Re: ignition help
When i have questions like that, the first thing i do is look up the -part number- for the two years/models in question. Any Sprinter repair shop should be able to provide them.
If they're the same, then it will fit.
Here in the US we don't get the range of Sprinter models other countries have access to, so i'm limited to the "easier" question of "does a 200x widget fit a 200y?" (x and y being numbers from 1 thru 8)
US part number documents are available from
http://www.berrysprinter.com/sprinterparts.php
I would -assume- that model year 2002 thru 2006 are the same ignition barrel.
good luck
