Your EPC stands for "Electronic Power Control" and without it (bypassing it, as you stated), you will not be going anywhere in your car. The car MUST have the EPC on/enabled to run, as I have been told. The VW Passat does not have a throttle cable... it is controlled electronically. The EPC light means something is wrong in the drive-by-wire path, the "gas pedal" potentiometers or the electric motor-controlled throttle body, etc. You will need to take it to a mechanic/repair shop that is knowledgable in foreign automobiles (especially VW's) and has the appropriate tools and equipment to read any "codes" being kicked out by the computer.

I have a 2001 New Passat with the EPC light coming on randomly and it will idle high but next time I start the car it goes away. I think you will have to take it in to the dealer.

If you turn the key to acc, nothing happens, if you turn it to on, nothing happens, but if you turn it all the way to start, it does star but when the key springs back like normal, it turns the truck off....


did you replace the switch or did you replace the ingnition cylinder (cylinder is the part the key goes in)the switch is what controls the start acc and keeps the car or truck running

Question:
Did you replace the ignition switch or the KEY AND CYLINDER?

These are the only 2 things that can make your engine turn off when you release the ignition switch after starting the engine.

I hope this helps you.

2004 jetta does nothing when key turned


these motors suffer from dodgy starter contacts on the ignition switch,turn key and all lights on,push car and it starts ok but no starter motor.??these switches are dear as its a complete unit with steering lock,if this is the fault then fit an old fashioned push button switch on dash ---sorted.If you say epc light on then this is immobiliser ,try spare key if that dont work then its a dealer job to reset immobiliser unless someone knows how to by-pass it.Havent done one yet so i dont know how too,but i itching to get my diesel oil covered grimed in black hands on one to try and pit my wit against a four eyed nerd that invented the immobiliser system.
