Ready to race!
Solved: Front Driver's Turn Signal Always ON
Background:
Bought a set of ED's Headlights (HID Projectors) due to great reviews. Picked up a H7 35W Morimoto d2h kit with canbus for the lighting. There was no splicing as everything is plug and play. No additional mods have been made to the car.
Problem:
The Front Driver's Side Turn Signal is stuck on. It will not turn off unless Driver's side harness is disconnected from the connector on the headlamp assembly.
The problem seems to be coming from the car's wiring harness to the connector.
Symptoms:
Tested the wiring harness and there is constant power from battery/Cecm for the driver's side. The passenger side headlight harness does not have constant power which makes sense as the front passenger turn signal is fine. All turn signals are operating correctly with the exception of the front driver's turn signal.
DRL's have not been turned off as I have not been able to find someone with a VagCom. DRL warning on the MFD and check front light bulb.
Plea for Help:
Trying to resolve this without having to take the car into the dealership since they will most likely deny the warranty claim due to the aftermarket headlights. Alternative is to put everything back to stock which is a PITA.
Solution
Replace the CECM. If warranty will not cover it then you will have to come out of pocket to replace the unit. PN is 5k0937087 and has a MSRP of $260 but can be found for $200 from VW OEM Online Part Dealers.
A few people contacted me with the same problem and most at some point had put in aftermarket lights in their cars. Ed's Lights, Spyders, HID Fogs...it was all over the place so a general warning is in place about tinkering with the lights.
