I just did an HID conversion and have been having problems with my break, abs, and ESP lights coming on when i turn on the hid lamps. Also it will knock out my speedomitor. After i turn the electrical system off and on twice the codes clear out and everything goes to normal. I was reading that with the vagcom tool you can choose what type of light you have in the car. Do you guys think that this will solve the problem? Also does vagcom log the errors?

 

No, you must have wired something incorrectly, take it back to stock and see if it still does it. If it works fine stock, what kind of HID kit are you using? Ebay perhaps?

 

I have gone back to stock and the error does not come up. I got the units from vvme. It is a plug and play system. My interpertation of this problem is that the inrush current to turn on the ballast is pulling power from the system and causing the error to come up. Once the ballast is charged then the error will not come up. That is why i think that changeing the option in the ECU will let the car see that the current on the line will be greater because of the bulb being used.
