What is the beeping noise in a Fiat punto?

Answer 1

I was looking for the same answer, but I think I have worked it out on my journey home. I have a Mk2 2002 Punto Sporting 1.2 16V.

After travelling a while I got a beep come over the stereo every 30 seconds.

This carried on and on. While travelling I identified that if the TA (Traffic Announcements) was enabled the beeping starts when the current Radio station starts to get a poor signal. I was listening to a national station and had traveled a long way and I needed to switch to another frequency to get a stronger version of the same station. Once I did that the beeping stopped. It only seems to whing if the TA is on. I notice the radio is not RDS (well I cant find on RDS logo on it anywhere) and so it does not automatically follow a station and switch to the strongest signal as you move through the country.

Well that is what I worked out in 2 hours of travelling within 12 hours of having the car!

I also diagnosed that an engine management light which came on a bit later, but that was an early warning of oil level. It had reached 1/2 way between min and max and a top up, turned the EML light off.... Result!
