Workshop storyParts guidance
Why the correct replacement part may carry a newer number.
An electronic parts catalogue can show when a manufacturer has formally superseded an older component.
The workshop record
A different part number does not automatically mean the wrong part.
Vehicle manufacturers can discontinue an earlier component and designate a newer one as its replacement.
That change should be verified through the relevant electronic parts catalogue rather than assumed.
The work
Check the catalogue's supersession trail.
The workshop guidance points to the catalogue record that marks an older part as dropped and replaced.
This article explains the verification principle; it does not claim that every alternative part number is interchangeable.
What this record confirms
Supersession is a manufacturer-documented parts relationship.
The source confirms that electronic parts catalogues may identify newer designated replacements for discontinued older parts.
