Default 04 CDTI ZT VIN/drowned ECU/key question

Hi all, I only have the one key, RCL has never worked since I've had the car, osf door latch is faulty.

I'm concerned at only having one way into the car so need the RCL working. The closest people I've found to do it are 25/30 miles away and closest who can cut a blade another 10 or so on from them.

Long story short the guy asked if I knew the history of the car and whether it had had a drowned ECU, ie if it's had the required components from another car we will have problems with codes stored by BMW, so before I made the trip I thought I would see if the ECU VIN matches the car.

Option 1 on the self test function gives me a matching 5 digits to the last of my VIN plate. Does this mean I'm good to go and the cluster reads the VIN straight from the ECU or is the VIN written to the cluster so wouldn't change if a rescue kit had been fitted?
