I have a 2003 A4, the EPC light has been going on and off for a the last month or so. Usually when I restart the car maybe 1/2 to hour or so after having used it. The engine will crank for 30 secs and will not start. After a few trys it starts again. Should I address the problem ASAP before it gets worse, or can this wait till I see what happens next?

Most likely if you have the model that is drive by wire aka electronic throttle body the 9 times out of 10 your gas peddle is on it last legs replacing it will most likely solve your issue with epc light comming on
When was the last time you changed your Air filter( A dirty filter can put MAF sensor out of range). How about the fuel filter (Fuel starvation). These filters should be changed every 30,000 miles . It is normal for all of the dash lights to come on if the engine stops running. Is the Jetta a Diesel or Gas. Perform The OBDII scan again to see if current faults are present. Do the cheapest fixes first. Also check oil often. The low oil sensor will trigger engine shut down if more than 1 quart low
I am having the same problem on my Audi A4 2004 FSI, lose power whilst driving at speed with the EPC light coming on. Looks like a design fault of some kind with Audi petrol engins, have read a few forums about this but no clear straight answer. Check the link below:
I am not entirely familliar with this particular model, although in some similar models that I have worked on The epc (on deisel models) usualy indicates a problem with the particle filter.
This means that if your car has a particle filter and it has not reached a temperature that it can clean itself for a few months, it may become clogged and cause a restriction for the engine.
If you take your car to an audi dealer the mechanic will be able to do a quick test to confirm and he may then be able to overide the cleaning process and clean the filter. I would advise that this is done asap as dammage may be caused from very high exhaust temperatures.
your crankshaft positon sensor is defective. Replace it and the epc will never come back and no more dying out. this happened to me several times and it would just come and go. i replaced it and now the car starts right away and the epc light hasnt returned since
go to autozone the brake light switch is maybe $10 and easy to install yourself looks like a plug and is usually located under the brake pedal look brake light switch up on google and should find install instructions thats what i did and saved $100+
Get it to the dealer or a specialist auto electrician and find out why the engine management light is on. That and the other warning light is telling you there is a significant problem with the engine!! Not dealing with it WILL cost you a LOT of money!!
