fault in which control unit?

Check the timing belt. It should have been changed at 60,000 miles. Sounds like you have lost some teeth on the synchronous belt resulting in lost timing. Damage to valves can occur. look under plastic cover on the end of the head for the belt

This happend to me it was the 30amp fuse under the bonnet the legs where green and the socket was the same after a good clean it was fine there is a part of the ecu behind the glove box and some relays there to but if the main fuse arc,s it makes the relays flutter as it loses power

remove the sensors off the rear C pillar will that stop the alarm from going off. (The bit that looks like a tiny speaker.)

fuse labelled 'F1R' which is 20A and dedicated to the rear fog lamps. Interestingly it looks like this same fuse also is responsible for all the rear brake lights. If they don't work either, then this is the culprit. If they do, then work back from the rear cluster assembly to check for faults. Firstly, the wires to the fog lamp should be white (live) and black (earth). The only other difference I can spot is that they do NOT share the same earthing point. They are labelled on the diagram as E8 (brakes) and E7 (fog lamp). The earth point is maybe a grey wire on the right hand tailgate /might be the other side on left hand drives. It may be loose or corroded. Switch on fog lamp and use a multimeter to check the earthing and if voltage is present.

have you checked battery is fully charge, test with multimeter good battery will read 12.6 volts or above.
