5 or higher.
1b. Check Oil Dipstick Marking on Handle (Model 203 / 211 up to Engine No. 2729..30467144)
NOTE: As of February 2, 2007, Section 1b of this DTB must not be performed on the following vehicles which are covered under
Service Campaign No. 2007010010
Model 203.087 - Serial Nos. AF725595 to F864624
Model 203.092 - Serial Nos. F725472 to F885088
Model 211.087 - Serial Nos. X177825 to X219293
Model 211.287 - Serial Nos. X174229 to X219226
Combining step 1b with the above referenced Campaign will result in a charge back of step 1b.
a. Oil dipstick with marking 27214 is correct.
b. Oil dipstick with different marking should be replaced with part number A272 010 14 72.
c. Check whether quantity of engine oil in engine corresponds to specification in WIS.

2. Model 164.186 - Erroneous IC Warning Display "Check Engine Oil Level at Next Service Stop" Confirm engine type coding in ASSYST
using the current issue of SDS: Control unit -> Information and Communication - ASSYST Active Service System -> Control Unit
Adaptations -> Engine Type - Code to correct engine type.
3. Model 164.871 - Oil Level Too Low Displayed In Instrument Cluster: Initial oil level too low, perform the following applicable corrective
measure.
3a. Vehicles Up to VIN No. A213990 / Production Date 12/20/2006 - Check and correct oil level where necessary by adding 0.3 liter oil at
PDI or at the customers "1st Visit" for all newly sold GL450 vehicles. Refer to WIS document AP-18.00-P-0101GZ. Costs are to be
charged using the warranty code 00001 70.
3b. Check Oil Dipstick Marking on Handle - Oil dipstick with marking 27314 is correct. Oil dipstick with different marking should be
replaced with part number A273 010 14 72. New specification for quantity of engine oil in engine is 9.0 liters with filter change.
3c. Vehicles with VIN No. A213991 up to A235524 / Production Date 2/9/2007
NOTE: Do not automatically add 0.3 liters of oil; check dipstick first.
Oil dipstick with marking 27314 is correct. Oil dipstick with different marking should be replaced with part number A273 010 14 72. New
specification for quantity of engine oil in engine is 9.0 liters with filter change.
4. Model 221.186, Equipped with M273 Engine and 4-Matic, Erroneous IC Warning Display "Check Engine Oil Level at Next Service Stop" -
Update oil data record in ASSYST using SDS: Control unit Information and Communication ASSYST Control Unit Adaptations SCN coding
Perform SCN online coding Work through steps 1-3 in SDS to perform SCN coding.
5. Model 209/211/219, Equipped with M156 Engine, Oil Level Warning Message "Add 1 liter engine oil at next refueling stop" or "Check oil at
next refueling stop" in Instrument Cluster / Oil Level on Dipstick is OK - Perform the following steps.
a. Check the coding of the engine model designation and oil data set of the ASSYST control unit in SDS -> Control units -> Information and
communication -> ASSYST -> Control unit adaptations -> Engine type -> Engine type M156 E63 Version for rest of world Status: 3 has
been recognized -> Information and communication -> ASSYST PLUS -> Control unit adaptations -> Control module reset
b. Check installed oil dipstick and replace if necessary. The correct oil dipstick is identifiable by the red handle and by the code 156 16
(previously 156 12 or 156 14)
c. Check oil level and correct if necessary.
6. Model 164.122/822 (up to VIN A261645) and 251.122 (up to VIN A059019), "Check oil at next refueling stop" Warning in Instrument
Cluster - If you receive customer reports that at speeds above 75 mph the instrument cluster displays - Check engine oil level at next refueling
stop, the cause may be the position of the oil level switch.
NOTE: Condition only relevant when the oil level is significantly above "min".
a. To resolve, install a lengthened bracket (7 mm) for the oil level switch (part number A642 018 27 40) and check software in the Central
Gateway. For Model 164 vehicles, the data records in software version 30A9 (and higher) are OK and for Model 251 vehicles, the data
records in software version 30AA (and higher) are OK. SDS path: Control units -> Information and communication -> ASSYST ->
Control unit log. The software description in the ECU control unit log from ASSYST (not ASSYST Plus). In the Line "Variant code", the
first 4 characters "00 01..." gives you the information on the above mentioned software (Figure 1). If the software is incorrect, look for the
latest software with DAS.
b. Replace the oil level switch as per step 7.
7. All Passenger and Light Truck Models, Equipped with Engine M156, M272, M273 or M642 (Up to engine no. 642 xxx 40 673486), Faulty
Oil Level Switch - If after performing the applicable remedy(s) 1 through 6 stated within this document, the issue has not been resolved, the

cause may be a malfunctioning oil level switch. Perform the following.
a. Check the oil level using the dipstick.
b. If the oil level is confirmed between the "MIN" and the "MAX" marks on the dipstick, replace oil level switch with part number A001 153
11 32 as per the applicable WIS document.
NOTE: For Engines M272, M273 and M642 - If there is any deformation of the stamped steel bottom section of the oil pan after
removal, it must be replaced. Refer to EPCnet for applicable part number.
c. It is possible to install the switch upside down. For correct installation refer to Figure 2.
