I just installed a Cold Air intake to my 2002 GLX VR6 Jetta and it when smooth and the cars running great but when i started it up the "EPC" , "Malfunction indicator lamp", and the "Anti-slip Regulation" lights all came on this kinda as me worryed because i got the MAF sensor plugged back into its orginal spot and the battery is hooked back up so i dont know what is going on any ideas please?

 

did they just flash on and off or do they all stay on?

 

EPC is "Electronic Power Control". Do your break lights work when you hit the brakes?? The light will come on because of a faulty brake light switch. somewhere there is a problem with the distribution of elect power

 

yes they stay on. i was told that buy undoing the battery and then reconnection it fast can make those lights come on and i did have to do that so i disconnected the batter and reconnected them and the lights when off but about an hour later they came back on.

 

ok so you have an EPC light, AND your brake lights stay on when the car is off? Wow totally opposite of what normally happens, but could be related.

 

well i havent checked my brake lights but i will i think im just going to have autozone run a onboard test tomarrow and see if i can get a idea then hopefully i didnt srew anything up lol [:@]

 

sounds like a coincidence

 

well i just found out my left brake light isnt working but the right one is fine....so idk

 

brake light switch is probably going bad
that is what i have found kicks the light on
and check the conection at the abs pump

 

did you re-check the bulbs??
