OEM Part Number: 5Q0819669

Accuracy note: this part is genuinely consistent across the MQB platform range, since it's part of the HVAC system rather than the drivetrain.

Standard particulate filter	Ateca OEM: 5Q0819644A — shared across the MQB platform range including Golf, Tiguan, Touran, T-Roc, Karoq, Superb, Ateca, and A3/Q2/Q3
Activated carbon/charcoal filter	Ateca OEM: 5Q0819653 — a genuinely different filter media from the standard version, not just a branding variation; confirmed both are fitted across the same MQB range depending on original spec
Current combined reference	Ateca OEM: 5Q0819669 is commonly listed as a combined/superseding reference for either type — check which specific filter your car has fitted rather than assuming from the number alone

A Genuine Warning: Even Official Guides Can Be Wrong for Newer Models — Seat Ateca Cabin Air Filter

Worth knowing before following a generic guide: access location and method has genuinely changed between generations on this platform, and it's not just owner confusion — even official manufacturer installation documentation has been confirmed incorrect for newer models in at least one documented case, where a Mann Filter installation guide correctly described the process for an older Ibiza generation but was flagged by multiple owners as simply wrong for the newer, post-2017 model. Older models (broadly pre-2017) are typically accessed behind the glovebox, secured by a small rectangular cover with a few screws; confirm you're following a guide specific to your actual generation before assuming a general "SEAT Ibiza" guide applies.

A genuine, specific spray treatment worth trying for a musty AC smell: a documented, well-corroborated method involves fitting a fresh filter first, then placing an in-cabin AC system treatment canister (such as a Kleen-Air or similar biocide spray) on the back seat, running the fans on full speed with recirculation on, and letting the can discharge fully before continuing to run the fans for a further period. This treats mould and mildew built up through the evaporator and ductwork, not just the filter itself — genuinely worth trying before assuming a fresh filter alone hasn't fully solved a persistent smell.

Seat Ateca Cabin Air Filter: Easy to Forget, Easy to Fix

On the Seat Ateca, this part sits in an unusual category: neglecting it changes nothing about how the car drives, so there's no natural prompt to replace it. It only affects the air you're breathing inside the cabin, which is why it's so often left well past its interval.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

Seat Ateca Cabin Air Filter: What It Does

Every bit of air blown through the Seat Ateca's cabin vents passes through this filter first, which is what traps dust and pollen — plus some odours and pollutants if it's an activated-carbon type. It has nothing to do with the engine air filter, a wholly separate component built for the combustion side of things.
