Is it possible to disable checking of LED lights ? Or suppress MFD bulb out warnings?

G'day. I've fitted LED DRLs and LED Reverse Lamps to my MY12 VW Passat CC.

The MFD displays 4 x warnings constantly (or you clear them with 'OK') til the next drive. VCDS scan shows the 09 - Central Electronics error as "bulb out or short to ground" for each of these LEDs.

Whilst I know I can fit heatsinked resistors across each of them, it sort of defeats the purpose of LED efficiency. Plus, the resistors get real hot, and are a waste of electric power. Additionally, I believe the circuits may be current limited, so the resistors could then reduce the light output of the LEDs.?? :confused:

Instead, I've been researching & experimenting with VCDS Long Coding but have not been able to disable checking of the Daytime Running Lights check, nor the Backup bulb check.

Is there a way to code to prevent CANBUS checking these specific bulbs; or prevent displaying of light out errors on the MFD?
Cheers,
SM

Please post an Auto-Scan so people can see exactly what BCM is installed in this car and how it's configured.

I've performed a full Autoscan to hopefully help get this issue sorted for me and I'm sure, countless others who are retrofitting LEDs in their late model cars

THANKS IN ADVANCE

I was hoping that there was a solution to this. It's really distracting getting pop up errors frequently on dashboard display while you drive.

To further the collective knowledge - I ran a test of brightness with and without resistors across the LEDs and they are slightly dimmer with the resistors in place. They also get very hot very quick and are a drain of electric power (and fuel).

My research since posting this has found that the potential solution is in Byte 18 of Central Electronics. However, deciphering that is tricky. Truth is, I don't know if there is a code that suits the configuration of LED driving lights (at the minimum) with Bi-Xenon headlights and foglights.

However, what would be great is the ability to stop the error from popping up while you drive all the time.

revhead: hi. I don't know the answer to your substantive question, but I'll have-a-stab at commenting on your observation above

As to the first part: LEDs are really efficient devices and they only need a small amount of electrical current to produce a high amount of light. This is why you are getting the error message - because the car's monitoring ciruit thinks that there is an incandescent lamp and the small current is being seen as an open filament fault). Adding the resistor means that you place a relatively high electrical load in parallel with the LED. As a result, the additional load from the resistor causes Volt-Drop (sometimes abbreviated to VD - not to be confused with the other same acronym for the sexually transmitted disease!) at the point in the wiring loom where the LED is connected. The reduced voltage from VD means that the available current to energise the LED drops slightly. Since LEDs are constant current devices (not Voltage devices) and because the light output of an LED is highly sensitive to current, the amount of lumens from the LED drops a little. Hence your observation!

As to the second part: The observed heating comes from the relatively high energy that is dissipated by the resistor (it's sometimes called I^2R losses). The job of the resistor is to simulate the minimum current that would normally flow from the filament of an incandescent lamp. However, unlike a normal lamp where some of the supplied energy is transformed to light and some to heat, in the resistor, all the energy becomes heat - hence your observation.

I apologise if you already know this stuff!
Don

After months of trial & error (and no solution offered here) I came up with a solution! However, it's not 100% so hence another question. PS - this is after trialling higher resistances (around 60 Ohm) to reduce the power loss but still have current which reduced the frequency of the errors.

I disabled DRL on the dash MFD, then disabled most DRL options using VCDS. I disconnected the LED from the DRL connection. I then soldered long cables to a bus-bar (aluminium plate) mounted on the fuse box. This gets 12V from the accessory fuse inside the car by feeding a cable from this bus bar to the back of the fuse next to the driver's footwell. Advantage are that the DRL is on day or night; there's no power wastage; the LEDs are brighter; and the error doesn't appear whilst driving. Disadvantage: Can't disable DRL if want to; error still shows up when starting car; bulb warning light in dash remains lit

Now this is odd. Why am I still getting a bulb out error for Left & Right DRL when I have disabled them. In fact, for a week before finalising the setup, the LED DRLs were not connected to anything and the DRL option was disabled, yet I still got the error on startup.

How can I stop this error as I have now disabled DrL so the ECU shouldn't be checking the circuit for current. The DRL wires terminate to an open circuit (brown & yellow wires feeding the DRL location are not connected to anything). I'm guessing this is a VCDS issue. Unless the brown or yellow wires are supposed to connect to something else?
