I have a `90 750iL, and on the display just below the speedometer and other gauges, "CODE: TACHO" came up, and when pushing the button to read the next message it says, "code: miles/km". Obviously tachometer... right? BUT, what about it? There doesn`t seem to be a problem with the gauges, maybe an electrical problem? Couldn`t find a darn thing about that code in the Bentley book. While leaving for work this morining the " ||| ASC ||| " came up when there was no possibility the ASC actually kicked in. I couldnt have been going more than 10 MPH while leaving a parking lot, which is why I wonder if it`s an electrical problem and there`s nothing really wrong. This car has been giving me trouble, although I still love it. I have a feeling you all will be telling me what everyone else says... SELL IT FAST! (If only someone would buy it.)

No, it`s not a tachometer problem, it`s a secret message from the CIA agent code-named TACHO for you to meet him code (meaning the usual number) of miles/km (depending on your current place of assignment) from your previous rendezvous point. Probably they suspect that the previous agent, JACKO, will be out of circulation soon.
TRANSLATION: I haven`t got the slightest idea what those messages mean either but let me take a WAG at it.
The On Board Computer (OBC) uses various sensors to compute all of that good stuff (and other semi-useless data). I`m thinking one of the car`s sensors might be bad. Study the Bentley`s OBC section and look to see what sensor information comes in and maybe there`ll be a clue there.
Since you seem to have electrical problems you might try the "reset fix", which is to disconnect the battery for a few minutes. Make sure you know the radio code before starting.
