Is it possible to retrofit the electric aux heater to an earlier TDi?
If so, where is the control circuitry?
Honestly the electric aux heater is far slower than the Webesto

Yep, tested with VCDS and all spot on.Is your webasto actually working?
However the 5kw also has to heat the block.In my project AMF car the Webasto is a lot quicker to deliver acceptably warm air to the windscreen and cabin than the electric heat in the BHC other - just doing a direct comparison in recent cold weather in terms of defrosting / misting screen on the school run and having some cosy air while driving to work. 5kw compared to 1.5kw doesn't lie.
Is it possible to raise the start temperature?I see the 5 degrees figure mentioned in various places but it's an A2 urban myth The Webasto start is 7.5 degrees C. I believe that once the engine is up to either 70 or 80 degrees and the cabin is up to temperature, it will turn off again if the outside temperature is above 5 degrees. Otherwise it stays on.
True. But I can tell you from direct current experience that the webasto heats the windscreen and cabin more rapidly than the electric heater does in the same conditions - and based on the workshop manual diagram of the way the system is assembled, this is because the output from the Webasto goes through the cabin heat-exchanger first, before going through the block.However the 5kw also has to heat the block.
The electric heater only does the interior.
At best I'll get 120w of heat from a cigarette lighter socket.Certainly for the "non cold climate" countries the Webasto wins hands down. Emission laws apparently was the cause of its demise. The electric heater is AT BEST 1500W ( some were only 900W ) compared to the 5000W Webasto.
Although I would bet that cold climate cars had a different set up as far as operating temperatures and conditions for either the Webasto or electric auxiliary heater and some possibly optional from the dealer such as auxiliary water pump and timers and block heaters.
Back to my earlier post, if you want the instant heat above what the Webasto is capable of then buy a 12v ceramic fan heater and plug that into the 12v socket.
I'm not suggesting removing the webasto, but installing the electric heater alongside my webasto.True.

I understand the point you are trying to make. However, from actual experience in the last few days (and indeed, in the last few winters including last year's morning when we hit -14 degrees here overnight) I find the opposite to be the case by a significant margin in terms of AMF (5000W Webasto) vs BHC (1500W electric heater) when confronted with conditions giving a heavily frosted windscreen (inside and out). That is why the AMF is my official winter car simply because it is so much more pleasant to drive on really cold days because it gets warm in a usable time-frame. If I have time one weekend to get the cars lined up on a frosty day I could probably do a timelapse video.I'm not suggesting removing the webasto, but installing the electric heater alongside my webasto.
The webasto still has a longer warm up time than an electric element.
