I recently had a B6 service performed on my C350E Estate and asked that the they look at the aircon as it was blowing out hot air and mentioned that a red battery warning light had appeared on the dash. They did the B6 service, replaced the main and the auxiliary batteries, and told me the system was reporting the error "P142800" which is "There is a vehicle side insulation warning in the hybrid/high-voltage on-board electrical system". They showed me the US recall notice https://static.nhtsa.gov/odi/tsbs/20...53707-0001.pdf (attached) which states (in part) " 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..."

In order "to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers" MB USA will replace the compressor at no cost and extend the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/150,000 miles.

This would seem to be an appropriate response in line with the stated objective. However, MB Australia, as reflected through their dealer network, who either do not wish to assure the proper performance of Mercedes-Benz products or to enhance the satisfaction of their customers, do not recognise this problem. I have read suggestions on launching a class action, but am wondering have other Owners experienced something similar and if so, how did they go about getting it resolved?
