VW Golf / Passat / Skoda Octavia Heater Core 1H1819031B / 191819031E

Product overview

When the cabin heater blows lukewarm air, the windscreen fogs with a sweet smell, or coolant appears on the passenger footwell carpet, the heater core is often to blame. This replacement heater core (heater matrix) is listed for Volkswagen and Skoda vehicles under OE reference 1H1 819 031 B and a range of related numbers, helping restore cabin heating and demisting performance.

Vehicle compatibility

The listed fitment data is very broad, with 200 entries. Examples include:

• VW Golf II, Golf III and Golf IV, Jetta and Corrado
• VW Passat B3 / B4 and Passat Variant
• VW Polo Classic, Polo Variant, Lupo and Caddy II
• VW New Beetle and Scirocco
• Skoda Octavia I, SEAT Ibiza II, Toledo I and Leon, Audi TT and A3 / S3

These vehicles span several platform generations, and heater cores differ in size and pipe layout between them. The 191 and 1H1 part numbers relate to earlier Golf and Passat platforms, so later models in the table may require a different part. Treat the list as a guide and match the OE number on your existing heater core or confirm by VIN.

Technical specifications

Installation requirements

Access to the heater core often involves partial dashboard or heater box removal. The cooling system must be drained, refilled with the correct coolant and bled of air afterwards. Professional installation is recommended, particularly where air-conditioning or airbag components need to be disturbed.
