Here's the official 'additional heater' manual for the A2 - scour it for clues and info.
This explains there is something within the E87 climate unit sends the 'fire up' signal to the ECU and then the Webasto when all the criteria are met.
Mine still won't fire up even after replacing the malfunctioning temp sensing component on the webasto circuit board. I think the thing in the E87 could be the culprit behind these issues but no idea on what a possible fix might be.
Hopefully the manual might give somebody the clue we are looking for.
