My x reg vw golf had the epc light come on i then broke down 2 days later and had to buy a new battery to get it to start again
Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
Hi there:
EPC stands for Electronic Power Control. this means that your vehicle has a fly-bywire system, whish means that there's No accelerator cable and the throtle body is controled by the ECM (Engine Control Module).
If your EPC light comes on there will be a fault code stored in the ECM, any generic scan tool will give a Pxxx code, note it and send us for other details.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

If you are sure you have a key off battery drain, what you need to do is connect an ammeter to the negative side of the battery(disconnect the negative battery cable and connect one side of the ammeter to the battery terminal and one side to the and one side to the battery cable) note the reading and start pulling fuses one at a time making sure to put them back in their proper slot when the reading an the ammeter goes down to normal the short will be on the circuit of the fuse you have pulled if any part of these instructions is too difficult have the problem checked by a dealer

First, to read VW codes you will want to get yourself a $50 VAG tool. It will read all your systems, not just the ECU.
Electronic Power Control can go out for several reasons. Check your brake lights with the car running. Check you radiator fluid level. If the car is running bad, you could have bad spark plugs/ wires or ignition coil.
The traction control is tied into the ABS system and often causes problems here as well. Each wheel has a speed sensor and magnet wheel in the hub. You can check these for damage by removing the tires for access. The sensors come out by hand, and inside the hole they come out of is the place to check the magnets with a flash light. Apply a small amount of wheel bearing grease to the sensor.
The control unit goes out in these systems at an alarming rate. They can be easily removed, and repaired for under $200 at modulemaster.com
Since it is intermit, I suspect most likely a loose sensor, or electrical connector.
If your brakes feel squishy at all, bleed the brake lines of air and contaminants.
Good Luck!
