The part number I'd like is: A0018303484. This seems to be the Duovalve from everything W202 wise apart from a C250TD and C220CDI.
The one to fit a C250TD or C220CDI is: A0018303684 . This is £100 more expensive than the other on the Inchcape site. I'm trying to work out what the difference is between the two valves.
