We had a family friend round to day and she was not in her normal BMW car. Instead she had a little French Car so I asked her why. Answer is she lives in the country (like me) and she went to strart the car up and a warning light showed. Last time this happend (its a 3 year old car) it was because Rats had got in the engine compartment and eaten through the wiring. Sure enough same thing has occurred there were cut (rat eating) wires all over the place. BMW Garage came and took the car away and service manager told her this is not uncommon. Last time it cost her £350-00 but this time she is expecting it to cost more.
