The soft close on my boot lid works for a little while whenever the battery has been disconnected, but after a couple of days just quits. Anyone know what can cause this?
All the doors soft close work fine...

It sounds like the pump is running for too long after operating the boot closing mechanism. This will cause the ECU to shut off that part of the pump, to prevent damage (overheating) to the pump. This also explains why it works for a while after disconnecting the battery, as this will reset things. You should have a code(s) logged if this is happening - have you read the stored error codes?
