I substituted the Bosch part in my C240 with the Pierburg part from my straight six S320 cdi to diagnose poor running problems!

I am a little confused as to using the Pierburg MAS as a replacement for the original bosch part.
The Pierburg part number is listed as 7.22684.07.0
According to Pierburg this is a replacement for their own unit part number 7.22684.00.0

The "how to" suggests that this is the replacement for the original Bosch fitment in the M112 V6 engines part number A112 094 00 48 however the Pierburg pdf states that this is a replacement for the A611 094 00 48 which is actually the OM611 diesel engine. Note that the last seven digits are actually the same, the first apply to the motor code!
Funnily enough if you search for the German and Swedish part number (18789) on their site it gives the Pierburg component as the replacement for a Seat Ibiza diesel!!!
I HAVE actually replaced my original Bosch sensor in my C240 V6 with the Pierburg unit and it seems to work fine. Are the diesel and petrol MASs the same in real terms? It would appear to be so!! Sorry about all the confusing part numbers but it would appear that Pierburg DO NOT actaully make a direct replacement for the M112 engine as described in the "How to" although it actually seems to work
