147 Battery drainage
The story so far:
One morning a few months ago we couldn't get into the car the normal way, i.e. with the remote fob. The engine wouldn't start because of a flat battery. The RAC man came, tested all the fuses and relays, and thought it was the radio that had caused the drainage. He disabled the radio (and consequently quite a few other useful functions!) and charged the battery. We took the car to our Alfa specialists in Oxford. They checked the radio - which had nothing wrong with it.
We took the car back - and suffered the same battery drainage after a week or two. Off to the specialists again. Now they reckoned it must be a faulty body computer, so they ordered one from Italy. It took over a month to come and once installed worked for another couple of weeks before it was the same old story once again! What happens is that the radio turns itself on, and if you don't notice it, and don't use the car for a couple of days, the battery will drain.
So we charged the battery and took the car back to our specialist friends. The kept it for a couple of weeks, scratched their heads, did diverse test and checks, and the radio didn't turn itself on once! So we picked the car up and - lo and behold! - after a couple of days at home the radio went bonkers again, and it now turns itself on 3 or 4 times a day.
It's a 2004 147 1.9 JTD with just under 20 000 miles on the clock - and we're getting a bit desperate! Has anyone out there experienced the same problem? Grateful for any hints and tips!
