I use my X300 3,2 every day, and i notised that at some point the interior lights has stopped working, for some time, then last week the Airbag warning light came on.
But the car worked as normal. then i decided i would try to find out what the problem could be so i went through all the fuzes and the only fuze that was burned was the interior light, when putting in a ned fuse it just burned the second it touched the slott with a click.

After that it wouldn't start, even with start cables just to ensure that there was enough, ale lights come on but nothing happens at all. i notised that i can't lock and unlock from the remote either. I can lock an unlock with the key.

So i am kind of out of options, this car has had no problems with any thing, it just run everyday so it is sudden this problem from 0-100 in a flash.

Anyone experienced any like this ore have any suggestions ?

 

I don't think I can be of much assistance, but if I make a couple of comments that may get things moving.
First, if you did not disconnect the battery before swapping the fuse you may have caused a voltage spike which damaged a module.
If there was a poor cable connection from the battery or ground, the spike may have caused the poor connection to oxidize. Check your battery cables and ground connections for cleanliness and tightness. Also look at the two main fuses to which the positive cable connects.
While it probably won't help, do a hard reset by disconnecting the neg cable from the battery and touching it to the pos. terminal for a few seconds.

 

Hi RJ

I will try to make a Hard reset today, and all the cables, se ware its going. They look remarkably fine the cables in this car, but i haven't looked them over one by one.

I notised that the battery in the process in a very short time got very weak and its a big one, i also tried to change the fuse after disconnecting the battery but it just burns the second you connect the battery.

12 volts can cause a voltage spike? This is a first after 28 years in the industry.
Stilling i suggest you get a good electrician to help you instead of reading false theories. The very reason your fuse burns out is there is a short in your circuit and needs to be trace to located which part is not working properly and why the fuse would blow out. Fuse is to protect the equipment from fire.
