Rover Eprom -
On the Land Rover the TD5's are known for oil getting into the injection harness and making its way to the ECU. On the LR this is identifable by looking at the red plug that goes into the ECU, if this has oil on it the harness needs replacing, and then every few days check / clean the red plug until the oil stops.
Probably nothing like this on the MG but maybe worth a check?

Hmmm. Doesn't help.
The 200 series (200,25,ZR) Have both systems but it's most likely to be MEMS. No way of telling without actually looking at the ECU. Picture possible?
That said and looking back at your original post you mention alarm/indicator problems. This is interesting because the 200 series isn't K-Bus - just straight switches/relays/wires therefore any electrical problems are rarely ECU based. However, it sounds like your alarm/immobiliser might be throwing a wobbly.
You can disable the alarm using a code sequence and entering it by turning the drivers door lock to unlock/lock etc. If you don't have the code I have the Rover master code - PM me.
But - I must know the ECU type before we do this.
Finally. A re-flash will do nothing for you.

You still need to know whether it's MEMS or T4. MEMS you can just swap. T4 you can't and it's very expensive to get sorted. The T4 is coded to the instrument cluster, keys, ignition key switch etc etc. It's not a re-flash although it's often described as such. I hate to say it but you could be getting into more money than the car's worth.
Have you done all the simple things like drying everything out, check the door/bonnet/tailgate switches, the ultrasonic sensor etc?
