FAQ
Q: Does this fit my 2015 VW Golf TDI?
A: Yes. This filter fits all Mk7 Golf models (2015-2018) including TDI, TSI, GTI, and e-Golf. Same part across all powertrains.
Q: Where is the cabin filter located on a Mk6 Jetta?
A: Under the passenger side dashboard, behind a foam cover. Remove the cover (2 plastic clips), slide out the old filter tray, insert the new filter with the arrow pointing toward the passenger seat. 5-minute job.
Q: How do I stop the musty AC smell in my VW?
A: Replace the cabin filter (condensation on a dirty filter breeds mold), then run the fan on high with AC off for 5 minutes after driving to dry the evaporator. An anti-microbial cabin filter like the CUK 2939 helps prevent recurrence.
