I have been t/s a 211, and noticed that the readout on the lcd screen, will usually tell what opmode it is in, what floor etc. every once in a while, the screen will display the floor number and iii, then will go back to the floor number and IDL, or NOR which is usual. so instead of 2 IDL, it will say 2iii, then will scroll and say 2 IDL again. is this iii thing something to worry about or is it normal, i can't find any thing in the manuals about iii in the opmode codes. just wondering if this could be a sign of trouble. thanks . also one other thing is there any other situations which could cause a STLU besides the valve not working properly, or one of the hatch switches malfunctioning. I have an intermittent STLU that has happened 7 times in the last few weeks. I was there for the first time yesterday, and ran the car all day without a glitch, it came in again sometime in the night, I have tried to simulate this in various ways, but can only simulate it by opening up the valve coil circuits. I ran it all day today, thinking i would see at least some problem with the valve but it ran again without a glitch, it relevels fine, one note, it does park at the 2nd floor after about a minute , i tried relevel at the top floor, and no problems there either. My guess is something is going on with the valve, but you would think after 2 days of running it you would see something, hate to call for a new valve and have it go down again, pissing off the customer.
