lpgde fan on problem

friends car 207 sportium 1.6 120 hp. Especially when I use the car with an LPG-mounted LPG in the LPG , the radiator fan starts to work after I have the vehicle STOP (the temperature indicator is at normal level). There is no error code that I connected the tool to the computer. I also went to the LPG room room bole said that it is not possible.

At 207, the fan works hard, it is normal. Actually, it doesn't work when you stop the car, but it works as it is, but it is like working new when you get out of it because it is never heard in the car. The fan works in two ways, fast and slow mode, this is the slow one you call and it usually works in city driving and continues to work until the water drops to a certain temperature even if the engine is turned off. fast mode works quite effectively and for a short time, it can be heard if the window is open. Maybe this is also the case for you.

Thank you for your answer, but unfortunately this is not the case I have tried many times. azonce I started my car parked for 2 hours at 5 minutes lpg, stopped the car in the relay, the fan started again. Then I bought the car for gasoline, took the vehicle for 3 km, stopped it and did not open the fan. this problem will make me crazy: (((

If the lpg software is reinstalled, the problem is solved then I think.
