The fact that the light bar lights up means that it works. If the fault is consistent, I'd be more tempted to look for the fault at the brake pedal - where the switch for the light is. As your existing brake lights work correctly, next step is to see whether they use the same switch, as per @Brian's comment. It may be that the LED bar has been wired in ...

A blinker relay uses a thermal switch which is a piece of curved, spring steel and a thinner piece of spring steel near it that has a wire coiled around it with a resistive property. When current is applied to the relay the coil of wire heats up and expands the small piece of spring steel until it pushes it to make contact with the larger piece of spring ...

After much deliberation on going to repair shop, I figured I would at least poke around as it could not make anything worse. Here was the problem. The negative terminal wire soldering point was loose. I fixed it this way: Unplug the LED array. (Pictures to come) Video of removal process here on youtube Remove the rear plastic shroud(with a few upward ...

That's actually standard Audi & VW behaviour, not an electrical problem.

A good service manual will have extensive wiring diagrams and possibly troubleshooting procedures and connector locations. With that and a multimeter, you can easily track the problem down. I prefer factory service manuals over Haynes / Chilton / etc, but they're not cheap. Looks like the one you would need would be $150 from Helm. If you can verify the ...

I found a copy of the owner's manual here. Pages 284-285 have a diagram of the instrument cluster, where this light appears as #17. Page 294 says that this is the Vehicle Security Light and explains: This light will flash at a fast rate for approximately 15 seconds, when the vehicle security alarm is arming, and then will flash slowly until the ...

The hazard lights in every car I've ever drive work whether the engine is turned on or not. The turn signals (indicators) work when the engine is turned on. It sounds like something is interrupting the power going into the turn signal switch when the engine is running. One possibility is that the alternator isn't working and so the engine is lowering the ...

Since it is occurring on both sides with the same result, your problem lies with the switch on the column. There is an outside chance that the wiring harness connection which attaches to the switch might need reseated, so you could attempt that as well.

In my particular case, the cause seemed to be low oil and an oil weight too heavy for the temperature. I only checked the oil level so late because my low oil light never came on, so the oil must have been low enough to cause pressure drop, but not so low as to trip the oil level sensor. Also, I see reports online of 10W oil being too heavy for temps ...

I'm thinking, from your description, that the problem is the blinker relay, not a fuse. The lights themselves should go through the tail lamp fuse. The relay is what gives the characteristic ticking sound. The emergency flashers usually run off of a separate blinker relay, but may be the same thing. If so, you can use it to test between the two. These relays ...

There's a chance the relay needs to be replaced. There's a couple steps you could try beforehand though. Check resistance between all the wires from the light controls to the relay to the light bulb itself. As long as there's zero to very little resistance you know all your wiring is ok. You can clean the contacts. Use some steel wool and/or sandpaper to ...

Agree with @mac & @ChrisMcKeown ... one of your sensors is telling your computer one of your wheels has stopped spinning and therefor is activating the traction control. Figuring out which wheel sensor is bad will be tough to figure out. If you don't have the right diagnostic equipment available to you, it will require a trip to the mechanic to get it ...
