  Summary

  Complaint Engine vibrations perceived at low rpm. Fault codes for the camshaft position of the intake camshaft (P001100, P001104, P001200) or exhaust camshaft (P001400, P001404, P001500) may be stored. Cause Continuously fluctuating oil pressure in the central valve may lead to damage to the filter screen on the central valve. This can result in damage to the filter screen or the filter screen breaking loose. The resulting loss of oil pressure prevents proper adjustment of the camshaft adjuster. If the filter screen breaks loose, parts of it may settle in the camshaft adjuster or in the camshaft. If there are parts in the camshaft, they can pass through the oil supply bore to the last camshaft bearing (i.e., the first camshaft bearing behind the adjuster) and cause damage there. Remedy 1. In cases in which only the screen of the central valve is damaged and no metal particles are found in the oil filter, the following parts must be replaced: - Always both central valves - The camshaft adjuster of the damaged central valve 2. In cases where the screen is completely missing and metal particles are found in the oil filter, the camshaft bearings must be checked. If any damage is visible there, proceed as follows: - Both central valves - The camshaft adjuster of the damaged central valve - The camshaft bearing housing (camshafts are already included here) - Oil change with oil filter

  Summary

  Complaint Only vehicles with a variable transfer case are affected. This can be identified through control unit N45 or N15/7 in the quick test. When accelerating with light load, vibrations or jolting sensation may come from the drivetrain. It may be mistaken for a harsh shift. Cause Modified oil quality of the transfer case over time Remedy 1. Check initial quick test for faults in the following control units. N45 or N15/7 - All-wheel drive (ARS) N127 - 'Drivetrain' (PTCU) control unit Y3/8 - Transmission control for 9-gear transmission (VGS) N3/10 - Engine electronics for combustion engine If faults are present: Process them as per the guided test in Xentry. If no faults are present: 2. Check the transmission oil level If the oil level is correct: 3. Unplug the connector for the transfer cases control unit and reassess the vehicle on a subsequent test drive If the complaint no longer occurs with the control unit disconnected: 4. Perform an oil change of the transfer case according to WIS specifications - Collect an oil sample of the original fluid 5. Complete all transfer case Tech-in processes located under VG Control Unit > Adaptations - Resetting the oil service data - Calibration of N15/7 5. Perform road test of vehicle to bring transmission to operating temperature ( >60C ) 6. Operate vehicle in full circle with steering at full lock - 5x to the left - 5x to the right Return the vehicle to the client and request they drive the vehicle for at least 200 miles and return if the concern is not resolved. The extended drive will ensure the clutches are properly conditioned with the new oil and should resolve the concern. If the concern continues to occur with the control unit disconnected or after the above steps have been performed, please submit a TIPS case to the Powertrain inbox with the following information: - Initial quick test with fault freeze frame data - Initial transmission EEPROM data - VGS and Transfer Case Control Unit Log (N45 or N15/7) - Photo of the original oil condition - What color was the fluid drained from the transfer case before the oil change? - Was an oil sample collected, and can you provide a photo of the original fluid? - What color and part number fluid was used during the oil change? - How far was the vehicle driven after?

  Summary

  Complaint -Check engine light illuminated. -Engine runs rough. -Poor shifting or jerking when accelerating. -Fault codes stored related to mixture formation, injector quantity adjustment, or misfire. Note: One or more of the above symptoms can occur. It is possible that no fault codes are stored. Cause Leaking valve seat in cylinder head. Remedy -Perform cylinder leakage check as noted in WIS group 01.00. If excessive leakage is found determine if leak is from intake or exhaust valves. -If leakage is found from intake or exhaust valves, remove cylinder head and inspect valve seats. -The complete cylinder head must be replaced if valve seat damage is found. The valve seats can not be reworked. -Engine oil and filter should be changed after the repair. Workshop notes cylinder head repair: 1. The intake rocker arm roller is narrower than the exhaust and they must not be interchanged. Mark the rocker arms so they are reinstalled in their original location. 2. Inspect all parts that are being reused (i.e. camshafts, rocker arms) for signs of wear or damage. See WIS doc AH05.20-P-1000-09SZ for examples of normal and abnormal wear. Replace parts with new if damage or wear is found. 3. Check that all rocker arms are correctly located on the camshaft before installing cylinder head cover. Rotate engine at least 2 times and check that there are no problems with rocker arms. 4. The timing chain tensioner can be reused if it extends fully, has no noticeable problems in prior operation, and no chain drive components were replaced. 5. Care must be taken when removing fuel injectors to prevent damage. See WIS doc AR07.03-P-0004-03MM. 6. Cleanliness must be observed during repair to prevent subsequent complaint or engine damage:• When cleaning engine block surface, ensure oil ports are sealed to prevent debris from entering oil circuit. Refer to SI01.40-P-0010A. • No abrasive materials, sharp-edged tools, or unapproved cleaners should be used on engine block surface. Refer to AR01.00-P-0050-01A. • Any debris from cleaning that has entered the cooling jacket should be removed before assembly of engine.

  Summary

  Dear Mercedes-Benz Owner: In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA is extending the warranty coverage on the exhaust valve system in your vehicle from the original New Vehicle Limited Warranty of 4 years/ 50,000 miles to 15 years/ 150,000 miles (whichever occurs first). This applies to the vehicle regardless of ownership. On certain Model Year 2018 - 2023 C-Class, E-Class, GLC and GLE vehicles with the 4-cylinder engine "M264", over time, the exhaust valve system might not continue to work properly and result in an engine misfire and potential illumination of the check engine Malfunction Indicator Lamp ('MIL'). Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. •If your preferred authorized Mercedes-Benz dealership performs diagnosis and confirms that your vehicle meets the criteria for this extended warranty, the repair will be covered at no cost to you. •This extended warranty does not apply to any other components or conditions beyond the ones described under this extended warranty, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.
