Hello, ref: Ml350 camshaft solenoid leak! I am seeking out for your help wrt to a situation with 2012 Ml350. Enclosed herewith is an inspection report from a recent service visit requiring close of $8k in repairs for your reference. Engine harness (oil �lled harness and various components have oil in them, all components with oil should be replaced, quick insp found a few components but there may be more that need to be replaced) after reviewing the inspection report, I did some research and came across campaign no. 2012070002, September 2012 (copy enclosed for your reference), wherein mercedes had identified it as a part of recall and service campaign and agrees to cover the cost and labor damages to any downstream components due to the camshaft solenoid leak. This service campaign has been initiated because daimler ag (dag), the manufacturer of mercedes- benz vehicles, has determined that due to the settling properties of the seal, oil may leak from the camshaft adjustment solenoid. Dealers will retrofit four adapter harnesses onto the engine wiring harness as a precautionary measure at the next workshop visit. Please note that recall and service campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator. Approximately 557,108 vehicles are affected please review and let me know if you have any questions. Mercedes is not owning the responsibility for repair. Appreciate your help in this regard.
