after several battery replacements, the battery still goes dead in 4-5 days. after several non-diagnosis, a repair shop tells me they think it is the "engine control system" at the main computer.

Possible or?

draining in just a couple of days , there is definitely a draw somewhere. A faulty engine computer can cause it to drain. Have they ruled out all others such as stuck open relays, switches etc.. that can keep drawling currents without the key in?
