A replacement BCU needs serious programming by someone who knows what he's doingQuote:

Point taken. I won't rush into it unless really needed.
Would appreciate some feedback on whether, in my case, the risk of lockout is high (and I need to something soon) or low/lowish (in which case I can proceed as is and just monitor things). In particular, would like feedback on whether door lock/unlock failures are more commonly switch or actuator failures (see my train of thought below).
Update: Sierrafery's prognosis seems to be right - ie the BCU is going to sleep too quickly. The other suggestion of the battery being low doesn't seem to be the culprit because I connected a trickle charger overnight and the handset failed this morning.
From what I can work out, the BCU normally gets and responds to lock/unlock signals/currents from two sources:
In my case (once parked overnight), it's just one source - driver's door. Thus I'm totally reliant on the door switch working. By the same token, as long as the driver's door switch is working such that, on turning the key, a current is sent to the BCU and the BCU wakes up, I should be okay and not be locked out. That is, I should be okay even if the driver's door actuator fails (provided the switch works).
- a receiver in the roof that responds to the remote, and
- a switch in the driver's door.
Assuming the above is broadly correct, I'm interested in feedback on whether door locking/unlocking problems are commonly driver's door switch problems or actuator problems. (There seems to be a number of posts on actuator failures but haven't read them in detail to see how many involve switch failures.) My thinking is that if there are a lot of switch-related problems then I need to be careful, but if most are actuator problems (and switches are pretty reliable), then I can be a bit more relaxed.
Any feedback much appreciated.
ps - how do you put a quote from a previous post in a text box? Looks good but haven't figured out how to do it.
The switch is part of the actuator;)Quote:

Sorry if I confused things. Have not seen an actuator to know what all the bits are and how they work. What I am trying to work out is whether actuator problems are mainly due to or result in failure of the switch to be able to open/close the circuit to the BCU. If that is the case, actuator failure will leave me locked out. If, however, actuator failure is commonly due to other things - eg the locking mechanism itself braking in a way that doesn't stop the switch opening and closing the circuit to the BCU, then the risk of lockout reduces. This is because opening/closing (not sure which way) the circuit to the BCU should wake up the BCU (even if the driver's door itself won't unlock due to other problems) and bring the handset back into play. That's my thinking anyway but could be off the mark. Comments most welcome.
