my car was almost for 3 weeks standing at the airport in freezing temperature and when i came back, it didn't start, so i used another car to deliver power to my battery via starting cables ... when my engine started, i realised that all instuments/gauges and also aircon, heater nad fan is not working ... no speedo, revs, oil press ... nothing ;-/ ... i went through the manual and tried to check all fuses , but nothing found, everything seems to be o.k. ... i can drive the car , the main vital function remains unchanged ... can somebody give me the tip what it can be ??? does somebody have some electrical scheme of the car ?? ... thanks very much for any help !!!

That sounds pretty weird... Isn't it something with the dashboard? I don't think there is one cable that connects everthing that goes to the dashboard, but that is the only thing I can think of because that is the only thing that doesn't work. A friend of mine says it might be a relais problem. Maybe you can give the dealer a call, they can point you in a direction.
However, I'm not a technical person, but I'm sure some people here know some suggestions.
Welcome to the forum and I hope everything will be sorted out.

The second fuse panel on the F355 is in the front of the passanger footwell. You access it by pulling the panel towards you. Per your description, it sounds like the electrical system spiked when you jump started the car. After you check all the fuses and relays, suggest you then reboot the engine management system. You can do this via cutting off the battery using the kill switch, turning the power back on, then starting the car with all electrical systems off (including the airconditioning)and letting it run in neutral on flat ground for 10 minutes. If this does not work, then you probably need to take it to a dealer.
