Repair control unit?
A perfectly normal circuit board, with a stable wire protected against brisk theft during the show, the progress of (digital) electronics transformed into reality. However, there is a group of car enthusiasts who could
regret the increase of electronics in our vehicles.
These are the oldtimer fans whose cars are just young enough to work already with such circuit boards and so old that there is at least no
replacement possible by ordinary dealers. Such an old, but precious vehicle can be paralyzed at once and its value perhaps halved.
So far, on these pages, we have always proclaimed the good news that there is hope by so-called universal control units, e.g. in digital
form, which have brought the digital device to work like the analogous old one, e.g. as control of an injection system.
But the friendly Bosch man at the Automechanika has given me a reason, not entirely unselfish, not to do this. Because a complete
reprogramming with hardware replacement requires a new homologation testing. Oldtimer friends drive with such a vehicle illegally.
And if you consider what such a homologation testing costs (not to confuse with a TÜV certification!), then this time Bosch is clearly cheaper. I am
amazed from the diversity of their restorations. When I asked, how old the controllers could be, probably a D-Jetronic from the sixties, he
unconcerned shows me exactly this old (repaired) unit from under the table.
We do not now receive royalties for this page, but we find it justified to report on it. Maybe they try first at a (recognized) electronics engineer.
He will probably be more favorable and can solder at least the soldering points (also with SMD-construction), change reverse diodes and other
easily recognizable components. 10/16
