A mechanic cannot determine the correct rear rotor size for a 2012 Jetta Sportwagen because aftermarket fitment guides list two different sizes (253mm and 272mm) as compatible, creating confusion and risk of incorrect part selection.

Existing fitment tools provide ambiguous results by listing multiple sizes as compatible without clear guidance on which is correct for the specific vehicle configuration, forcing mechanics to rely on memory or physical measurement of old parts.
