NG engine vs. warm-up regulator ???

["Martin Friedrich" <Martin.Friedrich@Informatik.Uni-Oldenburg.DE>]

Hi, all!

The talk about sporadic sputter on acceleration being caused by a bad
warm-up regulator a few weeks ago, made me wonder about the special
case of Audi's NG I5-engine. These engines have ( acording to my sources
and views onto the engine block ) no warm-up regulator. This rises
two questions:
1) How does the NG engine ( or it's K-III-Jetronic ) control warming up
   ( is this hardwired into ignition/injection control ) ?
2) How can I check correct operation ?

Bye,
