Will this fit my Audi A4?
Yes — this retainer fits the Audi A4 from 2002 through 2008, covering the B6 (2002–2005) and B7 (2006–2008) generations. It secures the splash shield, fender liner, and engine cover panels.
Does this fit VW Passat?
Yes — the VW Passat (B5/B6, 2002–2010) uses this same slotted-head retainer for splash shield and underbody panel attachment, sharing the VAG platform fastener design with Audi models.
What does a slotted-head retainer look like?
A slotted-head retainer has a flat head with a single straight slot, similar to a flathead screw slot. This allows installation or removal using a standard flathead screwdriver while still pushing into the panel hole like a push-type clip.
Does this also replace 4A0-805-121-A?
Yes — this retainer cross-references both 4A0-805-121-C and 4A0-805-121-A. The "A" and "C" suffixes indicate production revision levels; the dimensions and function are identical.
Does this fit Skoda vehicles?
Yes — the Skoda Superb (2002–2008) shares VAG platform components with the Audi A4 and uses this same part number for splash shield and undercarriage panel retention.
