Have to agree - can't see anyone typing in Servertronic, but it could be okay for a hosting firm for example as a brand name but that all limits its resale value unless you get the ideal buyer.
Found this in a link to a user group - concerns a Vauxhall Senator car:-
"Severtronic controller, I dont think there's a diagnostic part for this BUT from memory unplug the controller (front right wing above drivers foot on the 24v) and plug the wires together, this will in put the pump valve to FULL so the PAS is on full all the time. Not a good idea as I went through front tyres in about 8 weeks doing this. But will show if its the servertronic controller or not (or a pump / valve problem)."
