J255 Climatic Control Unit
Does anyone have an internal wiring diagram of J255?
Or does anyone have a faulty one that I can strip down?

J255 Climate Control
This is the unit at the front where you can set the required temperature etc. I want to connect to the contacts of the "ON/OFF" switch. A non working one will suit me so that I can get inside it and see where two wires can be connected.

What project are you planning Ray?
There's a unit on ebay for £22.50. Other than that give A8Parts a call

Morning Matt.
I have been using the Webasto to warm up the cabin on cold mornings. I have not added the water pump and pipes to install the full system. On cold days I head out in slippers etc., open the car, press and hold the "ON/OFF" switch on J255 until the temperatures display. This fires up the blowers and Webasto. I can then lock the car and go back indoors. Twenty minutes later I can go out to a defrosted, warm and toasty A8. Now the project. Dah! Dah!. I have a remote control sender receiver pair. The Rx has a relay with normally open contacts that I would to connect electrically across the contacts of the J255 On/Off switch. If that could be done then I could remotely set the Webaso etc. going from the bedroom, have a wash and the car would be ready for me. Total luxury at up to now no cost!!!! If no one offers a J255 I was planning on trying A8 Parts. I don't want to break into my working unit until I have a decent idea of the problems that may arise. Even a circuit diagram of the internals would help.

I see what you are planning to do Ray.
Would adding the T90 Telestart to the webasto do the same job, or do you need the pump and pipes for the full system? T90 Telestart (4F0909509 + 4F0909507B) is connected to the Aux. control module and in turn J255 via CAN. OEM albeit more expensive. http://allegro.pl/sterownik-pilot-we...162265331.html £65 but with a VW fob. <--- Now Sold, someone on here?

The days of being able to go out and buy whatever I wanted have gone.
The big effect of Gwen's illness is the loss of another income. I have to watch the pennies!!!
