Mercedes GLA220 Diesel X156 Filters: Oil, Air, Fuel & Cabin

MANN lists HU 7010 z oil filters and C 22 020 engine air filters for its selected GLA220 CDI and GLA220d X156 OM651.930 applications. For the fuel filter, right- and left-hand-drive entries differ. Cabin-filter options also need their complete references checked.

This guide covers the catalogue’s GLA220 CDI types 156.903/156.905 at 125 kW/170 hp and GLA220d X156 at 130 kW/177 hp. Check the engine and output before ordering. It is not a parts list for the petrol GLA220, AMG GLA45 or later H247 diesel.

Oil filter and engine air filter

Filter	MANN reference	Buying check
Engine oil	HU 7010 z	Match the selected OM651.930 application.
Engine air	C 22 020	Confirm diesel application and output, rather than the GLA badge alone.

The manufacturer’s current product pages list these GLA diesel applications independently. Similar-looking boxes or a retailer’s general “GLA service kit” title are not enough: read each part number in the pack.

Search Amazon for MANN C 22 020 air filters

This searches Amazon for C 22 020 air filters. Check the actual result before ordering because searches can include unrelated products. The GLA220d oil guide covers approval and capacity; sharing an oil filter with another Mercedes does not establish the same oil-fill quantity.

Fuel filter: choose the correct steering-side entry

The MANN catalogue separates WK 820/15 for right-hand drive and WK 820/14 for left-hand drive in the selected GLA220 diesel entries. The current WK 820/15 product page specifically lists the right-hand-drive GLA applications.

A UK-market car is a reason to pay attention to that distinction, not a reason to skip checking it. Match the actual steering layout, including for imports, and have the supplier confirm the complete application. A fuel filter selected for another GLA engine should not be substituted just because it has a similar name.

Cabin filter: CUK or FP?

Reference	MANN description	Application detail
CUK 26 007	Activated-carbon cabin filter	Listed for the selected X156 diesel applications.
FP 26 007/1	Biofunctional cabin filter	Specifically listed for right-hand drive.

Search Amazon for MANN CUK 26 007 cabin filters Search Amazon for MANN FP 26 007/1 cabin filters

These are alternative main cabin-filter options to assess, rather than an instruction to fit both. Retain the /1 when selecting the right-hand-drive FP reference: MANN separately lists FP 26 007. Its FP 26 007/1 page identifies the mounting area as beneath the glove compartment in the passenger area; consult the complete applicable fitting instructions before removal.

Does a service kit tell you what is due?

No. The catalogue establishes parts applications, not the replacement schedule. A kit containing several filters does not prove that every one is due at the next service, and an A/B suffix does not validate the kit.

Check the applicable maintenance information and the last replacement records. The Mercedes manual also highlights dusty conditions and frequent recirculation use when discussing more frequent attention to interior filtration. This does not establish one fixed cabin-filter interval for every owner.

Before paying, compare the full references, steering-side notes and included components. Keep the invoice and record which filters were actually changed. This is a buying guide, rather than a fuel-system or filter-replacement procedure.
