The chaps at the track day hire company (next to where I work) have a 420R road car that they need to get back on the road after a fire under the scuttle. Fuel pump tripped on last lap of day on track. This morning, on lifting the scuttle, it's all burnt out around the three immobilizer units. If you turn it out now, it starts again but it catches fire! Can it be removed and another one easily put in. It's a Sterling XL immobiliser.
