Stuart A Posted October 16, 2009 Report Posted October 16, 2009 I have a 130 TDi Alhambra and was wondering if anyone had converted the boost heater to work as an auxiliary heater which I understand was an option in some countries. Has anyone a copy of the wireing for the aux heater, I am an electronics engineer so I am sure I can make up the required electronics, I have searched and read most of the posts on the boost heater Stuart Quote

Stuart A Posted October 17, 2009 Author Report Posted October 17, 2009 Thanks for that, I still need to know how to power up the heater the water pump and how it all connects to the second battery. Stuart Quote
Mirez Posted October 17, 2009 Report Posted October 17, 2009 Thanks for that, I still need to know how to power up the heater the water pump and how it all connects to the second battery. Stuart Hi Stuart, its something I'd like to do myself. The control panel fits in the overhead console on the Mk2 and replaces the alarm sensors (which begs the question where they go but anyway) - its not the same as the panel shown in the link as thats a Mk1. The wiring seems reasonably simple, its a seperate loom entirely for the timed heater so it would need to be hardwired into a car that wasn't fitted with it as standard. The aux battery sits below the passenger seat and is charged via the alternator the same as the main battery. It powers the diesel pump, control panel, diesel heater and the electric water pump "run-on pump". It uses a number of relays of which I've not found all their uses but the main one seems to be to power the water pump and give back control of it to the ECU when the main engine is started. If I can get hold of the overhead controller then I'd give it a go as I believe the benefits are quite large, but the controller is a little over Quote

Stuart A Posted October 22, 2009 Author Report Posted October 22, 2009 From wat I have read the same heater is used with the extra battery powering the boost heater, heater fans and the aux water pump. Stuart Quote
Mirez Posted October 22, 2009 Report Posted October 22, 2009 From wat I have read the same heater is used with the extra battery powering the boost heater, heater fans and the aux water pump. Stuart Which is correct, is definately the same heater and not an air heater. Quote
marinabrid Posted October 22, 2009 Report Posted October 22, 2009 someone on here a fair while ago posted a link to a german website where it was shown how to turn the standard aux heater into a timed one , i looked at it and couldnt read german mein heir Quote

The programmable heater is a water heater not an air blower. Quote
