Angel Eyes Wiring - Losing Power After 30 Secs
I purchased angel eyes from retrofitlab in the Netherlands. So 4 eyes in total with a positive and negative on each. I've tapped the positive and negative of each set together and tapped them both into the parking light power. They need to be tapped to this as I'm removing the parking light and need to comply with national car tests. When I switch on the car and turn on the parking the angel eyes light up as expected but after a short period, maybe 30 seconds, all 4 turn off. I've checked the power with a multimeter and the socket is getting 12v and goes immediately to 0v when it loses power. I unplugged the angel eyes and checked again and the plug gets 12v indefinitely then just as if a parking bulb was plugged in. Are the angel eyes drawing too much power and the systems cuts power? Any solutions?

I've already done that as I've retrofitted xenons also, but I'll double check that I've coded out the parking bulb check, one set of angel eyes came with small led driver boxes, and the others didn't, I'm not using these boxes, think I've blown one of them, but when I had them connected the same issue was occurring.

Probably still need more coding. If the voltage goes from 12 to 0 that is a strong indication that the vehicle is cutting power through the ECU as it's sensing a fault.

Ye when you say it like that it sounds like a coding issue, I'll double check all the bulb checks etc. tomorrow and see if solves anything, thanks for the reply

What happens when you power the angel eye bulbs directly with an external 12v source? IE directly from the battery?
If they shut off as well, issue is the bulbs. Also what happens if you just switch ignition and do not turn on the engine? Same issue? If not, it's a PWM issue. |

And even if I have ignition off(just switch dial one notch), on or engine on i get the same problem and only way to 'reset' everything is to turn off and on the ignition |

I've just checked and all bulb checks botg warm and cold are deactivated, I followed a guide on here for the coding, bulb checks for brake lights etc. Are still activated but anything to do with parking lights are deactivated, but bulbs still go off after a short time.

Sorry for all the replies, but that fsw psw file is actually for the whole car, ie when you first go into ncs expert and select your chassis and it shows vin etc.
I notice in that file there is a hot and cold bulb check for the side lights that is still set to active but when I select frm module and go to change that line it's not there, all that's there is hot and cold bulb check for parking lights left and right but not the generic one found in the original file. Any ideas how to change this line? |

Assuming you have a FRM2....PWM_SL_V typically sets AE voltage. Yours is set to Wert_1 which is 13v.
If your replacement AEs are driven with a cheap Vreg/Resistor setup, 13v maybe too high and kicking the AEs into thermal protection. Try using Wert_05 which is 11.7v |

i'm sure it's the FRM messing with your angel eyes/side light voltage output
i guess you need to find the nanny and code it out. your previous fsw psw file is a generic one and won't help. read out your frm module then post that fsw psw here.

Also would it help to post this file on the coding section? |

You should VO code the car for xenons and see what happens. Add option $522 to the VO and write the new VO to CAS and FRM. Then default the car, at the very least, the FRM module. |

When I check my frm module after writing the VO I don't get the expected line of PWM_FL_BEI_BIXENON wert_02 wert_03 But instead I get PWM_FL_BEI_BIXENON wert_01 The same as the member in the photos I've attached. I don't know how to change the trace file though as to get to the getfswpsw function I need to select an individual module This may not solve anything but it's the expected frm stock value after writing the VO |

I've tried all these and I get an error when writing the lines when I try to actually write to the car as if wert_04 isn't valid parameter
PWM_ANSTEUERUNG_SL_V_AL wert_04 PWM_ANSTEUERUNG_SL_V_FL wert_04 And the line PWM_ANSTEUERUNG_SL_V wert_03 Just changed that the angel eyes don't light up at all with switching the dial one knotch and only turn on with the xenon dips but they still turn off after a short period And the line LOAD_DUMP_SCHUTZ_SL_V nicht_aktiv Didn't seem to make any difference to anything I really appreciate everyone's help on this as my knowledge of coding is limited |
