Audi A4 B9 / A5 / Q5 / A6 C8 Heater Core Aluminium Copper 4M0898037C

Product overview

This new heater core assembly is referenced to OE number 4M0898037C and is constructed from aluminium and copper, according to the listing. The heater core transfers heat from engine coolant into the cabin, so a blocked or leaking unit can cause poor heating, foggy windows, a sweet coolant smell inside the car or damp carpets.

Coolant loss without an obvious external leak and a film on the inside of the windscreen are also common indicators.

Vehicle compatibility

The listed 200-row fitment table is mainly made up of recent Audi models, including:

• Audi A4 B9, A4 B9 Avant and A4 Allroad B9 – from 2015
• Audi A5, A5 Sportback and A5 Convertible (second generation) – from 2016
• Audi Q5 and SQ5 – from 2016
• Audi A6 C8, A6 Allroad C8 and A8 D5 – from 2018
• Bentley Bentayga – from 2017

However, the listing attributes also list earlier B8-generation A4, A5 and Q5 models, and the table includes an electric SQ8 e-tron entry. Because of these inconsistencies, fitment is treated as partial.

Key features

• Aluminium and copper construction, per the listing

Technical specifications

Installation requirements

Heater core replacement typically involves significant dashboard or HVAC box disassembly and may affect airbag components. It should be completed by a qualified technician. Drain and refill coolant with the correct specification, bleed the system and check carefully for leaks before reassembling the interior.

Flushing the cooling system can help prevent debris from blocking the new core, and protecting the interior during removal is advisable.
