I have an Audi A3 TDi and there is a warning sign on the dash like this (0) what does it mean

Time to have a mechanic diagnose it...judging by your description...do you race the vehicle??? is it well Maintained??? Did you buy it new??? have you had the timing belt, and tensioners replaced??? If the timing belt gave way, and there were no funny noises, that means your car has a "non interference" engine, which is a very good thing...find a mechanic that you, or some of your friends trust, and let him/her take a look at it...you might need to leave it for a while...good luck...

Hi your car got a speed warning system in the dash you need to reset it,check on your steering wheel or wiper and inticator levers for buttons for dash menu some models have a reset button also.hope this helps.

3 fuse boxes
Open drivers door,unclip panel end of dash diagram of fuses in box
The other two are under steering wheel,again unclip plastic panel

open drivers door and look on the side of the dash next to steering wheel

I would suggest that you scan the computer for fault codes. There are different sensors that control ignition and fuel and any one of these sensors can cause the car to stall and refuse to start. The crankshaft positioning sensor could be the cause if it has failed completely. The check engine light may be burned out , therefore no warning lights.

this sounds like a faulty 'boot' switch. Many of the older models had issues with picky switches
