Just putting this out there. We all drive an MQB VAG vehicle. For some reason Audi and VW 2.0 TDI's get a PTC ceramic heater in their heating unit. Skoda in the uk seems to have scrimped on this piece of kit. Could have done with it this morning. I have done some research and the parts are available. some of the wiring is already installed but some of it is not. Basically from what i can see it is a PTC element, 2 relays, 3 fuses and some wiring and connections made to engine ecu and running cables from the underbonnet fuesbox to the heater element.

Has anyone ever attempted to do this? do you own an Audi or golf with this kit in and does it make a difference? please let me know, If it is possible to do i will do it and add a guide for it. I need some part numbers for connectors specifically in the under bonnet fusebox for the relays (small pins) and some connectors for the green 40 amp fuses. Also i need some info on which pin on the engine ecu to connect to and the connector involved. 

 

TIA

Just replied to your PM, although now I know you're looking to fit it to a MK3 Octavia you should ignore the links/parts I mentioned.

 

Anyway, our Russian friends have already achieved this

 

There might be part differences for a LHD vs RHD car but the following links should give a general idea:

Just check the pins match for your ECU, Wiring diagrams can be found from Skoda for a small fee: https://erwin.skoda-auto.cz/erwin/showHome.do
