If you are reading this you may have been irritated by the huge number and range of methods described to reset the service indicator (ASSYST) on the 2008 (or thereabout) 111 Vito (W639). Most of the methods described on the web, in the most part, offered by well-meaning people who have incorrectly read or copied the incorrect information from somewhere then relayed it via a post on a forum to someone asking for help. The truth is, there are a few dashboard/instrument cluster versions in the W639 range and it changed version in this year for the basic van (single semi circular speedo to twin circular dial) – most get it wrong and to find the correct method for resetting with this twin dial type of dashboard without steering wheel controls, is rare to find and at the very least may prevent you some irritation by having to try method after method finding that they simply do not work!
So here it is: If you have specifically a 2008 Vito 111 (W639) and your instrument pod is like this one below, with no steering wheel control buttons…..
