Hi there, on my xc60, drain tube had become disconnected when it goes past the dash. As a result, I had driver footwell full of water puddle.
I have had that repaired since.
But I cannot open my boot now - it is permanently locked.
This model doesn't have a boot opening function for on remote or on the front dash.
Now my feeling is it's the cem that is buggered due to water damage.
So, should I get that out and get it looked at ? Or try looking at the bootlock from inside?
Problem is I don't know how to get to bootlock from inside.
Could someone give me pointers.
By the way, all other functions and electronics are working fine.
Any help will be greatly appreciated.
Thanks in advance.
