DME relay part no. difference
- Thread starter poorleno
- Start date
I think the last digits refer to the part's updates/modifications. So your existing relay is a 'first series' one, whilst your new one is a 'second series',so will be absolutely fine.
I've just checked, I have exactly the same situation. 00 in car 01 in door pocket!

Both are the 993 part.
The 01 will most often relate to a new supplier.
In general (not cosmetic parts, because it's the colour), the digits after the 3x3 (000.000.000) is irrelevant.
The part number defines its specification.
Short answer: they both work (and both are the more reliable design).

My understanding is that the last digit relates to any update of the part. This can be a change of supplier as said, but can also refer to a specification change.
Case in point being the CL Controller. 928.618.260.03 has a different operational spec to prior variants. Same manufacturer and appearance.

It can be made differently (including changing materials).
It can have a different supplier.
It can't change operational spec.
ie it must always do the same thing (and be physically identical in terms of mechanical or electrical connectivity etc).
The last two digits only indicate if there has been a non-functional change.

In the case of the CL controller .03 has the ability to pop the central locking when the interior door handle is operated. .00 works in every other respect the same, but does not have this feature.
So, I stand by my understanding that as the parts are updated or improved. The PN last digit is increased.

But PN 03 still has the same functions as PN 00 and does them exactly the same.
From the point of view of PN 03 however, PN 00 does not do the same as PN 03 though.
The issue is "the ability to pop the CL ..." in this case is a side effect of using a supplier with as shared component to another model or marque (which does spec and use that capability).
The primary spec (00) is still retained.
There are also instances (996 climate control module for example) where non-primary functionality is lost in later revisions, but is still within spec in later revisions.
Access or use of non-primary spec functionality should really be regarded as a hack (and is not guaranteed at the next revision/supplier change).
Perhaps I should have described it as a minimum acceptable spec.
