Has anyone had a problem with battery discharging on the new Fiat euro5 engine? The other day we were due to take van in to have a replacement sat nav fitted. Enginge wouldn't start:Sad: Put on charge for an hour started Dealer said it is a problem with this engine if not used for 10 days or so and it tells you in the fiat handbook. Wanted to sell us a solar panel for £750 We have had numerous fiat motorhomes and never had this problem. Spoke to Fiat today and they suggest using the battery disconnection switch and then use the key for opening doors when it is not in use. What then happens about the alarm I say...you will have to leave it switched off they say...but what about the insurance I say if alarm isn't on no insurance. Sorry that is all we can suggest:Sad: Any suggestions gratefully received .....we have thought of going down the solar panel route as the van has everything in place just needs a panel and wire to control box.
