My 2002 Volkswagen jetta lights on for traction control and ERP light. Car has no power.

EPC light should have nothing to do with the shift interlock,(EPC is traction control) should be a small cap or plug on the console, near the shifter that has the interlock disengage button,usually done with a key,check shift interlock in the owners manual.

Yes sounds like the alternator. Check terminals and grounds. Check alternator output with a multimeter.

the rotors might be bad

this was probably a traction control that came on

try unplugging the battery and replugging it and then starting the car. hope that helps

here is a simple sulution while car is running, pull off the negative off your battery for 15 seconds and hook it back up. if that don't work you have others probs.

its most likely the traction control warning that the wheels had spun and power was briefly reduced to stop wheelspin. there should be a switch on the dash centre panel with TC or ASR if you press this switch it will put the triangle light on constantly until pressed again. this disables the system so be careful as wheelspin will be inevitable !! lol

traction control

fuel filter can be getting gelled up, ecm has to be checked or could have a loose connector in engine compartment or broken wires. many times fuel pump relay or main relay will cause weird things in these cars

sounds like you need to reset readiness ,which resets throttle and several other things. unfortunatly it needs to be done with vagcom or vcds software, so back to dealer or a reputable VW repair shop
