![]() The central warning light appears in two colors, yellow and red. Here's one of the hints that will help you understand the scale of the problem: the color of the light indicates the severity of the issue with your Volkswagen. What Does the Triangle with Exclamation Point Warning Mean on a Volkswagen? In this article, we will explore the most common reasons for the central warning light to be illuminated, as well as how to fix this problem. There will also be a stored error message in the car's information center and the code in the ECU.īecause there are a broad number of reasons why the central warning light comes on, it can be difficult to figure out the cause of the problem. It indicates that there is an issue with the car that requires attention and usually appears along with another light or message that specifies the problem. When this light comes up, it informs the driver that there is a problem, and some action is required on the part of the driver. The triangle with the exclamation point in it is the central warning light. ![]() What's this light, and what does it mean? If you drive a Volkswagen, you may have noticed that a triangle with an exclamation point tends to come up with other warning lights. Some of them seem to indicate major issues, while others seem to come up for no reason at all. However, there are so many of them that it seems impossible to understand what they all mean. Subsystem 1 - Part No: 5K1 955 119 Labels: 1KX-955-119.Understanding the dashboard lights and warnings is one of the most important things a driver needs to know. ![]() Status: Malfunction 0010Īddress 09: Cent. This means the mounting and location of them is important from a safety point of view so that any heat can be properly dissipated without the risk of something being melted. However, be aware of the heat that some of these load resistors produce. This then fools the BCM into thinking that everything is OK. The alternative is to fit some of the large high wattage (~50w) load resistors that you connect in parallel with the LED to create a bigger current draw. So whereas some of the earlier cars reportedly don't flag up errors with certain error-free CAN-BUS LEDs, you can find that the later cars don't necessarily work error-free with the same LEDs. Also, the newer VAG cars unfortunately seem to have a more sensitive bulb error detection system on them. However, even some of these turn out not to actually be error-free so it can end up being a bit of a trial-and-error exercise to find some that do actually work error-free with your particular car. You may end up having to admit defeat with your only realistic option being to use error-free CAN-BUS LEDs. This means if you decide to try and play around with different byte 18 values, you have no idea what original value to set it back to again if your attempts fail. On some of the older models there were some "Cold Bulb Diagnosis" options under byte 18 that you could switch on and off but those seem to have disappeared on the newer cars, and to make matters worse, the undocumented "magic byte" 18 now appears to be masked with "00" so you don't know what it's actual value really is. When using the Central Electronics long coding helper, do you see any tick boxes for byte 18? I suspect you probably don't. New to VCDS but I am learning quick, please help! What I would like to do is eliminate all the Light malfunction for the lights I have put in as well as future ones I put in such as the tail light bulbs, fog lights, etc. Headlights: Halogen (confirmed by Zircon): Access it in VCDS via 09-Cent Electrics -> Coding 07 -> Long Coding Helper -> Byte 18. In all cases, the byte to code is byte 18 of the Central Electrics module. ![]() Here is a summary of the information I've tracked down from various reputable sources (including my LED supplier), regarding the recoding required to remove the bulb-out warnings that are raised when regular tails are replaced with OEM LEDs. The codes in VCDS are for the front side parking lights are 02394, 02395 and for the reverse lights are 01518, and 01519.Ĭentral Electronics Component: BCM PQ35 M110 0651Īll I have found from looking around it this: I installed LEDS in the front side parking lights (inside the high beam housing), license plate, and the reverse lights. Can anyone help me with eliminating the dash Light Malfunction Indicator.
