The air flow sensor on my 1987 MB 260E Euro version is busted and needs replacement. Already found a brand new replacement but I noticed that the black box attached to it has a different part number. The black box is the electronic part located at the side of the air flow sensor with the outlet for the plug. The busted one has a 3430 591 017 part no. while the new stock has a 3430 591 034 on it. Would this be a problem for me. I was thinking that maybe it's just a new part number for this item.

Urgently needs help.
