Hi,
I have this exact problem.
Battery went flat during the cold snap. Called recovery and got the car moving. Ran and recharged the battery, but since then the boot will not open to key fob, interior button or exterior button. All other electronics appear to be functioning normally. I've read the forum entries and I've checked the valet button near the glove box without success. I've also attempted the reset approach, but this doesn't appear to have worked.
Any advice?
Thanks in advance.
