Hi,

Hopefully someone can help me, im looking at buying a can filter for correcting mileage on a 2007 S320 W221. I see there are 2 options one which needs cutting wires and soldering and the other which seems to just connect between 2 connectors.

Im interested in the plug in solution but cant seem to find any instructions, does it just plug into the back of the speedo and then thats it? Can mileage be changed just once with this?

Thanks in advance
