Climate control hidden codes

[Bosh 964]

Apparently Audi and Porsche have hidden codes on the climate control, do VWs?

On Audis and 911/Boxsters you could access codes on the climate control display to get engine temp, voltage etc etc. This info was accessed by pressing the 'recirc' button and the 'up' button at the same time. This then gave access to (from memory) up to 49 or more readings.

Sounds really useful

That's correct and is documented across many of the more specific forums like UK-MKIVS.NET

Yeah they do, the info to do it can also be found on audi-sport.net.
My mate knows how and we played around with it on mine. Having a digital display of the rev counter was cool, although apparently you can find a boost gauge but we couldn't.
