Hello,
I do have a DS23 ie for quite a while and had the same problem 15 years ago.As far as I can remember the most important thing was to push the accelerator all the way down before turning the key. I also istalled a thermo and time controlled switch for the electric fan, that made it run for five minutes or so after the ignition is switched off. The temperatur is controlled by the air under the hood, not the water, since it is extremely hot, especially when the A/C is used.
One other item that contributed was a tiny craze under the compensating reservoir for the coolant, that only opened when it was nearly boiling. That sprayed water on the spark plugs and other parts of the ignition system.
Even here in "Bosch-country" I can't find a mechanic who knows enough to fix the D-Jettronic,
Have fun with this fine car!
Greetings

Hi,
that could be due to the fact that there is no D-Jet t ronic in Bosch-country.
