Summary
Complaint Noticeable vibrations at the steering wheel: • At speeds between 40mph and 75mph • On straight stretches of road and in long corners • With driver assistance systems switched on Cause Control oscillations in the electric power steering. Remedy Perform software update of electric power steering (N68). Note: Please ensure newest Xentry release software is installed and all addons are updated. After the software update, teach in the steering limitations of the electric power steering again: 1. Start engine 2. Turn steering wheel all the way to the left and briefly hold at the steering limitation 3. Turn steering wheel all the way to the right and briefly hold at the steering limitation 4. Perform a test drive in which you drive at approx. 5-10 km/h in an "8" shape, alternately turning the steering wheel to the steering limitations on the left and right. If vibrations can still be felt following the software update: 1. Connect XENTRY and select control unit N68 - Electric power steering (ES) 2. Switch to the "Adaptations" menu item, then under the "Teach-in processes" item, run the "Special function" in full. With this function, parameters of the software are adapted to reduce vibrations in the steering wheel. If vibrations continue to occur in the steering wheel despite this action, please create a TIPS case.

Summary
In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA, LLC ("MBUSA") is extending the warranty coverage on the HV Refrigerant Compressor & Condenser in certain Model Year ("MY") vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/150,000 miles, whichever occurs first, due to the following condition: The copper wire winding in the HV refrigerant compressor might corrode over time and could cause the battery management system to diagnose a lower insulation resistance leading to an insulation error. Due to the physical connection of the HV refrigerant compressor to the HV electrical system, the insulation error would trigger a fault in the entire HV electrical system. A warning message may be displayed (e.g., battery symbol with text malfunction, without restarting engine - visit workshop, towing prohibited see owner's manual) in the instrument cluster. Both electric and combustion engine driving is possible. However, if the driver ignores the visit workshop without restarting a message and switches off the vehicle, it would no longer be able to start.

Summary
Fault code P06DA00 is found current or stored in engine control unit. Check engine light may be activated. Various causes Up to Model year 2018 Fault code P06DA00 can be disregarded if not activating the check engine light, unless otherwise specified in the guided test. The vehicle continues to operate as designed. Further causes should be investigated if complaint of check engine light is received. If fault code P06DA00 is activating the check engine light, update software of the ME control unit. No further repairs needed if the code no longer activates check engine light after 2 drive cycles. Model year 2019 and later Fault code P06DA00 will activate check engine light as of model year 2019. No driveability concerns will be observed, only illumination of the CEL. This fault code indicates high resistance or open in the circuit to Y130 oil pump control valve. Perform guided test for component Y130 under list of tests in ME. Diagnose location of high resistance or open in Y130 circuit and repair as necessary. Warranty claims submitted without supporting guided test results may be subject to debit.

Summary
In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA (âMBUSAâ) is extending the coverage for the intake line assembly on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years / 150,000 miles (whichever occurs first), and applies to the vehicle regardless of ownership. Why the warranty extension? On certain Model Year 2015 - 2020 C/E/GLC/SLC and SLK vehicles, under certain circumstances, the partial-load ventilation valve (a part of the intake line assembly) may not work as intended, resulting in the illumination of the check engine Malfunction Indicator Lamp (âMILâ). A faulty partial-load ventilation valve might also increase exhaust gas emission. . Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. â¢ If your preferred authorized Mercedes-Benz dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be performed at no cost to you. â¢ This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet. We hope you are enjoying your Mercedes-Benz vehicle and we apologize for any inconvenience this may have caused.
