Good day
My 2001W220 S600 seems to be running fine so perhaps I should leave well alone but... I used my OBD II just to see if anything came up and I got the following message -
Fault code P208F, Y81/1 (Cylinder shut off valve for cylinders 10-12) electrical fault.
I've tried to do some research via Google but can't find anything useful. I spoke to a local MB Independent who said it was probably to do with the system of shutting down cylinders when at a steady speed to save fuel and that he could use his computer to disable that function. I'm not sure though, the problem only relates to 3 of the 12 cylinders, does anyone recognise this issue and have any advice for me?
Thank you
Geoff
