Hi there. I own a Punto 1.3 MJD and have completed 42000 Kms since Nov 10, 2009. Never changed my battery since then. Never had any starting problems. Rarely used head lamps because I don't drive in night. Late last month, I drove the car till the last drop of diesel and the car did not start (so stupid of mine). I was under the impression that there is some diesel still left and I was waiting for the first of July to fill my tank (easy to keep account). I called my Fiat service adviser Mr Hitesh Patel (Malik Cars, Hyderabad) and he said nothing to worry, just fill diesel and start normally. I did the same and the car started. However, I noticed that the amber colored sign (car and lock) flashed on the dash for a while during driving. I drove few kilometers, filled half tank and parked the car at home normally and went away for a week. After my return, I found the car non responsive to repeated selfs and did not start. I called FIAT helpline and a local mechanic rushed to my apartment with a battery and jump started. I narrated him my background problem and he drained some diesel from the fuel filter suspecting an airlock. The car cranked normally and is running fine for 3 weeks since then. Today again I noticed the same sign on my dash as it did not disppear after starting. I drove for 5 kilometers with that, came home, switched off and again switched on the car. Drove it for a while and this time the sign disappeared soon after cranking and then did not appear again. My fuel level is on the last quarter but did not reach reserve. Now, my worry is, is it due to a weak battery? Is it a self test of low voltage? or is that the Fiat system code failure? The sign is coming with both the keys. I alternate my keys every year or in 6 months. Did any one notice this thing. Please help me.
