Punto 1.4 E+ (petrol). Completed 6 years. Has run 58,000 kms. Last service done 3 months back. This problem developed in last 2-3 weeks. One day I went to pick up my son from school. I had parked in hot sun after running 10 kms or so. When I picked up my son and came back to the car it did not start in one crank. In second crank it started reluctantly and started running as if it has no power to idle, but did not stall. Check engine messaged flashed once and disappeared. After that engine picked up speed and ran as if nothing went wrong ever. Next morning it started normally. 2 days afterwards I went to petrol bunk to fill petrol. As usual I switched off the engine when filling petrol. It caused trouble to start after filling petrol. From there I went to a battery shop for a checkup. Battery is 3 years old Amaron long life battery. Battery guy checked sp. gravity of the acid - normal. Voltage is 12.7 V. He asked me to crank the car few times, it started as if nothing had happened. Battery shop guy certified battery is fine. Today I went to market to buy something. I parked in hot sun. Came back after 10-15 minutes and tried to start engine. Again it took 2 cranks to start and flashed check engine message once and then ran as if everything is normal. Symptoms are: Trouble starting the engine when it is hot or when parked under sun. When hot engine starts after couple of cranks and runs as if there is no power in the engine for few seconds and then picks up and runs normally. Check engine flashes once and disappears when this happens. Engine starts normally when the engine is relatively cold or not parked under sun. Battery seems to be fine because the green indicator in the battery is showing green and battery shop also certified it to be fine. Google search indicated it may be vapor lock - petrol vapor in the system causing trouble. The question is - every year it gets hot like this in summer. Why vapor lock now which did not happen in so many years? Somehow it is little hard to believe the story. My real problem is this - I am 180 kms away from service station. It will be a waste of time if the problem does not reproduce itself in the service station. What do you suggest - should I believe the vapor lock story and wait for the summer to get over and the problem to resolve itself? Or is there some way to faithfully reproduce the problem when I visit the service station? Or does this problem happen when certain components age? If that is the case I can ask service station to replace those components.
